CRAZY MYSTERY OF UNIVERSE!!

Spending time in space is ultimate fiction dream for many of us. But do you know our space is full of crazy mysteries and life seems very strange there. Since the dawn of time to this day, astronauts keep revealing the more interesting facts about universe... Yet some of them are very funny..

       Our universe is so vast that it's difficult to know the full extent of it's complexities. Here we've very few of them. So let’s discuss what they say about universe..!!   ➽➽

Now the time to explore.. lets go..

Early universe was made up of Hydrogen & Helium. following the fusions, other elements were also formed in the core of stars as well. As we are also made up of organic matters, surely we're also forged in the center of stars!!

Every object radiates or reflects light to get marked in our eyes and it takes around 80 milliseconds to relay & translate the information to us. Even the time is less than a second, that's also not a fresh moment. So we actually live in past!!

American Astronaut Don Pettit

      

Actually in zero gravity in space, tears form a ball around the eyes. The more you cry, the ball of tears would continue growing bigger and bigger..!!

As our MILKY WAY is rotating at a speed of 225 kms/sec and with it we too are racing at a speed of 530 kms/sec. So in future if you ever think that you've accomplished nothing today! Remember that by the time you blink your eyes, you've traveled a lot..!

When you're actually in orbit, without gravity body fluids move towards your head. Your stomach gets flat and you feel taller as you grow an inch or two!!

As there is no soil & no dirt on space station, they need a substitute which can hold water and seed both. The dirty underpants if folded in spherical shape & stitched with wool like toilet paper gives a warmer environment for seed to sprout..!!

Venus spins to the opposite direction of earth but it's rotation is too slow that it takes about 243 Earth days to complete 1 spin and bcoz it's so close to the sun, a year goes by fast and it takes about 225 Earth days for Venus to revolve around the sun..So a year is shorter than a day on Venus..

Also Venus spins backwards so Sun rises in west and sets in east..

Our universe is not made up of just atoms, it's made up of innumerable TINY STORIES. We may never understand the entire universe but we can surely appreciate such crazy yet much interesting facts..#
