Questions Show – Black Hole Surfaces, Magnetic Field Strengths, and the Speed of Gravitons

As you know, we wanted to answer listener questions regularly, but we found it was taking away from the regular weekly episodes of Astronomy Cast. So we’ve decided to just split it up and run the question shows separately from the regular Astronomy Cast episodes. If this works out, you might be able to enjoy twice the number of Astronomy Cast episodes. So if you’ve got a question on a topic we cover in a recent show, or you just have a general astronomy question, send it in to info@astronomycast.com. Either by email, or record your question and email in the audio file.

    Does a black hole have a definite surface?

    How does the size of a magnetic field come into play for astronomical object vs. bar magnets

    Could dark energy be the uncurving of space?

    Do gravitons travel at twice the speed of light?

    Is the amount of gravity that comes from an object come from every molecule in the object?

    Is there a balance between the pull of gravity and the repulsion of magnetism?
