Submarine for Titan, Planets Changing Size, Even Bigger LIGO | Q&A 230
When does a Lagrange point stop being one? Can we make LIGO even bigger? Do planets change their size over time? Can we build a submarine to go to Titan? What's next for the TRAPPIST-1 system? All this and more in this week's Q&A!

Mustafar: this follows on from the Hoth question. Talking of diamond presses creating metallic hydrogen they can create "hot ice" that's water ice more dense than water and doesn't melt until 125deg C. Just imagine ice cubes that put into boiling water sink and don't melt! Question: could the release of extra latent heat of fussion when ices are compressed under extreme pressure explain the apparent upwelling of heat on Pluto?
Hoth: an interesting question. Comparing the planets in our solar system demonstrates the deviation from the classical model for the states of matter (solid, liquid, gas) and how size isn't strictly related to mass, composition and temperature.
