B Term for an end state of expansion?

AI Thread 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 Summary
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 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
