OK, so let me see if I got this right. Given our current understanding of the universe is correct, a viewer outside our universe and looking at it as a whole as if it it were a balloon, gravity would appear to travel faster than light. From our relative position it would appear to travel no...

I know the general premise is that the "speed of gravity" is equal to that of light speed, but something that doesn't quite make sense to me is this; Space itself can, and does expand faster than the speed of light right? By proxy it should be able to contract faster than the speed of...

Ah, ok that makes proper sense to me. I felt like it should slow down over time but couldn't figure out why, but it's the tension of the balloon itself. That makes sense now, thank you for helping my head pass it's brain fart :)

Trying to wrap my head around this thought experiment and I was hoping to get some expert advice on this: Take a balloon made out of a rubber that can stretch infinitely thin without breaking blown up to normal balloon size. Next put it in an infinitely large, perfect vacuum and let it go...

You have to deal with the classical stuff and fully grasp it first from what I have seen. Without understanding the fundamental laws in physics and how to apply them properly along with the terminology associated with each you won't be able to grasp quantum mechanics or relativity. You...

Wouldn't a simple description of information be like this: "Information is anything that can be used to help find the cause to an effect"? ex. effect: a neutrino hits a detector cause: a star went supernova information: any form of data that could possibly be collected from...

Yeah, seemed that since the OP was only wanting stuff in a basic form since he was wanting it all in a perfectly straight vector, hence why I went with the Newton style rather than the GR/SR versions.

Should just be simple addition. Two people are playing catch on a train that is going 75 km/h. The two people on the train see the ball as going 50 km/h, so relative to the two people on the train, the ball is going 50 km/h. To a viewer on the ground, the ball is going 125 km/h. The...

Correct me if I am wrong here as I probably am. But, once an object of pure energy and no mass, e.g. a photon, has been created, it will be moving at C no matter the amount of energy put into the creation of said photon. No matter if it's the entire universe converted to energy or a single...

What? The official name isn't "The Big Bang Theory" it is "The Big Bang Theory for the Origin of the Universe" http://www.rsc.org/chemsoc/timeline/pages/1927.html Here is a bit from NASA: "The Big Bang Model is a broadly accepted theory for the origin and evolution of our...

From what I have read it would seem that the current big bang model is the Newtonian gravity of our time. It does a great job of explaining what can be observed but still has some flaws in it's origin just like Newton's gravity. The theory works, and until we have a better understanding of...

Hey all, I'm quite confused on this and am curious to be put straight. Now I understand the basic principles of relativity, this one just bugs me. Now I have always been taught that the famous E=MC^2 formula was proof that mass would reach toward infinity as it neared the speed of light...

That doesn't make sense though. A particle with a higher velocity has more energy. You must add energy to an object to get it to speed up and the object then gains that energy. This is why all the matter in the universe isn't enough to get an object with mass to actually reach the speed of...

The shell is a neat idea, and if I may chime in on it a bit at a different angle possibly. Since, as an object approaches the speed of light it gets more massive, the stream of atoms and subatomic particles stream toward the singularity, they will eventually reach a point where their mass...
