Our universe is full of mysteries that science has yet to come up with a satisfactory explanation for.
1. Black Hole
A black hole – the “blackest” entity in the universe – is an entity that contains a lot of interesting things. A black hole can be compared to a cosmic quicksand. They are formed when a star is destroyed, exploding inward with great gravity (which can even suck the surrounding light in).
For that reason, it’s almost impossible to see a black hole with the naked eye. Black holes are also “invisible” to telescopes that emit electromagnetic waves, X-rays, and ordinary light.
We still have questions surrounding black holes. Like, what is a real black hole? Or how black holes work? All we know about it, is merely limited to the outer region. Just know that once you get in, you won’t be able to get out.
2. “The Giant Void”
In contrast to the intrinsically black hole, we have “The Giant Void”. This place is a void, strangely empty, with both “dark” matter and matter. Light can also pass through, and according to scientists’ estimates, there is “dark energy”.
According to statistics, The Giant Void is the second largest “space” (1.3 billion light years) in the universe.
3. Dark matter
Dark matter – Dark Matter – is still a mystery that causes headaches for all of humanity. Approximately 27% of the universe is made up of this kind of matter. That’s the mystery, but we’re using “dark matter” to explain other phenomena occurring in the universe.
There are few things we can be sure of it. First, it’s really dark, which means it can’t be the building blocks of planets. Second, it’s not “antimatter”. And finally, it’s not constructed in its usual form.
But, to further study the nature of “dark matter”, scientists will have to spend a lot of time.
4. Dark energy
Besides 27% dark matter, we also have 68% of the entire universe made up of Dark Energy – Dark Energy. All the ordinary energy that we know about is only 5%.
And like dark energy, we still don’t know much about dark matter, except for the hypothesis that it is behind the expansion of the universe.Everything we imagine about dark energy, as well as dark matter, comes from a concept called the “cosmic microwave background”. The CMB was just a moment in thermal radiation that lasted until 380,000 years after the Big Bang, when the first hydrogen atom was formed.
5. Huge attraction
Something really “suck” away 220 million light years, and it “pulled” our whole galaxy towards it.
Since the time of the Big Bang, our universe has been constantly expanding, so it is quite possible that our galaxy has shifted.
They called it an anomaly, and named it “The Great Attractor”. The researchers used the theory of dark matter to explain this phenomenon. Another theory is that our own galaxy – the “Milky Way” – is preventing humanity from seeing something that is pulling us at 1.4 million miles per hour.
6. The mysterious moon of Saturn – “Peggy”
Saturn (Saturn) once had a satellite, a small moon named “Peggy”. “Peggy” was discovered by NASA experts in 2013.Numbers, in 2013, NASA’s Cassini telescope captured images of Saturn’s rings. And they were surprised to discover that a new form of “moon” was being formed. The discovery also helps explain how more than 67 other moons of Saturn formed.But in a public press conference, NASA staff gave the status line: “This object will not be able to grow any more, and may even be broken into many pieces.” Still no more information about Peggy.
7. KIC 8462452 – “Tabby’s Star”
KIC 8462452 – also known as “Tabby’s Star” – is a star with many anomalies 1,500 light-years away.
First, there was something unidentified, blocking in front of 8462452, and the amount of light it emitted was blocked by 20%. This is really surprising, when a planet as large as Jupiter can only block … 1% of the light of KIC 8462452.
There are studies suggesting that it is a Dyson Swarm, a less complete form of the Dyson Sphere structure, surrounding the host star and sucking all its energy from it. But so far, there is no definite confirmation yet.
