Reply to comment by NotAHamsterAtAll in The Fermi Paradox and the Possibility of Intelligent Extraterrestrial Life by Beginning-Court1946

travelling at or near lightspeed isn't necessary as a component of the Fermi Paradox so not being able to travel at those speeds can't be a solution to it.

It is assumed that:

  1. It is possible to travel for thousands of years in space, which might be impossible, even for machines.

  2. It is assumed there is anyone even wants to do it, when there might be no point in doing it.

But I personally think the great filter and rare earth hypothesis are enough. Us being alone in the Milky Way is absolutely possible. Us being alone in the universe is possible, but irrelevant, we will never be able to do any meaningful interaction with any extra-galactic civilizations.
