The universe is huge - so huge that even if you know approximate numbers about its size, it’s still impossible to imagine how big it is. Even if you try to imagine it, you'll risk drowning in an ocean of zeros.
However, that's why the universe never ceases to amaze us with its beauty and mysteries. Even with modern computers, telescopes, vehicles and many years of research, we still can't fathom the universe as a whole. This is amazing, because it means there are lots of interesting things to hear in the future.
Some of these things will shock us, some will help us advance and others could even scare us. It’s better to know than to reject truth and face challenges unprepared, right?
To learn as much as we can, professional astrologists work many hours per day to discover new things about the universe by measuring changes, doing analysis and comparing data. And while it seems to be hard mental work, it pays off because it helps to learn about what decisions humanity should make to advance further and avoid unexpected problems like meteorite strikes that would cause lots of damage.
Still, you shouldn’t worry about what harm might come. Instead, read these insane, breathtaking facts about the universe.
10 Your Body Is Made Out Of Stars
You and almost every other body in the universe are made out of stars; more precisely, dead stars. At the beginning of the universe there were only simple elements like hydrogen and helium. Later these elements combined and formed the first stars that, because of heat and gravity, combined hydrogen and helium into heavier elements like iron and gold. After some time, the first stars died and through their explosions created new elements.
Your body has almost all elements in the universe. Of course, some like oxygen and hydrogen make a bigger part of your body, but your body also contains small amounts of elements such as gold!
9 When You Look Into The Sky, You’re Looking Back In Time
The stars you see in the sky aren’t stars, they are the light starts sent out a long time ago. Let me explain: stats are bodies that emit light, so everything you can see is their light, not their bodies. Because light takes a certain time to reach you, you see how it looked some time ago.
One light year is a distance that light travels in one year. So, if a star is 1,000 light years away, you see how the star looked 1,000 years ago!
8 Scientists Have Been Looking For Extraterrestrials
Not only astrologists but also biologists and physicists are interested in finding life in space because it not only would allow us to learn more science, but also stay informed about what should we do in the future; prepare for possible alien attacks or help each other to advance.
Scientists are so passionate about this subject that they created dozens of interesting techniques on how to find them. For example SETI (Search For Extrateriastrial Intelligence), who are leading in alien research studies, use their methods to look for cosmic rubbish, nearby stars, artificial bodies, radio waves and radiation to make alien discovery a faster deal.
7 There Are At Least 10 Billion Trillion Stars In The Universe
While scientists can’t agree on the exact number of the stars, 10 billion trillion stars could be the most reliable number we have. Every star is different in size and can be hundreds of times smaller or bigger than our Sun. Furthermore, every star has surrounding bodies like planets that in every solar system are found from four to 12.
Stars emanate heat and light, which is believed to be one of the primary sources of energy in planets living organisms should use. To satisfy your curiosity, imagine that if as little as 1% of stars out there could create conditions suitable for life, then we would have lots of alien species to meet.
6 Scientists Think That We Could Be Extraterrestrials
While there is a huge interest in finding aliens, we could be aliens as well! Some scientists believe that the simple microorganisms like bacteria originated on Mars and later due to meteorite strikes traveled to the early days of planet Earth.
From there we further developed into more complex organisms, and after many years evolved into the human beings we are now. Sounds crazy, yeah? But the thing is that at that time, the Martian atmosphere could have been more suitable to life. This means there's a chance that we and many other species we know are aliens who colonized the planet we live now.
5 There Could Be More Universes
Yep, our universe may only be one of countless others that are completely different from our own. Tiny changes in scientific principles could make other universes into something we couldn’t even dream about.
It’s due to the simple fact that if the big bang, from which astrologists believe our universe started, can explode in many different places. If that's the case, then there could be an uncountable amount of other worlds.
4 Black Holes Also Die
If you haven't heard before, black holes are objects of varying sizes that we can’t see. Because of their super strong gravity, light can't escape a black hole's pull, and they feed on the light they catch to live longer.
Yet, leading physician Stephen Hawking tells that if black holes go for too long without "eating," and evaporate too fast, they can die off after some time.
3 The Universe Grows
Before the 1920s, people thought the universe to be static, but astronomer Edwin Hubble discovered that the universe is expanding. For so many years people were mistaken due to the opinion that gravity is slowing down the universe, but such a fact would be true only if gravity were stronger.
Moreover, in 1998 the Hubble Space Telescope studied supernovas and discover that supernovas expanded slower in the past than now, which only strengthens Hubble's theory.
2 The Universe Is Filled With Invisible Stuff
There is a strong belief that we see and know only 4% of the universe, because 96% could be made of dark matter and dark energy we still can’t detect. These unknown substances are thought to push the visible matter apart, which makes the universe bigger and could cause other effects we can’t determine.
Because we can’t detect them, it’s hard to know what it is, so these substances could work according to completely different rules of physics.
1 Our Ancestors Knew More About The Universe Than We Know Today
Our ancestors weren’t as stupid as most believe. While they weren’t building skyscrapers and creating computers, they knew a lot about subjects like herbalism, geography, and astronomy. Keep in mind famous places like Stonehenge, Giza Pyramids, Nazca Lines and hundreds of others that resemble astrological areas ancestors could use to see changes in the sky.
Ancestors believed that changes in the sky played an important role in their lives, so they made it a point to make exact cosmological calculations. Later, they used this information to determine the best time to grow food, travel to dangerous lands, build alliances and make important decisions.
