Could Black Holes Be the Opposite of Suns in the Big Bang Theory?

In summary, black holes are collapsed stars that have their mass collapsed past a cerain point defined by the Schwarzschild Radius equation. They are just like any other star, but have an event horizon that defines the point past which they are no longer considered a part of the universe.

I am just wondering about the big bang theory. If galaxies are traveling away from us at great speeds, what about the black holes? Where does black holes fit into the big bang theory? Could it be possible black holes can be the opposite of a sun, despite it's gravitational pull?

The big bang and black holes are independent of each other. Black holes are collapsed stars that have their mass collapsed past a cerain point defined by the Schwarzschild Radius equation

R= 2GM/c^2

Where M is the mass collapsing down to the event horizon which is the radius we are defining

In general (for this question), you can consider a black hole like any other star...black holes orbit the galactic center and are carried with the galaxy as space expands. A black hole is an object embedded in spacetime just like anything else. Granted, as you examine it closely, it's an object with some amazing properties, but it's not something separated from this universe.

Could it be possible black holes can be the opposite of a sun, despite it's gravitational pull?

Not sure what you mean.

Stephen Hawking postulated the existence of primordial, substellar mass black holes that 'froze' out of the big bang mess due to slight density differences in the early universe. No observational evidence of these mighty midgits has been found to date [some of them should be evaporating via Hawking radiation by now]. This would not affect expansion. A black hole has no special properties, aside from it's very high density. Save for matter very nearby, the rest of the universe would treat them no different than any other gravitating object. [i.e., same as what Phobos said]

diameter is 3km ,if our sun become a black hole.
 

1. What is the big bang theory?

The big bang theory is a scientific explanation for the origin of the universe. It suggests that the universe began as a singularity, a tiny point with infinite density and temperature, and expanded rapidly about 13.8 billion years ago, creating all matter and energy in the universe.

2. How was the big bang theory discovered?

The big bang theory was first proposed in the 1920s by Belgian physicist Georges Lemaitre, who noticed that the universe appeared to be expanding. This was later supported by observations made by astronomer Edwin Hubble, who discovered that galaxies were moving away from each other at a rate proportional to their distance.

3. What evidence supports the big bang theory?

There are several pieces of evidence that support the big bang theory, including the cosmic microwave background radiation, the abundance of light elements in the universe, and the large-scale distribution of galaxies. These observations are consistent with the predictions of the big bang theory.

4. What are black holes?

Black holes are extremely dense objects with such strong gravitational pull that not even light can escape from them. They are formed when a massive star dies and collapses in on itself, creating a singularity with infinite density and no volume.

5. How are black holes related to the big bang theory?

While black holes are not directly related to the big bang itself, they provide important insights into the early universe. The study of black holes helps us understand the effects of gravity and the behavior of matter in extreme conditions, which can ultimately help us understand the origins of the universe.
