Party physics Memes

The smugness is astronomical here! That feeling when you're at a party and someone mentions traveling "back in time" to a star that's "5 light years away." You stand there, drink in hand, silently judging their physics fail while everyone else nods along. For the uninitiated: a light year is indeed the distance light travels in one year (about 5.9 trillion miles), not a measurement of time. It's like saying you'll travel "5 kilometers into the future" – technically incorrect, but impressive at parties.
