@JenkoKent @MickWest 10 meters? We're talking an instantaneous reduction of ~6m/s velocity and you're saying it wouldn't look different? I'd double check the math on that again mate.

@_AstroJoe @MickWest I did — marked in yellow. And you’re exactly right — it’s near perfect. If it lands 10 metres further up field the parabolas wouldn’t look all that different (deflection only alters the course by a few degrees). But the change in outcome is significant.

Panorama-stabilized Norway goal kick, scale corrected, simulating a fixed single camera (created using Sitrec). I'm not seeing anything obvious, but that does not mean there wasn't a contact with the cable

Gravity is constant across the flight of a football in a stadium for all necessary means, drag is not. Magnus force is dependant on airspeed, spin, and spin axis. Your diagram shows a near perfect parabolic trajector... Where is the noticeable discontinuity? You haven't marked where this supposedly happens. Rejecting birds and aliens doesn't make it a wire, you need evidence that a collision occurs.

Gravity drag spin, etc are all constants. A gust of wind strong enough to change the direction of the ball this much in a largely enclosed stadium is essentially an impossibility, and a bird would be visible. I can’t say for sure that an invisible alien race with telekinetic powers didn’t intervene to give England the slightest of edges — but I also have some common sense.

Then I'd say you're by no means in a position to be commenting on the physics of a football moving through the air... Show the exact frame where the ball's velocity and trajectory changes abruptly, and then prove to me that it wasn't due to gravity, drag, spin, win, perspective... until then, a wire is merely a hypothesis.

@_AstroJoe @MickWest Crazy gust of wind, hitting a bird… that’s about all I’ve got haha. Simplest explanation is obviously the best one.

@_AstroJoe @MickWest Yes but shallower on the way down than it should be. Here’s the same with the English player added so you can see him adjusting his run to course correct.

@MickWest Here’s a plot of the ball across your video. The yellow dot is where I see the deflection, and the flight after that seems to obviously decelerate and drop more abruptly than you’d otherwise expect.

@JAtanackov Tis why I admire August 24' storm during my first attempt at meteor astrophotography. Didn't know I needed company through that awful weekend of trial and errors

@landon_wx @JAtanackov Is noctilucent cloud visiblity latitude dependent? How far south have they been seen? (I’m at around 33° N)

@Polymarket Earth is not flying anywhere. The earth is stationary and fixed. The sun and moon circle the earth.

JUST IN: Astronomers say Earth is currently flying through a "debris field" from a hidden asteroid that is breaking apart near the Sun.

@EBagnatori Yeah parallax from the motion of the “space craft” makes this impossible. Take a class on photography clearly you need to.

Now this picture is actually physically impossible to capture at 18,000 mph. This requires an open shutter which with any movement or disturbance will mess up the entire image. No getting past this. This is a test of our intelligence. All the stars should be streaking similar to a normal timelapse taken of Polaris in the opposite direction the “space craft” is moving.

@flyfin588445 @ThreeDeDaniel @JAtanackov It is 400x. The flare classes are based on peak X-ray flux. Power per unit area. Strictly speaking X400 has 400x more power, more energy, more photons. M1 is 10x C1, M1 equivelant to C10 X1 is 10x M1, X1 equivelant to M10 X10 is 10x X1. X100 is 100x X1. X400 is 400x X1.

Fun fact: the 774 AD Miyake event was possibly caused by an X400+ solar flare. This is the original value of X285 +/- 140 in (Cliver et al., 2022) upscaled by the correction in (Hudson et al., 2025). This would be something between a 1000-year and 10 000-year event per (Cliver et al., 2022), but closer to a 1000-year event (with considerable uncertainty).

WHOA… unexpected CME plasma shockwave just hit earth and instantly triggered a level two solar storm. Not sure the source of an 800km/s shockwave… not sure how me, NOAA and NASA all missed that one…

HUGE OPPORTUNITY TONIGHT! Image: Kp Index Forecast Bias/Time NOAA forecasts Kp6... will they continue their underestimation trend? Will their downfall march-on after ~40 near-perfect years for solar forecasting? Will the ongoing magnetic pole shift embarrass them again?

@oldscarf1stweek I got close to the exact same thing that night, and had overwhelming feedback that it was not Steve unfortunately.
