  • The right side of history

    Space IS nuts. I like this pod, I see people leaving negative reviews on politics. In the US its influence on space is notable. Just be on the right side of history.

Talking Points

Recent interactions between the hosts and their guests.

Dark Matter Mysteries, Telescope Innovations & the Quest for Gravitons | SN602 Q&A
Q: Why does physics discuss the hypothetical graviton as a force carrier for gravity and what would it look like?
The graviton is proposed as a boson that would explain gravity in quantum terms, similar to how other forces have force-carrying particles like photons.
Dark Matter Mysteries, Telescope Innovations & the Quest for Gravitons | SN602 Q&A
Q: If you could pick the next large telescope to be launched, what would it be and why?
The Extremely Large Telescope (ELT) in Chile, with its advanced adaptive optics, which will provide remarkable resolution and has a cost-effectiveness compared to space telescopes.
Dark Matter Mysteries, Telescope Innovations & the Quest for Gravitons | SN602 Q&A
Q: How do we know or measure that 80 percent of matter is missing or not visible to us?
We determine that by measuring the motions of galaxies and their gravitational interactions, using both historical and modern astronomical techniques, including fiber optics and large scale galaxy surveys.
Cosmic Questions: Dark Energy, Stellar Birth & the Nature of Black Holes
Q: Does the expansion of space mean that the universe gains more meters, or are the meters becoming longer?
The meters are becoming longer due to the expansion of the universe, which stretches wavelengths.
Cosmic Questions: Dark Energy, Stellar Birth & the Nature of Black Holes
Q: If material accretes close to the event horizon, is it extremely hot, and does it suddenly become cold when it enters the event horizon?
It's still extremely hot but does not emit anything, making it appear cold to an outside observer.
