1-5 Interesting Facts and Theories About The Universe

Eridanus supervoid-Interesting Facts and Theories About The Universe

1. There is a large area of space that is devoid of any galaxies called Eridanus Supervoid that is about 1 billion light years across. It has been theorized by cosmologist Laura Mersini-Houghton, to be an imprint of a parallel universe. – Source

2. The average color of the universe is a beige-ish white and therefore the color is named “Cosmic Latte” – Source

3. During one of Stephen Hawking’s lecture in Japan, he was asked not to mention the possible re-collapse of the universe, billions of years into the future, for fears of its effects on the stock exchange – Source

4. Thanks to the experiments conducted in CERN, we now know that every atom in the Universe could be undone in an instant by a simple, unpredictable and an unstoppable event, i.e., a quantum tunnel causing a phase-shift in the Higgs field. – Source

5. A ‘Googolplex’ is such a large number, that if you were to write a ‘1’, followed by a ‘0’ on every single hydrogen particle in the known universe, you would not even get close to writing out the full number. – Source

6-10 Interesting Facts and Theories About The Universe

Mira-Interesting Facts and Theories About The Universe

6. Mira, a dying star zipping through our universe is shedding its matter leaving a tail 13 light-years in length. Each bit of its shed matter may one day grow into a new, individual star and planets of its own. – Source

7. Uranium-238 has a half-life of 4.468 billion years or about 1/3 the estimated age of the universe – Source

8. Pope John Paul II once told Stephen Hawking to not study the beginning of the universe because it was the work of the God. – Source

9. Every time you shuffle a deck of cards, you are almost certainly creating an arrangement, which the universe has never before seen. – Source

10. Approximation of Pi to 39 decimals is accurate enough to calculate the volume of the known universe with a precision of one atom. – Source

11-15 Interesting Facts and Theories About The Universe

Starquakes-Interesting Facts and Theories About The Universe

11. The loudest events in the universe are starquakes. The largest ever recorded was in 2004, the star Magnatar SGR 1806-20 adjusted itself with the force equal to 22.7 on the Richter scale. It happened 50,000 light years away from Earth, but if it would have been 10 light years away, it would have caused mass extinction of all animal and plant species on earth. – Source

12. There are more variations in the game of chess than there are atoms in the known universe. – Source

13. Bismuth has a half-life of more than a billion times the estimated age of the universe. – Source

14. There is a “one-electron universe” hypothesis proposed by theoretical physicist, Richard Feynman in his Nobel lecture, which postulates that there exists only a single electron in the universe, propagating through space and time in such a way as to appear in many places simultaneously. – Source

15. There is a theory proposed by many physicists that our universe may exist inside a black hole and that every black hole in our Universe may contain a totally new Universe. – Source

16-20 Interesting Facts and Theories About The Universe

White hole-Interesting Facts and Theories About The Universe

16. It is theorized that there may hypothetical objects that behave just the opposite of a black hole called a white hole. They cannot be entered from the outside, but matter and light can escape. The Big Bang might have been a white hole itself, and big bangs possibly occur at the center of all black holes. – Source

17. Theoretically, if astronauts traveled in a spaceship at a constant 1 g of acceleration, they could travel the entire universe in their own lifetime, while billions of years would have passed by on earth. – Source

18. There is a theory that our universe has collided with other universes in the past and we can view its scars by studying the night sky – Source

19. Only about 0.0000000000000000000042% of the universe contains any matter. The universe is a pretty empty place. – Source

20. Some scientists theorize that space and time started as one dimension each (basically a straight line). As it cooled, the universe warped into the 2nd-4th dimensions. Some think that the Universe will eventually be promoted again, to a five-dimensional state. – Source

21-25 Interesting Facts and Theories About The Universe

Observable Universe-Interesting Facts and Theories About The Universe

21. Even though the Big Bang happened 13.7 billion years ago, and no object can move faster than the speed of light, the diameter of the known universe is at least 46 billion light years. It is because the expansion of the universe itself can occur faster than the speed of light. Particles cannot travel faster than the speed of light since if a particle has mass then it takes an infinite amount of energy to pass the speed of light. Space time has no such limitation. – Source

22. The coldest temperature ever recorded in the known universe was in Massachusetts, MIT, where scientists attained temperatures 810 trillionths of a degree fahrenheit above the absolute zero (-459.67°F). – Source

23. The universe has existed for just .00000000000000000000000000000000000000000000000000000000000000000000000000000000000000001377% of its expected lifetime – Source

24. Before the Hubble Space Telescope was launched, scientists were convinced that the Universe was no longer expanding. Not only is the Universe still expanding, but it is doing so at the rate of 74 kilometers (48 miles) per second. – Source

25. In approximately 1 Googol (10^100) years, there will be no life, stars, or even black holes left in the universe; only subatomic particles with no way to interact will remain in the ever expanding universe. – Source
