The rotation of Earth’s inner core really has slowed down, a new study has confirmed, opening up questions about what’s happening in the center of the planet and how we might be affected.

Led by a team from the University of Southern California (USC), the researchers behind the finding think this change in the core’s rotation could change the length of our days – albeit only by a few fractions of a second, so you won’t need to reset your watches just yet.

“When I first saw the seismograms that hinted at this change, I was stumped,” says Earth scientist John Vidale from USC. “But when we found two dozen more observations signaling the same pattern, the result was inescapable.

Is it real? Well, it’s a real “arc” reactor that generates plasma, but as we explained in the beginning of the video, it’s impossible to create a device that…

The exact empirical evidence for retrocausality does not exist yet, but the existing empirical data as those from Bell tests may be interpreted in a way to support the retrocausal framework.

Have you ever thought that future states could affect the events that have occurred in the past? Although this idea sounds quite bizarre, it is indeed possible according to a quantum mechanical effect called retrocausality. According to the concept, causality and time do not work in the conventional sense and remarkably, an effect can predate its cause, thus reversing the directionality of time as well.

Usually, in the classical world, this is not what we actually experience. For every cause, there is a corresponding effect, but they work sequentially rather than in the reverse way. Conventional thought process suggests that once a particular event has occurred, there’s almost zero probability that it can be reversed. The physical reason is simple, and it has to do with the arrow of time. In general, the arrow of time points in a single forward direction and this is one of the major unsolved challenges of the foundations of physics because physicists are uncertain of why the nature of time is such.

Most of the fires detected in this map are burning in grass or cropland areas. Reports assert the fires are the result of both large and small-scale farmers attempting to manage the land in the most cost-effective way possible. However, in Angola, 80% percent of farmers are smallholders, which could explain the extensive use of burning practices in the country.

A new study reveals that oxide membranes can confine infrared light to a greater extent than traditional methods, promising advancements in imaging resolution and applications in photonics and thermal management.

Researchers have successfully shown that a particular type of oxide membranes can effectively confine, or “squeeze,” infrared light. This breakthrough could enhance future infrared imaging technologies. These thin-film membranes outperform traditional bulk crystals in confining infrared light.

“The thin-film membranes maintain the desired infrared frequency, but compress the wavelengths, allowing imaging devices to capture images with greater resolution,” says Yin Liu, co-corresponding author of a paper on the work and an assistant professor of materials science and engineering at North Carolina State University.

Waves pick up information from their environment through which they propagate. A theory of information carried by waves has now been developed at TU Wien—with astonishing results that can be utilized for technical applications.
