O.o!!!! Woah even the news is talking about Dyson spheres now o.o

By Jacopo Prisco, CNN

(CNN) — What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept.

Karleigh Fry pioneers robotic neurosurgery:

An 8-year-old girl from Oklahoma has become the world’s first pediatric patient to undergo robotic deep brain stimulation (DBS).

The announcement was made by two collaborating hospitals, Oklahoma Children’s Hospital OU Health and Bethany Children’s Health Center.

It’s still just a plan, but a new telescope could soon be measuring gravitational waves. Gravitational waves are something like the sound waves of the universe. They are created, for example, when black holes or neutron stars collide.

The future gravitational wave detector, the Einstein Telescope, will use the latest laser technology to better understand these waves and, thus, our universe. One possible location for the construction of this is the border triangle of Germany, Belgium and the Netherlands.

Black holes and neutron stars are among the densest known objects in the universe. Within and around these extreme astrophysical environments exist plasmas, the fourth fundamental state of matter alongside solids, liquids, and gases. Specifically, the plasmas at these extreme conditions are known as relativistic electron-positron pair plasmas because they comprise a collection of electrons and positrons—all flying around at nearly the speed of light.

While such plasmas are ubiquitous in deep space conditions, producing them in a laboratory setting has proved challenging.

Now, for the first time, an international team of scientists, including researchers from the University of Rochester’s Laboratory for Laser Energetics (LLE), has experimentally generated high-density relativistic electron-positron pair– beams by producing two to three orders of magnitude more pairs than previously reported. The team’s findings appear in Nature Communications.

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.

Read about NASA’s latest demonstration for its laser communication system!

NASA astronauts Randy Bresnik, Christina Koch, and Kjell Lindgren, and other NASA employees recently sent images and videos of their pets to the International Space Station (ISS) via the agency’s Space Communications and Navigation (SCaN) program to further test laser communications between ground-based stations and space-based systems, including the ISS. This demonstration holds the potential to further enhance laser communications systems that could be useful for long-term space missions.

For this demonstration, the SCaN program used its elaborate and coordinated system consisting of the High-Rate Delay Tolerant Networking (HDTN), which is run by NASA’s Glenn Research Center and capable of sending data at quadruple the speeds of current DTN technology; NASA’s Laser Communications Relay Demonstration (LCRD), which orbits at 22,000 miles above the Earth; and the Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) payload attached to the ISS.

Four Russian warships including a nuclear submarine have reached Cuba, just 200 miles off the coast of Florida, ahead of a planned military exercise in the Atlantic. The fleet — made up of a frigate, a nuclear-powered submarine, an oil tanker and a rescue tug — arrived in Havana Bay on Wednesday, welcomed by a 21-cannon salute from Cuba. Dramatic images from the arrival show the ominous and massive vessels entering the bay as Cubans lined up on…

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.
