Our universe is expanding since the beginning. It is expanding at high speed and everything comes under this universe. Even science hasn’t detected its edge yet. We, humans, haven’t figured out yet the starting and ending point of it scientifically. Because of its vastness of it and lack of highly optimized technology we are still unable to detect the actual edge of the universe. Seeing the universe from the perspective is very near to the fact and satisfies our logic. There are many theories postulated about the existence of the universe.
Everything around us that can be seen or unseen is all part of the universe. From the microscopic level to the big planets, stars, and galaxies, all come into it. Finding out the facts and the mysterious places of the universe is an amazing job and shocking too. The universe has supermassive black holes, stars, planets, and several other things. We are still unsure about the principles like the Parallel Universe or theories of the Multiverse. These principles may be right in the darkness and deepness of the world.
Here are some amazing facts that you should know about the universe. They are very interesting to know and shocking too.
#1. We can only see the 5% of the Universe

For the past 350 years, scientists have been analyzing the universe. They say that all we can see is just a tiny part of the universe. This discovery shocked scientists and all humanity. There is only around 4.9% of the mass energy formed by atoms. This includes you, me, galaxies, stars, and planets around us.
According to scientists, 27% of dark matter is invisible which is a part of a mass of cosmic energy. Dark Energy and Dark Matter occupy a lot of space that we can’t measure with our currently developed technologies. There is around 68% of dark energy in the dark matter which comes as the mass-energy of the vast universe.
It is hiddenly expanding and accelerating in space. It is also called cosmic expansion. Quantum theory studies in a more deep and shuttle way.
#2. In its core, every galaxy contains a large black hole

With the result of quasars in 1963, it became clear that the light comes from the central region of the solar system and not from the stars. Active galaxies are blowing up hundreds of times more than a common galaxy. The mind can only think of the energy about 50 billion times of the mass of the Sun that rotates around the supermassive back hole.
Supermassive black holes are not an exception, despite that the active galaxies report only about 1% which was discovered by NASA’s biggest Hubble Space Telescope in the 1990s.
Each galaxy has its back hole. At least one for sure. Our native galaxy Milky Way also has at least one hole. They might be closed or dead because of the lack of their food supply chain. There are some uncovered questions in the term of back holes like what exactly they doing in the center of galaxies? or did new galaxies create them? etc.
#3. The universe contains similar temperatures in all the places
Cosmic Microwave Background’s snapshot shows very shuttle temperature movement that communicates with different densities and regions. The heat that was left from the time of the Big Bang is measured by the Planck Telescope. According to the big bang, it was enclosed as a fireball in the Universe. It can’t go anywhere because there is nowhere so we can experience it around us now. The interesting thing is that its temperature is – 270°C all around.
#4. It was born
Scientists say that our universe was born nearly 14 billion years ago. All the space, energy, matter, and even time were exploded in the largest fireball that is also known as Big Bang.
When briefing the Big Bang Theory it was all started to expand and unlimited galaxies began to exist from the coolest point. It formed huge islands of stars. Our Milky Way galaxy comes among the estimation of 2 trillion galaxies.
All the proof shows that it was popped into existence from an empty point of nothing. What if we ask what was happened before Big Bang? Its answer is probably nothing and It is better to close this query here otherwise you will waste your whole life imagining about it.
#5. There is revolting gravity in the Universe

We already said that our world is expanding from the early point and its separated parts are floating all over space as galaxies and other skymass. The same force is controlling the gravity which works similar to a web of elastic or spring between multiple galaxies.
Kicking off all the expectations, astronomers detected that the universe is expanding at a very fast speed in 1998. They put forward a kind of invisible matter, to explain it and that became dark energy. It has revolting gravity as well as it covers space. That revolting gravity is encouraging cosmic expansion. Almost tow third of the mass-energy stays in the universe.
#6. Sun is creating only a 3rd of the neutrinos
Around 100 billion neutrinos pass every second, which is the derivative of sunlight. It is creating nuclear reactions. Ray Davis, an American chemist, hoped to confirm the standard image of the Sun by just setting out 100,000 gallons of fluid to detect them. Alternatively, he found on a 3rd of the predicted neutrinos. This discovery made him win Nobel Prize. Neutrinos are the very shuttle subatomic particles that exist in a strange quantum superposition like a ghost. These neutrinos behave differently at the same time.
#7. We are alone in the universe yet
According to science, there are about 100,000,000,000,000,000,000,000 stars in this universe and the number of plants may be more than that because even our solar system has one star and 9 planets. In this boundlessness, we have only access to Earth where life exists in human form. Although there are many searches on intelligent signals, there is still no sign for any extraterrestrial life yet found. There might be big possibilities in this vastness of the universe but for now, it is sure that we are alone in the universe.
