If the universe is infinite, why isn't then the night sky just very bright of all the stars?

Two reasons:
1) There are plenty of stars that are just too far away to be visible in the night sky.

2) The universe might be infinite, but the observable universe definitely is not. Basically, since there is a maximum possible possible speed for any signal to travel (the speed of light), there are things that are so far away that signals from them haven't reached us yet (and maybe never will).

Not that I'm saying the universe is infinite. I don't know if it is. But infinite or not, we would observe the night sky as it is either way.

But....scientists managed to make neutrinos fly faster than light.

Yeah, no. It turns out that was probably due to a mechanical error. http://www.bbc.co.uk/news/science-environment-17139635

Not that it would make much of a difference. Signals take time to travel either way, so the observable universe is still bounded.

I think I also heard that scienticed managed to make radio waves travel faster than light..... :P

If something like that had happened and been confirmed, it'd have made as much news as the neutrino thing. So it sounds dubious.

Plus, radio waves are the same thing as light waves. They're both electromagnetic radiation. Saying that radio waves can travel faster than light makes about as much sense as saying light can travel faster than light.

Then maybe the light speed is measured wrong and in fact it is different. How do you measure something that fast anyway?

Eh, there are ways. Some of them involve taking advantage of specific properties of waves in general or electromagnetic waves in particular, some of them are the done the "hard way" by clocking how long it takes light to travel a long distance (typically an astronomical one). If you want to know, wiki has good explanations.

The bottom line is, there are many different ways of measuring and deriving from theory the speed of light, and they all agree. Radio waves don't move faster than light. As far as we know, nothing does, not even neutrinos.

As far as we know
.

Albert Einstein:
"There are two things that are infinite,
the first one is the universe
and the second one is the dumbness of humans
and I'm not even sure about the first one."

So you trust Einstein when he says that human stupidity is infinite, but you don't trust him when he says that nothing can move faster than light? Despite the fact the first one was a joking comment, and the second one is one of the most supported facts in physics, both theoretically and experimentally?


Odd.
