340: Uncovering the Dark Side: Is Dark Energy Coming from Black Holes?

When listener Daniel poses a theory linking black holes to dark matter and dark energy, Andrew and Fred embark on an adventure to uncover the truth and explore the potential for a Nobel Prize, but must prove the revolutionary theory before time runs out. You will learn how to unlock the secrets of the mysterious dark energy that powers the universe.
Show Notes Learn about Dark energy with Andrew Dunkley and Professor Fred Watson. They discussed the potential for the discovery of a source for dark energy, which Daniel from Adelaide theorized could be black holes that suck up normal matter and energy and convert them to dark matter and dark energy. C0-incidentally, a paper published this week links black holes to dark energy, but not dark matter. It states that black holes generate an energy that is somehow coupled to the universe's expansion, providing the energy required for the universe's acceleration. Duncan Farrer of the University of Hawaii said that this is the first proposed astrophyiscal source for dark energy and could result in a Nobel Prize. Lastly, they discussed the danger of rubble pile asteroids, and other listener questions. "Keep an eye on your letterboxes, because that's sure to arrive. Great stuff, Daniel. And you are, in a sense, ahead of the curve there because for the first time we've seen this week a paper, scientific paper, that exactly does that links black holes with dark energy. Not with dark matter, but with dark energy. Now, what is different from the Daniel theory is the mechanism for this. It doesn't involve things being spat out of black holes at speed of light'. In this episode, you will learn the following:

Could black holes be the source of dark matter and dark energy?
Are black holes the source of the energy that is causing the universe to expand ever more rapidly?
What would happen if the Earth's magnetic field flipped?
