Scary facts about the Universe
Blackhole
If you fell into a black hole, you would get
stretched out like spaghetti. This is scientifically
known as "spaghettification“ and happens when
"the gravity wants to sort of stretch you in one
direction and squeeze you in another."

The universe is silent
Sound on Earth travels through vibrations in
the air. But in outer space, there is no air for
sound to travel. Hence, the universe is
completely silent.

Fit in the sun
If the sun were like an empty ball, you could
fit 1.3 million Earths inside. The Sun is
enormous and contains 99.86% of all the
mass in the solar system.

Astronaut footprints
Since the moon has no atmosphere, there is
no breeze to slowly erase footprints. They
exist in a vacuum. So, astronaut footprints on
the moon can last for upto a million years.

Between Earth and the Moon
You can fit all the planets between the Earth
and the moon, distance-wise. This is only the
case when the moon is at apogee, also known
as the farthest point from Earth. There would be
still about 5000 miles to spare!

What’s happening?
The reason why we can't see the whole universe
is because some parts are too far away from
Earth. Their light hasn't had enough time since
the Big Bang to reach us. Which makes you
think about what actually is happening in the
whole universe.

Stars
It has been estimated that there could be 1000
billion billion stars in the observable universe,
based on a couple of assumptions about galaxy
size and distribution. There are so many stars in
the known universe, we can't even count them.

Jupiter
Jupiter's Great Red Spot is about twice the size of
Earth. The storm has been raging for over a century.
The planet has been dubbed the "vacuum cleaner of
the solar system", because its gravitational force
eats up asteroids or comets that are nearby,
stopping them from colliding with Earth.

Going outer space
Due to low pressure, the boiling point of your bodily
fluids decreases below your body's normal
temperature, which is about 37 degrees Celsius. This
means your fluids will start to form gas bubbles and
you will swell up, but you won't explode, because
human skin is super stretchy.
