Supernovas that we can actually observe with the naked eye are few and far between. The last one, Kepler's Star, happened in 1604, and there are typically a few during each century.
Of course, we have powerful technology that allows us to photograph supernovas and because of that, we have beautiful, colorful photos of these star explosions. A one last burst of colorful light from a massive explosion that marks the beginning of the end for a star. It's positively beautiful and poetic.

Nothing can actually be absolute zero because this is when thermal motion cannot actually be motion anymore. It's too darn cold. For people who don't remember their physics, absolute zero is 0 K, which is -273 degrees Celsius.
Hooke's law is a principle of physics stating "that the force used to extend or compress a spring by some distance is proportional to that distance." It's used everywhere, in all branches of science and engineering.
This is the universe. Somewhere in this thing, there should be plenty of antimatter. There has got to be enough antimatter to balance out the regular matter, so where is all the antimatter? Well, it's obviously somewhere, we just don't know where to look. Here are some possible hiding places:
I just finished watching the new film Hidden Figures. It is about physicist and mathematician, Katherine Johnson as well as mathematician Dorothy Vaughan and engineer Mary Jackson, all of whom worked for NASA. It's about time these women got some recognition for their accomplishments.
According to good ol' Science Daily, wave-particle duality is the idea that light and matter both have properties of waves and particles. There was recently a flaw discovered in this theory but it was shut down.
