Title: Ep. Astronomy Cast: Questions Show: Matter Balance, Jumping Light Speed and Black Hole Star Formation
Organization: Astronomy Cast

Description
Why was there a difference between the amount of matter and antimatter at the beginning of the Universe? Mathematics lets us travel faster than light speed, so why can’t we? And are there stars forming around black holes?
Bio: Fraser Cain is the publisher of Universe Today and Dr. Pamela Gay is a Senior Scientist at Planetary Science Institute and a Director of CosmoQuest. They team up to do Astronomy Cast, a weekly facts-based journey through the cosmos

Summary:
– Why was there a difference between the amount of matter and antimatter at the beginning of the Universe? Do black holes have something to do with this?
– Mathematically, we can have a velocity greater than the speed of lights lets us travel faster than light speed, so why can’t we?
– Can stars form in accretion disks around black holes?
– How much precision is needed to keep space telescopes focused on one spot? I have a hard enough time keeping my camera steady!
– How can matter exist with antimatter?
– What causes sunspots and do they influence Earth in any way?
– How do we know what the speed of light is? How can we measure something that fast and how did scientists figure that out?
– Would life as we know it be able to survive around a Red Dwarf?
– Could matter escape from the event horizon of two black holes colliding?
– Why is it so bright in the center of the galaxy with a black hole there?
– What is behind a black hole?
