Looks negative

How? Have you ever free dived? How far can you make it before the pressure breaks an ear drum?

You said two things. Earth is hallow and we live inside the hallow area. So if we lived in a cave what is space? Literally you can look up and see we are not in a cave we’re floating around something. Second we’ve dug as deeply as can be reached and there’s always more dirt/stone. We’ve take what would be equivalent to an X-ray of the earth. By sending radio waves through the earth to different points we can measure the thickness of the earth. This is how they estimate time for a volcano to erupt by detecting when magma chambers are filling. You can also measure the volume of earth and compare it’s motion and gravitational effects to see if they equal out. Lots of ways to prove it

Bots never heard of an emergency fund

If you’re gonna do that why not rolling cds? You’ll lock in 4% for many years after the cuts start

This is true in general. There are a few places around the world that are approaching day zero of water supply. It’s a solvable problem but needs more focus

It does have some dangers to it but if aliens are intelligent enough to travel to other stars to steal water they could probably make it

There is a ton of water just under the crust of earth. I think we we would dig for that first.

It feels nice because it looks nice

How would you stop?

For the person traveling wouldn’t their time move much slower if we could get to 90% the speed of light? Exploration might be possible but it’s a one way mission where you’ll never see earth again

Even then you probably can’t get out of the Milky Way

Why didn’t you roll forward
