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.

The ability to speak clearly, succinctly, and powerfully is easier than you think
The ability to communicate effectively can make or break a person's assessment of your intelligence, competence, and authenticity.
The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
