I don't think that's the proper interaction between the electron and photon. By the same logic the electron can also emit photons.

I know that atoms break down into smaller particles through radioactive decay but do photons ever decay? Considering they have no mass leads me to think "no" but I do not have strong physics knowledge so was hoping someone could shed some photons on this question.

Of course Mordred. I am real glad I posted this as it really opened a new world for me.

Hello, I have read many posts where I find the above expression (Most notably from Mordred) but I only encounter it as part of explaining some other topic. Could you please expand on this with more information? It is a really interesting subject for me.

Hmmm how can we see the galaxies if they are receding at more than the speed of light? haven't these speeds always been constant? I understand that the universe is expanding at more than the speed of light so how can we see these galaxies? "a few minutes later" Put the keyboard down Strange haha sorry I just found the answer explained in a very nice manner. It perfectly explains all your points. Thank you!

Hmm I can make sense of that now. Thank you Bender. The way I read it first was colliding with my personal understanding of the speed of light (and gravity etc). I think of c as the speed limit of this Universe like a computer that has the limit of x frames per second and will never be able to support more than that.

Hello, I noticed a bad trend in science mass media where a information with factual basis is presented or a study made by qualified scientists and then comes the crazy media assumptions caused by a need to excite the uninterested public. I had such a case with the Uniform temperature of the Universe. I was trying to find a pertinent explanation for this but all I was able to find is gibberish. Can someone please explain the uniform temperature given the young state of the universe? (as I read and discount as gibberish is that the universe must have had expanded faster than the speed of light for this to happen).

Can you send me a picture of gravity?

Hello, I was wondering about something and was hoping to get some clarification. As I understand, the gluon is a mass-less particle and it always moves at the speed of light. But the gluons are also what hold together quarks in a proton. So how does it "always move at the speed of light" and is also part of a construct which contains particles with mass?

That is for sure not the definition of a black hole and I would not perceive a spec of dust as such. A black hole is actually doing the opposite of "reflecting and emitting light"

Why a black hole? How did we get back to the black hole again? What evidence doesn't?(Corrected) No one on this forum suggested that before the Big Bang there was nothing. "The model describes how the universe expanded from a very high density and high temperature state"

I thought from your analogy that the observable universe is the balloon itself.

I cannot deny the fact that I am entertained by your comments and I would up-vote you if this would be sci-fi literature section but sadly it is not. I am sure you have an ocean worth of knowledge above me but please try to separate rational thinking from fictional gumbo.

This is off-topic but you sound like a time traveler gathering info like Bruce Willis in 12 Monkeys. May I please ask what is it that triggered this post about the balloon/box space contraction?

I think physicists love to face evidence, especially if they believe in their findings. A discovery is useless if not put to the test and if other physicists are trying to disprove your research they end up validating it if it is correct.

The source of all Gravity is mass-energy. So is there any way to block the pull of gravity or modify it? (I know nothing proven yet but I would like to hear any theories if you guys know)

Thank you guys It's clear for me now. It's really fun asking questions on this forum. People like SwansonT, Strange (he's scary), Mordred and many more make it fun. You guys really adapt your answers to the level of understanding of the person who asks.

Yes I understand that but a Proton is made out of 3 quarks held by gluons so I will assume it's made out of quarks and gluons.

This will be very simple for most of you but please clarify something for me. A Proton/Neutron is composed of two up quarks and one down quark/one up quark and two down respectively and they are held in place by gluons. Protons/Neutrons are fermions but gluons are bosons. Can someone please clarify? Thank you.

Hello, A human visit/colony to Mars is arguably a future possibility but aside from the actual travel part, Mars presents a series of obstacles. Would introducing a potential carefully selected strain of microbes/bacteria be a good idea? If certain bacteria could survive in the harsh Mars environment could it improve the atmosphere over a long time period? Create greenhouse gasses? Also what are the potential dangers/cons of such an introduction.
