INSIGHT

Seeing Stars in the Past

  • Light from stars takes time to reach us, so we see stars as they were in the past, not as they are now.
  • However, because stars live billions of years, most stars we see still exist when we observe them.

Limits of Observing the Big Bang

  • The universe is expanding and we cannot see the Big Bang directly, only its afterglow due to an opaque barrier to light.
  • Gravitational waves might allow us to see earlier times beyond the light barrier.
