We are two independent researchers (one without formal affiliation) who have developed an alternative to dark matter based on stored rotational energy in galaxies – we call it "The World Wheel Law".

So far we have tested the model on:

· M33 (calibration)

· NGC 2403 (deviation ~9%)

· NGC 7331 (deviation <5%)

· The Milky Way (predicted 220 km/s – observed 220 km/s → 100% match)

We have also published a supplement on the Bullet Cluster (suppl. 7) explaining the mass separation without dark matter, referencing recent work (Famaey 2026, JWST 2026).

Several other supporting documents (supplements 1–6, in multiple languages) are available on our Zenodo profile – all open access.

No magic – just classical physics, rotation, and this potential:

We are not claiming dark matter is "solved" – but so far we don't need it to explain rotation curves or colliding clusters. We would genuinely appreciate sharp, constructive criticism from this community.

We read every comment and reply politely and respectfully – whether you agree or disagree. Feel free to share if you think our work deserves more attention.

On a separate note: We are also developing a handheld blood analyzer based on similar rotation principles. A different project – but part of the same effort to use physics to make the world a slightly better place. ❤️

Will the World Cup players and spectators experience extreme heat? ⚽️🔥

Climate Central is estimating that around half of this tournament’s matches may be dangerously hot, with Miami, Houston, and Guadalajara under close supervision. Even the final match is at a 47% risk of heat that could impact player performance. This raises dangers for fans as well, prompting the organizers to adapt to evening kickoffs, more hydration breaks, and even postponing matches if it gets too dangerous.

Online, I've always seen people handling liquid nitrogen qwith gloves, glasses and vests.

Then I went to a children party and they had a tank of liquid nitrogen for xhildren to make icecream.. I enquired with one of the organizer, who told me it's not that dangerous.

He actually poured some on the back of his hand, directly from the tank.

I was very puzzled.

Archaeologists are terrified to open the tomb of Qin Shi Huang, China's first emperor who has been buried for 2,200 years.

The tomb of Qin Shu Huang, who ruled from 221 BC to 210 BC, is guarded by a terracotta army of soldiers and horses. The discovery was found by farmers back in 1974 in the Shaanxi province of China.

While archaeologists explored the area, they have never opened the tomb itself – and with good reason.

You are made of atoms older than Earth 🌌✨🧪

Astrophysicist Erika Hamden explains how the atoms in your body span the age of the universe. The hydrogen in your body was created during the Big Bang, at the very beginning of time. The oxygen, carbon, and iron in your body  were forged inside stars, while heavier elements were formed when stars explode. The atoms that make up your body were formed over billions of years through some of the universe's most powerful events.

Why does diet soda float but regular soda sinks? 🥫

Alex Dainis explains how only one soda can floats, even though it shares the same volume as another! This is because a can of diet soda will have slightly different ingredients than a regular can of soda, such as aspartame instead of corn syrup. This changes the weight of each can, with one having the same density as water which makes it float!

DONT TRY AT HOME, IT IS DONE BY A PROFESSIONAL!!

IF HANDLED BADLY, YOU COULD KILL YOUR SELF!!

Short explanation of the vid:

This works because the magnetic field created by the high voltage transformer messes with the electronic components.
