i hear a lot of people around me telling
that it wasnt einstein inventing relativity,
but some other guys before him

exactly what was einsteins contributon
to relativity, did he stole his tensors?

- For general relativity: see pmb's reply.

- In case you meant special relativity (do you know the difference?): that
was the outcome of the work of several people and originally it was known as
"the theory of Einstein and Lorentz". Some important contributions by
Einstein: he derived the Lorentz transformation equations directly from the
principle of relativity and he pointed out that time dilation can be
measured as a physical phenomenon.

But note: It's obvious that you're a troll. I only replied because some
others replied and therewith gave value to this thread.
