What would a black dwarf be like?

AI Thread Summary
A black dwarf, formed from a cooled white dwarf, would be an extremely cold, dense object emitting no visible light. After cooling to around 70 degrees Fahrenheit, it would resemble a dark, inert mass, often likened to a giant charcoal briquette. The lack of light and heat would make it relatively unremarkable, with minimal activity aside from potential collisions with other objects. Overall, it would be a stable but boring celestial body. The discussion emphasizes the unexciting nature of a black dwarf's existence in the universe.

What would a white dwarf be like after a long enough time that it had cooled to 70 degrees F and emitted no visible light?

I think you've covered it, actually. It would be pretty cold and wouldn't emit much light. It would just be a dense, spinning ball. Occasionally something might crash into it, and get squished to a pulp. Pretty boring to a first approximation.

Dark! :biggrin:
 
A giant charcoal briquette is the best description I heard.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
