From some of the coldest places in the universe, to some of the hottest places in universe,
to those that even balance hot and cold at the same time! Join us as we show you some
of the most extreme temperatures in the universe! 10. Antarctica
Let's start with a place close to home, shall we? On Earth, the absolute coldest and most
extreme place temperature-wise in regards to the cold is easily Antarctica. Now, usually
we'd note that this was only because of a certain season, or a special place in Antarctica
that has such a "cold spot", but that's not the case. Rather, Antarctica is the coldest
place on Earth year-round very consistently because the temperatures on the massive continent
are frequently in the below zero range by a wide margin.
One time, some people in space took a measurement of Antarctica (which is a fairly more accurate
way to do it) and found that it was at a blistering -93 ºC ( -135.8 º F ) Which is freaking
cold. And even the average temperature is only slightly better at -81 degrees Fahrenheit.
Because of this extreme cold, there is a lot of extreme weather on the continent as well.
The winds can make the already cold weather feel much worse. And the storms are known
to be so bad that they can cause serious whiteout conditions, or even hurt people who are inside
houses. Due to this, there aren't many people who
"live" on Antarctica. In fact, there are only a few THOUSAND people who dare trek to the
continent every year, and that's only because they're scientists. Ones who study Antarctica
and how the animal species that live there survive. But in regards to those who seek
this place as a home humanity wise? No, it's not happening, because this is too extreme
a place to live, survive, and be happy in. 9. The Hadron Collider
Think we're heading into space now? Not so fast, there are still some extreme temperatures
on Earth that need to be recorded. So, we've seen the most extreme cold temperature on
the planet, but what about the most extreme in terms of heat? You'd likely think of a
volcano, or a thermal vent on the ocean that is connected to the Earth's core and thus
has millions of degrees to burn you with (and yeah, it does). But actually, you need to
not look at nature, but man, specifically the CERN Hadron Collider. No, the collider
itself isn't that hot. But what it did once was definitely hot in the literal sense.
During one experiment, they went collided two led ions together at incredible fast speeds
(which is what the Collider is supposed to do for the record). The result of this collision
was the hottest man-made temperature ever created via a 5.5 trillion Kelvin temperature
reading. That's pretty impressive, especially for humanity.
Granted, we can't sustain such a temperature long-term just yet, but we know it's possible.
And that knowledge can lead to certain things in the future. And because of that, theoretically,
we could even create even hotter temperatures. 8. The Emptiness of Space
If you wanted to go out into space, you'd need a lot of protection. But not just from
radiation, the lack of oxygen, but just as important, from the temperature. Which honestly
isn't something you think about a lot when you talk about space as a whole. So that begs
the question, what is the temperature of space? It's not something that's often taught because
it doesn't affect us unless we're out in it via being an astronaut. In truth though, it's
very important, but what the universe does is something humans cannot without great effect,
stay at –273.15 º C (-459,67 º F)
Or as we call it, Absolute Zero. Now, to be clear, the entire universe is not
Absolute Zero, however, the average is about that, maybe a few degrees warmer, but still.
The universe is really cold, and humanity views Absolute Zero as the coldest temperature
you can achieve (though research states you could go beyond that technically). So if we
have a hard time doing it, how can the universe? The answer is expansion of gas.
Heat is always in motion, and so the universe uses the expansion of gas to push the heat
away and thus make the universe really cold. It's a similar principle to what the refrigerator
in your house does. And if you're curious how the Earth isn't
affected by this cold, that's because our atmosphere keeps the heat in. If you want
to see what it's like without it, look at Mars or Pluto.
The point is, if you want to see one of the most extreme places in the universe in terms
of temperature, you need not look far. You just have to look up at space itself.

7. Boomerang Nebula Now, as I just noted, the average temperature
of the universe at large is about absolute zero. It varies from place to place where
you go and what's there (meaning that a literal empty space area will be different from a
place with a few suns). But, in the case of the Boomerang Nebula, people state that it's
the coolest natural place in the universe. What does that mean? It means that unlike
space itself (which is cooled via the movement of gasses across the entire universe), the
Boomerang Nebula keeps itself cool in a natural way. By its own function and not anything
else. With its temperature being just shy of Absolute Zero at −272.15º C ( -457.87
ºF ) . That's right, this place is one degree away from Absolute Zero, that's really cold.
In case you're curious, the Boomerang Nebula is actually 5000 light years away from Earth
in the Centaurus Constellation. And it's a big focus of scientists because of its extreme
temperature. They believe that the place itself was a former star that is moving into the
Nebula Phase of its life, which would explain its cold temperatures and the shape it has.
This transitional phase is (just like the universe at large) producing large amounts
of gas that is expanding in the area, thus causing the cold temperatures.
6. Tidally Locked Planets I want you to think about how the Earth works
as a planet. No, not in terms of its people and governments, but rather, how it moves
around the sun itself. It has an orbit around the sun that dictates our year, but it also
rotates itself around an axis every 24 hours. Meaning that all sides of the planet are exposed
to the sun. However, there are planets out there that are known as "tidally locked" planets.
These planets don't rotate on an axis every day. Instead, they have one side facing the
sun, and the other side receives no sunlight at all. These planets are known for being
planets of "extremes" because the temperatures on the two 'sides' of the planet are vastly
different. One such planet for example is CoRoT-7b, which
is a planet that rains rocks because of its extreme temperatures. The side facing the
sun has large pools of lava, but because it's so hot (reaching 2600 º C (4712º F) (at
times), the lava actually evaporates and goes into the atmosphere, and then it'll either
stay on the hotter side of the planet, or, go to the other side, which is much cooler
than the regular side. When it "rains" on the hot side, it becomes magma. Yet, when
it goes to the cooler, it hardens into rocks, and can become so big that they damage the
surface on the ground.
There are many planets out there that have this kind of extreme temperature difference.
Often times being THOUSANDS of degrees apart from one another and causing all sorts of
weird weather effects as a result.
5. The MIT Billionth And...back to Earth we go! Because as we look
back at how hot and cold the universe can be, we must once again talk about how humanity
is trying to replicate the events that happen naturally in the universe with their own technology.
As noted, Absolute Zero is the coldest temperature possible, but at present, humanity has never
been able to naturally replicate that temperature. However, in 2003, a group of scientists at
MIT can devilishly close to doing that. How close were they? Well, they got within a Billionth
of a degree of the number. They were JUST above it.
This was quite an achievement no matter what way you look at it. And even though humanity
didn't get to absolute zero, they did get close, and that means they could theoretically
get there at a later time. And in case you were wondering, yes, this is the lowest man-made
temperature ever recorded. 4. Nuclear Bomb
Oh yeah, it's time to drop the bombshell! There's a reason why the nuclear bomb threat
is one of the biggest threats in our world today. Because the destruction that it can
cause is unlike just about anything else mankind has created (and trust me, mankind has made
a lot of destructive stuff). Yet what might be the most dangerous thing about the nuclear
bomb is something that isn't widely known, the initial heat burst that is emitted.
There are actually many layers to a nuclear bomb, and one of them is that upon detonation,
there is an X-Ray wave that bursts out in all directions. That wave is 10 billionº
C( 18 billionº F) in heat. This is but the first step in the destruction that the bomb
causes. Now, if you're wondering why we don't know about that wave, it's because after it
is released, it's quickly absorbed into the atmosphere. Thus why the area around the bomb
isn't melted away over the course of a few seconds. It's burned, and destroyed, but not
to the level of 10 billion degree heat. Which goes to show you that sometimes the
most dangerous things are the things you can't see.
3. Dark Side Of The Moon Pink Floyd song going through your head? I
don't mind. It's a good track. But there's a reason why the phrase "Dark Side of the
Moon" is so relevant in the world, and universe, today. Because not unlike the tidally locked
planets I mentioned earlier, the moon is also one that has one hemisphere always facing
the sun, and then have the other side not facing the sun. It's eternally dark on the
back side of the moon, and that means that the temperatures there are freezing.
How freezing? About -184 º C (-299,2 º F ). And that temperature and darkness is multi-layered.
Because the moons' surface is reflective, which is why you can see it in the sky when
it's dark. But it also helps ensure that various signals reach the Earth. That's why in the
many moon missions, there was always a point where the astronauts couldn't talk to NASA
because they had to go to the Dark Side of the Moon. No signals could bounce back from
there. And that's why if we were ever to colonize
the moon, it'd be on the side facing the sun, because we wouldn't dare try and live on the
other side. 2. The Big Bang
While not something that is constant in our universe at the moment, scientists believe
that when the universe was born via the Big Bang, the energy and temperature were so incredible
that they almost broke all the scales we have. In regards to heat, the people who document
the "timeline" of the Big Bang state that within the first few fractions of a second
when the event itself happened that there was a temperature of 1 Octillionº C ( 1,8
Octillionº F ) in the universe. While this may be an astonishing thing to
ponder, it's actually not without merit. After all, the Big Bang is said to have created
our universe with a massive explosion of energy. To that end, the literal "explosion" aspect
of the event must have caused a massive surge of heat unlike anything the Earth has ever
seen before. Or since in many regards. Granted, all of this is rough speculation
based on what scientists think happened at the beginning of creation, but, if it did
happen, that also means it could happen again. And should it happen, even if only man-made
as part of an experiment, it would be the hottest recorded temperature in the history
of the universe. 1. Planck Temperature
We started off this list with references to some of the coldest temperatures in the universe,
and showed you some hot things along the way, but have you ever wondered what the hottest
theorized temperature in the universe is? That would be the Planck Temperature, also
known as "Absolute Hot". In numbers, that'd be 142 nonillionº C (255 nonillionº F) which
is a LOT of zeros for the record. Scientifically speaking, Absolute Hot is by
and large the hottest an object can get under the current forces of physics, mainly via
gravity. It's stated that should anything SOMEHOW get hotter than that point, it would
break the laws of physics. Which would be very impressive if we're being honest with
you. That being said, while there is certain basis
for the belief of Absolute Hot, not everyone believes the "scale" that it is on. And thus
speculate (not unlike Absolute Zero) that there are temperatures that are hotter than
142 Nonillion degrees. It's just a case of us not having found it yet. Whether this is
true or not is solely dependent on finding proof of the theory either way.
Still, if you wanted to note the hottest temperature in the universe, the Planck Temperature or
"Absolute Hot" would be the correct answer more or less.
Thanks for watching everyone! What did you think of these hot and cold places in the
universe? Can you believe the extreme amounts of temperature that is produced both on Earth
and in space? Do you think there are even more extreme temperatures out there waiting
