On your last point, lunar orbiters have observed and photographed most of the lunar surface, some of it in high resolution - at least good enough to show the traces of human landings. No indications of non-human landings have been found. Unless of course the mysterious 'they' are hiding the...

One point against 'alien visits' that isn't often mentioned is the lack of evidence for non-human landings on the moon. If even a small fraction of alleged alien visits to the earth are genuine, the aliens seem to have a great curiosity about events on earth. So what could be more natural for...

The original video was supposedly taken in 2011. The placard visible at 0:09 and 0:32 shows a number 12-06-11, which could be the date (in British style) 12 June 2011. I do wonder why these old UFO stories get endlessly recycled. Aren't there enough new ones? The film was supposedly taken...

I was browsing through another UFO thread when I noticed an IR photo of a UFO/UAP filmed from police helicopter in Britain which looks strikingly like the Omaha one, i.e. a black spherical blob! In that case it was speculated that it was a 'chinese lantern', but also stated that it was 'moving...

Surely that is far too large. Even if the object is down by the water, it can't be more than a few meters across, or smaller if Edward Current's simulation, linked at #8 above, is correct.

If you had a hypothesis that a pendulum would swing indefinitely, then if it came to a stop the hypothesis would be falsified. Since no-one has proposed such a hypothesis the fact that it comes to a stop does not make it a failed experiment. But I think we have all spent/wasted enough time...

Foucault's Pendulum doesn't require an electromagnet to demonstrate the rotation of the earth. If left to swing indefinitely it would gradually slow down due to friction and air resistance, like any ordinary pendulum, so in public museum examples it is often 'tweaked' by an electromagnet to...

The apparent linear size of an object is inversely proportional to its distance from an observer, so an object 12 m long at a distance of 6,000 m (not km!) would appear the same linear size as an object 2 mm long at a distance of 1 m. That's about half the size of a grain of Basmati rice held...

The main atmospheric gases (nitrogen, oxygen and argon) don't emit much IR radiation, even if they are very hot to the touch, or to a thermometer. The jet exhaust gases themselves will contain a lot of CO2, H2O, and other compounds such as nitrous oxide, which do emit IR. So as they leave the...

I'm sure someone has already pointed this out, but in the course of 34 seconds in the video the direction of the FLIR scope changes from 54 degrees L to 7 degrees R, a total change of 61 degrees and an average change of 1.794 degrees per second. Of course this does not simply equate to the rate...

Evidently I was even more confused than usual. I knew that the camera was turning to the right, relative to the axis of the jet, but the jet itself is turning rapidly to the left, and the net effect, as seen from a 'God's-eye-view', is that the camera is turning to the left (i.e. counter...

If you haven't already seen it, you might like this video about the reasons for 'lift' by a professor of physics at Nottingham University. I haven't watched it again, but I remember finding it interesting. I see that I commented on it 3 years ago when I first saw it! Source...

Surely the sun is behind it, or slightly to one side (in the top photo of #143)? The left side of the balloon - sorry, the unknown object - is catching the sun, but the front is in shadow. Also, the image of the object is blurred, due to motion, limits to resolution, or some combination of...

Thanks for the comments and examples. If I ever deploy the argument in a wider forum I will try to guard against the misconception you mention. As you say, 'more distant' does not imply 'more focussed'. My point, which I hope still stands, is that if an object is well focussed at 5 miles, it...

People on Twitter, etc, still keep arguing that you can't have two objects at different distance in focus at the same time. I was trying to think of a simple general argument against this. Do people here think the following is (a) valid and (b) convincing? 1. In any optical instrument with...

I was rather expecting Chris Lehto to come back saying: 'Aha, but you can't trust the banking angle shown on the screen. Any expert pilot knows that isn't reliable. ' I don't think he has (yet), but be prepared! The UFO enthusiasts increasingly remind me of the flat-earthers. If you...

The video at #263 was filmed from one side of Lake Pontchartrain in Louisiana, and shows a plane descending to New Orleans airport on the other side of the lake, about 25 miles away. Most of the 'descent' really is descent in altitude, and not just 'following the curve of the earth'. The film...

I guess the plane must have had a cold nose. Improbable at 20,000 feet, I know.

What radar returns? Chris Lehto seems to think there weren't any (for the Gofast object).
