Well, I know I couldn't have put those sentences together, so you've got me beat!

I can understand not eating, but what about drinking?
How do they not dehydrate just from breathing?

Reply to comment by CloverArms in How many years do you think we have until space travel? Something like cowboy bebop by Aware_Ad2047
SpaceX's Starship is about to change all that. The shuttle cost billions per launch, and current (manned) rockets cost hundreds of millions.
Starship will cost an order of magnitude less per launch, and with it's 10x capacity of existing launch vehicles, the cost per kg is another order of magnitude cheaper.
This "cheap" access to space will result in the next leap in human advancement. So much new/renewed focus on new problems to solve, which'll result in new technologies, new inventions, new advancements.
The next 5 years are needed for this new paradigm to mature and become a "commodity" (just like the passenger jet era of aviation) but, from there, the "explosion" will begin.
The 2030's will be an amazing and exciting time to be alive. And, on a slightly different tangent, I can't wait to see what the Clipper and Juice missions learn about Europa, Cassini, and Ganymede (Jupiter), and what Dragonfly learns about Titan (Saturn). Hopefully we'll have something in the works for Enceladus (Saturn) soon, too!
Exciting times ahead!

Reply to Is time travel going to happen yes or no? by MixOk1458
Time travel to the future is easily possible. We don't have the ability yet, but will soon enough. However, there's no going back in time.
You can travel to the future by jumping in a space ship and going somewhere very, very fast. The closer to the speed of light you go, the faster thru time you will travel. Depending on how far and fast you go before returning to earth, is how much time will have passed here, compared to you.
A few months for you could be decades or centuries here on Earth.

Fascinating. I've never thought of it this way. Thanks for sharing.

No need for observation to make that assessment.

Holy crap that was an excellent post. Thanks for sharing.
I wish I had gold, but you'll have to settle for my upvote instead.

No. That's (low) orbital velocity. Escape velocity is actually much higher than that.

Reply to Time dilation question by [deleted]
OP, I think you'll appreciate this video by Dr Kipping (Cool Worlds channel on YouTube) that discusses time dilation via space travel.
Lots of very cool stuff in there to ponder! And his whole channel is a big rabbit hole. A gravity well so deep, you might even call it a black hole. 😏
