Hi PhD Tony... I appreciate your knowledge of gravity and your debunking of flat earth nonsense. I need your help... I am discussing the reality of Gravity to a Flat Earther. He pointed out to me that there is a THREE BODY PROBLEM which makes gravity (and the planets rotation) impossible. How would you suggest I answer this fool? Is there a video you did on this (a link)? I need guidance. Thanks.

Thanks Tony for inviting Prof Bell to the debate this evening. Though presumably taxing on your patience and mental health, I suspect the only way you will reach these people is to decease (trigger word) them with kindness. I host several debate forums that focus on debating science denial, and I'm fully aware of how difficult this must have been. It's imperative that we find a way to combat these dangerous ideologies though. You guys are tougher than I am 😅. I spoke to Darryl recently, and he said he will be walking away from this sphere. It's presumably due to Flatzoid suffocating the last bit of empathy that poor man had for this community. Maybe touch base with him, or give him a bit of encouragement? I look forward to more content. You're my primary resource of Flat Earth debunks.

G'day Tony. Love your content mate!

Wonderful set of information.

My kid asked me when you use 2 satelites and their distance to do measurements can you use 2d plane or do you have to use 3d space? I could not answer and i know you can. And i am not a flerf :)

I would like to debate you @PhDTony

Is you're area of expertise seismology?

@PhD Tony you need to have a look at Culture Catz latest videos on an idiot Australian Senator try to science in estimates and crashes and burns.

There is no way someone believing in a flat earth can explain logically why the waves seem to be interrupted by a solid like mass from one side of the planet to the other, except if it were a spherical iron core.

👏👍🙏.

Always love your videos Tony, keep em coming.

Saw your appearance on Modern Day Debate. I'm astonished you managed to get through over 2 hours of talking to those flerf clowns without going insane. I don't think they acknowledged any of your arguments even once.

So....... you are saying that Aussie Open is able to win all their matches due to their use of coriolis?

What is the more terrifying scenario: the Earth rotating in the opposite direction or the Earth stops rotating?

You can't convince people that don't want to be convinced ! And if you and they don't agree that the observations that are at hand are valid, well then there is no basis for agreement . If you belong to a cult, then nothing that outsiders say about the cult is valid within the cult. If you look a flightradar24 you can se most of the airplanes that are in the air right now! you can plot them, and check their departure and arrival times many places. Plot them in on a flat earth - and planes on the southerne hemisphere have to fly supersonic both ways all the time, otherwise they can't follow the times tables !! But they have very normal airspeeds on a globe !

Very well done, and a good refresher for those of us who have studied and performed experiments that the FE bozo's claim haven't been done.

:)

You mean it’s not a Ferrocell image of a magnet? For sooth!

You’ve got flat earthers all wrong here - it’s not that there is no evidence against flat earth, just that there is no evidence they are prepared to accept. Anything that disproves flat earth can only be misobserved, misinterpreted or faked. To a flat earther the Earth can only be flat despite evidence to the contrary - which necessarily has to be false.

I can't argue against this evidence, so I'm going to change the subject to air pressure and containers, even though I've already asked that question a hundred times and ignored every time it's been explained to me. TAKE THAT, NASA!

Thanks Bob.

🤓

I can already hear a 'demonstrable realist' saying these don't count because they are not direct observations of earth's rotation before pointing to a crane and asking how it can be still.

Great Video Tony, Thanks for your time!

Wouldn't it be easier for a flat earther to recreate Reich experiment using a plumb bob on the top of a tall building?

Thanks Tony I would imagine that the leading Flerf's are working on this right now

Flerf response: "Feels stationary to me!" Great to hear your voice, Tony!!!!! 👍👍👍👍👍👍👍👍

Concise, comprehensive, excellent. 😊

You can take a flat earther to logic, but you can't make him think. To them, it's all coloured bubbles and pixie dust.

I am no big expert in the matter but my biggest issue with calling gravity A force in daily conversation is that does not act as one force. Instead this force is different for all objects, depending on their mass and/or the value of G. I would be more comfortable saying "the gravity acting on this particular object is a force".

Fun fact: our techniques for measuring Earth's rotation are accurate enough to measure the impact of Three Gorges Reservoir in China being filled with water in 2008, after the dam was finished.

Gyroscopy requires a container.

Gotta lie to flerf never fails.

Stop trying to use science to disprove flat earth.

This only makes sense if you completely disregard "Nuh uh!"

Loved it Tony! Well done.

Maybe you presented this elsewhere, but to me, the best evidence for a rotating earth is the constant "motion" of the stars. Astronomy has established stars are individual objects at varying distances from earth, so it cannot be claimed that the stars positions are in any way subjective or some kind of illusion. There is no reason for such objects to move in a circle around our lowly solar system, as motion in a circle requires a centripetal force. Furthermore, motion of all those individual objects at different distances would imply an impossible coordination to keep the relative position of all these stars and galaxies constant. Finally, nothing can go faster than the speed of light and that would mean stars and particularly galaxies would have to be going faster than the speed of light to get around such a great circumference that results from a very large distances from earth in one 24 hour period. So if the stars are not moving, then our platform for observing the stars must be rotating. Nothing else makes sense. One can then establish that the earth is a sphere by noting the changes in the angle to the celestial north or south poles with changing north-south position on earth. The mere fact that we can see stars in all directions would not be possible on a flat earth but would the easy on a rotating globe. It also explains the opposite direction of the apparent rotation of the stars around the north and south celestial poles.

Everytime Foucault is mentioned now I always think of that time Anthony Riley looked up the wrong Foucault and did an entire video on it embarrassing himself.

Great stuff. Even a child's toy top starts to precess when it begins to topple. No need for something more complcated. Rotation confirmed.

It's all just coincidence, I say we trust that one guy from the 1800's instead 😂

Great presentation, Tony. Clear and concise. Gotta lie to flerf.

gibbering witsit word salad. lol!

so good. this series is going to be the gold standard for flerf debunks. one thing they always say is "no curvature has ever been measured on the surface of water" or words to that effect. i think "displays convexity upon it's surface" is the catchphrase. level earth observer is always quoting it. i hope you do a debunk of that one.

Excellent video, Tony! I was not aware that Foucault used mechanical gyroscopes to detect the rotation, so that was fascinating. Sadly, none of this will change the minds of the science deniers, but it's really interesting for the rest of us. 👍

Flerfs are always harping on about how we (i.e. normal folk) worship Bill Nye or Neil deGrasse Tyson as the go-to science communicators. Wrong. We worship PhD Tony for this.

Superb, interesting and informative information clearly communicated. Top work Tony.

We of the Witsit's Witless Witnesses (tm) believe that this rotational thingy that you sheep worship doesn't exist! But if it did exist, it would probably be due to a ferrocell and the inertia reciprocating state of the something or other.

its a pity I can't post a "body of evidence" meme here. But to have so many ways that consistently show something is happening that matches reality. Once again Tony has delivered a mining dumper size load of evidence,that obliterates stupidity, worrd salads and running away from the question.

Easy to follow, a little harder to fully understand, even harder to accept if you flerf. But nothing can disprove it. Great video.

Thanks for a clear and concise explanation of ring lasers.
