Something like Thanos would do for Death, or Grandmaster would do because he lost a wager... The oldest light that has arrived to Earth so far is something like 14 billion years old. From recent Hubble observations, it's being estimated that there are 10 times more galaxies than was thought. That would mean a galaxy older than 14 billion has emitted light that hasn't made it to Earth so far, and there are plenty out there that fall into that classification. This goes for radio waves from an advanced alien civilization also, that would take even longer from the most distant galaxies (it takes years for it to just get outside it's own galaxy). Kind of creepy, isn't it? The whole concept of perceiving the universe as it was long ago, and that's all we have to go on, is very interesting to me. It only happens if the light got to you already. What happens way out there is of no consequence until then.
