    "GO FAST" Footage from Tom DeLonge's To The Stars Academy. Bird? Balloon?

    Again, the TTSA release has made the main-stream news. Here is an opinion by Christopher Mellon, published in the Washington Post, ignoring all research that has been done since December...

    Sergei Skripal 'Nerve Agent' Attack

    To me, the likeliest explanation is a glaring signal by the Russian government to their own citizens that no one will be ever safe after providing secret information to foreign powers. There may be even the useful side effects of being able to test the real-world release of a new chemical...

    "GO FAST" Footage from Tom DeLonge's To The Stars Academy. Bird? Balloon?

    A very short FLIR video of a flying bird against sky and ground, from a freely available dataset provided by Oklahoma State University. https://www.metabunk.org/attachments/birdnear-avi.32202/ The appearance of the bird is ambiguous at least. Even against the sky it's not a significantly warm...

    "GO FAST" Footage from Tom DeLonge's To The Stars Academy. Bird? Balloon?

    The black/white thing is not helping much, unfortunately. A bird against the open sky will most certainly show up 'warm'. https://www.sciencedirect.com/science/article/pii/S1574954115001478 When a warm object, such as an animal, is in the thermal camera's FOV, it appears as a bright blob in...

    Sergei Skripal 'Nerve Agent' Attack

    A revenge execution after such a deal (and indiscriminately affecting innocent people) is not generally agreed upon to be a "part of the game". I've not heard about Western nations' services being involved in revenge killings of exchanged spies in Russia. It would only make sense if it became...

    Debunked: High Bypass Turbofans do not make Contrails [actually they make more]

    A turbofan does not create less water in relation to the amount of fuel it uses. It burns (converts) the fuel more completely so it may even create a little more vapor than a legacy jet engine - always in relation to the fuel intake. The thermal argument is central. The required time for the...

    Why Do Sagging Floors or Trusses Pull Walls Inwards

    That's likely aided in parts by the slight rotation of the 'cross beam' between the nails. Its lower edge is pushing against the outer nails

    Explained: Mysterious lights over Milwaukee [Seagulls, Night Exposure Trails]

    I think the issue is rather the night situation and the exposure of the camera. The brightness level in that stream is 'unnaturally' high. A still with that setting would need a long-time exposure, and indeed the excerpt in question looks like a movie sequence of long-exposure images (as seen...

    Is Operation Northwoods a hoax? [No, but it's not an "Operation" Either]

    Is it possible that this should read May 1962 instead?

    Marjory Stoneman Douglas High School shooting

    Somewhat off-topic, the "Hogg in California" video led to a political aid being fired: https://www.washingtonpost.com/news/politics/wp/2018/02/20/a-lawmakers-aide-called-school-shooting-survivors-actors-within-hours-he-was-fired/ According to the Tampa Bay Times, Kelly sent an email to the...

    Water Level Showing Mountain and Horizon Dip Due to Curvature

    My question is - regardless of the direction - why sunlight would bend at all on a flat earth. As far as I understand the FE models, the sun is somehow supposed to be either inside the atmosphere or very close outside of it. In any case, when it's close to the horizon, its light should not have...

    Water Level Showing Mountain and Horizon Dip Due to Curvature

    Atmospheric refraction makes the horizon rise, or doesn't it? So if we'd hypothetically subtract its influence, the distance from water level to horizon would even be larger. Furthermore, the effect of a rising horizon due to atmospheric refraction works only on a spherical (or cylindrical)...

    Falcon Heavy First Launch - Vertical Rocket Contrail

    At least one photo captured the (partial) trail of the Falcon Heavy during launch. As in other rocket launches, it visualizes different conditions in atmospheric layers at different altitudes. There will likely appear video material about the launch that clears up the question if the trail...

    Explained: Unburned trees next to burned down structures as evidence of secret "energy weapons"

    There's more than one possible cause why a tree is becoming hollow. Usually, when the bark is hurt, there are indeed fungi that can penetrate it (more like the German "Schimmelpilz" than real mushrooms). They can lead to the tree dying from the inside. Regarding redwood trees, there is a...

    Perspective on the popularity of conspiracy theories.

    In my view, this is a point worthy of bringing up with believers, right at the moment when they claim "overwhelming evidence". Remind them about how Youtube suggests video after video once they click something about a conspiracy (or indeed about any issue) for the first time. My impression is...

    The Ariel School, Zimbabwe UFO sighting - has it ever been debunked?

    Possible, yes - but likely? What is the simpler explanation? Suggestive questioning and teacher-student attitude or a visiting alien craft seen only by a minority of children in presence? BTW, if real there would have been multiple events, as the descriptions were quite differing.
