Physicists Just Found a Quirk in Einstein's Predictions of Space-Time
1 天前 · But a team of researchers has just found that the predicted curvature of space-time calculated using relativity does not always quite match up to what we observe, using data from the Dark Energy Survey that is currently mapping hundreds of millions of galaxies across the cosmos. That doesn't mean there's something broken – but it does suggest that there may be something out there that we ...

Fusion Breakthrough: 6 Minutes of Plasma Sets New Reactor Record
2024年5月7日 · For fusion to happen on Earth, the fuel needs to reach at least 50 million degrees Celsius. One of the main obstacles fusion power faces is that it takes a tremendous amount of energy to generate those extreme temperatures, and, so far, reactors can't sustain a plasma long enough to gain an energy surplus that could be put toward commercial use. So, for now, fusion reactors typically consume ...
It's Confirmed! Laser Fusion Experiment Hit a Critical Milestone in ...
2024年2月6日 · In the case of this particular fusion technology, that heat is delivered via a powerful burst of light. The experiments involve bombarding a capsule containing a measly 220 micrograms of deuterium and tritium fuel with 192 high-powered lasers, which raises the pressure to 600 billion atmospheres and the temperature to 151 million °C (272 million °F).
Updated: A Major Neutrino Announcement Is Happening Today
2023年6月29日 · "For example, electromagnetic radiation does not provide a picture of the Universe any earlier than the time of last scattering (about 400,000 years after the Big Bang). Gravitational waves, however, can give us information all the way back to the onset of inflation, just ∼10-32 seconds after the Big Bang," theoretical physicist Susan Scott of the Australian National University and the ARC ...

2024年8月22日 · Geomagnetic storms can spark beautiful aurora borealis and aurora australis – the Northern and Southern lights. These colorful displays have been showing up further south than usual, in states like Texas and Colorado. That's because of the Sun's increased activity. A beautiful display of the Northern Lights in Alaska.
