Stargazing in a mineshaft?

A friend told me this and asked me to find out if it’s true or not. Like I have all the answers!

If you stood at the bottom of a deep mine shaft during the daytime, could you see the stars?

P.S. I promise you’ll get credit for the answer, not me

Nope. Try this: cover one eye, look at the sky through a length of pipe with the other. This should approximate your view from the bottom of a shaft. What do you see?

No. Someone will provide a cite, but essentially, the sun illuminates the atmosphere, not just the solid mass that is the Earth. Thus, no matter what you do, unless the Sun is removed (e.g. at night) you will not see the stars. J String’s point is a valid one.

This is one of those myths that persists because it’s too much hassle for anybody to actually try it and find out that it’s complete bullshit.

Not too many people have access to ducks and good echo sites, either.

However, if you want to collect neutrinos, the bottom of a very deep mine is a good place.

Right you are Muffin! I thought that was what this thread was going to be about.
