I dont think that many people know the 42 thing...

It would be impossible to go through the earth, eventually you will hit bedrock and cannot break it. Even if you go to creative you will just fall in the void.

Ah yes, terminal velocity, slow and boring.
in an endless black tube of nothing but temperature variation for more than half an hour? there's not even air in there and the sensation of falling only applies while youre still accelerating at a noticeable rate.
after a few minutes you wont feel, see or hear a thing.
Terminal velocity is something caused by air friction, which is taken out of the calculations like he said at the beginning of the video
Yes, ok. you are TECHNICALLY correct. happy? :P
jamham69 Yeah, you wouldn't feel, see, or hear a thing. You also wouldn't be alive.
If you made the tunnel, allowed time to fill it with air, then jumped in, air resistance would limit your acceleration to terminal velocity. But after passing the center of the Earth, your momentum would be competing against gravity and wind resistance. You'd never make it to China.
next time someone texts you and say they're falling for you, make sure you dont take more than 42 minutes to respond to their text otherwise they might be over you. literally
You deserve a cookie
what kind? :-)
Would chocolate chip cookies suffice? :)
yes. yes it would.
when the cool kids try to talk to the nerds. :P
Would you actually end up coming out the other side if you fell like this? Wouldn't you just begin and oscillation back and forth, never quite reaching the surface again, losing energy each time, until eventually you're just stuck in the core?
breadman86
If there is no wind resistance, then you shouldn't lose energy in the system, meaning that you should end up on the surface again. Unless there's somewhere where you can lose energy.
And you’ll fall out the other end at the same speed you fell in
There have actual projects to make gravity powered railway elevators. The earliest rail systems, like a few in England and Wales, used gravity to transport large cargos. So long as both points were at the same True Elevation, counted from the core rather than sea level, you would come to a perfect stop just as you arrive... But have only a half second to grab something, or you will be returned to sender.
@@williamd6621 At the beginning, you have a whole lot of potential energy and no kinetic energy. As you fall, your potential energy is converted to kinetic energy, until you reach the centre and have a whole lot of kinetic energy and no potential energy. Falling out the other side, the reverse occurs - kinetic back to potential. With no air resistance, all that energy would stay in the system, just converting back and forth between the types.
No, you have enough energy to keep on going.

"Constant stuff" Very scientific!
+JustJason Actually physicists say things like that all the time :).
+ninjafruitchilled A few teacher that taught me did that, couldn't help but laugh
That term is used in mathematics very commonly.
Why wouldn't you say constant stuff. They're just a bunch of numbers which when calculated resulting in one number, this number says very little scientificly about a formula
+JustJason it's justified because "constant stuff" doesn't change the nature of the curve, a linear function times a constant is still a linear function. Linear transformations can be done at the beginning and the very end to make sure things are in agreement (e.g. the unit system), but don't really matter when it comes to finding a strategy to reason about the equation, in that respect they serve only to distract and potentially introduce calculation errors.
Think about this- you will be upside down when you will reach the other end of the earth
What
not if you jump in head first
if you reached the other end won't you just go back down cause you're upside down?
-If I am not mistaken, Newton's 3rd law allows an object to apply energy onto itself to rotate it around it's center of mass, as long as it doesn't change the center point.-
Jithesh Dsouza unless you dive head first
I like how every physics problem ever always goes: let's assume that things are not what they are in real life.
You need to solve fort for the special "Clean Case" to figure out what formulae you are going to use, you then get an answer to help later when you add in the messy RL stuuf, and you can compare to see if you answer for messy life is close to the clean case, or if it is orders of magnitude off.

If your real-stuff answer is way off the clean case, you may need to reassess your assumptions and math.
@@MonkeyJedi99 I know. It's just a joke. We all went to school, my guy.
0:17 "Ok Peter, since you're daring to question my claims, I'm going to explain every last detail as to how I know what I'm talking about here. You ready? Here we go..."
I'd rather jump honestly...

That sounds so morbid out of context.
In context too, since you'd die if you jumped in the hole.

I suck up all the information that I encounter, but hardly ever let anything exit my mind. It only happens in the form of Hawking radiation, when one of a pair of entangled particles (like your comment and my reading of it) enter my mind.

Did you even read the hitchhikers guide to the Galaxy
I watched it does that count
no
did you even read the sequels?
Ziggy Stardust yes
This seems odd to do without integral calculus
+Mandragara He sneaked that in under the radar by skipping straight to the solutions of a simple harmonic oscillator :p. You would need to do the calculus in order to get those solutions, or to otherwise solve for the travel time.
+ninjafruitchilled as many wise people have said the best scientists just steal other peoples work. why mess about with calculus when someone has already done it for you
+Sam Winton Well the main reason would be to properly understand how it works. Also in this case it isn't very hard. But it would be a bit too far beyond what you could expect an audience to follow in a CZcams video, so it is clear enough why he didn't do it.
+ninjafruitchilled fair point. Ive done A level physics so the video was pretty simple to me. If calculus had been included i would have been screwed 😂
+ninjafruitchilled I was kind of ridiculously happy when he skipped the (double?) integration though.
My physics teacher had us explore this question in high school, like this video he really made learning fun and I wish more teachers were like that.
Good thing I don't go to school :D
It is also worth mentioning that, assuming Earth has constant density, it doesn't matters if you are falling through the center of the earth. You can go a little bit sideways, it would be also the same time. Or even completely sideways. Like trying to dig directly from London to Paris. If there is no friction with ground and if you will just jump in the hole, you will also arrive in ~42 minutes
I prefer 42 minutes because of Hitchhiker's guide to the Galaxy.

if I got thes right:
r = 25362000 m
roh = 1270 kg/m³
t = 88 min
I don't get why we can cancel out everything that's obove us in the "shaved earth" model: the gravitational force depends on how far you're away. That means that if I fall straight into the hole, the part above me attracts me much more than the part opposite the earth pulls me down, because one is much closer than the other -> smaller radius, more attraction (G*m1*m2/r^2). Is my question clear?
Don't hit the side of the hole
and when you come out the other side. you are upsideown

The fuck is a penualamum thank goodness you put that cat in the parabola because I would have been so lost
A pendulum is simply a weight on a string or arm that is allowed to swing freely. Like a clock's swinging weight, or a swing in a playground.
They are pretty simple to calculate how they behave, and are a good introduction to things that constantly change speed and oscillate, so they tend to be found in beginner physics classes.
+Ravaxr lol I thought my sarcasm was pretty obvious but thanks for the definition anyway
I have seen completely serious posts display stunningly inept questions before, so I assume people are serious when they ask a question. If they are a poe, then okay. The next person to see the thread that doesn't actually know gets the answer for a question they don't have to ask anymore.

Awesome video, thanks!
Just so long as no one turns around and says "why haven't we built this yet?!". I've had to explain to someone that this is not pragmatic, and never will be in the conceivable future. We're talking about drilling a hole through the mantle, through the core, through everything that idles at incredible pressure and heat. We and our perceivable future selves cannot deal with that; we can't even dig more than a few km through the crust before our best equipment starts to break down. And our tunnel has to endure the internal forces of the molten core not only squeezing it, but also moving around inside while the continents are moving at the surface (albeit both at a geologic pace, cm per year; but there's no super-ancient society that built tunnels through the earth for us to ride). And the Coriolis effect makes the ride down difficult. And then you need to survive the heat and pressure during the ride, not just the equipment. And.... Okay really there's no point enumerating further. But sometimes people read sci-fi stories and think they're an authority on the subject.
So yea it's not realistic. Same with pushing the end of a pole that reaches between planets to produce faster-than-light communication... just no.
I would like to see the function of g.
Or is the "pendula"-equation already the solution to this differential equation? It wasnt really clear, whether you used g as g(t) or g(R)...
Oh come on, be honest now. It took you much longer to calculate all this stuff than 38 minutes and 6 seconds.
If you say, more time, then I'd say much less death.
+Penny Lane No it's pretty easy... i'm in last grade in france jsut before my graduation and all the physics calculations you see that here already and it's pretty simple.
the only long part must be gathering the informations about density and stuff, after that its just aplying formules and math magic :)
HolyBookProductions I think she was sarcastic.
HolyBookProductions I'm not saying it's hard. I'm just saying it'll take you longer than 40 minutes to do the non-simplified calculations. And yes, Aditya Khanna has a point in that I don't actually suggest jumping into a tunnel through the Earth that doesn't exist to save time. Primarily because most stop watches don't cope well with the pressure and the heat.
Penny Lane I doubt stopwatch would be a problem (it's least of our concern). There can be two people on opposite sides, with stopwatches.
And actually, it takes less time for a pro physicist!
Of course it is 42 it is the answer to life the universe and everything
The reason Douglas Admas chose 42 is MATH if you convert the letters in MATH to numbers M=13 A=1 etc. they add up to 42

Of = 2. course = 6. it = 2. is = 2. forty-two = 9. it = 2. is = 2. the = 3. answer = 6. to = 2. life = 4. the = 3. universe = 8. and = 3. everything = 10.
2+6+2+2+9+2+2+3+6+2+4+3+8+3+10 = 64
Sixty-four = 10
Ten = 3
Three = 5
Five = 4

I love this. It's pretty logical, expect the fact that to drill a hole through the earth, you'd have a bit of a problem, since the two parts will pull/push you in a non spheric way, which makes it a hell of a lot more difficult.
Hey, great video, thank you. Maybe you could add some extra info to make a bit more complete: what is the top speed you'd reach, the expected temperatures as you fall, maybe a simple vídeo showing the moviment if you jumped from the equador... Hum, maybe the terminal velocity considering air friction, so as just to show how far from the center you'd get, after crossing the center, in a more real situation. (I'd skip the air density change factor, but that's up to you).
Thanks again!

Of course it takes 42 minutes to fall through any sphere. You don't have to do any calculations to figure that out.
So it takes 42 minutes to fall through a 30 feet sphere?
+nimbuzz obviously
+nimbuzz If its density is that of the earth yes. Keep in mind a 30 feet sphere wouldnt exert much gravitational pull on you tho. Math is neet
+nimbuzz
If no other force is present, yes.
+nimbuzz if in space and depending on the mass of the 3 feet sphere, maybe.
There is a ton of interesting stuff about this topic. There is a paper not mentioned in the description where Alexander Klotz pointed out how the rotation of the earth will affect the shape of the tunnel and the falling time. And he made some simulations. Search for "The Gravity Tunnel in a Non-Uniform Earth" by Alexander R. Klotz.
3:18 I mean if you think about it the radius of the earth does factor in because density is mass divided by volume in volume is directly proportional to radius cubed
I'm not sure why you're using a round earth model when it's clearly flat. Do some research on CZcams it'll change your life

"Mathemagical dust" is a wonderful phrase. In fact, this video was mathemagically delicious.
Hi
I have got a question!
If the earth's center point would be an empty room, and I were in that room would I floating? Because thats the center point of earh where the gravity is pulling things to, but the surface if earth is there and the things cannot fall into the center of the earth. So what would happen if sy were in that center point?
Please make more videos like this one, it was really interesting and I loved how you showed all of the calculations.
Thank you for this video!
I love how you explain the concepts of physics, but to see the maths that goes behind it is very interesting, and something that I believe is lacking in many science-based CZcams videos. I know many may quickly lose interest when the maths takes over but I know there are many people out there, like me, who enjoy it.
So please make more of these videos!! :)
Did you draw all that that's impressive!
I was wondering if it's possible to calculate the time of falling without using the formulas connected with the pendulum stuff, however since the acceleration depends on distance it seems to be hard. Is it possible?

If we actually jumped into the hole, we would vaporize long before we reached the center, due to the extremely high temperatures.
+Physics Videos by Eugene Khutoryansky And I always thought, the core is made out of happydust and unicorns.
+Physics Videos by Eugene Khutoryansky No air though, so would have to rely on IR for heating alone.
Sorry if I ask something incredibly dumb but shouldn't the extremely high pressure cancel the high temperature out? Or at least close enough. Your body would boil and evaporate if at sea level pressure.
That's not used as a factor in the video though, temperature doesn't matter because there is no air to transfer it. All factors aside from gravity (and all relevant factors to that such as density) and time are excluded for the purpose of the calculation.
+Mandragara yea and IR are garbage in comparison so you would be cold but it would depend on the size of the hole if you boil or not
Finally after 12 years of school and my first year of University Physics class. I can see WHY he used these calculations and the science behind SHO's (simple harmonic oscillator's) however there's one thing I don't know for sure but I'm curious. Were the calculations at the end of the video, the ones with the complex stuff, were those using formulas for driven oscillator's?
Also, you can build a frictionless, straight-line tunnel between any two points on the surface and the travel time will always be the same. It doesn't need to go through the centre of the planet.

Can you please give me a brief explanation of how coriolis effect would affect the maths? (im mathematician dont know about physics). I think you are doing a really good job, this question have been in my mind for a long time, also with air we won't reach the other side and "bounce" until sating stable in the center? that wa my "answer" to the thougt. Thank you very much for the video
Has anyone solved the free fall through Earth problem starting at a point on the equator and curving to accommodate the coriolis effect? My sense is that it would be a bow-shaped curve passing thtough the Earth's center and emerging, not at the antipodes but a point offset by the rotation of the Earth during the elapsed time. A friend, however, has pointed out that an object could never reach the exact center in such a free fall due to the conservation of angular momentum.

Nope, everything he did was perfectly legit. Albeit, he took some mighty unrealistic assumptions to get to those points. However, it's an unrealistic question to begin with so it's all good.
+minutephysics, am I correct in figuring that this implies that neglecting air drag you could drop any object any distance from a point mass and regardless of distance the object will take the same time to reach the point mass?
The question was how long it would take to fall through earth
1 minute in he begins talking about shaving earth
So...approximately 38 minutes for me to get to China?
yes, and 30 if you've already jumped in the hole.
i better start digging that hole then
+John Smith lol
+John Smith its dug.. Not digged
fall through or around pretty much the same time and around has no digging
Loved this video! Please do more with actual physics calculations in it (the speed is fine because those of us that actually want to go through the math can just pause!) definitely my favorite of your videos just for that!
This was an awesome video!
Pro tip: make sure no one else jumps in the other side during your fall
If we were to include air and subsequently include terminal velocity in our maths, you would be unable to reach the other side. You'd reach the centre, then fall so far as to decrease your velocity from its terminal state to zero, at which point you then approach teh centre again. Eventually, you'd run out of momentum and be suspended at that central point, whereupon the intense heat would cook you inside out like a develled egg. Or a large turkey. Or basically any foodstuff that experiences such.
Mind shatter ... it's not possible to drill a hole through the earth from pole to pole since that would seperate the planet but gravity would simply pull the pieces together again ... not worth it ppl :/
+We-Play !-Play anything ! Also there is molten metal and stuff in the middle...
+We-Play !-Play anything ! no it wouldn't, it would just be like a weirdly-shaped doughnut, and they don't fall into two pieces :P the diagram in the video is 2D, so I can see where the confusion came from :)
+We-Play !-Play anything ! But it's not cutting the world in half, as it looks in the 2 dimensional drawing, it's merely a hole dug through the centre, like a doughnut. The world probably wouldn't collapse on the holes if it was only big enough for you body. Also this video was entirely theoretical.
+SbAsAlSe HONRe Ugghh thanks for the explanation I forgot to account for that ... but wouldn't the metal inside spill out ... or will it stay in place due to the forces cancelling out on it ?
Great Video!! You guys should do more videos with the math being worked out... It might not please everyone, but it certainly adds a lot more value to the content.

I love how this seemingly-difficult problem reduces to a spring
Ok good... Now in English
Trueeeee...Nice pic
Incase you weren't aware, the video is in English. Maybe you should pay attention next time instead of making a hilarious smartass comment.
***** wow you got me
i wonder what the flat earthers would say 😂😂
Dug two meters and now im in china
Lol yea
Char 11 😂😂
had the earth bee flat then as we'd have moved across the centre of the earth we'd have started to sort of bulge as we'd gradually move towards the other pole until our height would become extremely close to 0 (but not 0)

there is no such thing as a "hole"
Assuming you jump in that hole (like the video) standing up, when you get out from the bottom side, are you head up or head down?
Wait, would the speed you are traveling be enough to counteract the increasing gravity after you pass the center in order to get to the other side without going back down? If that was confusing, then, I'm pretty much asking would you be able to get to the other side without gravity pulling you back to the center? After all, once you pass the center, your speed will start to decrease. Would it reverse itself before you got to the end of the tunnel?
I'm a little late, but... Yes, it will be enough. Conservation of energy: you start on the given distance from the centre (surface) with no speed, and you end on the same distance with no speed, just on the other side. On the surface you have some potential energy. When falling, potential energy becomes kinetic energy (speed). At the centre of the Earth all of your potential energy became kinetic. Then you start slowing down, losing your kinetic energy, but gaining height, so gaining potential energy. The averall energy doesn't change so you will end up losing all the speed and gaining the same height as before you jumped.
due to heat and pressure you will come out on the other side as a liquid lol
There is no wall silly :*)
+rodri vp
No, the Coriolis effect is cancelled because you go from north to south.
Ofcourse not, you'll burn and turn into gas and carbon*. Btw you'll be slowed by air resistance so you won't make it to the other side.
I think we'd be under so much pressure and temperature that we'd turn into impure diamonds by the time we come out on the other side. Well that's my optimistic thought :D
+Prince_q8cool I mean if we're taking stuff like that into account you can probably assume that during your travels the two halves of the Earth will attract themselves together again and squish you, so I imagine that's a bigger problem
The math is melting my brain, I don't get it
What he said. A math equation is just a machine on paper. You follow a simple set of instructions and the machine does almost all of the work for you.

But would we orbit faster if falling toward the Western World?
All of this can be learned from an entry level physics class...
ROTMGHaunted
Don't remind me why I failed entry level physics...
ant billionz
No he didn't. These are all well known equations. I understood all the math and it was easy to follow.
Can you include a link to that spreadsheet shown in the video?
Can someone explain me where does the 4:00 equation comes from? I don't quite get it I mean I can't really figure it out I've been trying quite a bit to get to the formula my self but I'm not getting any close :c
That's pretty awesome. That would be a really cool trip to step into a hole, and step out on the other side of the Earth 38 minutes later. Just make sure you don't miss the stepping out part. And, I guess, don't touch the sides.
Also bring a air tank, and pretty heavy duty insulation, and a space suit. Otherwise you'll suffocate, melt from the heat, and die from the hard vacuum. Also maybe bring an audiobook because that would otherwise be a boring 38 minutes.
Jacob Siemons haha yeah, that too
I think its safe to assume the hole is self contained with impossibly resillient walls - this is a 'what if' you couldn't achieve in reality because a straight up hole would just instantly fill up with lava.
+elevown but the earth would also probably stick back together cause of the gravity I guess
Or... Perhaps a computer with civ IV: beyond the sword installed?
Fuck me that was maths
Correct me if I'm wrong but if u have one part of a body with equal density throughout and strait line from you through center to edges that the point closer tugs harder because it's distance SQUARED?
We need two air locks, a large drill, and piping that is basically immune to both heat and pressure. Also space suits with 40 minutes to 1 hour of air, and good magnets on each end that can be activated and deactivated at will.
If the piping exists, it can be done.
