  1. The coolest application of the difference that I have heard is that neutrino telescopes may be able to detect supernovea before they are visible. The neutrinos released in the event travel straight out of the exploding star, but the photons aren't released until the density of the resulting nebula is low enough to let them escape.

  2. The question of gravity on a super earth is actually a bit more complicated. The strength of gravity depends on density of mass, not just the amount of it. A planet could potentially be much larger than earth but have similar or even lower gravity at the surface if it was super rich in aluminum and silicates. A smaller planet with a much higher concentration of heavy metals in the core could have higher gravity at the surface. Remember that gravitational force falls off as the inverse square of the distance and on a larger planet you are further from the center.

  3. They can. The technology used for it is also useful for weapons tech though. The French have led development since Carter banned it but America picks up the idea every once in a while. Of course, there’s plenty of fission fuel easily mineable and we may well get fusion going before it runs out.

  5. One of the coolest physics experiments out there. Amazing summary.

  6. Israel also sent a spacecraft there. It crashed... but it got there.

  8. Way too expensive, but burying it at subduction zones in the ocean would work a treat.

  9. While there is extreme friction, most of the reentry heating is adiabatic compression. Basically, the craft is acting like a piston compressing the atmosphere ahead of it.

  11. Exactly. Very nearly anywhere not near earth is all equally acceptable.
