[BLOO JAM] 10 Space Facts That Will Keep You Up At Night
With space being so massive and limitless,
there are a bunch of weird quirks about space that scare even astronauts and scientists!
10. There are galaxies eating each other up
Cannibals are just about the freakiest thing we have here on Earth, but what if we told you there
are actually cannibals in outer space. While the concept may sound ridiculous, it’s actually true,
but it’s not humans eating other humans, but galaxies eating up other galaxies. The phenomenon
is known as Galactic Cannibalism, and it stems from a phenomenon when two similarly-sized
galaxies start to merge with each other to form a larger galaxy. But that’s more of a mutual merger,
with galactic cannibalism, it’s when a larger galaxy starts to merge with a much smaller galaxy,
and over time, the smaller galaxy gets completely absorbed into the larger one, to the point where
the features and characteristics of the smaller galaxy are almost absent from where it once stood.
9. One day, the night sky may be entirely black
Speaking of galactic cannibalism, there may also be some serious consequences of such
events happening. While there are still hundreds of thousands of years before something like this
happens, but many scientists believe that due to the merger and cannibalism of many galaxies,
including the milky way, the night sky may, one day, become pitch black. There
would be no moonlight, no stars, nothing. If the human race even survives that long,
it may have serious consequences to not just the Earth’s geography, but also human biology.
We’ll all be long gone before that day ever comes, though.
8. There are dead bodies in space
Throughout the course of history, hundreds of people have made the journey to space after years
of training and studying. Most of the missions to space have been highly successful and almost
all of them made their way back to the earth safely. Almost is the keyword here, unfortunately.
There have been plenty of accidents where spacecraft have had a malfunction
and exploded or crashed within space, and multiple astronauts and cosmonauts have lost their lives,
many of them remain effectively buried in space. In 1971, a Soviet spacecraft carrying 3 cosmonauts
became decompressed in space due to an engineering fault, the spacecraft was well above the Karman
line, making this accident the farthest anyone has ever died from the earth. Other major accidents
have also happened, such as the Space Shuttle Columbia disaster where a team of 7 American
and Israeli astronauts lost their lives after the space shuttle disintegrated within space.
7. The world could end in the blink of an eye
Truly one of the scariest facts about space is how deadly it is. There are objects in
space that can hit the earth at any time, without warning, and one of these objects
may just wipe all the life off of our planet, if not destroy the planet entirely. Something
like this happening is not entirely unheard of, as mass extinctions have happened in the past.
Such as the Cretaceous–Paleogene extinction event which happened over 66 million years ago.
The Cretaceous–Paleogene extinction event saw nearly two thirds of the entire planet’s
life be wipes out, including all the dinosaur species on earth, it’s believed that the event
happened due to an asteroid colliding straight into the earth. It’s been millions of years since
that happened, but the chances of something like this happening again are very high.
6. The universe is completely silent
The universe is extremely mysterious, and we don’t really know much about the function of the
universe, but what we do know is that, unlike in the movies where you can see astronauts or aliens
actually talk to each other in space, as they do on earth, in reality, space is dead silent.
Such silence is almost eerie, but there is no sound whatsoever in space.
This is because space is entirely a vacuum, and no sound waves can travel through this vacuum.
5. The size of the Sun
We see the sun every day, and at this point, we all know that the sun is big, but how big
is it? The radius of the sun is around 696,340 km, in comparison, the earth’s is only around
6,300 km. The sheer difference would be almost incomprehensible to most people, but to add
another layer to this, if the sun was a hollow ball, you would be able to fit 1.3 million earths
inside of it. Next to the sun, the earth may look like a tiny dot, but it gets even crazier when
you consider the fact that, when compared to many other objects in the universe, the sun might not
even be that big. The largest star in the universe that we know of has around 2,150 times the radius
of the sun, which is about 1.3 billion km! Much like the earth looks like a tiny dot next to the
sun, the sun looks like a tiny dot when put next to this star, which is called Stephenson 2-18.
4. Venus is the most dangerous planet in our solar system
There was a time before the Mars craze when most scientists thought that Venus might be the first
planet that humans will explore themselves. All these plans were put to a stop, though,
when they realized simply how crazy Venus was as a planet. It’s, by far,
the hottest planet in the solar system, despite that title often being misattributed to Mercury.
The average temperature in Venus is around 850 degrees Fahrenheit,
compared to Mercury’s maximum of 800 degrees on its sunny side. Venus, unlike Mercury, is
entirely hot, while Mercury still has a freezing cold side to it. Venus is hot enough to melt lead,
making it almost impossible to send any spaceship on the surface of this planet.
3. Astronauts have to drink their own recycled urine
The life of an astronaut is tougher than you think. Despite the glamorization of
astronauts in the media may make us think of astronauts as living these crazy exciting lives,
and while that’s true for a few moments, the majority of it is quite boring and difficult.
Having to adjust to zero gravity is extremely challenging on the body, and simple day to
day tasks can be a huge task if you’re an astronaut in space. Even to sleep, they have
to wear multiple belts in order to prevent their limbs from just floating around while they sleep.
And since there’s literally no water in space, they actually have to recycle their own urine and
convert it into water in order to meet their daily water needs. Living in space isn’t for everyone.
2. There is a very large chance there may be life beyond the Earth
The earth is the only planet, the only object in the universe, that we know has life on it.
Over the past few hundred years, billions if not trillions of dollars have collectively been spent
in order to not just explore our solar system, but to find life beyond our planet. So far,
we haven’t found any life, but we’ve also only explored a very tiny part of our universe overall.
Even the planets we have flown by, we didn’t exactly get details of each planet’s surface,
and we have very few samples of these planets that may contain microorganisms that we can’t
see with the naked eye. The possibility for life beyond our planet is endless,
but the problem is that the universe is too big, and our resources are too little.
Who knows, maybe somewhere out there, there’s a planet just as thriving with life as our own.
1. We only know about 4% of our universe
And that brings us to our top pick for this video, and that’s simply the vastness of the universe.
We only know about 4% of our universe, the rest is still yet to be “found” by humans?
When it comes to how much of the universe we’ve actually explored, it’s probably not even 0.1% of
the 4% we only know about. This raises the question, what really could be out there?
Some new kind of black hole? Advanced alien species? Planets even larger than the Sun? Or
just a whole bunch of nothingness? We might never really know in our lifetime, and there’s also a
possibility that the universe is endless. There was a time when we didn’t even know there was a
universe beyond the Milky Way, and while exploring that much of the universe may seem like an
impossible task right now, think of the progress we’ve made in space exploration since the 50s,
at the rate technology is progressing, we might just know the secrets behind the universe.
