6 sci-fi concepts that can be real – the clare people

This effect, known as time dilation, has been proven by NASA, and it didn’t even have to go very far – just a probe in our planet’s orbit. In 2004, the Gravity Probe B spacecraft, specially designed to test Einstein’s theory, proved that the rotating planet’s gravity literally pulls the fabric of space-time around it, creating an effect of ” drag ”, which results in different times in the orbit and the surface. clocks.

Because of this small difference (milliseconds per day) between the passage of time on the Earth’s surface and in its orbit, scientists have had to adjust the clocks of GPS satellites, which are always a little ahead of our own. If the GPS had not integrated the theory of relativity into its technology, the maps of our smartphones would guide us miles away from the right route.

But would we be able to extrapolate this concept to time travel? Some scientists believe it and strive to prove it. The stronger the gravity, the slower time will be, and vice versa. If you can bend the space as you like, there is the possibility of bending the time. And if we warp time in a loop, it is possible to travel from the future to the past, then to the future (no pun intended for a certain film trilogy).

A conceptual project for a time machine was published in 1974 by physicist Frank Tipler. Dubbed the Tipler cylinder, it is expected to be large, about 60 miles long, and extremely dense, with a mass comparable to that of the Sun. It must therefore turn fast enough to distort the space. time until the moment when time folds in on itself. Perhaps the complexity of this proposal deters some potential time travelers, but the concept would work, at least on the tip of a pencil.

Parallel universes

There are many scientific concepts that address the possibility of existing and not just ours. the universe, but many others, each with its own version of Earth (or not). One of the areas exploring this field is quantum mechanics, but it is important to remember that it all depends on how quantum laws are interpreted.

One interpretation is that many parallel worlds are constantly separating from each other at every moment. This idea was formulated by Hugh Everett to explain some non-deterministic processes important to quantum mechanics, and many different versions of this “many worlds” hypothesis emerged later, but with the same key concepts.

Imagine a fox trying to catch the grapes, like in the famous fable, but cannot reach the branches of the tree. Refusing to admit failure, the fox turns around and says the grapes didn’t look so tasty and walks away. However, this decision has implications, according to theories such as Heisenberg’s Uncertainty Principle and Schrödinger’s Cat in the Box.

The result, to sum up, is that the fox’s decision triggered a series of different decisions. This results in the “creation” of other worlds in which the fox has adopted a different attitude. So, there are a number of possibilities for the end of the story, and each possibility generates a world totally separate from ours, hidden and inaccessible – unless someone finds a way to open a passage.

Multiverse

With so many possibilities for parallel worlds, scientists speculate that the infinite set of “child worlds” (those overlapping realities that divide into parallel worlds) results in what is called a “multiverse.” Infinite universes are a consequence of the scientific theories reported above, so it may be that more than one proposition for these universes is correct.

There are also many possibilities for this set of universes. They can be like ours, but with different details, or they can be governed by other physical laws. For example, the Big Bang in other universes could have happened in other ways, resulting in other initial configurations for the formation of these universes.

This was the theme of Stephen Hawking’s latest work. With the theorist Thomas Hertog, he published an article which tries to prove that it is possible to observe the cosmos and to find evidence of these previously inaccessible places.

Teleportation

This is perhaps the most improbable of the “realistic” concepts in science fiction. We won’t say this is impossible, as some argue that quantum mechanics allows quantum teleportation, in which the quantum state of one particle (a) would be copied into another particle (b), regardless of the distance . But, you may have noticed by now, there are several issues if we try to apply this concept to the world on a large scale.

The first problem is that the quantum teleportation destroys the quantum state of the “a” particle, so it really looks like it was transported from one place to another. The big question (which is even philosophical) is: has particle “b” become particle “a”? If the answer is yes, what happens to the “essence” of particle “b”? teleported to another location, have all subatomic particles in your body copy to other particles at the target location. If this is the case, there is a possibility that your body will be rebuilt, as the information (configurations) of the particles is never lost due to the entropy of the universe. But is the person arriving at the destination really you?

There is a philosophical paradox here. Suppose you have a boat stuck at the dock but haven’t used it for a long time. It suffered a lot of rain and bad weather and started to deteriorate. So, you hire people to gradually change the wood of the structure. Within a year all the wood has been replaced and your boat is brand new. The question is: is it the same boat? Teleporting will you get to the target location, or will it be someone else, a clone, while you vanish? Finally, would your clone have the same consciousness, the same personality and the same memories as you?
