Wormhole can create a tunnel in the spacetime for intergalactic transportation

When scientists talk about travel to distant galaxies or planets, then they always imagine this travel with the help of a wormhole. Albert Einstein formulated the theory of wormhole along with Nathan Rosen. They used the General relativity theory to explain the existence of wormhole. According to this theory, a wormhole is a tunnel in the spacetime, and this tunnel can reduce the distance of two places in a great way, and that will minimize the time of travel as well. You can consider this similar to a tunnel that is crossing from inside a mountain so that it can reduce your distance and travel time for the faster journey.

Thanks to some science fiction movies related to space travel, now those people are also aware of the wormhole that do not have any direct connection with physics. Several movies fit in this criterion, but interstellar is possibly the most fantastic movie on this subject. This is a film in which a team of astronauts travels to distant galaxies via wormhole so they can find a new home for the human kind because the planet earth was dying slowly. This movie not only talks about the wormhole, but it talked about the theory spacetime continuum as well that says, time could be relative to people.

Although, Interstellar is a fantastic movie, but traveling through a wormhole is still not practical at this point because of various reasons. The first issues are that we need to find a wormhole that can act as a spacetime tunnel for us to our desired location. And if we trust theory suggested by Albert Einstein for same, then these tunnels could be highly unstable, and it may collapse in a very short time. Other than this, its size could be very tiny that may not be useful for use to use it as a tunnel for space travel.

However, these are just some of the opinions and chances are high that someday we will find a wormhole that is stable, big enough to act a tunnel and allows us to travel through it. Also with the help of the advanced research in physics, experts may come up with some ideas to use what we have for those things that we need. And when we will have that expertise, then maybe we will have colonies on distant planets and we will have intergalactic travel to meet our relatives during holidays.
