- When a fan asks Neil deGrasse Tyson what would happen to our Solar System if the Death Star from Star Wars blew up Mars, Neil goes one step further and explains to Eugene Mirman the physics of how you might actually go about blowing up a planet. (If you're planning a career as an evil genius, mad scientist or cosmic conqueror, you may want to take notes.)

Dimbass American military have already answered this question
Stupid autocorrect. Butt wipe
StarTalk Radio was hoping Neil would clarify or explain further why a planet [or any thing?] blows up if a specific minimum amount energy is 'added to it' - ie energy above the total nuclear energy of its atoms? I thought it blows up when a force impacts it cutting or shearing or disrupting the planet [body]. Mananna? Next time perhaps?
This is why I like this dude, he answers questions I didn't even know I was asking.
electrify the sea you'll distroy the electromagnetic field of the earh and that's it.
New Video: Watch Neil deGrasse Tyson tell Eugene Mirman how to blow up a planet in this Cosmic Query. If you're planning a career as an evil genius, mad scientist or cosmic conqueror, you may want to take notes: Neil deGrasse Tyson: How to Blow Up a Planet
I'm pretty sure watching a vid called 'How to Blow Up A Planet" is going to put me on _several_ lists.
Jonathan Warden
Then our work is done, Jonathan.
OK now we just need the necessary equipment to do so. Lets blow up Pluto, and rub salt in the wounds of the "Pluto is a real planet" club!!!
+Gareth McKnight Heck yeah!!
Gareth McKnight Why!!! Pluto is now planet since 2017!!! 😥😢😰😓😳😦😯😠😡😖😣😭😭🤢🤢😭😭😭😞😔😟😕🙁☹️😣😖 ⚔️⚔️🔌😐😵😑
@ 0:15 the host tries to imply that he's not familiar with Alderaaan, meanwhile at home he has every lego star wars ever produced and plays with them daily.
I love the fact that Neil actually took this question seriously and gave it a serious answer. That's why he's my favorite celebrity above any actor or athlete.

Neil looked so offended when Rover was brought up.
All it takes is a power level of 300. I, alone, have a power level of over 5,000. And Nappa, here, has a power level of about 3,000. That damn Kakarot has a power level of OVER NINE THOU... nevermind.

Oh, please. You Earthlings over-complicate everything.

lol frieza don't make go super saiyan on you again.
Kal i read this in frieza's voice 😂
To be fair, even Yamcha can do a lot of damage to a planet. We can flex tape it back together though, no biggie.
@@andrewpliakis To be fairier, even Puar can do a lot of damage to a planet, transforming into Death Star.
Thanks for the shoutout about EPAP. Some pretty sweet stuff.
Three downvotes... survivor guilt, because these Alderaanians weren't home on the big day. 8D
Is there full video uploads of startalk on youtube?
Great audio quality
Find a way to create anti-matter out of + matter. Such a beam might slow down when it hits a nickel/iron core, as denser materials would take longer for conversion. A few grams of antimatter would literally destroy the earth if detonated with + matter, so it wouldn't take much.
veronicats100 Mars gravitational influence is basically not noticeable 600.000km away from it due to the sun's gravitational pull being so imense. And earth is 56.000.000km away from Mars during the phase of both planets coming closest to each other.
Love this guy!
Darn it I wanted to become the Martian Manhunter...
Awesome video as always!

Alex Robinson from the Star Wars Minute? Small world.
The real question I’ve never seen anyone ask is why didn’t the Empire just destroy Yavin instead of Yavin 4 (To those that don’t know, the rebel base was on Yavin 4 which was a moon of a gas giant not unlike Jupiter. The Act III tension of the original SW movie centered around the Death Star being required to enter a powered orbit around Yavin in order to obtain a clear shot at Yavin 4, where the entirety of the Rebel Leadership and a good portion of it’s combat machinery was hiding. This presented the Rebellion with just enough time to mount a counteroffensive and destroy the Death Star.)
Would it not have been equally effective to destroy the gas giant itself? What would be the result of that on the moon, assuming it wasn’t consumed by the resulting explosion? I’ve always assumed it would arc off into the star system to either be recaptured by the host star or, if conditions were such, it would be flung off into deep space, correct? Also, what would be the effects on the local environment on the moon itself if the gravity of the gas giant were suddenly removed?
Anyone out there know these answers?

Anything with mass can have satellites, the problem is perturbations of those satellites' orbits due to other bodies. If you put a fist sized ball of lead in middle earth orbit, so the atmosphere has less of an effect, you can have peas orbiting that no problem. Their orbital period will be quite long though, since the masses involved are so small.
Why can't we get the audio feed from the studio mic's? It sounds like we're getting the audio from the mic that's built into the camera and it's picking up ALL THE SOUNDS!
You're welcome! Spread the word ;)
Measuring the tides is a bit unfair though, since tidal forces depend on smaller distances that give rise to large differences in gravitational force on two sides of an object since gravity diminishes by the inverse square.
Anyhow, Mars is to small and to far away to change our orbit significantly, as you said. (although measurable).
electrify the sea you'll distroy the electromagnetic field of the earh and that's it.
gravitational fields decrease exponentially the further away you get from its source
I tweeted the same exact question to him.
This is definitely going on my favs list. lol XD
So, what do you have to say about Neal Stephenson's new book, "Seveneves?"
*steeples fingers together*
Excellent.
Tyson is a preeminent astrophysicist. He knows a lot more about it then anyone who commented here. Yet you are positive he is wrong. You made a guess without any evidence or understanding of physics. I will go with Tyson on this one.
electrify the sea you'll distroy the electromagnetic field of the earh and that's it.
The gravity also doesn't just disappear. We would still experience the gravitation from all of the martian particulate in a relatively smooth function.
Well the dynamics of the solar system will change, but not significantly I think and at least not in the immediate future. The debris will still orbit the sun in roughly the same orbit, so it will still have a comparable gravitational effect on other bodies in the system until it gets spread into an asteroid belt or clump due to various orbital resonances, not sure how exactly that works. Mars is about 3000 times less massive than Jupiter, so it has less effect on the orbits of other planets.
Even though there is a lot of mass in Mars, space is big. Very big. Yes, we will see big meteor showers. However, the likelihood of a chunk, large enough to do serious damage, hitting earth is still small. How small depends on many factors. Generally, the more energy used to blow up Mars, the smaller the remaining pieces will be, and the faster they will be going. They might even achieve escape velocity from the solar system. We are talking about a *lot* of energy.
I still love the retro sf stories where aliens remove a planet from the Solar System (usually Earth, usually with a kind of giant tractor beam). OK, I'll buy that. What gets me is how, when the heroes destroy the beam, the planet always returns to its original orbit.
Well, when Doctor Who did it he got the Earth back into place with the Tardis.
If we place corks on top of the volcano peaks we can create enough force to blow up a planet?
Science is awesome
To blow up mars all you would have to do is get tons of
(Potassium Nitrate) next you would need tons of
(Powdered Metal) all metals are explosive once you grind them up into powder. But the particle size has to be the consistency of baby powder. For it to be at it's best. So yeah, i would just use tons of aluminum sheets grinded up into a very fine powder using a tumbler machine. But the problem is that it would take forever to create that much explosive powder. But anyways, next you would have to mix your aluminum powder with the Potassium Nitrate that you also grinded up to the consistency of baby powder. Next you have to drill a hole into mars that is the length of it's radius, a hole down to the core. Next you would have to pour your powder mixture into mars. Next is to stick in a fuse and light 🔥 it up and in no time, mars will be gone! Yes i would just use (flash-powder) very simple.
Neil deGrasse Tyson knows how to get my attention with a title!
So blowing up a star.. will be same or different than blowing up a planet???.. what method can we apply for that?.. anyone
Physics 102 - How to blow up a planet
That course is going to be essential if I want to become an evil genius.
I have a question, how big would a man-made object made of solid lead need to be to have its own satellites, and how far from Earth would it have to orbit.
Mars' contribution is insignificant to that of the Sun.
Interesting someone mentioned Jupiter.
I think you might actually need less energy to blow up jupiter than you would Mars.
Jupiter would then turn about 7% of it's mass into energy and do the rest of the work for you.
Getting rid of Jupiter would not screw up the system because of gravity. The other planets would continue on in their orbits, just without the perturbations caused by Jupiter.
However, because of its size, the energy required to "get rid of Jupiter" would be so great, that it would vastly out shine the sun, like a small super nova. Although short lived, it likely would be enough to exterminate all life on earth.
That's true, but it's hardly unfair... what other effects other than tidal forces would a gravitational body have on our planet, if we're not orbiting that body?
Someone else mentioned that Jupiter acts as the vacuum cleaner for comets and asteroids, that's something. Mars is too feeble for that though.
So really? The loss the mars wouldn't cause a change in our orbit or the orbits of the other planets? There wouldn't be any environmental shifts/changes as a result of the the loss of massive gravitational anomaly we formerly referred to as Mars? Interesting, I would have assumed otherwise... I was under the impression that all the massive bodies in our solar system indirectly acted upon one another.
Brb just gotta use my Dr. Device on the Formic home planet #endersgame
You ask yourself how much energy is keeping it together? Than you put more than that matter energy into the object. Then it would explode. That's the lesson.
wouldn't the rubble that used to be mars just re-condense over time? You might get a planet/object smaller than mars because not all of the bits would come back, but some of it would probably condense back together.
In a theoretical, closed system where no other force will act upon the Mars' rubble.. then yes. But that's not the universe we live in. The rubble is going to be scattered in every direction and tugged on many different sources of gravity of differing strengths in just about every direction. Some may settle back in it's original spot or it may not, Mars blowing up would have a gravitational effect (although practically unnoticeable here on Earth) on the balance of the rest of the solar system as well since said mass isn't concentrated in the same volume of space in the same configuration as before, even if all mass and energy is conserved.
But keep in mind all the debris from Mars would scatter miles away from each other. It may form small pebbles then into rocks but other than that it would probably just wander off somewhere else
The planets do interact with each other, but Mars is tiny really. It's gravity doesn't have that much effect on Earth or the other planets. Now if you get rid of Jupiter you can really screw up the system :P
Mind you blowing up Mars still means Earth is screwed, not because of a change in our orbit but from the chunks of rock that will eventually crash into us. Mars is not a big planet, but it's still a lot of material there, we're talking about one hell of a meteor shower here :)
Who the hell are those people in the back. I see them in every video.
blowing up any planet it would change and affect everything especially mars
If we have a Death Star, I think we could afford to lose Curiosity.
Q: how do you destroy mars?
A: completely destroy it
Aha thanks yes, now I see…
Exactly as DavenH pointed out, it would had practically no effect, Mars is too small and its mass effects other planets very little. With Mars gone the center of mass of our Solar system would shifted for an unnoticeable amount . Realize that 99.5% of mass in our Solar system is in the Sun, so even if you blew up the Jupiter there would be the same result.
Letting out a fart causes a change in our orbit. Thing is, it's so insignificantly small that we couldn't measure it and it almost doesn't matter. The same thing would happen if Mars were to blow up. Sure, we could actually measure the changes, but they'd be minuscule.
If you just look at the orbits that can not be the case.
If we use the minimum energy required to destroy Mars,then from a distance of 300 million km, every square meter of Earth facing the explosion will be blasted with an analogue of about 1 kg of TNT. Doesn't exactly sound harmless.
Mars's core cooled down too fast and it lost it's magnetic field. That allowed the solar wind to strip away most of the atmosphere over billions of years. That's why it lost it's atmosphere not because of collisions in the Asteroid belt.
Losing mars would cause a change in our orbit that would be measurable but insignificant. Mars is massive but not compared to the sun.
that's the best smart humor ever.
If you cannot go to Mars, you can make Mars come to you >:D
Not even close. The tidal forces from the gravity of Earth would dwarf by many magnitudes the gravity of a fist sized ball of lead. Even the gravity of the Sun (and Jupiter) within the solar system would perturb such a delicate system. If the ball was out in interstellar space it would work.
Hmmm? what he said does not sound correct. Mars definitely has a gravitational affect on Earth. It almost definitely would have some affect and I recommend we do not try removing Mars even if we could. The solar system as it is seems to be very stable, and I would want to keep it that way. Possibly the material of Mars would not go far from its orbit and would probably even reform so the affect could be very minimal.
+randomuser942464 Mars is 401 000 000 km away from us (239 000 000 miles)
Illudium Q-36 Explosive Space Modulator is what you need to blow up a planet.
I'll save you guys a couple minutes. All you need is a good ol' fashioned ki blast.
I don't think you appreciate the distances in our solar system. Neither do you appreciate how orbital dynamics work.
If Mars exploded, the debris would mostly follow the same orbit. Preservation of momentum and all. Some debris would get flung out, but chances of that hitting us is minimal since you are ADDING energy, thus the orbit will be larger, not smaller...
Small chuncks will hit us, but the chance of anything big enough to matter hitting us is really small.
Mars lost it's atmosphere due to the planet between Mars & Jupiter blowing up plus no one could blow up a planet without being taken out first by others over seeing our human development.
There was no planet between Mars and Jupiter, and it didn't blow up either.
The "Exposing Pseudo Astronomy Podcast" episode 29 and 30 cover this subject, debunking every aspect of the story.
I recommend you Google it and give it a listen. It has good, solid sources and is explained without BS.
I'll be sure to inform my superiors about this...
I was under the same impression...
Wouldn't a large chuck of Mars hitting Earth negatively effect us in a major way?
depends on how mars blows up. If it blows up starwars style, it's be a cloud of dust and small debris. That would only have minor effect on us and zero effect on earth. If mars would break apart due to whatever influence and a large chunk hit us, we as human beings would probably toast, as pretty much the rest of life we know. But that wouldn't mean the end of earth. Earth already survived one collison with an object about the size of mars (the proof of that is our disproportionally large moon consisting mostly of the same materials as earth).
I did ask about a large chunk of Mars hitting Earth. Obviously if it was turned to dust impact events would be minimal. I wonder what all that dust might do to solar radiation over the next few years/decades/centuries.
Phil Heaton
you should read my whole comment and not only the first sentence...
I wonder if a super powerful laser would do the trick. I think if you beamed such a laser at a planet like earth, the inside would warm up so much that they would expand and maybe even become gas, than the planet would blow up due to the rapid expension of it's insides.
Good luck on that. There is no energy that I can think of to produce such damage. And it's probably going to take more than decades. Probably impossible to be honest I mean its not going to even touch the planet. The laser would probably just point it's ray at it and those rays would scatter.
Thank you for sharing your thoughts on the matter.
Don't you think that, for example, microwaves could in principle do the trick? They work pretty well in my kitchen for warming stuff up ;)
Leaving aside the energy needed. Or would they first warm up the atmosphere so much that nobody would notice the continents being teared apart by the expanding liquids and gasses of the earths mantle, because everybody would be already gone? Or do you think you couldn't, even in principle, blow up/scatter the earth using concentrated em radiation?
+Maarten DJ The concept isn't bad and microwave is the second most energised form of light but maybe it would scatter out before meeting the surface of a planet.
+Maarten DJ although a consistent laser might work. Not a huge ray of light laser type. But the problem with that is it might not be that benefit able
GRB at close range 😂
if mars blew up then the solar system would have a new debris field made up of rocks of various sizes
Notice how much the tides rise when Mars is in the night sky? I don't either. It's too far away to be of significance.
"There was no planet between Mars and Jupiter" I hate to be a bubble popper but in my field in finding information there was...... Here's the bubble popper ( like telling a child about Santa too early ) how about you google "The Psychic Twins ,Dolores Cannon & Mellen Thomas Benedict. The world isn't what you think with no bs.
If Mars were blown to pieces, would a 6 mile diameter chunk of rock or metal come towards the Earth? Would that affect us?
+manikhat sarcasm
Get Red Matter
Mars is too small and too far away. It might cause a liiiiiiitle change in our orbit over a very long time but it would not be significant compared to other variances. Jupiter might be another story, it won't change climate over night either, but that might have so larger effects on our orbit and will change the dynamics of asteroids and comets entering the inner solar system.
For explode mars or earth how many H bomb do we need?
please someone do the math...
The gravitational binding energy of the Earth is about 2 x 10^32 Joules. The estimated energy released by the most powerful nuclear device ever detonated, the Tsar Bomba, was 2.1 x 10^17 Joules. If they were all placed at the center of the Earth, denated, and all the energy was absorbed into the Earth, it would take about 952,000,000,000,000 Tsar Bombas to destroy the Earth.
Thanks!
@^_^@
Hunter Campbell congratulations, you just gave korea a idea.
Hunter Campbell
the gravitational binding energy for mars is approximately 2.4x10^31 but ye, there should be some tensile strenght of the rock aswell (that i have no ide a how to even approximate :) )
***** so thats the diference between nuclear and atomic bombs, I always wandered.
How to blow up a planet
..Be a super saiyan.
It wouldn't affect any planet in a measurable way.
Nope.
Jupiter on the other hand..
Yes but
A) Very expensive. $10,000 per pound of garbage expensive.
B.) Possibly dangerous. Bacteria/harmful particulates could filter and fall onto populations.
C.) Just because the atmosphere is doing the burning, doesn't stop the release of CO2 when dealing with organics which is a greenhouse gas. It will not help climate change.
D.) Some metals and alloys could survive re-entry especially being condensed and cause some serious damage when landing.
I'd be more worried about what would happen to Phobos and Deimos should Mars get blown up.
Maybe they would have a bit of gravitational field and the attraction between them would make them closer to each other and there would be one of the moons stay still and another moon orbiting that moon
+xBluR Plays let me add to that. It depends I think on which moon has the most mass. The moon with the most mass would be the moon which would stay still. Since it has more gravity it would attract that other moon to orbit the more dominant moon in terms of mass. Hope this helps you
if mars blew up one day we would be panicked.
I wonder what you said about blowing up planets are true.
Why would it not?
xBluR Plays Idk? I just wonder if there is a way.
GamePlayer4264 Well Neil said himself that it was possible and gave out explanations.
xBluR Plays Well I might believe in it.
GamePlayer4264 Alright...
Nice but you didn't answer the question. Without Mars in its orbit when it's gone will the other planets orbits shift to make up for the loss? I f so would we die?????
Maybe less gravitational field but it wouldn't change other than that.
massive bodies in our solar system indirectly acted upon one another
brb gotta do stuff entirely not related to blowing up planets ..
Someone call Freeza to blow up Mars
Why go to Mars when we can bring Mars to us:-)
Damm why mars come on lets do it big time blew jupiter.
If you blow Mars up wouldnt that affect our orbit around the Sun?
***** ***** ***** Raheem Plummer I love this guy.
Miles W Yeah, this guy is awesome.
I know him from Cosmos A spacetime Oddysey.
*Nice video. Interesting question regarding Mars, too. To go on further, the only planet we need to really worry about if it was destroyed is Jupiter.*
***** Yeah. In the future when the Sun turns into a red giant and goes back into a white dwarf star, the outer planets starting from Jupiter would still survive. It'd be awesome if we could somehow like on one of Jupiter's moons.
***** Oh, so if Neptune were to blow up, would Earth be fine?
I have the power of a demi god telekinesis if you must say so i'm going to fuck this planet up
there is a mouse on that planet.....
blow it up
(Caution!)! Don't do this at space!!
Show me a dishonest politician and I'll give you three jars of cookies and 10 million dollars.
isn't mars extremely radioactive? because it has very little atmosphere to block the suns radiation?
Nope, the atmosphere is not that shin, and to get something to be radioactive you need to put the nucleus of it's atoms at some exciting state. For example you bombard an object with neutrons and some neutrons get captured and then they decay slowly over time. You can think of radiation as a light. When you go under the sun do you glow in the dark? No! Because you were bombarded with light and it scattered off of you, giving you some of it's energy. Most of the radiation is exactly the same as light :)
The person will never glow in the dark - the killing dose is 1000 times lower than a dose that will make you strongly radioactive for a long time.
so then why do i always here that any moon/mars colonies would need to be underground?
morgan organ That's due to solar radiation, specifically ultraviolet light emitted by the Sun, which is dangerous to living organisms because it's known to cause cancer, among other things.
The surface of Mars is not (very) radioactive itself, so if you took a chunk of Martian rock from the surface, it wouldn't emit any kind of radiation. In other words, Mars does receive radiation, but the planet itself is not radioactive.
+Fiainn Indeed. And if I can add to that you will need oxygen molecules somehow to rise into the air and the ultraviolet rays from the sun would split them into 2 or 3 oxygen atoms to create and ozone layer. Although they will need plants or water splitting oxygen from hydrogen and releasing the oxygen but it would take way too long to even think about. At the moment in this time
I was thinking the same. I disagree with Neil here.
XD
I swear this world is like the movie silent hill they killing and lying about everybody that got telekinesis you only got it if working for them
