Wormholes

What Are Black Holes?
Black holes form when massive stars collapse under their own gravity, creating an intense gravitational pull that even light can’t escape. For years, scientists believed black holes had infinite gravity and collapsed into a single point, known as a singularity.

Spinning Black Holes
In 1963, physicist Roy Kerr discovered something remarkable: spinning black holes don’t collapse to a single point but form a stable, spinning ring. This spinning ring could potentially lead to something even more incredible—a wormhole connecting different parts of the universe!

Wormholes and the Science Behind Them
The idea is that a black hole could connect to a white hole, a theoretical object that releases matter instead of swallowing it. Although no white holes have been observed, scientists continue to explore this exciting possibility.

Balancing a Wormhole
For a wormhole to stay open, there needs to be a careful balance between positive and negative energy. Black holes naturally provide the positive energy needed to create the gateway. However, scientists believe that artificially adding negative matter or energy might stabilize the wormhole, preventing it from collapsing.

What Is Negative Matter?
Negative matter, unlike antimatter, has antigravitational properties, meaning it would fall up rather than down. While it has never been detected in nature, physicists have managed to create negative energy in the lab, though in quantities far too small to stabilize a wormhole or drive a spaceship.

Wormholes remain a theoretical possibility, but scientists continue to study black holes to unlock more secrets of the universe. Could wormholes one day provide the key to interstellar travel?
