This was a screenshot I took months ago while watching a Geology Hub upload on YT. It was a lightbulb moment for my understanding of mass extinction events, (the largest was 250ma). I’ve referenced this multiple times, so thought I might share. Perhaps you find it as interesting as I do.

    You can absolutely breathe higher partial oxygen pressure unaided for a long time. Hyperoxia isn’t all that lethal and definitely not quickly, if you’re only visiting, there’s no problem.

    And if you want to live there, you should be much more worried about all the brand new diseases you don’t have immunity to, or the bugs that are bigger than you.

    The low oxygen is definitely a problem, especially if you need to run away from the stuff mentioned above.

      Yep. Dragon Gryphonflys that had around a foot / 30 cm wingspan, and underwater scorpions that were 18 feet / 6 meters long including the tail.

    I’m just stuck at how to calculate the Earth’s rotation with the current cosmic expansion; turns out, combining galactic rotations and universal expansions isn’t as simple as you’d think! After that I’m off towards time traveling.

      Problem with time travel is all the miscalculations trying to hit the thin skin of a moving object. Don’t forget the undulations through the galactic arms and the effect of the galactic medium against the heliopause. Good luck! Never know, maybe you’ll be the first above ground and non orbital. Bring a parachute, ablation shield, a shovel, and say hello to Hawking!

      P.S. If you get a chance, tell me to call in sick for work 2/26/14. I’d appreciate not being disabled in that alt timeline. Thx!

        A safer solution would be to just purposely target your arrival to the other side in empty space. While also travelling in a fully functional spaceship. Just make sure your little ship arrives within a set distance to Earth otherwise you will have to figure out how to travel millions of kilometers to get to where you’re going. If technology gets to the point of developing safe time travelling, I’ll assume that the same level of technology should be able to develop a space ship.

          Even easier, send fast-return probes to collect a hard record of locations. Who cares if your prediction models are to chaotic? We’ve already seen the destination!
