can anyone give me some good explanations or experiments about time and the speed of light. my knowledge at this point is kind of limited. I know the concept but can someone explain how its proven in theory or experiment.
thanks

There is more stuff on the internet about this than you can shake a stick at. Surely you can do some research on your own and then come back with specific questions if there are things you don't understand?
 
There are loads and loads of good physics books which explain it as part of an explanation of something else =)
I recommend Max Born's Einstein's General Theory of Relativity, the whole first half of it explains these kinds of questions, even where the fundmental ideas about mass, force, movement etc. comes from and he explains some experiments and problems about calculating the speed of light. Have fun reading it if you do =)
 
i have been researching it online. but i can't seem to find anything more than what i generally read. I am curious. if getting closer to the speed of like makes time slow down, could you go back in time if you could go faster than the speed of light. is that possible to make an object go that fast? and what could possibly happen? or is this some left field idea that don't matter.

Please search the Special Relativity forums. You should find lots of threads of interest.

Thread 'Can this experiment break Lorentz symmetry?'

1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...

Thread 'Relativator (Circular Slide-Rule): Simulated with Desmos - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...

Thread 'A sufficient condition for integrability of equation ##\nabla g=0##'

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
