What did Hubble really discover? Why does redshift imply an expanding universe? Why is the night sky dark? Why is there so much hydrogen, and how is that connected to the Big Bang? I discuss these questions and more in today’s Ask a Spaceman!

AaS! 72: How does gravity make a lens?

How does gravity bend the path of light? Does it seriously act like a lens or is that just a metaphor? What does it take, and how do we know? What can we learn from this strange physics? I discuss these questions and more in today’s Ask a Spaceman!

AaS! 71: Who lives in the particle zoo?

neutron-star-720x340.jpg

What strange creatures inhabit the so-called “particle zoo”?  Why is it a zoo instead of something simpler? Is there anything that connects the forces and particles of our universe? I discuss these questions and more in today’s Ask a Spaceman!

How does degeneracy pressure work? What kinds of particles exist below the level of neutrons? Can they hold up a star against gravity?  I discuss these questions and more in today’s Ask a Spaceman!
