Do you really understand Einstein's General Theory of Relativity?

I mean, why objects when reaching the speed of light their space contracts and their time slows down to accomodate the fixed speed of light. It's all too confusing to me this time-space bending to accomodate fixed speed.

Anyone else finds it a bit hard to understand this almost century old theory?

what's funny is most people use it everyday.

time moves slower for gps sats and the clocks inside them have to adjust constantly or it throws the system coordinates out of wack by 6 miles daily.

Kind of. I am doing an Astronomy degree afterall. :cool:

I found this was a good, and relatively simple explanation of why this stuff happens.

Basically, (I'm not physicist so nobody get all mad at me) Light is always travveling at c regardless of how you look at it, even if you are moving or not, even if you travel at 50% c, you will still observe light to be going at c. The only explanation for this is time and space changing.

Light != Time. Regardless how education trying to brainwash me, I simply don't believe it. magicalclick

of course. Knowing these truth cannot really solve practicle problems. It is better to have imaginary time for convinience.

Can anything other than light travel at the speed of light?

don't move"close or at" speed of light. You don't need to move at speed of light to get those so-called, blah.

anything with mass or speed affects time but you can never really notice it since it is in the billionths or trillionths of a second range.

gps sats are one of the few things that you actually have to correct for.

airline pilots end up with like an extra billionth of a second per year.

and though it was really good explanation, I still don't quite get why is it when you're traveling at 99% the speed of light (C) and you launch another object at 99% C ahead of you, you'll see that object moving away from you at 99% the speed of light, yet an observer would see you moving at 99% C and the object you threw is at 99.9%?

Also, I'll gluon your bosomsxaos

GRAVITY affects speed of time as well. Time moves slower on the surface on earth then it does with a satilite in orbit.. Its so small though that you wouldn't notice it, but something like a gps would be thrown off in time.

Familiar with it.

Yes, what it said. It was a p. simple equation which is why immediately the realized implications of it of made me realize that everything I had ever known up until that point was a lie. (sort of)

I know that at lightspeed, everything slows down for you. I know that if you had a train traveling at lightspeed, then time would move much slower in the train and that when it finally stopped, the world outside would be incredibly different and older. Something like that, I love physics, but its hard to remember the exact math behind it when I've just had a few.

I mean, why objects when reaching the speed of light their space contracts and their time slows down to accomodate the fixed speed of light. It's all too confusing to me this time-space bending to accomodate fixed speed.

i dont know but i have my own theory, that the speed of mind is faster than light, the brain can go faster than light by one thought, "tries it" i just went 4 trillion billion zillion miles away and im sure the speed of light didnt get there yet........thoughts? by the way its a serious theory so anyone here want to try and debunk itcee1gee

I feel bad for anyone who tries, because even though it is serious it can't be taken seriously.

It's a very complicated mathematical theory so no I don't think I understand it at all. I'm a complete failure in mathematics. You need to master Riemannian/differential geometry quite well in order for you to understand it deeply.

There is another very complicated mathematical theory called Quantum Field Theory which I also don't understand. Both of these theories when combined together lead to an even more complicated mathematical theories called Quantum Gravity theories, String Theory being one of them. But then again you need to be very strong and talented in mathematical ability in order to understand Superstring Theory, Loop quantum gravity etc...
