Instagram is currently testing a new feature that will allow users to access your recently shared reels. Users will find it simpler to reshare a reel that they enjoyed with another friend at a later time as a result of this change. Amazing, right?
The New Feature
An account shared a post regarding the new feature. This gave the impression that Instagram is displaying a row at the very top of your direct messages with the label Latest Shares. The screenshots that were uploaded by the account show that shared posts will also display the avatars of friends whose reels you have shared with them. If you shared the same short video several times with different friends, it will only display it once using the avatar of the person you most recently shared it with.
A spokesperson for Meta told the channel that the company was in the process of pushing out enhancements to the way users can search for and rediscover reels that have been previously shared in chats. Nevertheless, Instagram didn’t indicate whether this feature displayed other posts in the newest shares area that are not related to reels. In addition, it did not provide any info regarding the rollout schedule.
Instagram’s Focus on Short Videos
Instagram’s exclusive focus on reels over the past few years makes it hardly unexpected that the platform does not support other types of posts. Last year, it was stated that all videos under 15 minutes would be posted as reels. The purpose of this new test is to encourage you and your friends to regularly share and enjoy short videos. You see a funny post, you share it with your friends. Then, they open the post, swipe up to view more, and they see more videos.
Last week, Meta announced that they were discontinuing the creator reward program for reels in favor of ad revenue sharing and other revenue strategies.
Famous Einstein Equation Is Used to Create Matter from Light
According to Albert Einstein’s famous E=mc2 equation, if two suitably energetic photons, or light particles, collide, matter in the form of an electron and its antimatter opponent, a positron, should result.
However, the process that was discovered by Einstein, which was first described in 1934 by American physicists Gregory Breit and John Wheeler, has long been one of the most difficult to observe in physics, because the colliding photons would have to be highly energetic gamma rays, which scientists have yet to create. Alternative experiments have demonstrated the production of matter from many photons, but never in the one-to-one ratio required to confirm the phenomenon.
However, experts at the Brookhaven National Laboratory in New York believe they have discovered a solution. They were able to make data that can fit expectations for the bizarre changing act using the laboratory’s Relativistic Heavy Ion Collider (RHIC).
Zhangbu Xu, who is a physicist at Brookhaven Lab, says in a statement that in their paper, Wheeler and Breit already realized that Einstein’s equation is a nearly impossible thing to be done, given that lasers didn’t even exist back then. However, Wheeler and Breit proposed another alternative: accelerating heavy ions. Their alternative is what they are doing at RHIC.
How Does It Work?
Instead of directly accelerating photons, the researchers sped up two ions, positively charged atomic nuclei stripped of their electrons, in a large loop before sending them past each other in a near collision. Because ions are charged particles traveling at near-light speeds, they also take an electromagnetic field with them, which contains a bunch of not-quite-real ‘virtual’ photons “flying with [the ion] like a cloud,” according to Xu.
Virtual particles are particles that exist only for a brief moment as perturbations in the fields between genuine particles. They aren’t as populous as their real-life equivalents (unlike their real counterparts that have no mass, virtual photons do have a mass). When the ions whizzed past each other in a close call in this experiment, their two clouds of virtual photons functioned as if they were real. When the real-acting virtual particles collided, they created a very real electron-positron pair, which the scientists were able to detect.
The physicists had to make sure that their virtual photons behaved like actual ones to be a valid observation of the Breit-Wheeler process, or as true as feasible using virtual particles. The physicists observed and examined the angles between more than 6,000 electron-positron pairs produced by their experiment to check the behavior of the virtual photons.
When two real particles collide, the secondary products should emerge at different angles than if two simulated particles collided. However, the simulated particles’ secondary products bounced off at the same angles as real particle secondary products in this experiment. As a result, the researchers were able to confirm that the particles they were observing behaved as if they had been created by a real encounter. The Breit-Wheeler process had been successfully demonstrated.
Albert Einstein’s Huge Contribution to Science
The energy and mass distribution of the systems were also measured by the researchers. In a statement, Brookhaven physicist Daniel Brandenburg said, “They are compatible with theory calculations for what would happen with real photons.”
Nonetheless, the virtual photons utilized in the experiment related to Einstein’s equation are indisputably virtual, even if they appear to behave like actual particles. This raises the question of whether the experiment truly demonstrated the Breit-Wheeler process, but it’s still a crucial first step until scientists build lasers powerful enough to demonstrate the process with real photons.
