It seems destined that our universe will have an end, and there are two mainstream views in the scientific community about this end: either a violent collapse or a cold freeze.
With the in-depth discussion of the theory of parallel universes in recent years, some scholars have proposed that there may be a passage to other universes, which may become a ray of life for mankind in the future. Imagine that for the children and grandchildren of the distant future, opening the door to another universe may be the key to their survival. The most pressing question at the moment, however, is whether we can unravel the mysteries of these passages.
A theoretically feasible way to travel through the universe involves wormholes – passages across two universes, like tunnels in a subway system, that take us to another station. Imagine two sheets of paper unfolding in parallel, and the wormhole is the passage in it, a shortcut, a gateway connecting the two universes. This idea was first proposed by Albert Einstein and his disciple Rosen in 1935, who envisioned that the passage of wormholes would allow us to quickly cross to another universe like subway passengers. If the multiverse hypothesis is true, then this channel is viable. This not only shortens the distance between universes, but also opens the door to travel through different universes.
Still, the journey through the wormhole is challenging. First and foremost, the wormhole itself is deadly. When Einstein first introduced wormholes into his equations, he did not consider them as passable passages. However, modern scientists still hold out hope that by passing through the wormhole, they may be able to enter another parallel universe. It's like an elevator button, every time you press it, you reach a new universe.
But there are even bigger challenges that have yet to be solved. Unknown destinations are a big obstacle. You may reach the center of a star, or the core of a planet, and not all of them are suitable for survival. A passage through parallel universes may not be feasible for individuals, but it could still be the path to salvation for all of humanity.
If the channels are as tiny as atoms, then we may need to send seeds, nanobots, carrying DNA and the necessary information to create new life on the other side of the universe. Just like the trees on the earth scatter seeds and give birth to new life. If this idea is realized, it will be possible for a highly developed civilization to use a powerful laser beam to "burn" a channel in the structure of space-time.
Although difficult, physicists have calculated that concentrating huge amounts of energy to a point where Planck energy could form a passage in space-time, like an elevator to another universe. In this way, microcapsules or nanobots carrying the codes of the human universe can transmit hope to another world. In the face of extinction, this may be the last straw for mankind.
The inability to achieve this feat means the ultimate destination of the universe. But if we succeed, our universe will be reborn, like a phoenix nirvana, miraculously reborn. This reminds us that we are playing the role of God. This grand idea is like a "replay key" in the universe, allowing the cosmic concerto of human history to start anew, and we do not yet know whether at least some creatures will almost certainly survive, and whether others will also survive.
