The black sphere in molecular modeling kits represents a carbon atom, which can form up to four chemical bonds due to its atomic structure and electron configuration. The four holes represent the four locations where the carbon atom can share or receive electrons to form these bonds with other atoms.

Why are black holes round?
Black holes are round due to the intense gravitational forces pulling matter towards the center. This gravity acts equally in all directions, resulting in a spherical shape. Any irregularities in shape would be quickly smoothed out by the immense gravitational forces at play.
Can black holes dies?
Black holes do not die but they can evaporate.
What subjects other than astronomy would astronomers have to study in order to discover black holes?
Astronomers studying black holes would typically need to study physics, particularly in the areas of general relativity, quantum mechanics, and thermodynamics, to understand the nature and behavior of black holes. They may also need to study astrophysics, cosmology, and computational modeling to analyze observational data and simulate black hole interactions with their surroundings.
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
WhAT feature is found with Kerr black holes but not schwarzschild black holes?
Ergoregion
Did people really think of the Earth as a sphere and black holes?
No
How do black holes in space get their name?
A black hole is an objects with such strong gravity that not even light can escape them. If observed up close a black hole would appear as a completely black sphere.
Why are black holes round?
Black holes are round due to the intense gravitational forces pulling matter towards the center. This gravity acts equally in all directions, resulting in a spherical shape. Any irregularities in shape would be quickly smoothed out by the immense gravitational forces at play.
What is the sphere around a collapsed star from which light can not emerge called?
That refers specifically to black holes (there are other types of "collapsed stars"). This sphere is called the "event horizon".
What evidence leads us to believe that AGNs contain supermassive black holes?
We can detect amounts of electromagnetic radiation being emitted from the centers of galaxies that correlate with those emitted by black holes, as well behavior associated with behavior of black holes whenever amounts of material enter the 'sphere of influence' of the black hole, i.e. the accretion disks found near AGNs being sucked into the theoretical super-massive black hole.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Can black holes dies?
Black holes do not die but they can evaporate.
How do black holes get into your solar system?
There are no black holes in our solar system
What are the stars called when they become black holes?
They are called "black holes".
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
After whom are non-rotating black holes named?
Schwarzschild black holes. Named after the scientist who proved mathematically black holes can exist.
