Manipulating Space-Time with Lasers

In summary, changing the curvature of space-time around a powerful laser beam can be achieved by using pp-wave spacetimes and specifically the Bonnor beam solution. Additionally, any rotating object can also cause a "drag" in space-time. It is important to note that in this context, "lame" refers to the curvature of space-time and not a physical disability. Further information can be found on the effects of rotating masses and coordinates on space-time.

How to change the curvature of space-time around a very powerful laser beam?

Look up pp-wave spacetimes, particularly the axisymmetric pp-wave spacetimes.

Spinning disk

Thank you for your reply but I have another question
How lame space time around a rotating metal disk?

Thank you.

"lame" I mean curvature of spacetime.

I am sorry but this text translate Google from Slovak languige.

Hi jaiii ! :smile:

Any rotating object "drags" spacetime around with it …

see http://en.wikipedia.org/wiki/Frame-dragging" :wink:

btw, "lame" means unable to walk properly ("he is lame", "he has a lame leg" "lame-duck president"), and also is used figuratively to mean something that doesn't work properly ("a lame excuse") :smile:​

In addition to the information about how a rotating mass affects the curvature of spacetime you may want to read about how using rotating coordinates affects things in the absence of a rotating mass:

1. What is "manipulating space-time with lasers"?

"Manipulating space-time with lasers" refers to the use of laser technology to control and alter the fabric of space and time. This concept is based on Einstein's theory of relativity, which states that space and time are interconnected and can be manipulated by energy and matter.

2. How do lasers manipulate space-time?

Lasers can manipulate space-time through a process called gravitational lensing. This involves using the intense beams of light from lasers to create a gravitational field, which can bend and warp the fabric of space and time. This effect can be used to create wormholes, time dilation, and other phenomena.

3. What are the potential applications of manipulating space-time with lasers?

There are many potential applications of this technology, including time travel, creating artificial wormholes for space travel, and studying the effects of extreme gravity on objects. It could also have practical applications in fields such as communication and navigation.

4. Is manipulating space-time with lasers possible?

While there have been experiments and theories that suggest it is possible to manipulate space-time with lasers, it is still a highly theoretical concept that has not been fully proven or achieved. The technology and understanding required for this level of manipulation is still in its early stages.

5. Are there any potential risks or consequences of manipulating space-time with lasers?

As with any new technology, there are potential risks and consequences that need to be considered. The manipulation of space-time could have unintended consequences on the laws of physics and could potentially disrupt the delicate balance of our universe. It is important to continue studying and researching this concept to fully understand its implications.
