In 2023, physicists found the gravitational wave background that’s made by supermassive black hole collisions, teleported quantum energy in the lab, and puzzled over JWST’s potentially cosmology-breaking discoveries.

00:05 Low-Frequency Gravitational Waves
When galaxies collide, their supermassive central black holes merge — a smashup so violent that it shakes the very fabric of space-time itself. In June, multiple international collaborations announced that they had found the resulting gravitational waves that alter the apparent rhythm of pulsars.

04:23 Quantum Energy Teleportation
A quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works, effectively borrowing energy from a distant location and thus violating no sacred physical principles.

08:46 Discoveries from the James Webb Space Telescope
The first round of big results from observations made by the James Webb Telescope were released this year, including observations of light from galaxies that glowed some 300 million years after the Big Bang and an abundance of supermassive black holes.
