Universe Today Podcast

In this week's questions show, I talk about the Dark Forest theory in the Three-Body Problem series of books. Is it a compelling answer to the Fermi Paradox? How much of a risk is dust to interstellar travel? Is black hole evaporation negated by black holes absorbing additional material and energy?

This week my guest is Australian astronomer Fred Watson. He's a writer, researcher and Australia's Astronomer at Large.

In this week's live questions show, I talk about the possibility of life on exomoons and why they'll be important targets to search. Why I hate the embargo system for news, and the announcement of water on the Moon.

In this week's live QA, I give updates on the discovery of phosphine at Venus, how the Universe could be compressed into a singularity leading to a Big Bang, and more...

This week I'll be talking Dr. Seth Shostak from the SETI Institute about his work searching the Universe for evidence of extraterrestrials. Check out Seth's podcast at: http://radio.seti.org/

Here's a guest interview I did with Ralph Crewe on his podcast "Isn't That Something" talking about the 2020 Mars Opposition. Check out the podcast at: https://ralphcrewe.podbean.com/

In this week's live questions show, I answer questions about drilling for microbes on Mars, missions that could survive the surface of Venus, and if anyone else is dissatisfied with the Big Bang.

Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, you’d still end up at the singularity.

Astronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well.

But there’s a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter.

Primordial black holes.

This week I'll be talking with astronomer Scott Gaudi from Ohio State University about the search for habitable exoplanets and NASA's HabEx mission.

Did Venus life hitch a ride on the Venera missions? Could we use life to terraform Venus? Life on Venus? Booooring.
