USELESS INFO ABOUT SPACE

Added on: 20th Oct 2016

 

WHAT WOULD HAPPEN IF THE EARTH

STOPPED SPINNING

Earth_precession

Though gravity keeps us with our feet on the planet’s surface,

if standing on the equator, we’re each shooting through

space at 1,040 miles per hour (1,674 kmh). A transoceanic

Boeing 777 can only reach top speeds of 590 miles per hour.

If the Earth magically stopped spinning, we wouldn’t all be

hurtled into space, though, as Earth’s escape velocity is

25,020 miles per hour (40,000 kmh).

 

 

OUR GALAXY IS ABOUT TO CRASH INTO ANOTHER ONE

Andromeda_Collides_Milky_Way

Well, “about to crash” could be relative. The Andromeda Galaxy

is on a collision course for our own at a speed of 68 miles per

second (110 km/s). Despite the speed, this space fact is pretty

irrelevant as it won’t happen for another four billion years.

 

 

THE MOST EXPENSIVE KIMCHI EVER MADE

One of South Korea’s best known culinary exports, kimchi

was brought aboard the International Space Station in 2008

by astronaut Yi So-yeon. Before he blasted off with the pickled

cabbage, the South Korean government spent over a million

dollars to ensure the smell wouldn’t be too acrid for the

other astronauts.

 

 

METAL CAN INSTANTLY FUSE IN SPACE

shielded metal arc welding

A useless space fact for anyone who’s not a space welder,

if two particles or pieces of the same kind of metal (e.g.

aluminium, copper, etc.) come into contact while in space,

they will immediately fuse together. Referred to as cold

welding, the objects will bond because their atoms have

nothing in between (such as air or water) to hold them apart.

 

 

THE LASTING FOOTPRINTS ON THE MOON

Any footprint which astronauts who have landed on the moon

left in the lunar surface will remain there for millions of years.

Since the moon has no atmosphere, neither wind nor

water can wipe the prints off.

 

 

THE SUN ALSO ORBITS ANOTHER BODY

Though we generally only think of the planets orbiting the sun,

our most famous star is also in orbit, around the centre

of the Milky Way Galaxy.

 

 

IT'S IMPOSSIBLE TO KNOW HOW MANY STARS EXIST

Milky way galaxy

Astronomers are able to estimate, with a huge margin of error,

how many stars are in our own galaxy, the Milky Way.

This number stands between 200-400 billion stars. We’re

constantly discovering new galaxies and, with billions of

galaxies expected to exist, it’s impossible to estimate

the number of stars in the universe.

 

 

HUMAN ASHES IN SPACE

Doohan_James_NASA

Over 100 humans have had their ashes launched into space,

including Gene Roddenberry (Star Trek creator) and

Timothy Leary (an American psychologist and advocate for

psychedelic drugs). Clyde Tombaugh was the first person

to discover Pluto and his ashes will have been the first to

leave the solar system after passing by Pluto in 2015.
