Travel to Andromeda? And back?

[amateurbob]

My favorite episode he is on is when he talks about the moon Titan orbiting Saturn, he points out that when the sun starts expanding towards the end of its life, it will warm up Saturn and Titan, and Titan will be in the " life zone" for billions of years, potentially being a place to hang out until the end of the solar system. Get your tickets now.

Like at a restaurant?

Why would this relationship between energy and matter prohibit travel outside the solar system?

As has already been pointed out - we have two space craft, built in the 1970s, that have already traveled outside the solar system.

The same as rocket engines can't work in space because there is no oxygen.

I thought it was because they had nothing to push against.

Regarding having no oxygen, perhaps they could carry their fuel with them ... hey, wait.
