It must be nice to be so brilliant that you can label as "clearly

It has been clear to such respected scientists as Arthur C. Clarke and Albert
Einstein that time travel is impossible.

And they might be right. Probably are right. But it would be a mistake
to use the word "impossible".

An interesting idea I've heard is that time travel is possible, within
the laws of nature. But every time some species invented it, they
changed the past and broke their own invention. This continued until
the Universe stabilized in a configuration where no species ever
invents time travel. Not that it couldn't be done, simply that it
wasn't/isn't/won't be.
