Relativity only applies to local reference frames and not to the recession rates of cosmologically distant objects.

I can't find any reference that says it's moving away from us at twice the speed of light, which would violate Relativity. The fact that it is further away from us in light years than the age of the universe in years, is due to the fact that the space itself is expanding.
It doesn't. Gravity is caused by mass not spin. The planet's rotation about it's own axis will create a centrifugal effect that offsets gravity, but the effect is negligible for anything rotating as slow as planets.
It doesn't take much research to find out she was against wearing masks during COVID, she's pro-Brexit, and she's a climate change denialist.
In short she's a reactionary fuckwit, who should be ignored.
You will know us by the trail of our rubbish.
I played the original Elite on the BBC, and then Elite 2 & 3 on the Amiga. Elite Dangerous on the PC was just plain dull by comparison.
Not sure those categories are mutually exclusive, in which case a pie chart is illogical, captain
Does the world have a government or did the headline perhaps forget to mention that it's referring to one particular country...?
I studied Relativity at university as part of combined Physics/Maths degree, but please feel free to continue entertaining us with your popular magazine-based learnings.
If the gravity were strong enough and the source close enough then the tidal force would absolutely be strong enough to simultaneously crush you and rip you apart. The same effect gives rise to tides on this planet, hence the name.
I was thinking of the Equivalence Principle:
the equivalence of gravitational and inertial mass, and Albert Einstein's observation that the gravitational "force" as experienced locally while standing on a massive body (such as the Earth) is the same as the pseudo-force experienced by an observer in a non-inertial (accelerated) frame of reference.
