you are energy. energy cannot be created or destroyed.

The sun has no nuclear whatsoever it's electric like an arc welder

Excellent explanation. Well done

Simple explanation we are talking about our souls

I can’t wait to try it 🫧

So clear! So awesome! Other videos left me confused! Now I get it! Thanks so much!

Wind resistance not speed of light right?

thanks i get answer

Sir I am Indian and 12th class but I understand ur language and all concepts one by one and I am don't understand any other english movie study etc 😊

I think there's an obvious question not being asked. What is the universal definition of "Created" and "Destroyed" we're using here for the Law of Conservation of Energy? For example, let's assume there are multiple universes out there or that it's possible to leave this universe. If it were possible and I decided to leave this universe, is the matter and energy that I'm made up of now technically "destroyed"? It no longer exists in this universe. If I step back into the universe and bring a rock(or whatever) from outside the universe, is matter then being created by me because matter that never existed in this universe now does? I'm pretty certain there's nothing that says our universe's rule sets apply anywhere but our universe. So explain how matter or energy is not being "created" or "destroyed" in this instance? It's a thought experiment. I don't expect a "right answer". Nor am I sure that leaving this universe or there being multiple universes is even a thing. If the law of conservation of energy is an actual rule of this universe, would it prevent us or anything from leaving or coming in?

I had already learned this in a class last year but I needed a refresher badly and this did the trick. The explanations for each step were very clear 👍

What makes us a closed system though? Aren't we a part of the grand cosmos and beyond? Isn't all energy connected? Yeah feel that one out..

maybe..but how did E know that energy released from mass required the mass to be multiplied by the speed of light squared?

why is gravity always depicted as a flat sheet with objects pushing down on it? gravity has to be three dimensional. there are no sheets that objects press on. having said that I appreciate your clear description of relativity, the best I have found so far.

Can you please explain how a reactor that uses energy to achieve e=mc2 nets MORE energy than that needed to accelerate a mass to the speed of light?

Very well done! Now I FINALLY understand e=mc2 (beyond the obvious formula) and it's impact on physics and technology. Thank you!!

How dare you say it will help the poor!! The poor don't need that amount of electricity!!! They just need a safe planet to love their children, their families, their friends.. their community.. their country.. the world.. and the universe ✨️ 🙏 nuclear power was never nessersery!!! We can generate electricity so simply without the need for any gracious projects just to fund those who have been educated in nuclear fusion.. we have to stop educating too many humans with jobs that aren't needed.. in order to prevent them from wanting money from unneeded endeavours.

That was very clear, and its 58 years since was last in a school , Thanks 😊

Very interesting, if dark matter cant be found, then perhaps the "Steady state" theory of the origins of the universe may be accepted as correct after all 😊

Excellent (my garage follows this rule 😊) as well .👍

I knew everything in the video. I want to know what the number (7.07) means in the data if we are not comparing. No value was off by 7.07.

Thank you. Thumb's upped it. Just curious, how is this so useful, couldn't someone just kind of look at those numbers and see they are more spread out? Thank you!

So in theory a time chamber be made

I get it now. Thank you! this video is clear and straight forward. It is a good idea to add to it what is meant by a small and large SD compared to the mean. I understand that an SD less than 10-15% of the mean is often considered small, while greater than 25-30% of the mean is considered large. A small SD compared to the mean indicates the data tends to cluster around the mean (measure of central tendency), while a large SD compared to the mean means the data is more dispersed away from the mean.

Thank you so much for such a clear explanation

Thank you for explaining why they get squared! Best video on this topic

Thank you really helpful video!

👍👏

Energy can never be exchanged.

very clear thanks for this explanation

cool . like your delivery 😁

This is the most simple understansable explanation i've heard ..thanks 😊...

so it can be created and destroyed we are just in a large prison... now who created the system? yes. that's who.

It is a description, not an explanation!

And superposition 🤔

Where do the thermal and light energy from a wood fire go after the fire is extinguished? Where does the energy from a full tank of gasoline go when you've run the engine long enough to empty the tank? That energy I got from eating a Snickers candy bar in 1988; where is it now? It's funny that something that "can not be created or destroyed" has to be constantly produced (which, in common-speak, means the same thing as "created") because if you stop producing it, it's gone (which, in common-speak, means the same thing as "destroyed"). For example, stop burning e.g., wood, coal, oil, gas in your house during the winter and your house is going to get very cold, because that heat energy will soon be gone from your house. And if you use, e.g., candles for light, when you stop producing light because the candles have been fully consumed, your house goes dark because that light energy is gone.

Deuterium - not Deutirium

Hi Craig that is a very succinct and clear explanation. Thank you for your effort. When attending a chocka full Uni class where you just have to keep up with the pace- regardless, something is bound not to gel at the time. It’s great to have a simple explanation to do in your own time. Taking it to basic level as compared to a person with a phd , who for them this is probably rather basic… their ability just to keep it straight forward can sometimes not transpose… and you can get stumped and stuck. Your report card shows you have good potential 😊

-10^2=-100

What does it look like in the core of a star? The middle point.

yes...this is because we exist in a bubble...there are 2 things outside the bubble....1. pre big bang. 2. Post Big Bang. We dont know anything about either of those...but we have to answer the question....Was the Big Bang an explosion? If so, all explosions in our bubble are Created....so based on what we know...the big bang was created by something.

Some in the comment said, the fact that energy is present means it had a beginning. Not necessarily because the one who suppliers that energy doesn't have a beginning or an end. Quite possibly energy is not the only thing like that.

👏👏👏

Good

open system better

You misspelled configuration.

I HATE THE FUTURE AND ALL I CARE ABOUT IS THE PAST AND ONLY THE PAST FOREVER AND EVER AND FOR THE REST OF MY LIFE

Never found alone.. in other words, my imaginary friend

Indeed, your Lord is Allāh, who created the heavens and earth in six days and then established Himself above the Throne.1 He covers the night with the day, [another night] chasing it rapidly; and [He created] the sun, the moon, and the stars, subjected by His command. Unquestionably, His is the creation and the command; blessed is Allāh, Lord of the worlds. Translation interpretation 7:54 quran
