Can someone answer this last question (in bold)?

Thanks! It has been very helpfull! I understand most of the things you said, except I know have a few new questions: -If we are simply "coasting along on the push we got at the beginning", shouldn't it be a space to support the expansion? Doesn't that need to be created? I mean, don't things...

I know nothing about astronomy, (but I find it very interesting) so, here it goes: 1-If you look at the sky, is there an exact location of the Big Bang? If so, where should one look at? Or is the BB more like space being created between the planets? -If the first one, Shouldn't that place of...

I may missing hundreds of things here, but I don't think that I'm missing that. I never said that the light reached to the corner of the square that I've drawn. In fact, you can see that I've made in both drawings a circunference that goes from the horizontal vector to the vertical in order to...

Thanks man, I do get that in order to make the formula work the line should extend to infinity (I even put that next to the last drawing in the first page), but if you see what's next you'll see my problem. And it is this: If the light beam takes one second to reach the mirror, and the...

-JesseM, sorry, I think that I have confused you with my drawings. I do get that the speed of light is measured the same in both frames. -Doc Al: Sorry, I reckon that I do explained things that you already know, but it's because I may have them wrong that I put them there. As much as I would...

Thanks for the patience. -I'm dumb as a rock, but... light doesn't have mass and it travels at c, how can it be that one can't measure it's SR properties? I'm trying to imagine light from it's POV. I know that it doesn't have eyes (nor does a ladder and yet we say that it can enter inside a...

but if I were to apply this formula using the speed of light as the velocity wouldn't it give 0 on the bottom? I mean, wouldn't "v" = "c", so both square numbers on the lower right would cancel each other and end up as 1, therefore giving the square root of 1-1. That would lead to dividing by...

time dilation limit? (how much does time dilate at "c") Hi, this is my first post here. I'm sort of an amateur. Here's my question: I was concerned about the idea, many times suggested, that if you were to travel -and I know that it's impossible- at the speed of light, you would see that...
