B Term for an end state of expansion?

Click For Summary
The discussion centers on identifying a term for a hypothetical end state of the universe following an expansion similar to the Big Bang. Participants suggest "heat death" as the appropriate term, which refers to a state where all elemental particles are so distant that they no longer interact, resulting in a cold and immobile universe. The concept implies a final, thermodynamic equilibrium where energy is uniformly distributed. A link to a general article on the heat death of the universe is provided for further reading. The term effectively captures the envisioned scenario of ultimate cosmic isolation.

TL;DR
Do physicists have a name for the opposite of a singularity?
Whereas a singularity is everything together, is there a name for a proposed end state after a Big Bang or something similar? Is there a name for that situation (hypothetical or not) where each elemental particle is so far from every other elemental particle that nothing affects anything anymore, and we have a cold, dead, immobile (?) state?

Thanks.

Thank you both. That is exactly what I was looking for.
 
Thread 'Why higher speeds need more power if backward force is the same?'

Thread 'Why higher speeds need more power if backward force is the same?'

Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
