You study the universe and might think that there is nothing new to be discovered in the universe and physics. But the fact is that there are countless unsolved mysteries that exists for so many years. Are the universe ancient mysteries solved now?
Some of the mysteries are is there alien life? what is exactly a universe? What is a black hole? The dark matter, the nature of time, and more. Even though some of the universe mysteries are solved, there is no proper explanation.
Scientists are working with some of the biggest unsolved questions out there, so let us see a few mysteries and find out whether the universe ancient mysteries solved.
Evolution of Universe
The universe may seem to be a strange place, but it is not distant. Outer space is only 62 miles (100 kilometers) away. Simply it is a few dozen miles above your head and 8000 miles (12,800 kilometers) below your feet.
The universe is everything. Some 15 billion years ago, the universe formed from a hot, dense sea of matter and energy. It formed galaxies, stars, planets, and life while the cosmos expanded and cooled.
It includes all the matter and energy that space contains as well as the time, and moreover, YOU. The planets orbit the Sun along with asteroids and comets. Sun is one among the hundreds of billions of stars in the Milky Way galaxy. And most of the stars have their own planets.
The Milky Way is one of the billions of galaxies and is thought to have supermassive black holes at their centers. The stars in all the galaxies and all the other things that astronomers can’t even observe are all part of the universe.
Are the universe ancient mysteries solved?
Let us see a few of the universe ancient mysteries.
What is exactly the time?
Have you ever wondered about unbreaking an already broken egg? The fact is, it is easy for us to break an egg but it is impossible to unbreak the already broken egg. This is because of the arrow of time
We all know that time appears to be in one direction. The past that lies behind us is fixed and unchangeable. The future lies ahead and is not necessarily fixed. Although we can predict it to some extent, there can be no firm evidence or proof for it.
The events we go through cannot be reversed. It appears to be unbelievable to make time travel in the other direction. So this one-way direction is often referred to as the arrow of time and this simply means the passing of time from the past to the future.
But it is a mystery how exactly this phenomenon arises from the microscopic interactions among particles and cells. Why are we stuck with time’s arrow? This is one of the mysteries of the universe that has no proper answer.
There is a property called “entropy” that defines the level of disorder. It only increases, and so there is no way to reverse the increase of entropy. It is a matter of logic and there are more disordered arrangements of particles than ordered arrangements. And so when things change, it falls into a mess.
How did it all begin?
This is one of the universe ancient mysteries solved, but is it the exact reason?
Scientists think the universe began with a bang, which is a big bang. The most widely accepted theory for how the universe started is the big bang theory.
This theory says that more than 13 billion years ago, the universe came into being from a single, unimaginably hot, and dense point. The Universe grew from smaller than a single atom to bigger than a galaxy in a fraction of a second. And it kept on growing at a fantastic rate. Even still, it keeps on expanding.
The reason for standing with this theory is, Big Bang Theory accounts for many things astronomers find through telescopes based on ground and space. It explains the reason why other galaxies are moving away from us as space continues to expand. It accounts for a glow, which is the leftover heat from the universe’s birth and now cooled to a few degrees above absolute zero.
This is a remarkable and Powerful explanation of how the Universe came to be.
Why is there a monster black hole?
There are about 2 trillion galaxies in our universe, and in the heart of every Galaxy, there is a supermassive black hole, weighing almost 50 billion times the mass of the sun. The Unsolved Mystery is how did they get there?
Black holes are described as the yawning voids that hide in deep space while gobbling up anything that comes in their path. They are extremely dense with a strong gravitational attraction where not even light can escape them.
It is formed when a star dies. Continues to compress and creates a stellar black hole. They consume the dust and gas from the surrounding galaxies and keep them growing in size. It is predicted by scientists that there are millions of black holes. But it is not sure what is inside it. Many suspect it to be a singularity which is a region of zero size and infinite density.
It is believed that if you fell into a black hole, gravity will stretch you like spaghetti. Your death would come before you reach the s singularity. A study published suggested that it would act much like a wall of Fire, and it would instantly burn you to death.
Although physicists predict the influence of gravity on sizable objects, it remains a mystery when it comes to minute particles.
Is there a parallel universe?
You might have watched movies that are based on science fiction and yes it would be really interesting. But what if it happens in reality? Shocking right? There are some scientific theories it supported the idea of a parallel universe beyond our own.
This theory remains one of the most controversial theories in science. There are hundreds of billions or trillions of galaxies that spin through space. One popular theory says that the universe is expanding, which means the galaxies far from Earth are moving away from us and it is called cosmic inflation.
As the earth gets further away, the speed of the expansion of the universe gets increases. At some point, the universe expands too fast for light to ever reach us from some very far away galaxies. This means there is a point in the universe that we cannot see past.
That doesn’t mean there is nothing there because there are still more galaxies beyond this edge, but we will never be able to see them. Some physicists describe this edge as a separate, parallel universe. Another thing is, Immediately after the Big Bang, inflation occurred and it happened in multiple places.
This caused separate universe bubbles to inflate, and in some cases, certain types of the matter ended up in one bubble rather than another. This means in some bubbles the physical rules which affect how things work might be different.
These mysterious processes of inflation and the Big Bang Theory have convinced the possibility of the existence of multiple universes.
Could there be another you?
If there is a parallel universe, then would there be another you? This is one of the mysteries of the universe. The way our universe is, and the way we experience it, might not be the only version of events. There are other universes, that might contain a different version of ourselves, histories, and other alternate outcomes. This is one of the most exciting possibilities when it comes to physics but it is far from a certainty.
To be a part of the multiverse, if the universe is compelled to repeat itself, you could find another version of you if you look far enough. In fact, it might be infinite versions of you. Some of your twins will be doing exactly what you’re doing right now, while others would do something different. Moreover, there are chances where they would have chosen a different career and life choices.
It is likely not a one-time event, where the Big Bang gives birth to our universe. The fuel not only generates our Big Bang, but it would also generates countless other Big Bangs each giving rise to its own separate universe.
Evidence is actively searched by the Physicists looking for signatures, hot or cold spots in the cosmic background radiation, the radiation left over from 380,000 years after the Big Bang created our universe.
over the past 20 years, there is proof of this radiation, captured by multiple satellites.
Is there life beyond earth?
The origin of life on Earth may have been inconvincible, but theoretically, there should be other living planets in the universe. There are about 100 billion galaxies each containing tens of billions of stars. Many of these stars have planets, so even if life forms on one planet out of every trillion planets, the number of planets that contains life in the universe will be 1 billion.
Even in our own solar system, a few locations are said to be hospitable to microbial life such as the planet mars, and the subsurface oceans of Europa which is one of Jupiter’s Galilean Moons. The discovery of Martian bacteria would immediately tell astrobiologists that life is extremely common in the Universe.
There’s plenty of evidence that Mars was warmer and wetter in its distant past. If the atmosphere of a planet turns out to contain substantial quantities of oxygen and methane, it’s almost certain it must have living organisms on its surface.
For life to evolve from single-cellular organisms to anything bigger on earth, it took billions of years. So Looking for microbial life might be the best chance of success to find out the existence of life.
Why we have seen no signs of aliens?
This question has been shown in countless films and TV series, books, podcasts, artwork, and conspiracy theories, but in the universe, it remains unanswered.
But there have been plenty of UFO sightings on Earth. It is considered that aliens spread throughout our Milky Way and it is considered reproducing on themselves. It is concluded that even at modest speeds of travel, every star in the Galaxy would be visited in a fraction of the age of the Milky Way.
It is believed to be that aliens should be here on Earth and they do not appear to be, and so-called a paradox. Hundreds of explanations have been proposed and the idea is that we are the first intelligence to arise in the Galaxy and so are totally alone.
A possibility is that there is no paradox because signs of visitation in the distant past would be erased by wind, rain, and geological processes.
There remains the question of why we have seen no sign of aliens in our Galaxy, even after searching with telescopes for more than half a century. However, it is said that there is no mystery, yet the reality is hard to find out.
How will the Universe end?
It is believed that the Universe started with the Big Bang theory. But is there an end for the universe? Theorists have concluded the fate of the universe based on a number of factors. It is believed that the fate of the universe could take one of several wildly different forms.
If the amount of dark energy is not enough to withstand the compressing force of gravity, the universe would get collapsed into a singular point which is known as the Big crunch, a mirror image of the Big Bang.
Recent findings indicate that Big Crunch is less likely than Big Chill in which the dark energy forces the universe into a slow and gradual expansion and all the remains would be the burned-out stars and dead planets that hang around at temperatures that are above zero.
A big Rip scenario could occur, if enough dark energy is present to overwhelm all other forces where all galaxies, stars, and atoms would be torn apart.
