What were the fantastic 4 exposed to that made them have powers?

Answer 1

They went up into space to run some tests on a cosmic storm that could have sparked life on Earth, and the storm sped up and came early, catching them by surprise. They all lived, but their powers didn't appear until later, while they were at the hospital. Ironically, their powers perfectly fitted their personalities.
