Japanese university sets world record with an insane 2 quadrillion-watt laser burst

Add as a preferred source on Google

In news news that we’re sure super villains everywhere will be thrilled to hear,  scientists at Osaka University in Japan have reportedly fired the world’s most powerful laser beam. To do this, researchers used the university’s massive, 300-foot LFEX (Laser for Fast Ignition Experiments) to blast out a 2-petawatt burst (2,000,000,000,000,000 watts) — allegedly the largest burst ever achieved.

Two quadrillion watts is, without question, a ridiculously large amount of output. But the thing is, the laser didn’t actually emit that many watts for very long. The burst only lasted about one picosecond (1/1,000,000,000,000 of a second), so while the LFEX’s output was incredibly large, the actual amount of power (energy divided by time) it used wasn’t all that big. When it was all said and done, the laser only produced enough power to run a microwave for about two seconds.

That makes it sound pretty weak, but just take a second to consider what that means. This laser fired for one trillionth of a second. That’s not even enough time for light to travel a full millimeter — but in that minuscule stretch of time, the LFEX emitted enough energy to warm up your breakfast burrito for two full seconds. That’s ridiculous.

And the researchers aren’t stopping there, either. “With heated competition in the world to improve the performance of lasers, our goal now is to increase our output to 10 petawatts,” said the institute’s Junji Kawanaka, an associate professor of electrical engineering at the university.

 

Unfortunately there isn’t a video of the LFEX being fired, but if you need a better explanation of how all this craziness works, we highly recommend checking out the above video from University of Texas at Austin — the previous world record holder, and first organization to produce a 1 petawatt laser burst.

Google built an AI that can see football plays before they happen
DeepMind’s latest research predicts player movement up to eight seconds into the future
Google Deepmind TacticAI Featured

Football managers spend countless hours analyzing corners, free kicks, and player positioning in search of tiny competitive advantages. Google DeepMind believes artificial intelligence can make that process significantly faster, and its latest project, TacticAI, is designed to do exactly that. TacticAI is a football-specific AI assistant capable of modeling player movement, forecasting future play dynamics, and even recommending tactical adjustments for corner kicks. One of its standout abilities is predicting player trajectories up to eight seconds into the future using only broadcast-style visual data.

TacticAI was built with Liverpool FC and validated by football experts

Radical new coffee-making method uses sound, skips hot water and reduces energy bills
UNSW reserachers brewed espresso with room-temperature water and ultrasonic sound waves, cutting energy use by 75% in blind tests that fooled 100 regular drinkers.

Researchers at UNSW Sydney have figured out how to brew espresso-strength coffee without heating any water. The method replaces hot water and high pressure with ultrasonic sound waves, and in blind taste tests involving 100 regular coffee drinkers, participants could not tell the two apart.
