        Dr. Tyson, I just turned 50, and I have serious concerns that my eyebrow growth is violating the law of conservation of mass.

        Is the short answer gravity? That's what I've always assumed, without running any simulations (or an idea of how to set them up).

        Yeah. Since in the early days after the big bang all the planets were essentially molten rocks, gravity shaped them.

        That wouldn't be from the big bang, which produced H and He, it would be from dying stars that fissioned those elements into heavier ones.

        Thats true. I just meant the early days of planets not the literal first days.

        I'm learning GIS in college atm, and what "shape" the Earth is depends upon application as well as perspective and scale.
