Wouldn't things this big be seen easily by many, many earth based observatories? For that matter, wouldn't they show even with high quality amateur telescopes?

If so, how could anyone possibly keep it secret?

[Junior]

It's a conspiracy.

[Gumlegs]

You think they let people see undoctored images through telescopes?

I dated for a few months a woman that worked for NASA as a filing person in the photo analysis department. NASA does have a beyond top secret filing vault; NASA does routinely remove and touch-up photos from this vault for release to the public through selected 'professional' outlets. Amateur astronomers have been finding and cataloging 'anomolies' on the Lunar surface for a coupel of decades now. Do you ever wonder why we no longer go to the Moon, or that no other nation is trying to go there (except China!)?

Do you call it a secret when millions of people consider the evidence and believe and millions of other people refuse to consider the evidence fairly and/or refuse to believe regardless.

It's a secret hidden in plain sight.
