But in the past 10 years, we were able to measure the mass of the galaxies and discovered they shouldn't exist. The stars in them should be getting flung into the void because there's not enough mass for gravity to hold them together. The missing mass that we still can't see or detect is being called "dark matter" for now. And we discovered something is pushing our universe apart so it's actually speeding up as it expands. We can't figure out what's causing it, so we call it "dark energy" for now.
I have a friend, probably the smartest guy I know. Valedictorian, PHD from UCLA in astrophysics. I ask him about this stuff all the time and despite working in the field even he says it is hard to keep up.
With the rate of technology gain we have had even in the last 50 years, I can only guess as to what the world of science will look like 50 years from now. Sometimes I wonder if it isn't better not knowing.
Anywho... to Cinorjer's point. It makes me think of one of those scenes from the end of the "Men in Black" movies where the aliens are playing marbles with galaxies. haha
