As a PhD mathematician, I do believe the this Antarctic theory of the OP's friend is improbable and almost certainly untrue. The maths just does not work if the OP's friend was correct. For those on this thread who have gone to Antarctica, then this appears to verify its untruth.
But, as for your comments on digital ids and conspiracy theories, I think you are wrong. If the WEF are openly stating these are their aims, televise lectures with this draconian lunacy, and heads of state and royalty are going every year to Davos to bend the knee to these nutjobs, then it clearly is NOT a conspiracy.
Just because you do not choose to read/view it does not make it unreal or a conspiracy. In fact, the opposite is true and you are the conspiracy theorist for ignoring evidence that says your ideologic viewpoint is wrong.
Digital Ids will not stop the boats as Keir claims. Its lunacy to think it will. Why are those with left-leanings wanting ids, but those opposed to mass immigration on the centre or right oppose ids?
Do not expect the BBC or others to tell you the truth. We hear every day from Kier and the BBC news how Labour have a massive mandate from the public. But this is not true, using the official government figures.
Only 20% of the total electorate voted for Labour. This is a provable truth from government figures. A massive 80% of the total electorate did not vote for Labour. Kier has no mandate at all to do anything. And, he is even losing support from these people who did vote for him.
There is an official petition against the Digital Ids. Since petitions only typically get less than 100,000 signatories, the present 2.8 Million is massive. I cannot presently find the figures myself, but this is alleged to be between a quarter and a third of the number of people who voted for Starmer and Labour at the last General election. So, the millions for this petition are massive and staggering.
If you are opposed to these Digital Ids, I strongly advise you to sign it while you can. Digital Ids have no purpose, but for unsavoury government activity.
