If you said in your post that the wheel is made out of carbon nanotubes, the strongest material, you probably already knew that it was going to break.

finally, a soul!

Dude just hover over the link and you'll see it is a link to imgur. Unless of course you use internet explorer

...ANYONE?

if the universe is yours, then yes -you can

I was thinking about how astronauts aboard the ISS poop in zero g. I creatively had the idea of an axis on the ceiling of the toilet (I know there is no up or down, but you get my point). The stall would be manually spun by other astronauts (to save power) and the poop would naturally fall. That wouldn't be possible, obviously, because it would make the entire space station spin a little bit too. I was thinking if the bathroom could be temporarily detached from the space station. In that case it wouldn't transfer energy to the station. However that would be risky because there is a chance you'd fly away into space while pooping (that would actually be pretty funny, when you think about it. It gets funnier when you remember you're spinning as well. Well - nevermind ) Well, back on topic: Consider this hypothetical situation. If the toilet is free in space and spinning, would you have weight forever? Is energy lost? Also, a philosophical question: If there was nothing else in the universe but the bathroom stall, would it make sense to say that it is spinning? spinning in relation to what? Would you go weightless just because of the lack of reference?

Many of you must be familiar with polandball comics. Well, I decided to make particleball comics, where balls represent the subatomic particles of the standard model I've created two comics to get things going. Upquark is sad Tiny but heavy (it may be hard for some people to understand this one) what do you think?

For the same reason the gravity of planets and stars accumulate. They don't have to be touching one another. Each star has a small role in the whole gravity of the galaxy

I find this sad and hilarious at the same time

Instead of posting so many equations, can't you guys answer with a yes or no?

Intuition is like a brain fart

I have gathered some questions that have been bothering me for quite a good time.I hope you can ansswer them and help me out. An one paragraph long answer is good enough, no need to go so deep in each one. This can take some time but I hope you'll learn a lot too by answering it --- 1. What if there IS a center of the Universe? By analyzing the cosmic microwave background, we can see microwaves that got redshifted due to the expansion of space, right? And the CMB forms like a sphere around the observable Universe, I assume. If we travelled billions of ly to any direction, the waves coming from that direction would be less redshifted than the ones on the other side, right? So can we find the center of the Universe that way? 2. The inflation theory is a complement of the Big Bang theory added to describe the similar temperatures at opposite sides of the Universe. If the Universe was at a single point and it was in contact, why is a theory of inflation needed? 3. Why is the Universe so asymetric? It would make much more sense to say that all galaxies are identical and are at the same distance away from each other, right? 4. What if the whole observable Universe is actually the whole Universe? Howcan we know that there is more light coming? ---- That's it so far. I don't wanna flood you with questions. Thanks!

In order for gravitational information to flow, it requires space. Another universe wouldn't have space connecting itself with out universe, so I assumo gravity can't affect that other world

A possibility is that the two stars are orbiting very close to each other and the planet is much farther away from both, so its orbit could be pretty much stable

that makes sense. If you consider a single particle, the electromagnetic force will win
