All matter being liquid in 10^65 years if proton decay doesn't occur.

Click For Summary

Discussion Overview

The discussion revolves around the concept of matter transitioning to a liquid-like state over an extremely long timescale of 10^65 years, assuming protons do not decay. Participants explore the implications of quantum tunneling on the arrangement of atoms and molecules, questioning the nature of matter in this distant future.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that over 10^65 years, all matter will behave like a liquid due to quantum tunneling, implying a rearrangement of atoms and molecules.
  • Others clarify that this does not mean matter will literally turn into a liquid phase, but rather that it will exhibit liquid-like properties over such a long timescale.
  • A participant questions the concept of gas "melting," pointing out that at such extreme future timescales, the universe would likely lack gas due to low temperatures and the absence of stars.
  • Some argue that solids will retain their solid phase but will appear liquid-like due to atomic rearrangement, raising questions about the survival of intelligent life in this future scenario.
  • A metaphor is provided comparing the behavior of atoms in solids over time to people in a confined space, illustrating how changes are only perceptible over vast timescales.

Areas of Agreement / Disagreement

Participants express differing interpretations of the implications of matter behaving like a liquid. While some agree on the liquid-like behavior of matter, there is no consensus on the specifics of what this means for the phases of matter or the existence of gas.

Contextual Notes

The discussion highlights assumptions about the nature of matter and the effects of quantum tunneling over extreme timescales, but does not resolve the complexities involved in these concepts.

10^65 years in the future.

Assuming that protons do not decay, estimated time for rigid objects like rocks to rearrange their atoms and molecules via quantum tunnelling. On this timescale all matter is liquid.[49]€
Does that mean in 10^65 years in the future, if proton decay doesn't occur, only liquid will exist. Solid, gas and plasma matter will no longer exist?
 
Space news on Phys.org
Just judging from what you said in your post, they are saying that all objects will tend to 'melt' over extremely long periods of time because of quantum tunneling.

Just like some (all?) glass will seem to melt over hundreds of years if you watched a rock for a bajillion years it would also seem to melt (but for surely different reasons).

An interesting idea.
 
No. That's not what it means. It means that over a time period of 10^65 years, due to quantum tunneling, atoms will rearrange themselves, the same way liquids do but much much slower, making it seem as if matter is a liquid. It doesn't mean that all matter will suddenly turn to liquid. Read it carefully.
 
it's saying that on this timescale, all matter is *like* liquid. When they say it is liquid, they don't mean the phase, they mean the adjective "liquid"
 
How can a gas melt?!
 
Oh, so that matter will still be in the solid phase but it will seem like liquid.
 
Correct, the atoms will slowly rearrange in the solid making it look like it's kinda liquid like.

But remember that the timescale is incredibly long too.

Over this time scale I doubt there is any gas. There would be no stars and the average temperature of the universe would be incredibly low.

Oh, so it would still have properties of solid like definite shape, but it will look like liquid. I wonder if (intelligent) life would be able to survive this change if it still exists in this incredibly long period of time.

heh, well, imagine telling about a thousand people to stand in a room where there's a bout a square meter for each person, and then just leave them in there for a while without telling them to do anything. I imagine they'd act a bit liquid.

I think the point is really that this is a change that is only noticeable over these ridiculously long time frames. People don't live long enough to notice it because a person doesn't even live for 10^2 years.

It's not that the stuff changes into some liquid stuff, it's that if you watched all the atoms in some solid for 10^65 years, and then sped it up really fast, it would look like a liquid because the atoms would be moving around like a liquid.

Solids will still be solids if you just took a short glance at them, but over these enormous lengths of time, they'd act like liquids.

For example imagine some water. But only imagine the water for an instant, like a picture of water. The water looks solid, doesn't it? It's the same idea.
