Do you know how large the universe really is? I mean, most people know but they don't actually realize it. If you ever want to understand the enormity of it, just try to expand outwards starting with the Earth.
So, there's our planet, and then the solar system with the Sun at the center. There are hundreds of billions of stars in our Milky Way galaxy among which our Star is just one.
Then there are an estimated 2 trillion galaxies (2000 billion) in the universe. What's more, there could be infinitely more galaxies outside of the area of the universe that we have been able to observe till now.
The universe is so huge that the word "huge" fails short in comparison. So, now the question arises... how do we meaningfully explore a universe so huge? None of our current methods are good enough for even interstellar travel!
Wormholes To The Rescue
For the longest time, wormholes have been used in science fiction as a means to reach the furthest points in the universe in the blink of an eye. In very basic terms, they are shortcuts to two points in space and one can get inside one mouth of the wormhole and come out of the other almost instantly, no matter how far it is.
But wormholes are not only in the domain of science fiction. In fact, certain solutions of Einstein's general relativity allow for the existence of wormholes where the mouth of each is a black hole.
Now, a team of physicists says that it has found a way to make them possible. They say their theory allow for a stable wormhole that humans could actually travel through. It would allow travelers to travel about 10,000 light-years in a single second.
At this point the whole thing is theoretical. And with our current technology, it seems impossible to create such a wormhole. But who knows what we'll be able to do in the next 1000 years! Maybe one day we will indeed be able to create wormholes and go anywhere we desire in the universe.
