30 Amazing Facts About Universe | Amazing Facts 4U
- The amazing fact is there Are at Least 10 Billion Trillion Stars in the Universe.
- 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 about 150 billion light-years. It is because the expansion of the universe itself can occur faster than the speed of light.
- Every hour the Universe amazingly expands by a billion miles in all directions.
- The universe is so amazingly empty that it is like a building 20 miles long, 20 miles wide, and 20 miles high that contains 1 grain of matter.
- The amazing fact is only about 0.0000000000000000000042% of the universe contains any matter. The universe is a pretty empty place.
- All the stars, galaxies, and black holes in the universe only compose about 5% of its mass.
- What is amazing is that the other 95% is unaccounted for. Scientists decided to label this mystery material “dark matter” and to this day they are still not sure where or what it is.
- While neutron stars are only about 10-13 miles in diameter, they are heavier than many stars.
- The amazing fact is that a thimbleful, or sugar cube, amount of a neutron star weighs around 100 million tons. That’s more than a large mountain.
- Hydrogen is in fact the most common atom in the universe.
- A single quasar produces the same amount of energy as 1 trillion suns. The brightest quasar is 2 billion light-years away.
- Quasars are the most distant known objects in the Universe. Even the nearest is billions of light-years away.
- The biggest thing in the observable universe, which is a so-called “large quasar group,” or LQG was discovered recently. It spans an amazing distance of four billion light-years or 24 sextillion miles.
- Time slows down near a black hole; inside it stops completely.
- Amazingly the sky looks blue because when sunlight enters the atmosphere colors of the shortest wavelengths are scattered (Violet & Blue)
- A dog was killed by a meteor in 1911 in Nakhala, Egypt. It is the only creature to be killed by a meteor.
- At only 1 Degree above absolute zero, the Boomerang Nebula is the coldest place in the known universe.
- The deepest picture of the universe ever achieved by mankind was taken over almost 4 months and was taken amazingly over the course of 400 Hubble orbits around Earth during 2003-2004.
- 6 to 10 billion light-years away, there is a void in space amazing one billion light-years across called Eridanus Supervoid. It is completely empty of both normal and dark matter and is a big mystery. It emits no detectable light or radiation of any kind.
- Amazingly Sagittarius B., an interstellar cloud of gas and dust 26,000 light-years away contain over a billion billion billion liters of vinyl alcohol.
- In 2004 scientists discovered the largest diamond ever. In fact, it’s a collapsed star. Measuring 4000 km across and having a core composed of 10 billion trillion trillion carats it’s roughly 50 light-years from the Earth.
- Amazingly in 1977, we received a signal from deep space that lasted 72 seconds. We still don’t know how or where it came from.
- The amazing fact is there is a mass reservoir of water floating in space that is 100000 times larger than the Sun holding 100 trillion times more water than all our oceans combined.
- The approximation of Pi to 39 decimals is accurate enough to calculate the volume of the known universe with a precision of one atom.
- 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.
- Bismuth has an amazing half-life of more than a billion times the estimated age of the universe.
- Uranium-238 has a half-life of 4.468 billion years or about 1/3 the estimated age of the universe
- The loudest events in the universe are starquakes. The largest ever recorded was in 2004, the star Magnetar SGR 1806-20 adjusted itself with a 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 the mass extinction of all animal and plant species on earth.
- 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).
- Our universe will not last forever. 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.
