What is the source of cold in the universe?

It seems the default reality in the universe is COLD! But where is the source of this cold.

"The astronomers claim it’s the original background radiation This is the temperature of the cosmic microwave background radiation, which permeates the entire Universe. In space? It’s as cold as it can get."

That doesn’t answer my question at all

We all know the ultimate source of heat and that is the stars or suns in the universe.

However, what is the ultimate source of cold?

Because it turns out that the universe is mostly terribly cold. Without any suns around nearby the temperature, that call absolute zero is -270 degrees Celsius.

Let’s talk a little further out. As you travel away from the Sun, the temperature of an object in space plummets.
The surface temperature of Pluto can get as low as -240 Celsius, just 33 degrees above absolute zero.
Clouds of gas and dust between the stars within our galaxy are only 10 to 20 degrees above absolute zero.
And if you travel out far away from everything in the Universe, you can never get lower than a minimum of just 2.7 Kelvin or -270.45 Celsius.
This is the temperature of the cosmic microwave background radiation, which permeates the entire Universe.
In space? It’s as cold as it can get.

So the question remains, as we know the source in the universe of heat we don’t know where the default reality of the universe, which is cold, comes from.


Is it some kind of massive body of ice hidden somewhere we cant detect?


What is the opinion of the many fine ATS thinkers

It's generated in the void where my soul should be.




The cold is the lack of heat. It's only cold in contrast with the heat generated by the stars. Without the stars and their heat it wouldn't be cold, it would be nothing.

Like asking what the source of darkness is perhaps. Darkness doesn't need a source, light does. Cold is the absence of heat, so you don't need a source.

Only heat source is the sun ? It makes atoms go faster?

a reply to: Willtell

I always thought maybe black holes emit the cold or suck up any heat. Black holes suck up heat while suns emit it.

Maybe solar wind has its effect?

No humidity could lead to some clues?

This is a great question that I have randomly thought about.

Kind of like the speed of dark kind of thing it seems.

When you spin something it seems to cool I think as well might be another lead?

However, what is the ultimate source of cold?

Blackholes ?

Like leaving a door open in the middle of winter sucking all the heat out of the room.

Space is just a very big room, and there are millions of doors.

Just a thought

Cold doesn't need a "source."

Cold is lack of heat.

There is no such thing as cold . There is only varying degrees of heat . If you remove all the heat , that is as cold as you can get . Absolute zero .

Beat me to it. Cold is the absence of heat and energy. If you believe in the paranormal, it is why things suddenly get super cold right before an entity manifests in this dimension, it has to draw the energy to do so.

Thanks for some Great answers.


This is a deep question that is a mystery.

We don’t know really what cold is. Is it just an illusion?

Just relative to physical reality?

We know where heat comes from but we don’t know anything about the source of cold in the universe at all. It is apparently the default state of the universe.

Why is it cold? What is cold?

I like some of the answers that speculate that black holes may be emitting the cold. But wouldn't we see that in some form.

a reply to: SirHardHarry

Then heat is a lack of cold

Fine

The mystery though is we know the source of one side of the equation, that is the source of heat

But we know not the physical source of cold...
Just saying its a lack of heat doesn't answer the question, I'm afraid

a reply to: Willtell

Why is it cold? What is cold?

The state of being without heat.

that speculate that black holes may be emitting the cold.

Um, no.

There is no physical "source." It's the absence of.

a reply to: Willtell

uhhh...

there is no source of cold.

everything is cold unless there's some energy to make it warm.

Agreed, if zero heat is around then cold must be and visa versa.

The question makes no sense. The idea of something being deemed "cold" requires something to sense it. Without something to sense it, being "cold" has no meaning. It's just a state of the Universe. Technically, I suppose, it's the absence of movement in molecules. Why does that requires a source? Now if those molecules start to move (meaning they are above absolute zero), then maybe we're on to something because we can investigate what is the source of that movement.

Um, no.

However, cold is a phenomenon. What is the source of the phenomenon?



Let me refute your answer with an analogy

That’s like saying hate is a lack of love.

However, we can see a source for hate. When can a source for anything be an incomplete equation?

We cannot see a source for cold!

Therefore, your answer (A lack of heat)
Is not sufficient in answering the question


why is it so cold? Enough where even atoms don’t work!

Why is it a default of -273 Celsius…? so cold even atoms stop working

Why not -290 degrees


Or -150 degree Celsius

Absolute zero is the absence of all motion.

Love and hate are emotions. Heat and cold aren't, they're attributes to physical properties.

There is no source there is only absence/lack of heat.

why is it so cold? Enough where even atoms don’t work!

Because there is no heat; and energy is absolutely minimal.
