Black Hole Star – The Star That Shouldn't Exist

Black Hole Stars

This video discusses the concept of black hole stars, which were massive stars that existed in the early universe and were occupied by a black hole.

What are black hole stars?

• Black hole stars were massive stars that existed during a short window of time in the early universe.

• They were much larger than any star today, with up to 10 million solar masses of nearly pure hydrogen.

• These stars had a black hole growing rapidly at their core as they devoured billions upon billions of tons of matter per second.

How did they form?

• Black hole stars formed from epic clouds of hydrogen, some as massive as 100 million suns, concentrated by dark matter halos.

• The enormous gravitational pull of these dark matter halos drew gas into their center and created extremely massive stars.

• Unlike normal stars, these titanic gas clouds were so large and massive that even after their birth more and more gas piled on the newborn star making it grow to unbelievable proportions.

What makes them different from normal stars?

• Nuclear fusion releases enough radiation energy that the surrounding gas cloud is blown away. The new baby star can't gather more mass from now on.

• After millions or billions of years, the core runs out of fuel and the balance breaks destroying the star. But black hole stars survive their own death because they are so large and massive but not even a supernova can destroy them.

• When a black hole is born from the core of a star, it keeps its angular momentum. This means that matter that gets drawn in doesn't just fall in a straight line but instead begins orbiting the black hole in smaller and smaller circles going faster and faster.

How do they consume matter?

• Black holes put a lot of food on the table and only nibble at it. But the matter trapped in the accretion disk doesn't have a good time.

• A black hole embedded inside a black hole star is different. The enormous pressure surrounding it pushes down matter directly into the black hole overcoming all restrictions on how fast it can consume.

The Largest Star to Ever Exist in the Universe

This section discusses black hole stars and how they could explain the existence of supermassive black holes.

Black Hole Stars

• Black hole stars are formed when a star collapses under its own gravity, creating a black hole.

• As the black hole star feeds on matter, it heats up and expands, becoming over 30 times wider than our solar system.

• When the accretion disc within becomes too powerful, the parasite destroys its host, blowing it apart.

• Black holes born from regular supernovas can be a few tens of solar masses at most and grow slowly after that.

• However, if black holes merge they can form slightly larger black holes of over a hundred solar masses.

• If black hole stars existed and formed very early in our universe with thousands of solar masses, then they could be the seeds for supermassive black holes.

• These seeds could take root in the center of earliest galaxies merging with others and drawing in enough matter to grow quickly and reliably.

Supermassive Black Holes

• Supermassive black holes we see at the center of galaxies are just too big to have been formed by regular supernovas.

• It should take billions and billions of years to make black holes with hundreds of thousands or even millions of solar masses.

• Yet we know that some supermassive black holes already had 800 million solar masses only 690 million years after the big bang.

• Black hole stars could explain one of the greatest mysteries of the universe, the supermassive black holes we see at the center of galaxies.

Future Discoveries

• The James Webb Space Telescope is turning its senses to explore the farthest reaches of the universe looking back in time.

• With luck, we might be able to witness glimpses of these tragic Titans in the brief moment between their formation and destruction.

• Until then, let's do a visual journey again just for fun.
