Today it was announced that antimatter falls down.

That might sound trivial, but it is an interesting an important result in our understanding of particle physics and the laws of nature.

Everything that we see around us, and most of what we see in space, is formed of matter. However just over ninety years ago, physicists discovered that every known type of matter particle in nature is paired with another type of particle, known as antimatter.

Sometimes it amazes me how quickly science advances.

Just over thirty years ago there were no known exoplanets, and some astrophysicists were even speculating on whether they ever would be detected. Then in the early 1990s, multiple teams of astronomers were able to detect the periodic dimming of distant stars, and later the Doppler shift in the light from other stars, and from that data they were able to conclusively prove the existence of exoplanets.

These are the years when one has little or no income, but must bear the expenses of living independently for the first time.
