Laser Beams Deflected Off of Nothing but Air for First Time Ever in Breakthrough Patent Pending Process - The Debrief::An international team of scientists report that they have successfully used acoustics to deflect laser beams in an engineering first.
Horseshit. Don’t piss on my head and tell me it’s raining.
Edit: this is more horseshit like the “room temperature superconductor” that was instantly debunked as a horseshit scheme recently.
Sound pressure waves cannot distort spacetime
Green laser beams have been deflecting off nothing but air since we invented green lasers. That’s why they are visible without adding smoke.
I mean, that’s a 20GW laser, what about those handheld lasers? Would you still need 140db?
Space battles would be so much cooler if every now and then the phaser gets split around the ship instead of hitting the shields.
Would also work even when shields are down.
Doesn’t need to be air “in space”, there just needs to be air somewhere between the laser weapon and whatever it is you don’t want the weapon to destroy…
… although it’d probably be easier to use a mirror. Maybe one pointing directly at the person holding a laser weapon. ;-)
Damn… you’re right.
Maybe they’ll find another way now that they’ve found one.
140 decibels. I’m sure some applications exist but it won’t be a 3D TV soon.
In an ultrasonic frequency we can’t hear. But your pets and any nearby bats or rodents etc may be upset by it…
Yes. Industrial grade ultrasonic sensors are harmful to your health. They can be used, for example, to measure the water level in a tank. If you need to enter a place like that, you should physically disconnect the sensor first. You might not hear much of the noise, but you may feel it in your teeth or some other places.
I didn’t know the answer to this so I looked it up - yes. Over 120 Db can cause damage even if it’s ultrasonic and you can’t hear it. Apparently at 155Db the heat created by the sound wave can be dangerous as well.
