Which theory explains the origin of life?

RNA World has been the prevailing theory for the origin of life since the 1980s. The emergence of a self-replicating catalytic molecule accounts for signature capabilities of living systems, but it doesn’t explain how the protobiological molecule itself arose.

What can destroy a galaxy?

Black holes might kill entire galaxies with blazing energy,dooming embryonic stars before they can get born and condemning the remainingstars to a slow death, scientists have found.

How can the universe end?

If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.

How does the universe exist?

Krauss claims that our universe arose naturally and inevitably from the operation of gravity on the quantum vacuum, empty space teeming with virtual particles that spontaneously pop into existence before disappearing again.
