Relativity?

[lionhead]

What does the word relative actually mean? I mean, if its just about what a human being can know through his 5 senses its not a really good example.


Einsteins theory of relativity. Is that just about the deception of the eyes about time? what is this? Fantasy? Fiction? is it about anything at all, does it proof anything? i don't get it.

I would really like to know what this light speed thing came from, What is time travel? is that just saying that your eyes see something else then it actually is or is it more physical? or relative?

relativity

n : (physics) the theory that space and time are relative concepts rather than absolute concepts [syn: theory of relativity, relativity theory, Einstein's theory of relativity]

[Hitchhiker]

One could determine that space-time is absolute if one was an objective observer. One's own involvement in the universe introduces bias that makes it a subjective experience.

Memories are another example of things that are relative. The police officer may think the light was red; the driver may think it was green. Without an objective medium, such as a camera recording of the event, to determine which one actually occurred, it is a relative experience.

[webtaz99]

Einstein's theory of relativity broke from the current Newtonian physics because Newton assumed a single "frame of reference", while Einstein postulated multiple ones, making the differences between them "relative".

Also, time dilation doesn't "fool the eyes". It exists as a measurable phenomenon.
