Just waiting for dinner and thought about the enigma of what are termed “black holes”.
What an unfortunate name to apply to a large, extremely dense mass. I suppose an accurate term might be “black mass” but that has unfortunate connotations 🙂 .
They ‘appear’ as holes simply because light can not be emitted from them, explanation follows.
But there can be objects “on the other side” far enough away to not be part of the black hole, you would obviously not see them, as you might if there was really a hole.
So, any science fiction that suggests they can become a minute singularity, through which one might pass into another universe, perhaps, makes no sense, to me!
This is both serious and for fun, just as a light diversion.
Refer to ” https://science.nasa.gov/astrophysics/focus-areas/black-holes ” for serious information.
Don’t let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area – think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space.
