Space has BILLIONS of Stars, Yet it is Cold. Why?

Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning stars in space, why is space so cold?
From a purely technical standpoint, it’s not fair to say that space is cold in itself. Because technically, space is just a vacuum, and vacuum doesn't have a temperature of its own. It’s the objects in space that become cold in due time because they continuously lose heat due to radiation.
In addition to that, it’s not like all these stars are clumped up together. These stars are extremely hot, sure, but they are so far apart and have so much space between them that it’s simply impossible for them to heat up space. It is totally different from what you see when you look up at the night sky. In a nutshell, space is cold, despite having so many stars, because
space contains such an incomprehensibly large amount of
nothingness.

I've never thought about how crazy it is we get to see stars, with how far away they are.

[KayGesus]

Space makes no sense..no matter how many videos I watch, books and articles I read, nothing makes any sense...I love it

[smokeysky]

I recently played Oxygen not included.
And it learned me space is not that cold, it can also be warm. If you have electronics in a vacuum they have nowhere to pas on their energy. So they get really really hot.
And with with the radiation thing, it means that if you are able to see it, it is radiating and loosing energy/temperature

[drvishnu]

Next topic to watch: What is radiation and why do we lose heat through it? Lose it to what?

[quantumxfluxmd]

The closest star being 4.3 light years away would take 48 million years to drive to by car at 60mph.


That's actually a perfect way to depict to someone just how truly incomprehensible and massive space is.

These are good quality animations with good explanation on complicated topics.. I don't understand why this channel has only 139 k subscribers. It should be in millions. I wish u good luck buddy. Keep doing the good work. One suggestion .. you could add some low background music here

[corthew]

I have a better question...How do you lose heat so fast in a virtual vacuum? What exactly is it being absorbed into?

[Mantades]

I want to know if the loss of heat due to radiation (in vacuum) is bigger then production of heat from metabolism inside the body of an average adult human.

[Zenith]

Space is cold

Me: Not exactly. The right thing to say is an object in space is so far from any source of heat or radiation that it ends up losing more heat than it gains, which makes it cold.

[teddywilliam]

please also make it for class 11 and 12 science.
i promise you it is going to be a great hit.and help millions of students
please think about it and make it as soon as possible.

What you mentioned as the Earth’s distance from the Sun is only an approximate, it’s therefore not precise considering that 1 AU= approximately 149, 000, 000 km.

[apogeedata]

What would have been even better for you to explain since hopefully young children are following the James Webb telescope. It would’ve been very nice for you to explain how and why it needs a heat shield because the instrumentation that exposed itself would have been completely burned up by the heat of the sun

[hamzamaqsood]

which software is used to make such videos?

[TheMightyCookieShow]

I could see the massive distances definitely being why space itself is not warm but what I don't understand is why there's no ambient heat in the habitable zone of a of a solar system. Like for example if you were to go to the dark side of mercury they say it would be ice cold there but on the other side everything's on fire I don't understand why there isn't ambient heat that would actually pleasantly warm dark sides of moons and planets that that just makes no sense to me.

48 Million Years Road Trip? Here I come

[Hikingalliance]

Plain and simple, space is composed of 5% material, 25% dark matter and 70% dark energy, so it’s super empty.

[aniketmeshram]

How a deep vacuum can have a gas inside in it 4:16 ????

[ericvulgate]

why is it so difficult to vent heat from the space station?

[TitoTheThird]

3:33 The image is slightly misleading. The diameter of the Earth is about 12, 000 km, while the Karman line is ONLY 100 km above the surface. So the Earth's atmosphere is a VERY THIN blanket in actuality.
