but it does move around a lot. Energy can be potential (like a stretched-out rubber band waiting to snap) or kinetic (like the molecules that vibrate within any substance. And though we can't exactly see it, every time we cook dinner or shiver on a cold night, we know it's there. George Zaidan and Charles Morton get excited about energy.

As far as i know. Energy isn't really conserved in a universal scale. It only stays same until we include time dilation and warps into the picture. For example around the blackholes. The existence of singularity causes massive time and space warps. Infact beyond the event horizon time simply stops relative to the outside world. So any energy that goes in. Is pretty much lost. We simply don't know what happens to it

Didn't mention conversion into matter or from matter to kinetic energy in fission or (hopefully in the future) in fusion. Nevertheless this is a well put together and informative video which I would like to commend greatly for it's style.

Anyone please explain what is the reason for feeling cold. Feeling hot during the day can be understood as heat released by collision of more energetic air molecules with the skin. But what about the reason for feeling cold?

But of course there is that whole over expanding universe problem. The net energy stays the same but the space to have it in expands to a point where energy is too spread apart for life to exist as we know it.

I love this video. I watched robots have a seizure, the video suggest we blow up ourselves at our next cookout, thanos snapped that corn, and the other one was absolutely consumed

Does this simplified explanation not then lend itself to a notion of temperature not being possible without particles, vis a vis a true vacuum, even in regard to photons.

But cant energy be created from mass?
I thought that energy can never be created nor destroyed is proved false.
Mass and energy related by
E=mc2
