The speed of light is independent of the source or the observer.
The length, time and mass depend on the circumstances under which these are measured. Moving clocks run slow. The length of a moving rod contracts. The mass of a moving object increases. But all these happen perceptibly only when the speed of the object is comparable with the speed of light. Otherwise, these relativistic effects are negligible and Newton's Classical mechanics holds and is a special case of the relativistic mechanics of Einstein.

Energy and mass are different aspects of the same phenomena and can be converted one way or the other via Einstein's famous equation.
The speed of light is constant, in a given media, regardless of the inertial frame of reference of the observer. The implications of this are space-time dilation and mass inflation as an observer's speed increases and approaches the speed of light.

well well what in the world is not relative? if for example i say that while i type this sentence my fingers are moving with respect to the stationary keyboard but how would you say the keyboard is stationary? you could either say it is stationary w.r.t the surface of the earth which is in fact moving w.r.t say the sun and so on.or you could choose the easier and more practical path and saythat it is stationary w.r.t the moving fingers and the fingers and the keyboard would become a self satisfactory system defined in itself .
so maybe i could conclude by saying that absolutely defining a system is not practically possible and we could identify a small part of the system or a differential element and try our best to define it according to its constituent elements ; a further extension of reductionism.
the best part of any theory is the universality of its application and the only limit to the expansion of the theory of relativity is one's imagination.

"Explain the theory of relativity in your own way?"
The mathematical studies of the space-time continuum, where space (3 dimensional) and time (as the 4th dimension) are combined for theoretical investigation, with regard to motion and viewpoints therein.

Yeah well.... there is a train, and a light bulb, and someone inside and someone else outside and when that train goes really fast the person outside sees something different and because of that when you go with the speed of light time stops and your weight becomes immensely huge, like inifinite, and well that about wraps it up

The speed of light is always the same in any given reference frame of observation. Time and distance dilate to maintain adherence to this rule even if the reference frame itself approaches the speed of light.

Say you woke up one day and your bed was gone. Your room, too. Gone. It's all gone. You wake up in an inky void. Not even a star. Okay, yes, it's a dumb idea, but just go with it. Now say you want to know if you move or not. Are you held fast in one spot? Or do you, say, list off to the left some? What I want to ask you is: Can you find out? Hell no. You can see that, sure. You don't need me to tell you. To move, you have to move to or away from ... well, from what? You'd have to say that you don't even get to use a word like "move" when you are the only body in that void. Sure. Okay.
Now, let's add the bed back. Your bed is with you in the void. But not for long -- it goes away from you. You don't have any way to get it back, so you just let it go. But so now we have a body in the void with you. So does the bed move, or do you move? Or both? Well, you can see as well as I that it can go any way you like. Flip a coin. Who's to say? It's best to just say that you move away from the bed, and that the bed goes away from you. No one can say who's held fast and who isn't.
Now, if I took the bed back but gave you the sun -- just you and the sun in the void, now -- I'll bet you'd say that the sun is so big, next to you, that odds are you move and not the sun. It's easy to move a body like ours, and not so easy to kick a sun to and fro. But that isn't the way to see it. Just like with the bed, no one can say who's held fast.
In a word, you can't find any one true "at rest". You can't tell if you move or are at rest at any time. You can say that you go and all else is at rest, or you can say that you are at rest and all else goes. It all adds up the same both ways.
