Our universe, which consists of stars, planets and galaxies, did not once exist. Then a mysterious event gave birth to everything, the Big Bang, but what was there before that? This question has remained a challenge for scientists for centuries. Did the universe begin from a singularity, or did it exist somewhere before? Some theories even suggest the possibility of a multiverse. Today we will understand in simple language what the Big Bang was, what was before it, and how it became the beginning of the entire cosmic journey.

What is Big Bang?

The question of the origin of our universe has always fascinated the human mind. About 13.8 billion years ago, an event occurred which we call the Big Bang. It started from an extremely small, hot and extremely dense point, which scientists call a singularity. From this point time, space and matter were born.

The Big Bang was like an explosion, which started the universe expanding. In the early moments, only tiny particles, such as quarks and gluons, existed. As the universe expanded, these particles started turning into atoms and eventually stars, planets and galaxies came into existence.

What was there before the Big Bang?

Now the question arises that what was there before the Big Bang? Many theories have emerged on this.

singular state theory

Scientists believe that before the Big Bang, the universe was in a singular state. This was the state where all physical laws fail. There was no time, no space, only a point of extreme density.

Cyclic Universe Theory

Another idea is that the universe has been expanding and contracting cyclically. It can be thought of like a balloon, which is inflated and released again and again. After the previous universe contracted, a new Big Bang began.

multiverse theory

This theory tells us that our universe is not alone. Countless universes may exist, each with their own rules and time. Our Big Bang may just be an event that happened somewhere else.

Why did the Big Bang happen?

The answer to this question still remains a challenge for science. Some scientists believe that quantum fluctuations started this process. Small changes of energy took place in empty space, due to which particles and anti-particles were born.

What is cosmic inflation?

Immediately after the Big Bang, the universe expanded extremely rapidly. This is called cosmic inflation. This made the universe uniform and smooth. However, why and how this expansion started remains a mystery even today.

The precious metals (gold, silver, diamond, platinum) and gems on the Earth are considered quite prestigious due to their excessive price. Even though these are rare on our planet, there are many places in the universe, where these gems are found in more quantity than the earth.

From the rare elements present on the moon to the exploitation of asteroids and comets located near the Earth, many people have speculated that man can eventually exploit these resources of space. This can also reduce the cost and time of future space operations. Currently they have been seen only through space telescopes and spectroscopy techniques.

This week will pass through the Earth and Moon asteroid
This week, asteroid 2005 yu55 will pass between the Earth and the Moon. Experts say that this asteroid is unlikely to hit our planet, yet it is being seen as an unlikely source for mining resources. According to NASA’s Jet Propulsion Laboratory, 2005 YU55 is classified as C-type asteroids, usually made of substances such as hydrogen and helium.

Diamond planet discovery
Earlier this year, the discovery of a planet was announced, which is mainly made of carbon and so dense that a large part of it may be made of diamonds. The international team of astronomers who carried out this discovery told Science magazine that they believe that this planet is slightly heavier than Jupiter, but is 20 times more dense.

Diamond is a slightly closer Titan than the planet, which is the largest moon in Saturn and is 1.2 billion to 1.7 billion miles from the Earth. Titan is unique in the solar system for two reasons. It is the only moon that is dense and has stable fluids on its surface and hundreds of lakes have been found on the surface by the Cassini spacecraft.

Where is 20 trillion dollar gold present
Writer John S., in his book Mining the Sky: Untold Riches of the Estteroids, Comities and Planets. Lewis consider deeply on the possibilities of reaching these resources in space. He has highlighted 3554 asteroids called Amun. Under its lower surface, there is a probably 20 trillion dollar gold, $ 8 trillion iron and 6 trillion $ cobalt and 6 trillion dollars platinum.

There is going to be such an incident in the universe, which people will be able to view on the earth too. A small star is going to explode, which people will be able to see from the earth too. This incident happens every 80 years and this is going to happen again after 1946. The name of this star is T Coronae Borealis, which is present in the North Crown Planetarium.

In September last year, SETI’s Astronomer and Unistaler’s cofounder Frank Margis had told by an email that some changes have been seen in the star which is pointing to that it could explode.

T Coronae Borealis is a binary star system an event that occurs every 80 years. Everyone can definitely see this incident once in life. What happens in this that this star is present in the sky but is often not visible, then one day it explods and it is the lingering star of the sky at that time. T Coronae Borealis is three thousand light years away from the earth.

It consists of two stars, one red gound and the other white dwarf. The red gaynt star is getting cold and it is spreading over time. With its aging, many types of things also come out of it. At the same time, the fuel of white dwarf is ending and it is getting cold. White Dwarf takes the material gradually from the red gaynt. It takes the material and eventually it causes thermonuclear explosion one day.

Many research has revealed that now the time of its explosion has come close and this incident can happen on 27 March. According to the American Association of Variable Star Observer, the incident was to be held in 2024, but did not happen. So far this incident took place in the years 1787, 1866 and 1946.
