What is faster than the speed of light?

What is a wormhole that can reach the edge of the universe in an instant? According to Einstein's theory, the speed of light, which is about 300,000 kilometers per second, is the limit of speed in our universe, and no matter how much mass can reach the speed of light, it can only be infinitely close to the speed of light, which means that all of our technology is limited to the speed of light. The development of the upper limit, that is, the spacecraft we have made, no matter how fast can not reach the speed of light, and the inability to reach the speed of light has given rise to a new problem - interstellar travel.

According to modern astronomical observations, our universe is a vast space, we live in the solar system is one light year in diameter, the diameter of the Milky Way is 120,000 light years, Andromeda galaxy is about 2.54 million light years away from us, the diameter of the observable universe is 93 billion light years, which means that even if we can reach the speed of light, we out of the Milky Way galaxy will take at least 120,000 years, fly to Andromeda galaxy This means that even if we could reach the speed of light, it would take us at least 120,000 years to get out of the Milky Way, 2.54 million years to fly to Andromeda, and 46.5 billion years to fly out of the observable universe.

The human life span is only about 80 years, so our astronauts can hardly fly out of the galaxy in their lifetime, so since we can not exceed the speed of light, does it mean we are trapped within the galaxy forever? Of course not, Einstein, for us to achieve distant interstellar voyages, deduced another premise in the theory, that is, wormholes, the concept of wormholes was first clearly proposed in 1916 by the Austrian scientist Ludwig Elem, and assumed by Einstein and others in the study of the gravitational field equations.

Therefore, wormholes are also known as Einstein Rose Bridge. In simple terms, a wormhole is a shortcut in interstellar travel that can connect two different spacetime to some extent, thus enabling a journey in a flash that we cannot reach in normal space. Take the Andromeda Galaxy as an example, it is about two and a half million light years away from us humans. For us humans to reach the Andromeda Galaxy at the speed of light from Earth, it would take about two and a half million years, about 25 years per generation, so human astronauts would have bred at least one million generations by the time they reach the Andromeda Galaxy from Earth.

If there were a wormhole connecting Earth to one of the habitable planets in the Andromeda Galaxy, perhaps we would need less than a second to cross this distance of 2.54 million light years, so does a wormhole exist? And how does it come about? The wormhole argument was first born in the research and analysis of the Swastika solution, scientists in the process of in-depth analysis of the white hole solution, by Albert Einstein's thought experiment, found that the cosmic space-time itself can also be not flat, uneven cosmic space-time, this type of structure represents a part of the black hole world will be closely combined with another 1 part of the cosmic space.

Wormholes connect black holes and white holes, the passing matter between black holes and white holes, where the wormhole becomes an Einstein Rose bridge, matter at the singularity of the black hole is disintegrated into elementary particles, and then passed through this wormhole to the white hole, while being radiated out, of course, more common practice, wormholes are the product of strong gravity, can produce such a strong gravitational force of the object, must be Black holes, galaxies or quasars. The strong gravitational force they generate creates a great spacetime vortex around itself, and these spacetime vortexes will collide together in a certain situation and create a channel of some sort.

This channel connects two distant regions and eventually becomes a wormhole that can span space, if so, why have we not yet discovered the existence of wormholes? In fact, from the current point of view, wormholes also exist only in the theoretical channel, it is similar to black holes and white holes, basically are the theoretical basis for Einstein's gravitational field theory to get, it can even be said that the solution of this equation is regarded as Einstein's prophecy.

However, so far, only black holes have been confirmed to be real in our universe, and mankind has taken the first photo of a black hole in 2019. Although a black hole can swallow all light, we can still photograph it using the light rubbed out by the accretion disk around it. White holes and wormholes are still theoretical premises, they have not been observed by humans, so there is still a lot of controversy in the human world about wormholes, how they are created and what kind of structure they have.

If we step into a wormhole, what will happen to us? Up to now is unknown, but the emergence of the wormhole theory has given many scientists great hope, because only through the existence of wormholes, we can cross the vast river of stars, to be able to truly realize the meaning of interstellar travel. However, it is certain that if the wormhole exists, then we want to enter it is not easy, because it is filled with a very strong gravitational force, even enough to bend our space-time.

Also, it is likely to be very unstable and a great test for our spacecraft. However, certainly, the speed of light cannot be surpassed and if we cannot find a similar interstellar travel path like a wormhole, when the Sun becomes a red giant in the future, our Earth will also be swallowed up and the whole planet will cease to exist.

The nearest star system is 4.22 light-years away, and it would take nearly 10,000 years to get there, even with the fastest spacecraft available. Therefore, the possibility of intergalactic travel determines the success or failure of our human race to reproduce forever, knowing that, without becoming a true interstellar race, we are forever bound to this azure world, and will follow its birth and die together.
