Odd Black Hole Defies Explanation : space.com

In summary, these papers present evidence that "most" blackholes that have been detected so far are actually white-holes due to the immense enegetic luminous outpourings from the objects. This suggests that most blackholes are not as dense as originally thought and that they may not be as dangerous as was once thought.

"Odd Black Hole Defies Explanation": space.com

Astronomers have found what appears to be a black hole 25 to 40 times the mass of our Sun, a weight class not previously known to exist.

Black holes can't be seen, because any light that enters them is trapped. So to find black holes, scientists look for intense radiation from around them as well as their gravitational effects on nearby gas and stars.

Black holes come in two distinct varieties, scientists know. A stellar black hole results from the collapse of a single, massive star and is typically a few times the mass of the Sun. Supermassive black holes anchor the centers of many galaxies and can harbor millions or billions of solar masses.

"There's a big gap there," said Philip Kaaret of the Harvard-Smithsonian Center for Astrophysics. Kaaret thinks he's found one that helps fill the gap.[continued]

any massive body can gravitationally collapse into a black hole. the mass and distance limits are well known. the consequences are not yet predictable.

Huhmm?..It seems that the only way to detect 'Blackholes' is to find the 'Light' that theoretically should 'NOT' be emminating from a BH!..so consequently most of the Blackholes detected so far have been really 'White-Holes' due to the enormous enegetic luminous outpourings, co-incidence?

The quoted author from the link tells me that he does not actually know the difference between a young stella object's creationary period (timescale) and the intermediate lifespan of a comparable early Galactic Star?

Q:How long does it take to produce a Star that matches the Mass of the "detected" Blackhole, What is the predected Stella Lifespan?

Q:How long does it take to produce a Blackhole that Matches an early 'baby' Stella Object, can the Blackhole's current Mass, reveal anything about the Star's lifespan that is proposed to have created it, is there a 'Time-stamp' to suggest how old the Star was at the instant it created the 'current-BH'?

Actually I found some recent papers that have highlighted this very problem, for those that are interested:

http://uk.arxiv.org/abs/astro-ph/0406217

http://uk.arxiv.org/abs/astro-ph/0406218

http://uk.arxiv.org/abs/astro-ph/0406219

Three very interesting papers!
 

1. What is the odd black hole that defies explanation?

The odd black hole that defies explanation is a black hole located in the galaxy of GSN 069, which has been observed to be emitting bright, high-energy flares despite being relatively small in size.

2. How is this black hole different from other black holes?

This black hole is different from other black holes due to its size and the intensity of its flares. It is much smaller than most black holes, yet it is producing some of the brightest flares ever observed from a black hole.

3. What is causing the intense flares emitted by this black hole?

The exact cause of the intense flares emitted by this black hole is still unknown. However, scientists believe that it could be due to the interaction between the black hole and its surrounding environment, such as a nearby star or a disk of gas and dust.

4. How did scientists discover this odd black hole?

This odd black hole was discovered by NASA's Chandra X-ray Observatory in 2006. Scientists were studying a galaxy cluster when they noticed a bright X-ray source, which turned out to be the odd black hole in question.

5. What can we learn from studying this odd black hole?

Studying this odd black hole can provide valuable insights into the behavior and characteristics of black holes. It can also help us better understand the processes that drive the emission of high-energy flares from black holes, which may have implications for our understanding of the universe as a whole.
