@Ann K technically, that's still 2020 Election news?

Looks like you're all set to start your own UFO channel! :-p

well, first I would ask for evidence for this claim, specifically that a) this total travel time reduction is possible in practice, on domestic routes (and for the US, not transcontinental—above a certain length the aircraft wins)—remember luggage! b) the total cost for society per...

Good place for extraterrestrials to go undercover? ;)

Starting off early (excerpted): The evening before Michigan's state primary, Wayne County GOP leaders held a Zoom training session for poll workers and partisan observers -- warning them about "bad stuff happening" during the election and encouraging them to ignore local election rules barring...

It's possible that the holes in the sides of the deck body that accomodate the handrail slots actually weakened the deck and caused the collapse.

they're still perpendicular on the other side? near side at 0:05 The deck body seems deep enough to resist bending (and the handrail clearly doesn't), my guess is that it consists of two sections that were inexpertly joined. Some stress then overloaded that joint, and the sudden jerk from...

You literally get a side view of the curve any time you look at the ground. The problem is that the curvature is so very slight. Some wide enough communicating pipes installed next to a LIGO arm might actually be doable and interesting. Yes. Obviously the pendulum only shows directly that the...

why else would it collapse? someone below dislodging a support? I'd handwave this away with vibratory mode not anticipated by the builders. triggered by the sharp impulse from releasing the tension on the handrails—sort of like the amateur version of the Tacoma Narrows bridge failure.

kite stacking means flying several kites off the same string. Youtube has examples. (It's not important to this discussion.)

looks like a plane on opposite course, at extreme end of sensor resolution (low incormation zone), with image processing applied in-camera further obscuring the shape and providing the black halo. With an exact time & location, it'd probably be easily identified from the flight tracking, and...

That disagreement seems mostly irrelevant for this discussion? as all four structural analyses can be summarized as "heat caused various things to go wrong, then column 79 failed, then progressively the core collapsed, and then the exterior". Our discussion here seems to be concerned with what...

You're not being persecuted and "stigmatised" for coming forward with UFO reports. If these guys who earn good youtube money from this (or plan to) want to keep receiving material, they need to visibly encourage everyone who is not quite sure what they have seen, because that's most of the...

Wolfram Alpha gives g=9.80213m/s² for Manhattan.

Which is nice. Some reports got debunked and stayed big anyway.

Take a broomstick. Rest one end on the table, hold the other end away from table, and let go. • The broomstick undergoes "gravitational acceleration", because it falls down due to gravity. • The broomstick is not in free fall, because one end is supported. • Parts of the broomstick close to...

There's a number of Foucault pendulums installed around the Earth, they still don't believe it rotates. And that's a much more obvious demonstration than your 2m on 10 km sagitta that nobody can verify without tools. You might as well paint a straight line on the side of the Pontchartrain...

You're suggesting a modern reimagining of the 1838 Bedford Level experiment (wikipedia), that resulted in an 1870 bet that ended with a court case and a Flat Earther imprisoned for threatening to kill the surveyor who won the bet. A similar experiment was conducted by Jeranism in 2017 or 2018...

If their model worked, it wouldn't be public—they'd keep it secret and get rich off it. Is anybody quoting these models to sell something? If they had some kind of actual impact, it'd be more likely to be a scam, and not just a hobby. As it stands, at best they might be earning research grants...
