Hint: The earth isn't hollow

And except for small air pockets, a planet couldn't possibly be hollow.

But if it were, I agree with you; there would be a physical explanation.

The Earth is hollow and we're living on the inside of it, despite what the Euclideanists say.

No, but I'm famalir with Cyrus Teed's ideas, which are only of note by the fact that if your willing to be a bit liberal with the geometry, then it's very difficult to disprove.

How much is 'a bit liberal' wrt geometry?

Like being a bit pregnant, my guess.

You can map any point outside of a sphere onto it's interior.

So, in this view, the CMBR would become emission from a sphere interior to the Earth?

What happens when we dig 'down', into the Earth's crust then?

The CMBR stays as the CMBR I suppose, but I doubt antone has looked into the model seriously.

Unfortunately in this model if you dig down deep enoguh you'd find a singular point in your new coordinate system.

Apologies, did anyone ever take the 'holographic universe' seriously? I admit I took a leave of absence from science a couple of years ago. Having come back again, it still looks like the observed universe is still here.

I wonder if this singular point thus corresponds to what in the ordinary world of science we would call the centre of the Earth? Which would be a spherical 'shell', ~3000km 'under' our feet?
