Question: why is your life dust

Bella Boulderstone answered on 11 Jun 2019:

My life is dust because that’s what I primarily study! I think it’s a little funny that my entire field of work is just obsessed with different types of dust. For instance, I study graphite, just like in your pencils. Tiny, tiny particles of graphite which (under the right temperature and pressure) will sublimate (turn from a solid to a gas, like dry ice) at ~2,200 degrees Celsius. Because temperatures are related to different wavelengths of light (hotter things are seen in gamma rays, cooler things emit radio waves), we know that this temperature can be ‘seen’ in the infrared (like heat vision). We can watch the light coming from the dust and see what’s going on where the dust is doing its sublimation thing!
