Hi, I'm Michael and new to this forum. I get excited about space, science, and learning new things about the universe. I love how science evolves our understanding of the universe. Some galaxies are 45 billion light years from ours. We believe nothing can travel faster than the speed of light, yet the 'big bang' occurred only 14 billion years ago. Hmmmm. Space itself must be expanding. Hmmmm.
Gravity affects light, yet Gravity only affects particles with mass. Hmmmm.
80% of the mass of the universe is dark matter. Maybe in lots of small black holes? Wow!
So much I have to learn.
