Title: Photos taken this morning of the horn antenna that discovered the CMB in 1964

As said earlier these photos were taken on the former Bell Labs grounds on Holmdel road in Holmdel NJ, USA.

You are arguing how great America is and I am saying that it's BS

They must have cleaned out the antenna - originally, they attributed the CMBR to pigeon poop that had accumulated inside the antenna while it was sitting unused.

I must have missed this argument.

It's pigeon poop, not BS.

And cows can't jump over the moon (without considerable assistance).

I wasn't.
How did you come to that conclusion?
Is this your reading comprehension problem again?

They cleaned it at the time.
My recollection is that they removed what they referred to as "a white dielectric substance" in the published paper.

Hi all,
I don’t know how true it is but I was once told the pigeons were re- homed and they did what pigeons do and promptly returned, so they were dispatched to a more permanent retirement.
😔

Went there again today with my wife, she was flabbergasted that such a piece of history would be sitting rotting in a back lot, the Smithsonian wants the ear but Bell refuses to sell.  I am going to go back with my Nikon and various lenses to take better photos.  As for the poop, there is still plenty of it and a herd of whitetail running around as well.

sitting rotting in a back lot,
Either they used really good paint back in the day, or someone has been painting it regularly which is all the maintenance it needs.

It was not built to be kept indoors..

The paint is peeling and they have turned it down so no rain collects in the dish.  The device actually needs to be cleaned, refinished, lubed and rotated to keep the parts from rusting together.  The space shuttles were not built to be indoors either but that is where they are, along with the Messerschmitt 262 and Horton flying wing remnants
