Ever watch a whirlpool? How about water going down a drain or even a Nafo North Atlantic Fella Organization Long Sleeve T Shirt of cream swirled into your coffee? It sometimes looks like a spiral galaxy. And we once thought gravity was holding a galaxy together. If you watch a whirlpool carefully you will notice the outside orbits the center slowly and the closer to the middle you are the faster it spins. But this was a bit of a problem for galaxies because this would make the arms of the galaxy wind up tight. They would not last for millions of years. Earlier in the century, before computers, astronomer would hire dozens of women who were good at math to do calculations for them. One of them made an important discovery: the speed of the stars in the outer arms was way faster than it should be. The galaxy was spinning like a solid LP record album! According to the laws of gravity, which we know quite well, it shouldn’t behave like this…unless there was WAY more mass than we could see. And the issue of *dark matter* was born. Yes, there would be a lot of dust and gas and planets and small stars we couldn’t see. But all that is still not enough for the behavior we observe. It is a mystery we are still working on!

If you go straight from Tulane Green Wave 2023 American Athletic Conference Champions shirt just wear your work clothes so you don’t seem fussy. Otherwise, it depends on what you normally wear to work, and the venue. If you wear a suit and tie to work, but the party is at a casual bar or restaurant (a place where on a normal night people would wear jeans) then dress down and wear jeans and a sweater with clean sneakers or leather dress shoes. if you have a casual work place where you wear jeans or a work uniform and the party is at a nicer venue specifically for parties (like a banquet hall) or a nicer bar/restaurant then dress up and wear slacks, a sweater and dress shoes. If you are really really unsure, ask your colleagues what they are wearing. If everyone is unsure wear clean dark black jeans (these could look like dress pants in the dark) a sweater and dress shoes. This outfit would fit in anywhere. In NYC just wear all black and you’ll look chic and appropriate.
