  • It’s utter bullshit from the very start. First, it isn’t true that the Ricci curvature can be written as they do in eqn (1). Second, in eqn (2) the Einstein tensor (middle term) cannot be replaced by the Ricci tensor (right-hand term), unless the Ricci scalar ® is zero, which only happens when there’s no energy. They nonchalantly do that replacement without even a hint of explanation.

    Elsevier and ScienceDirect should feel ashamed. They can go f**k themselves.

    I’ve tried different clients: Element web, desktop, and android, and FluffyChat desktop and android. The problems seems to come, as other have written, when the matrix.org server is involved: it’s people from their handle there which experience glitches joining rooms in other servers. It seems this “part” of the fediverse still needs a lot of development.
