Black Hole Merger Supports Hawking's Theorem

Astronomers announced on September 17, 2025, the detection of a black hole merger that provides strong evidence for Stephen Hawking's area theorem. Observed via gravitational waves, the event aligns with predictions that black hole surface areas cannot decrease. This bolsters fundamental physics theories amid ongoing cosmic explorations.

AIP Previews Week of September 15, 2025

The American Institute of Physics outlines key events and developments in physics for the week of September 15, 2025. The preview includes policy updates, conferences, and research highlights. It aims to inform stakeholders about upcoming opportunities in the field.

Black holes may explain 60-year cosmic rays mystery

Scientists at the Norwegian University of Science and Technology propose that winds from supermassive black holes could accelerate ultra-high-energy cosmic rays, solving a puzzle dating back to 1962. These particles, mostly atomic nuclei, reach energies up to 10^20 electron volts. The hypothesis suggests these winds, moving at half the speed of light, fling particles across the cosmos.

Scientists uncover hidden energy mechanism in M87 black hole

Astrophysicists at Goethe University Frankfurt have simulated how the supermassive black hole M87* powers its massive particle jet using a new numerical code. Their findings reveal that magnetic reconnection, alongside the traditional Blandford-Znajek mechanism, extracts rotational energy from the black hole. This discovery explains the immense jets that influence galaxy evolution.

A team of physicists has created visible time crystals, a new state of matter that repeats in time rather than space. This breakthrough allows for observation with standard lab equipment. The invention was detailed in a paper released today.

Electrons in graphene reach supersonic speeds for first time

Researchers have achieved a breakthrough by pushing electrons in graphene to supersonic speeds, creating a hydraulic jump similar to a sonic boom. This experiment, conducted using a microscopic nozzle, marks the first observation of such electron behavior. The findings could help resolve debates on electrically charged shockwaves.

Trio awarded 2025 Nobel Prize in Physics for quantum tunneling work

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel Devoret, and John Martinis for their pioneering research on quantum tunneling in superconducting circuits. Their 1985 experiments demonstrated how quantum effects apply to complex systems, laying the foundation for modern quantum computers. Clarke expressed surprise at the recognition, noting the unexpected impact of their discovery.
