10 Scientific Phenomena To Be Thankful For, Today And Every Day
“2.) Be thankful for an asymmetric Universe. There are all sorts of important symmetries, but if everything were completely symmetric, there would have been perfectly equal amounts of matter and antimatter. As the Universe cooled and expanded, they would have annihilated away almost completely, leaving just a sparse set of particles and antiparticles less than one-billionth as dense as the Universe today. But instead, we have a Universe filled with matter and not antimatter, and that makes all the difference. How that asymmetry came to be is still a mystery, albeit one with many possible outcomes. Nevertheless, that the Universe is asymmetric is a certainty, and one that enabled our very existence.”
Today, American Thanksgiving, is a day to appreciate the good things we have in life. That includes the people who love us and that we love, the things that make us feel good, fulfilled, happy, and well, and the bounty that this world provides. But it goes beyond that, too, to the natural gifts of the Universe that enabled us to be here in the first place. Here are 10 scientific phenomena that enabled our existence, our world, and our very lives. Without them, there would be no Earth, no humans, and no opportunity to give thanks for the cosmic blessings that allow us to simply be. Take a moment to give thanks for all the good things we have, and take a moment to appreciate the fact that this Universe, exactly as it is, allows you and I to be here inhabiting it.
