   The new theory about 'Oumuamua is simple and plausible. In interstellar space, water ice breaks down into hydrogen gas. When the comet approached the Sun, pockets of trapped gas escaped and gave it a nudge.
   I'm not saying it's not aliens...but it's almost certainly not aliens.

     This is the most convincing explanation I've seen for 'Oumuamua, the interstellar object that accelerated strangely as it flew away from the Sun.
     Most likely it was pushed by puffs of invisible hydrogen gas. Sorry -- not aliens! https://news.berkeley.edu/2023/03/22/surprisingly-simple-explanation-for-alien-comet-oumuamuas-weird-orbit/ #comet #interstellar
