Not Possible is not an appropriate word to be used in this context.
After the invention of Aircrafts it seemed that flying at the speed of sound was impossible and that a sound barrier that limits the speed of the aircrafts was completed. But it was not so; Within a few years they found out that flight above that of the speed of sound was indeed possible.
Nuclear Fusion was thought to be impossible - it was accomplished - now carrying on with controlled nuclear fusion for energy needs.
Time travel is now a thing to wonder; But there are scientists and theories that could one day allow for timetravel.
Nothing is impossible if you put your mind to it.

Maybe survive being in the center of a hypernova explosion without any protective clothing, but you never know we might achieve that one day maybe in millions (or billions) of years time through intense genetic engineering provided we don't wipe ourselves out with global warming now and all future man made hazards we face.

Bringing back a life and fighting against nature. I guess these are the only things which cannot be done by man.
