Interesting, I wonder if this in any way alters the findings of the double slit experiment.
Amazing A new property of light. I guess I've got some study to do, I want to find out as much about this as possible. Being able to twist light in such ways this could be helpful for literally almost every application in which we use light, From the outside shed to holographic displays.
Here is an abstract of the researchers' paper in Science (unfortunately, the paper itself is behind a paywall):
Generation of extreme-ultraviolet beams with time-varying orbital angular momentum | Science
Inside this news release, there is a link to a very interesting short video, in which the researchers explain their findings, with various visual aids:
(I tried posting a direct link to the video, which is .mp4, but for some reason I could not get the link to work on this site.)
I keep waiting for them to discover that red shift is caused by light going long distances and not from primarily from doppler shift.
I wonder if this would be it
I thought redshift was caused by the exponential expansion of space stretching the wavelength of the light. Like a rubber band kind of thing. when stretched in such a way the blue and green are not as pronounced as such long wavelengths, so you tend to get a lot of red. I wonder if this new discovery can be used to benefit gravitational lensing?
