How accurate a clock do you really need, honestly? You'll still probably show up late to parties and dial exactly three minutes late into every scheduled phone call. But scientists creating ultra-precise new atomic clocks don't really have you in mind. Instead, they're using wild physics to understand mysteries of the Universe that could alter time itself.

Should you find yourself inside a black hole, you will die. Should you find yourself near a black hole, you will also die. Aside from the fact that these massive, light-trapping monsters are impossible to reach on human timescales, there are simply not many ways measure the plasma surrounding them without dying or destroying the experiment. Scientists have to make do by recreating some of the features in the lab.
If you were to rank the wildest things in the universe, there are a few obvious contenders: Gamma rays, fast radio bursts and quasars, for example. But no list would be complete without black holes and the black hole's less-dense cousins, the neutron star. These hyper-compressed things can do some mind-boggling warping to the shape of space itself. So, what happens if one were to eat the other?
Particle accelerators have a lot of important jobs, such as looking for new stuff by slamming beams of old stuff together. But a new particle accelerator observation has managed to be important while doing almost precisely the opposite of what we'd expect. Physicists have found evidence for hard-to-detect stuff by, well, not slamming particles together.
You are very lucky that you ended up about the size that you are today, somewhere between 30cm and 3m tall and weighing somewhere between 0.5 and 500kg. This is a very good size. Not to body shame, but if you were, say, a quadrillion times shorter and weighed a nonillion times less (that's one followed by 30 zeros), that would be very inconvenient for you. Everything would be very inconvenient for you.
Water has some special properties you've surely heard about in high school chemistry. Most notably, it sticks to itself really well. It beads together, looks like this in space, and climbs up plants' vascular systems, all thanks to hydrogen bonds. Now, scientists have figured out exactly how sticky those ubiquitous bonds are.
