Is the Era of Dark Matter Over?
Mysterious dark matter and dark energy may no longer be needed to explain the Universe's accelerating expansion, which may be caused by tension between matter and antimatter.
What's the Latest Development?
CERN physicist Dragan Hajdukovic has written a striking new paper than explains the universe's accelerating expansion in terms other than dark matter and dark energy. By combining the idea of a quantum vacuum with gravitational repulsion between matter and antimatter, Hajdukovic has arrived at an energy density consistent with the cosmological constant, the force which is causing the Universe's accelerating expansion. This new energy density is at least 30 orders of magnitude larger than the observed dark energy density.
What's the Big Idea?
An interesting difference between Hajdukovic's theory and the standard cosmological theory is that the latter predicts the expansion of the Universe is decreasing, which is at odds with astronomers' observations. Whether Hajdukovic is right about opposing gravitational forces between matter and antimatter could be determined by experiments at the CERN physics laboratory in Europe, which is where Hajdukovic incidentally works. CERN's AEGIS experiment is currently working to determine the properties of antihydrogen.

Is it "perverseness," the "death drive," or something else?
Eight-dimensional octonions may hold the clues to solve fundamental mysteries.
- Physicists discover complex numbers called octonions that work in 8 dimensions.
- The numbers have been found linked to fundamental forces of reality.
- Understanding octonions can lead to a new model of physics.
It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.
- It's an all-hands-on-deck moment in the arc of civilization.
- Everyone has a choice: Do you want to try to earn enough money to insulate yourself from the world you're creating— or do you want to make the world a place you don't have to insulate yourself from?
