Anyone interested in this topic? or matters concerning the universe? I find it endlessly interesting to think about gravity and the Big Bang, expansion of the universe, all those things related to astronomy. (not astrology)
I like finding out why the earth has an atmosphere and the moon and many planets do not. (molten iron core sets up magnetic force-field that shields solar wind which would strip atmosphere if mag field not present.) Stuff like this.
Black holes and worm holes. Theories of space texture and shape. All this stuff tends to make you feel completely insignificant. For some reason this appeals to me.
Einstein and his thoughts, parallel universes, time-space continuum. Time travel. Endless possibilities of other earth-like planets, even a Pandora.
I never liked TV Star Trek or Star Wars but I like the subject of astronomy.
