Then evaluate surface area of a sphere in both coordinate systems.
You'll see something interesting if you actually do the computation.

The multi-year super-senior has nothing to say besides the stupid
question in which I have given the answers already more than once.

There is no short cut in such type of mathematics. shrug

Based on your years of not studying the subject?

Equivalent years, yes. shrug

But mathematically, its Ricci and Einstein tensors also vanish.

Not if they use the Schwarzschild coordinate system.

Since both metrics use the same coordinate system, you are just
whining about something you do not understand. shrug

Perhaps, there is a flaw in your Cartan whatever. As I said, anyone
who possesses mathematical software like Eric Gisse can easily verify
it, and I do not see any complaint from that multi-year super-senior.

That's because we [JanPB, me] understand that the r you use is
different from the r in Schwarzschild even if you don't.

Hahaha, is this the best I can do with an amateur tag-team of JanPB
the queer of England also a part-time film critics of second rated
movies and Gisse the multi-year super-senior who sits on his piles of
books for fun?

You appear to think that the coordinates determine the physics.

On the contrary, I have been telling you the exact opposite. shrug
There is no need to continue.
