Could the Sun Contain a Primordial Black Hole?

TL;DR

Primordial black holes, which may have formed during the early universe, could explain the mystery of dark matter and have implications for the evolution of stars like the sun.

Transcript

Sometimes in the course of solving mysteries in astronomy, ideas are advanced to explain a discrepancy that are considered for a time because they are plausible, but ultimately fall off the table when the problem is solved through other means. A good example of this is the now solved solar neutrino problem, which was a hotly debated mystery for dec... Read More

Questions & Answers

Q: What is the solar neutrino problem and how was it solved?

The solar neutrino problem refers to the discrepancy between predicted and measured solar neutrino flux. It was solved in 2002 when it was discovered that neutrinos have mass and can change states.

Q: How could primordial black holes explain dark matter?

Primordial black holes, if they exist, could account for the gravitational effects attributed to dark matter. They would provide an alternative explanation without the need for new particles or unknown physics.

Q: What are red straggler stars and how could they be linked to primordial black holes?

Red straggler stars are a type of star that defies normal stellar temperature classification. They could potentially have a primordial black hole at their center, causing their peculiar behavior.

Q: How might primordial black holes have formed in the early universe?

Primordial black holes may have formed during the inflationary era of the big bang, when dense areas of subatomic particles underwent gravitational collapse.

Summary & Key Takeaways

• In the 1960s, a discrepancy in solar neutrino measurements led to the proposal that a primordial black hole could exist at the center of the sun, although this was later debunked.

• Dark matter, which exerts a gravitational influence greater than visible matter, remains a mystery. Primordial black holes are a possible explanation for dark matter.

• Red straggler stars, which defy normal stellar behavior, could be explained by the presence of primordial black holes at their centers.
