Hello fellow galactic travelers, welcome to the thread dedicated to the very large (as well as the very small). The universe is a fascinating place that’s, for all intents and purposes, too unfathomably large for our feeble human brains to comprehend; but that doesn’t mean we shouldn’t try, right?
I’ve always been fascinated with the wonders of the great beyond. Being from a very small town in Michigan, with my house in the middle of nowhere, no less, I’ve been granted the delightful opportunity to gaze upon the stars in all their majesty with little obstruction. And only recently have I delved into the incredibly small (I changed my major from mechanical to materials science engineering last year).
The insane complexity of it all is quite mind-boggling. And though I’m not at all a religious person, it’s hard to believe that this all happened randomly (but please don’t turn this to a religious thread in any sort of way). Of course, my favorite idea is that before anything existed (pre-Big Bang), there weren’t any sort of laws of physics that stated that something couldn’t just start happening.
Let’s start with some fun facts:
-The Earth is spinning at 465.1 m/s (1,040.4 mph)
-The Earth is orbiting around the sun at 29,800 m/s (66,660.7 mph)
-Our solar system is is orbiting around the center of the Milky Way galaxy at 220,000 m/s (492,126 mph)
-Besides all that craziness, the Milky Way itself (along with us) is hurtling through space at the break-neck speed of 515,000 miles per hour due to the expansion of the universe.
Ok, so we’re going pretty fast (HOLD ON TO SOMETHING!).
Would all this speed cause a problem with time machines? Unless the entire system of the time machine and Earth with it’s blazing-fast velocity act as a non-inertial reference frame, then you’d be simply transported to a point in the middle of space, and consequently die.
Please, PLEASE share any information you have or any questions you have! I’ll be updating this thread periodically with tidbits of info I have on space, planets, black holes, stars, and the stuff that makes all of it up - atoms.
