6 Crazy Facts about The Universe World Doesn’t Know

The universe is certainly a strange place… perhaps more strange than we know! Throughout the history, humans have been trying to figure it out. If you want facts about the Universe that will blow your mind, you don’t need to look very far. All of its ordinary matters, all the particles that make us and everything we can see only make up 4% of its matter. In 1998, we only discovered the Universe’s major mass component, the thing that makes up 70% of it.

 

Black Hole

A black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape from it. Active galaxies often throw out 100 times more than a normal galaxy. In 1963 discovery of quasars, it was clear that the light comes not from stars but from a central region smaller than the Solar System. The only conceivable energy source is matter, that heated to incandescence as its swirls down onto a giant black hole up to 50 billion times the mass of the Sun. Quantum field theory predicts that, event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass.

 

Blue Planet

The Hubble Space Telescope found that the planet HD 189733b looks like deep blue, but it’s not because of ocean. The blue color comes from a really hot atmosphere about 2,000 degrees Fahrenheit, where special particles melt and form glass “raindrops” that scatter more blue light than red light. In 2005 discovered, this planet is super close to its parent star, only 2.9 million miles away. It’s so close that one side always faces the star and the other side always in dark. Since the planet is 63 light-years from Earth, someone visiting would see many of the same stars we see at night, although the patterns of constellations would be different.

 

95% Area of Universe is Invisible

Only 4.9% of the mass-energy in the Universe is atoms. About 26.8% of cosmic mass-energy is invisible dark matter, revealed because it tugs with its gravity on visible stuff. Candidates for what makes up dark matter include hitherto unknown subatomic particles and black holes made in the Big Bang. But, in addition to dark matter there is dark energy, accounting for 68.3% of the mass-energy in the Universe. It’s invisible, fills all of the spaces and is accelerating cosmic expansion. Our best theory, quantum theory, overestimates its energy density by a factor of one followed by 120 zeroes.

 

The Universe is Like Human Brain

Human brain has a billion neurons and a quadrillion connections, but we still don’t understand how this amazing organic supercomputer really works. Even the scientists recently studied how the big universe with its galaxies compares to the tiny human brain with its cells. A fascinating discovery from the study, it was viewing the brain’s neural network like its own little universe, made up of around 69 billion neurons. Just for the comparison, the observable universe consists of a network of at least 100 billion galaxies.

 

The Universe was born

13.82 billion years ago all the matters, energy, space – and even time – erupted into being in a titanic fireball, is called the Big Bang. The fireball began expanding, out of the cooling debris, there eventually congealed the galaxies – great islands of the stars of which our Milky Way is one among an estimated two trillion. Whatever way you look at it, the idea that the Universe popped into existence out of a nothing, that there was a day without a yesterday. The reluctance to face this awkward question is why most of the scientists had to be dragged kicking and screaming to accept the idea of the Big Bang.

 

Moon is Actually an Illusion

Did you ever notice that when the Moon’s right on the horizon, it looks closer and bigger? It’s called Ponzo illusion. The Ponzo illusion was first demonstrated by an Italian psychologist Mario Ponzo in 1913. He explained that our minds judge an object’s size based around our surroundings. Ponzo illustrated this by drawing two identical lines across a pair of converging lines, resembling railway tracks. This happened because of our brains interpreted the converging sides as the parallel lines moving into the distance.
