Main Difference
The main difference between Black Hole and Wormhole is that Black Hole is a cosmic body that has high gravity, and nothing can pass from it, whereas the Wormhole is the funnel-like space-time that connects two points between universes.
Black Hole vs. Wormhole
Black Hole is a highly-dense material that has an excessive quantity of matter and energy, and nothing can pass from them; even light cannot pass from that, so its name is a black hole having a strong gravity around it and destroy the space-time passing it. Wormhole connects two points in two different regions or two universes, and they exist only in physics fiction or theory.
The concept of black hole present in Einstein’s theory of relativity and astrophysics, while wormholes relate to Einstein’s theory of relativity and quantum physics, and an American physician John Wheeler named it as a wormhole.
Black Hole exists, and it can pull the things due to their higher gravity, and it not seen directly but identified by pulling objects. Wormholes did not discover by anyone in the known world. The size of a black hole can be different; it can be smaller than an atom, or it can be larger than stars. The size of the wormhole is not known yet.
The black hole can pull the material, and that will not exist more on the universe because that will enter into a black hole. The wormhole provides a pathway to connect the two points between two regions/ universes.
Black holes needed a high amount of energy, matter, and density. A wormhole remains static and unchangeable in the presence of the smallest approximately negative amount of energy.

What is a Black Hole?
Black holes are locations in the universe that possess a high gravity and can drag any object into it; even the fast-moving particles like light cannot break out its gravitational field. The term black hole formulated by a German scientist Karl Schwarzschild from Einstein’s theory of relativity. He considered that mass has squeezing ability so that it can change in unlimited small points and bend space-time around it so that anything even light photons with no mass could not break its curvature.
The formation of a black hole occurs when a large star that has a massive quantity of matter and energy destroys. The exhaustion of the thermonuclear fuel of star into its core ends up the life of a star. The core of the star becomes volatile and collapses towards the inside due to the higher field of gravity. The outer layer of the star becomes dispatched, and a dense ball remained.
The different parts of the black hole include the ergosphere, the singularity, and the event horizon. The ergosphere is the outer most part where the gravity stars pulling things. Singularity is the term used for the center of a black hole. The surface of a black hole that connects to an object is called the event horizon. At the interior surface of the event horizon, the escape velocity is higher than the velocity of light and stops the passage of the light rays from the black hole.
The radius of non -rotating black hole can be calculated easily from the equation that mass is directly proportional to the radius.
What is Wormhole?
The wormhole is an interesting topic in the field of science/ physics fiction. The concept was evaluated from the theory of relativity and suggested by Albert Einstein and Rosen. The name wormhole termed by John Wheeler. The wormhole is a pathway that works like a bridge for two points in space and time and attaches them. It can also define in words; A theoretical method of space-time folding to patch up two points in different regions/places in space. According to its concept, one can travel in seconds from one region to another.
The wormhole is a theoretical concept, and scientists are not sure about its existence because of no strong shreds of evidence. Theoretically, a wormhole is a funnel that has two mouths and one throat/ neck — the throat act as a connecting shaft for the two mouths. The scientists consider that a wormhole may exist, and its mouths open up in two different black holes. The black holes created from the collapse of stars cannot form the wormhole.
The confirmation of the existence of wormhole can be widely advantageous for humankind. It can provide shortcuts in space; allow the travel into past time, and can reduce the journey of days into instances.
The size and diameter of a wormhole considered 10-33 m, and it will have a very short life period. The energy requirement of a wormhole is in a negative amount. The negative energy is essential to keep a wormhole static and unchangeable. Till today nobody has seen a practical wormhole in space but the major subject in theoretical physics.
Key Differences
Conclusion
The study concludes that Black Holes are space materials with a strong gravitational field and high mass and energy density, and they do not allow the escape of objects, while Wormholes are pathways that allow the connection between two points in two different universes.
