In the EFE, if we move the cosmological constant factor to the right handside, where the stress–energy tensor is, then stress–energy tensor and the cosmological constant factor have opposite signs and stress–energy tensor can overcome the cosmological constant factor.
When we say EM-forces/Strong/Weak forces "cancel out" the expansion of the universe, it isn't because of those forces are holding matters together. But they contribute to the stress–energy tensor and "offset-ed" the effect of the cosmological constant factor.
Even without those forces, as long as the stress–energy tensor is greater than the cosmological constant factor, the solution of EFE will be non expanding.
Does this sound right to you? Thanks.
The example you given is actually irrelevant for consumer use cases. For consumers, loading speed matters. They are interactive apps. They can't spend too much time loading. While for film studio, they are batch rendering scenes. Loading speed is a lot less important.
Aurora is a log structured db, they can just reset their DB to a particular LSN. i.e. doing "git reset --hard", which's O(1).
We should work together on getting rid of the ancient and manipulated election system and revamp it with a modern proportional representative system.
