Which are the most popular scientific theories in the world? In our collective knowledge, we might think that we have uncovered most of the universe’s mysteries. Unfortunately, we do not have enough knowledge to fully comprehend everything. Now and then, we come across a new theory that completely upends everything we have ever known. Somehow, it holds the key to our unanswered questions. Sometimes the most outrageous theories have been proven to be true, not just as long as more discoveries are made and certain pieces of the puzzle fall into place, but even as the wildest theories become more accepted over time.
1. Theories of the Ekpyrotic Universe
According to the ekpyrotic universe theory, instead of our universe having originated from a singularity as in the Big Bang theory, our universe is comprised of two universes that collided. We believe that this collision resulted in a “resetting” of our universe and that after that point it began to expand just like it did at the Big Bang. In the theory, however, the universe will eventually contract rather than infinitely expanding, resulting in the Big Crunch, referred to by some physicists.
2. White Hole Existence
The powerful gravitational pull of black holes creates a vacuum that absorbs all matter and light. Where are the white holes? It’s the opposite of a black hole because they spit matter out rather than sucking it in. There have never been any observations of white holes (probably because they would only exist in extremely hypothetical scenarios), so it’s uncertain whether a white hole would function as the tail end of a black hole, a wormhole, or something else entirely. When the matter is spewing out of a white hole, the matter must somehow avoid merging with a black hole and sustain itself.
3. Paradox of Fermi
As originally proposed by Enrico Fermi and Michael H. Hart, the Fermi Paradox asserts that our Milky Way galaxy must contain millions of intelligent species, and therefore we should have picked up some signal about one of them by now if the Drake Equation is correct. The Great Silence refers to this debate.
Since the Great Silence began, several intriguing theories have emerged to explain it. The most intriguing and imaginative one suggests that we live our lives in a Matrix-like simulation.
4. An Overview of Simulation Theory
The theory holds that we all live in a computer simulation that was created by aliens in a distant galaxy. In addition to believing Simulation Theory can be proven, several prominent physicists and scientists are working on experiments to prove it. The simulation of our universe is being created by a German team of physicists, in particular.
5. The Universe is a Hologram-Scientific Theories in the World
We might be looking at a hologram of the universe created by the universe itself, according to this theory. Stars and galaxies visible in the night sky are similar to a picture we see on a wall as we lookup. Holographic principles could explain why the universe appears fragile when broken down to its most basic energy scales.
6. A black hole can give birth to an entirely new universe
Black holes are undoubtedly the dark reapers of the universe, due to their mysterious nature and capacity for consuming light. According to this theory, a black hole may be the mother of the universe. An intense gravitational force pulls matter into a black hole, but the dense matter is so compressed that it gets spit out again, forming a new universe from the original one.
7. The Many Worlds Theory-Scientific Theories in the World
There are countless parallel universes, as evidenced by the many-worlds theory. This proves that space has an objective reality. Nevertheless, the point of singularity cannot derived from condensed matter. Instead of new universes arising from black holes spontaneously, the many-worlds theory proposes that every time we make a decision, a new universe is born.
8. The Universe’s Heat Death
In this theory, thermodynamics is adopted. To being infinite, the universe should be infinitely old. In this case, the universe will remain stagnant on account of the same uniform temperature pervasive in an infinitely old universe. For this to make sense, however, the speed of expansion must remain constant throughout time. Another idea, such as cosmic inflation, is directly at odds with this one.
9. It is murder to observe dark energy
According to theoretical physicist Lawrence Krauss, every time we study dark energy we are killing the universe. Dark energy makes up an estimated 70 percent of all the energy in the universe, according to physicists. Many of the unexplained peculiarities of deep space can be explained by it as well.
Unitiated by the decay of an unusually high amount of energy into zero energy that repelled gravity. In our universe, the process of going from a false to an ordinary vacuum led to its creation. The quantum Zeno effect is a term from quantum mechanics.
10. The Panspermia Theory-Scientific Theories in the World
The Greek word panspermia means “seeds everywhere”. According to panspermia, there are seeds of life in every part of the universe. Natural processes might allow seeds to move from planet to planet or even galaxies to galaxies.
Recently, several extremophiles were discovered on Earth, lending credibility to this theory. The life we know can survive extreme conditions. Stowing away on an interstellar comet or meteor might expose an organism to any number of conditions.
