Can laser bend space-time?

Laser beams do not curve spacetime. Not because they aren’t powerful enough, but because that isn’t what EM does to spacetime. EM follows the geodesics of spacetime which are already curved by mass.

How do very massive objects affect the spacetime around them?

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

Can lasers affect gravity?

Re: Question: Does laser affected by gravity? Technically, yes, but normal lasers aren’t affected much, seeing as it takes a ton of mass to noticeably bend light.

How does energy curve space?

Since matter carries energy (via Einstein’s famous relation that energy is mass times the speed of light squared), such objects will have a gravitational field and so they will distort space-time. So one way in which a charge or a magnet will distort space-time is by virtue of its matter.

Why do large objects curve spacetime?

Large objects such as the Sun and planets aren’t the only masses that warp the fabric of space-time. Anything with mass—including your body—bends this four-dimensional cosmic grid. The warp, in turn, creates the effect of gravity, redirecting the path of objects that travel into it.

Does a laser curve?

Two years ago physicists demonstrated that a laser beam traveling through the air can bend slightly if certain components are asymmetrical, forming what is called an Airy beam. Now researchers have shown that pulsed, high-intensity versions can leave curved trails of plasma.

How do electromagnetic fields affect spacetime curvature?

Classicalelectromagnetic fields carry energy and momentum and therefore cause spacetime curvature. For example, the EM field around a charged black hole is taken into account when finding the Reissner-Nordstrom and Kerr-Newman metrics.

Are high-energy lasers five years out?

Longtime skeptics of high-energy lasers often say, ‘the technology is five years out… and will always be’. The DoD and defense industry have invested in laser weapons development for 40 years, in anticipation of a transition to troops that has yet to happen.

What are the advantages of laser weapons?

They provide speed of light “flyout” time and have deep magazines – as long as you have a power source, you can fire the laser and hit a target immediately. Lasers also have a very low cost per shot, so it makes sense to use them against low-cost threats like drones.

What is the difference between spectral beam combining and laser matching?

Matching phase corrections can then be applied to individual fiber laser beams comprising the high-energy laser beam, correcting for the distortions in that high-power laser beam. Spectral beam combining provides a simpler technique for generating low to moderate power level laser beams (up to ~50 kW-class).
