it looks more confusing than it is!

One of physicists' most popular recent idea, that entanglement is really evidence for wormholes, just died

Nuclear Fusion startups are running into trouble.

here is the video on the Riemann hypothesis that YouTube took down

We are seeing the first signs of AI improving itself

America is coming for one Europe's most important (if not THE most important) technologies

A group of physicists have calculated that quantum mechanics allows sending messages into the past. I've had a look at the paper.

String theory didn't just fail, it's far worse.

I am optimistic that we will one day make contact to extraterrestrials because I don't think that the speed of light is a fundamental limit. Here I explain why and I have a brief summary below.

Astrophysicists have found evidence of UAPs in old photographic plates. Something seems to have been orbiting around our planet before we had satellites! This finding has been independently confirmed. Still, scientists are afraid to speak out. Beatriz Villarroel Rizwan Virk

Physicists are rethinking dark matter. But not like you'd expect.

A mathematician has come up with a new way to derive all mathematical operations from merely one. I've had a look at the paper.

Astrophysicists have discovered a Giant Ring in space. But the maths says that it shouldn't exist.

8 scientists in the US, involved with classified space-related research have disappeared or died in the recent past. I had a look at what is going on. It is definitely... odd.

It is not every day that I can tell you about a new explanation for the origin of the universe -- and the origin of time itself -- that is not complete bogus. But recently physicists have come up with one that works because it removes the problem of quantum gravity.

A group of physicists say they've proved that quantum mechanics can be explained without quantum mechanics. I asked ChatGPT, Grok, and Claude what they think about the paper.

I had a look at the recent claims that breakthroughs have been achieved in cold fusion.

The chances are increasing that we are headed into a Super El-Nino phase of the climate. Here is what the forecasts say and what it means.

Is China the new leader in green energy or a record polluter? I have collected the relevant number and think the answer has less to do with being green and clean and all to do with progress.
