    Claim: Ancient Cultures inherited Structures and Artefacts from Pre-Historic Lost Civilizations with Advanced Manufacturing Capabilities

    Thanks! My favorite channels, are https://www.youtube.com/@WorldofAntiquity and another good one is https://www.youtube.com/@AncientArchitects. Both are 100% science backed and no chance for woo woo woooo

    Claim: Ancient Cultures inherited Structures and Artefacts from Pre-Historic Lost Civilizations with Advanced Manufacturing Capabilities

    Came across a video about Egyptian artisans that try to keep the crafts alive. Check this part (t=1852), about stone vases.. Source: https://youtu.be/8e0G51TYHy8?t=1852

    Mosul "Sphere"

    Mendel is right. If you place another lens (your eye) in between the other lens and its focal point, you get a upright image. I guess i was ignoring that as the droplets have such a small focal length. So i removed/striped my former comment..

    I am missing in their story the roundness of the shape(s). The only one they mention is the inside of the neck. If they claim the neck roundness deviates only by 0.001" (25 micrometer for normal people) from a perfect circle, I am pretty impressed a actually. Impressed by workmaship, and indeed...

    Mosul "Sphere"

    Hmm, not entirely correct. There can never be a real image when "the observer is between the lens and the focal point". Hence, an image as observed through a lens is always inverted.

    I have worked with large XYZ sample sets, pointclouds (laser scanned) of (mainly) precise mechanical objects for a number of years, so I know exactly what they are doing. The creation of a reference frame based on the centre of the top of the vase is logical, and also the flat on top as the...

    Solved: A Balloon-Like Entity near Sutter Buttes, CA is a Graduation Balloon

    @flarkey After wondering for 5 minutes where those phone sounds come from... I realise the person of the video has not seen the evidence as presented by you and Mick. Nah, of course not. He is probably just ignoring it, to maintain a good story. A wrong story though.

    Solved: A Balloon-Like Entity near Sutter Buttes, CA is a Graduation Balloon

    I think @deirdre was the first to coin the Hassle balloon! Congrats, good work. This is got to be the nail in the coffin, I cannot imagine a hardcore ufo person is still going for a craft from ZentaurX. On the other hand, knowing reddit.. :)

    Mosul "Sphere"

    @Z.W. Wolf I am not convinced at all about your theory of radiometric correction as mentioned in your post 66. Not only is this only needed when doing science (observation, spectrometry) which is clearly not the case in that warzone, but also you don't create a reference to do this in the...

    Mosul "Sphere"

    @Z.W. Wolf I agree with your comments, it is in my view also impossible for a long focal telescope to have an object in (rather) focus, that is that close. It is related to the f/#, and the hyperfocal distance is usually tens of meters for systems of f/11 and up.

    Mosul "Sphere"

    @Itsme Not sure if I can agree. The angular size of the ground is not the same as our "ufo", they are at different object distances wrt the camera lens. We cannot determine from the picture alone, the actual size of the droplet/ufo/etc, I believe.

    How to see deployed Starlink "Racetrack" flares

    Note the imidiate "pavlov" wrong assumption in the tweet, of it impossibly being satellites:

    Explained: Chilean Navy "UFO" video - Aerodynamic Contrails, Flight IB6830

    When looking in the document called "INFORME GEIPAN EN INGLES", the experts conclude it is likely a jet airliner. Who is still doubting it? I guess the ones that put question marks everywhere are YouTubers, as they have something to gain from discussing cases endlessly. Link...

    UFO Formation Observed over Santiago

    I agree with @flarkey, and also the older thread where we and @Easy Muffin made a similar comment. It looks like aircrafts in formation and later curving away. They are either approaching (headlights) or moving away (engines)

    Skinwalker Ranch Carriage House Lights and Bird on a Sunny Day

    SirOaktree, cool company name. I am sure it is because the owner's name is VanEeckhoutte, which is an old Belgian/Dutch name meaning oak (eikenhout).

    Video Needs Debunking: Incredibly Fast Bigfoot Jumping from Tree & Running to Cover

    It looks a little too blurry to me to be an object close to the tree, which is in pretty good focus. Perhaps the "Sasquatch" was a little smudge thing on the front window from the skid loader.

    Skinwalker Ranch Carriage House Lights and Bird on a Sunny Day

    So, do we agree the lights in the video (subject of this thread) to be: 1) faked? or 2) a coincidental reflection from bug or web taken as "evidence"? I don't believe their stories, nor do I see evidence.

    Skinwalker Ranch Carriage House Lights and Bird on a Sunny Day

    Not if you want to keep it all a "mystery". Look at it, they deliberately keep an old crappy dusty shack for "finding anomalies".. Of course dust and insects and other stuff will show up, making me believe their real goal is to NOT find out.

    Las Vegas UFO - Lights in Clouds Above The Strip [Light Pillar Map]

    @taivaantuntija Perhaps good to start a fresh thread on this one. I looked on google maps and streetview, and there are a whole bunch of very very high cranes in the proximity. My guess is someone attached some lights/beams or even a moving one on one of those cranes, likely because of Xmas.

    Searchlight "UAP" in Wisconsin - Flanders Family Christmas Lights

    These ones are so cool, with the carbon rod HV discharge sources! Must have been not only an optical (lightlevel) hazard, but also you can get zapped using them..
