Neutrino observatories show promise for detecting light dark matter
Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of the universe's mass. Over the past decades, many physicists worldwide have been trying to detect ...
Quantum clues to consciousness: New research suggests the brain may harness the zero-point field
What if your conscious experiences were not just the chatter of neurons, but were connected to the hum of the universe? In a paper published in Frontiers in Human Neuroscience, I present new evidence indicating that conscious ...
Ghostly solar neutrinos caught transforming carbon atoms deep underground
Neutrinos are one of the most mysterious particles in the universe, often called "ghost particles" because they rarely interact with anything else. Trillions stream through our bodies every second, yet leave no trace. They ...
