My personal experience with ULP; Experience happened on December 31st, 2021 at approximately 1400 hours or 2:00PM. I am going to keep my name and identity undisclosed because this is still the internet. I live Arizona and it was a mildly rainy day. My friend and I had been doing some hiking and...

Just wondering if anyone here finds these video/picture leaks about UAP's (Unidentified Aerial Phenomenon) interesting and inspiring enough to try and figure out how they work? Pretty big game changer of technology and would be fun to discuss. I'm hoping at least someone agrees.

Anyone heard/know it? If so, what is your opinion? Real?

Saw this on TV on some channel last night. I thought it was the stupidest thing I've ever heard, but felt maybe there were some supporters or people who have seen a "USO". Cigar-shaped underwater UFOs! They can surface and submerge; grey in color. I wonder what these underwater, or...

Today I was making up some solutions of tin(II) chloride dihydrate (SnCl2.2H2O) and I noticed that an insoluble, yellow chemical had formed at the bottom of the beaker. I have no idea what this could be. I've thought about the possibility that there was an impurity in the tin chloride, but...

Same idea. Have any comments, info, etc. on UFO's, please post here. Thanks.
