The Journey To The Edge Of The Universe-Observable Universe 2022

The Journey To The Edge Of The Universe: From the beginning of human history, we have repeatedly looked at the sky and been amazed. With the help of our forefathers’ hypotheses and modern science, we have come to know where our place is in this whole universe, but the journey to know ourselves and our place has been a long one. There was a time in our history when people considered the earth to be the center of this universe.

The Journey To The Edge Of The Universe

And everyone assumed that the sun and other planets and stars all revolved around the earth, and anyone who questioned this belief would be severely punished because people in the West thought that questioning this decision meant challenging God. But in time, the truth comes out in front of everyone. Gradually, with the advancement of technology, everyone can understand what the real truth is.

Let’s go on a short journey, in which we will try to make this Univers in such a way that we can go from our home to the end of the universe.

Earth is the only planet where life is possible according to our knowledge. Let’s start with the nearest satellite to where there is nothing like the earth, there is no liquid water, and there is no atmosphere therefore life does not exist here. It is known that Chad originated about four and a half billion years ago when a planet like Mars collided with Earth.

Our sun is the largest source of energy in our solar system, and all the animals on earth have been able to survive because of the sun. All the planets and satellites in the solar system are orbiting the Sun in their proper place and in the orbit due to the force of the Sun’s strong gravitational ball.

The Journey To The Edge Of The Universe

The closest of these planets to the Sun is Mercury, filled with large craters around the surface of Mercury. From a distance, Earth looks a lot like the moon. So far two spacecraft have been able to go to the one is Mariner 10 and the other is MESSENGER. MESSENGER Pro sent high-quality images of Mercury to Earth in January 2008. These satellites have also been able to map about fifty percent of Mercury’s area, but it has not yet been possible to map the rest of the space due to the extra light and radiation due to its close proximity to the Sun.

After that, we will go to Venus. The size and gravitational force of this planet are much the same as that of Earth. This is why we cannot see the planet’s surface through a telescope because it is surrounded by acid clouds. The surface of Venus is filled with millions of small and large volcanoes, with so many volcanoes that in about 100 square kilometers you will see 150 large volcanoes, with no atmospheric clouds but no rain on Venus.

Although there is a possibility of acid rain a few kilometers above the surface. But that acid evaporates within 25 kilometers of the rain coming to Venus’s page. Researchers have estimated that the planet had water billions of years ago that slowly evaporated over time, with no life on Venus, but scientists believe that the planet has a place to live between the upper cloud layer and the lower cloud layer. That is why I have not lost the race of life yet.

The Journey To The Edge Of The Universe

The next station in our city is Mars. From the research of all the spacecraft sent from Mariner 4 to 1965 so far, we know that the other planets in the solar system except Mars don’t have can be water or life. Scientists view Mars, billions of kilometers away from Earth, in such a way that humans may one day be able to make their home on Mars.

Asteroid belt

After some distance from Mars, we find the Asteroid belt. The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars.

The largest planet in our solar system Jupiter has four large satellites and more than a dozen smaller satellites, so large that it would seem as if the planet itself is a solar system, even if all the planets in the solar system could be brought together in one place, they would not all weigh the same as Jupiter. Above it is the Great Red Spot which was created due to a terrible storm. Not only that, the Great Red Spot is almost three times larger than our Earth. It is estimated that this storm on Jupiter has been going on for about 300 and a half years.

The next planet is Saturn, the most beautiful and fascinating planet in our solar system, surrounded by a royal ring. This ring is made up of tiny Astroied and ice particles. There are about 62 satellites orbiting Saturn. Titan is the largest and most interesting because Titan has an atmosphere. Titan is the only satellite in the solar system to have an atmosphere.

When we leave Saturn, we will find Uranus Neptune. The outermost planets in the solar system that was beyond our knowledge in the past, and we discovered them after the discovery of the telescope. Outside of Uranus and Neptune is the Kuiper belt, which is about twenty times wider than the aforementioned asteroid belt.

Edge of the Universe

These Kuiper belts are made of different types of astronomical materials. These are mainly made of methane ice and ammonia, and on closer inspection, it looks like an unknown world made of small ice. Which floats freely in space. And PLUTO is one of them.

Leaving PLUTO, we will see Voyager 1, the greatest spacecraft in human history. Which has gone far beyond its own 40-year journey to the solar system. Voyager 1 is about 19 billion kilometers away from us. It is a man-made spacecraft that has given us the most information about the solar system and space.

Edge of the Universe

But now let’s go further. We are now in a place where our solar system is almost gone and from here our sun looks like a normal star. We are so far away from the sun now that it would take about a year for sunlight to reach this point, but surprisingly the effect of the sun’s gravitational ball is not over here, A comet or a cloud of comments surrounds our solar system from this place which we call the Oort Cloud.

The Oort Cloud is an extended shell of icy objects that exist in the outermost reaches of the solar system. so we don’t have the exact information about whether the off-cloud is true yet. It is assumed that this cloud is at the very edge of our Sun’s gravitational ball, then the effect of the Sun’s pull is no longer there. Our solar system ends here, but our journey is not over yet.

Then our journey is going to be more exciting. Now we are going through a place filled with complete darkness where we cannot see anything with the naked eye. We need infrared vision to see here. If we look at infrared, we will see some more amazing things in this place. These are Rogue planets. There are no stars on the moon, There are no stars. 

These planets are like family members who were lost at birth to their siblings. These planets may be covered with a thick sheet of ice, but there may be large seas of water in the center. And maybe in all these big seas life has survived in some other form. This time we are all near the next station. 

From here we are trying to see our Milky Way galaxy from a distance. All the small bright dots to see from here get bigger one by one. When we see this thrilling scene from here, we really realize how much power we have, we live at a small point 30,000 light-years away from the center of the Milky Way galaxy. But from here we can see our neighboring Andromeda Galaxy.

Edge of the Universe

Observable Universe

Scientists speculate that our galaxy means the Milky Way galaxy and the Andromeda galaxy are moving very fast towards each other. And about four billion years from now, they will collide with each other. Small and large galaxies come together to form a group. There are so many galaxies in a local group that we can’t even recognize our Milky Way, and you’ll be even more surprised if you wonder.

That billion of such local groups combine to form a supercluster so that a supercluster can see the local group, a local group can have billions of galaxies, and a galaxy can contain billions of stars with planets that have planets, Doesn’t it seem that life exists somewhere outside of Earth, even though we are so far away now? The tiny dots we see from here are a galaxy in itself.

But it’s just that we have no idea how big our observable universe is. So what comes here is all our information all the information ends everything. There are those who think that this observable universe is like a floating point in the ocean and that there is a possibility of more such universes in space.

We have the potential to be about 10 million superstars in a small universe. Together we can call it our Universe, and here we have all the information of our science before we can see it and we can’t make any guesses and that’s why we call it Observation. 

There is no end to this theory we call multiverse but it is just a guess and this guess can be wrong, after knowing about this great universe do you feel very small, as if we have no existence in this great universe and We have no power? But our thoughts are not small but imagine once we had space as far as humans could see when the periscope was not invented.

But the present has changed. In the last few centuries, we have learned a lot and we will discover new things even before that. It may be impossible to break the time limit but we can increase the limit of science now which we can’t even imagine 100 years later it will become a reality maybe we will discover more new information about the universe. 


Q. Why can we see 46 billion light-years?

A. If the Universe had no dark energy in it at all, the farthest objects — stars, galaxies, the leftover glow from the Big Bang, etc. … But in a Universe with dark energy, that gets pushed out to an even greater number: 46 billion light-years for the observed dark energy our cosmos possesses.

Q. How was the universe created?

A. Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

Q. How cold is it in space?

A. Far outside our solar system and out past the distant reaches of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).
