01 / prediction

However, there was lots of ample theoretical reasons to believe that antimatter also would fall down. So they did this fantastic measurement, and they first they put in hydrogen, and they calculated that if they did this, something like eighty percent of the hydrogen atoms would fall through the bottom of the bottle, and twenty percent would go through the top just because gravity is very weak and the atoms will escape wherever they do, but there will be a bias pulling hydrogen atoms down.

Now, you could say, well, gee, that went from two hundred to a hundred, so it’s getting faster. But it’s also getting harder because the unification scale is of order ten to the fifteen, which—we can do the math.

So if there’s big clouds of gas, as the galaxies pass through one another, the clouds should interact, and the gas clouds should stop in the middle and be really, really hot. So then you would see, if there were no dark matter, you would see a cluster of galaxies, cluster of galaxies, a big gas cloud in the middle, and because the big gas cloud in the middle is much more massive than the galaxies themselves, you would expect to see distortions that we call dark matter distortions in the middle.

And the type of science I do now, people often ask, “Well, what good is knowing about how the inside of atoms work, how the inside of quarks work?” And I don’t know the answer to that but just being a little more pragmatic, if I go back, say, a hundred years, where people were trying to understand how the protons and neutrons inside atoms held together, how they split, how they– how you could combine them and so forth, this has led to nuclear power.

Then subsequently, it is hoped that at a higher energy, we will be able to blend the theory of everything together with all of the known subatomic forces, the strong, weak, and electromagnetic forces, and then gravity.
