It brings me light to know that both are compatible. Because I can't count how many times I've heard "forget about Newton's laws in the quantum realm" and the such.

Interesting. I've always heard that you can't exactly combine quantum with classical, but it's good to know that they are tied together.

I know we can't use classical mechanics to describe or measure the quantum. That is not what I'm asking. I am asking whether particles still follow the same rules like action/reaction if there is a force involved. If electron A interacts with electron B, is Newton's 3rd law still being applied...

Well that is unfortunate then. I hope one day we will have clean, readily available energy then, because interstellar travel using antimatter seems very promising! Thanks again.

Hmm.. I see now. So basically antimatter in theory is 100% efficient. But at the stage we're at now, it would take more energy to produce and contain it than actually using its effects. I appreciate your insight!

That's almost ironic. Einstein saw what most humans didn't; he saw a universal secret that couldn't be observed externally. Simply genius!

That makes so much sense! I guess literally everything that exists is just compressed energy into a space. And it takes lots of energy to contain that energy in a small mass, therefore it takes lots of energy to release it. Wow!

Very interesting! Thank you, and everyone else for your insights!

Which also begs the question... Does this mean that annihilation is more efficient than fusion? Since in the fusion process, some of the mass is contained as a new element forms (say, hydrogen into helium), while of course the vast majority is emitted in photons and such? Could this also mean...

Oh my god, of course! I deserve a big fat facepalm. I guess it does have to do with how efficient the mass-energy conversion is. It still amazes me though that such a small amount of mass can produce ungodly amounts of energy. Really puts things into perspective. Like who knew a gram of...

No idea. But I just feel like there isn't enough mass to produce that much energy. Unless, it just depends on how efficient the energy transfer process is. Maybe the way TNT reacts and produces energy is a very lousy way which doesn't mirror its mass content, so there's tons of mass left behind...

If an object's energy is proportional to its mass, how can a gram of antimatter produce more energy than 80 kilotons of TNT? Where does all this energy come from such a small amount of mass?Skip to 5:19 of the video where he says this: Please explain this in the most simplest way possible.

Ahh, that's right. Disregard my last sentence then. Whoops!

Okay, so basically the answer to my original question on whether the space in between galaxies is expanding or the galaxies are simply moving apart, is relative? I understand dark energy is the precursor to all this, but in the end it makes no difference to what actually is being observed, since...

If general relativity is about "relativity", why can't you both combine space and time and split spacetime equally? I thought there is no "right way" in GR? The sun orbits the Earth just as the Earth orbits the sun. And you can (theoretically) switch spacetime into timespace when dealing with...
