Some astronaut claims to have penetrated the celestial sphere. How would you respond to his claim?

Question

Give reasons for your response.

Answer 1

For navigational purposes a fixed celestial sphere could be penetrated and therefore after penetration be useless as a celestial navigational tool. If an astronaut told me that they had penetrated the celestial sphere I would in return ask at what altitude.

But without a fixed celestial sphere, I would argue that it cannot be penetrated ever because you will always be an observer looking into the celestial sphere. The closest you could ever come to penetrating it would be to run into the end of the Universe. But since the end of the Universe would restrict you from going any farther, you would still have failed to penetrate the celestial sphere.

Answer 2

Are you talking about how the people in Europe during the dark ages percieved the heavens? That the universe is geocentric and there is a shell in which the stars were fixed that surrounded the solar system? If so, that celestial sphere was penetrated long ago.

Answer 3

I would ask him what he was talking about. The "celestial sphere" is not a term with a well-defined meaning.

Answer 4

Oh damn, if he breaks through the firmament, all the water God used to flood the Earth during Noah's time will come down and drown us all.

Answer 5

He needs to show some proof for a start.

What does he want? A medal?

Answer 6

I'd ask the astronaut why they put a hole in their star map...

Answer 7

Answer 9

I'd tell him, "Get over yourself and just say you've been to space."

There's no need for that kind of language.

Answer 10
