Giant Sheets of Dark Matter Detected (the largest structures in the Universe)
- TheTarquin 19y agoOkay, now THAT is mind-blowing. I can't even wrap my mind around some of the distances in our own solar system, much less something 270 million light years across. Maybe I wasn't cut out to be an astrophysicist?
- whacked_new 19y agoSuch distances are beyond intuition, but I doubt it's something you can't do. You can just imagine yourself walking to a park, just really far away, and you travel really fast. Speaking of which, many people use this "pea in a football field" analogy when talking about electron orbits, but I'm guessing that few if any people can actually visualize such a thing.
- TheTarquin 19y agoI hadn't heard the "pea in a football field" one. As a former marching band geek who knows well how big a football field is, that definitely helps get some perspective.
- D_T 19y agoI am surprised this did not receive more points or interest. Who isn't interested in the upper and lower bounds/limits of our universe?
