1. What establishes the axis and direction of spin of spiral galaxies in 3 dimensional space?
2. Couldn’t we go to the Trappist system in the next 100 years? We build an advanced AI ship with enough fusion energy to power the ship with millions of embryos, eggs and sperm that are 'hatched' when the ship gets there and educates them on how special they are. Fiction? If realistic, why hasn't it already happened?
3. Do you feel we are unique? It seems that statistics and that life exists here would imply that it exists everywhere in the universe with water, heat, and more dense molecules.
4. Measuring the metal enrichment in pulsating stars: is this a measure of quantity only or does it allow you to determine the number of types of metals that the star contains?
5. Didn’t Tycho Brahe’s observations help validate the Crab Nebula’s age?
6. What proof do we have that the big bang actually happened?
