Aye its just coming up in the East now, been waiting for it to come back around. Saturn is in its best spot for years too, just a shame its side on rather than slightly angled to see the Cassini division.

I'm set up for an easterly view so last night the visibles (with eye) were nice, Jupiter looked larger but I missed the scope view. Uranus too.

Satellites have to adjust their clocks, usually twice a day, because they tick faster than on Earth.

Astronauts on the space station age more slowly than us on Earth.

If that broke the 3 Laws Of Logic we would have been told about it. The astronauts are still unique objects and they aren't 2 unique objects existing at the same time.
 
Those are someone's large happy baccy gathering signal. There'll have been a tent, shed or house with psychedelic swirls around it before being picked up by air & breath currents.

you're all talking about swirls near the moon, clearly missing the UFO mid right of shot!

I'm in the pub at the moment but whatever Cox says and however convincingly he says it , Aristotles 3 laws cannot be broken. They transcend physical existence.

"Law of identity: A statement that is true must remain true."

My dinner is hot. If I walk away and come back in an hour, that statement will no longer be true. Suck on that, Aristotle.

P.S. I know, I know, "my dinner" is an object in space AND time, therefore the object that "is hot" only exists at that specific moment in time. When I return to my dinner it is no longer the initial object to which I referred as "my dinner" in my initial statement. ;)

< Einstein’s relativity trumps Aristotle

In the examples they give are there two identical astronauts composed of the same atoms existing at the same point in time ?

They quote the twin study by nasa which suggested that the brother who stayed on the space station more than the other brother aged more slowly while travelling at speed around the Earth.

I’m no scientist so unable to prove if what they claim is true.
