this stuff is just embarrassing... let it go...

Travel to a nearby star system will take 25,000 years.
By the time you get there, you will have been dead for >24,900 of those years...

@JollyR travel distances can be arbitrarily shortened by increased speed

If you're going 0.999c a cold neutral hydrogen atom will hit you at 0.999c. A speck of dust is like a nuke going off.

99% of your spacecraft will have to be shielding. And the other 99% will need to be fuel, to accelerate all that mess.

However, your journey becomes a pleasant drive through the countryside. But the earth you left will be different when you get back...

Heard of the Orion spaceship that was never built? Used nukes and a push plate

What's the plate made of?

Super duper metal (idk, probably some kind of ceramic)

Cobalt-thorium-G.
