Shockwaves are a familiar phenomenon here on Earth. In astrophysics, they play a role in some of the most powerful events in the universe, from exploding stars to gamma ray bursts. Shockwaves can…
So I, I think most people are at least familiar with the concept that, you know, a shock wave is something you get when you have an explosion.
Um, or just in general, when you, you put too much energy into a system too fast-
... um, so that things are moving, you know, much faster than the speed of sound.
And the connection to astrophysics is that, um, we very often have this situation.
Um, there's many situations in astrophysics where you suddenly release some sort of energy.
Um, but there's lots of processes that, that release a huge amount of energy suddenly, and those systems are usually surrounded by some sort of gas, and, and so shock waves go out through that gas.
Um, and the reason that they're interesting is because, you know, they can create quite bright emission, which we then observe.
Um, so when we see the lights, um, from observing these systems, uh, we can sometimes trace back, you know, was it created by a shock wave? And, and if so, what were the properties of that shock wave? And that tells us something about the explosion and about the environment.
So, um, I guess maybe, like, um, a physics-y or a picture, you know, that people can have in their heads, you know, of like a, a, like a terrestrial version of a shock wave, you can imagine is like a nuclear blast, right? Or something like that.
