How many Dyson Spheres, a hypothetical energy source, could be built around stars in the Milky Way?
Researchers calculated the maximum amount of Dyson Spheres in the Milky Way in order to know what it is they did not find.
Researchers have created a device that enables them to electronically steer and focus a beam of terahertz electromagnetic energy with extreme precision. This opens the door to high-resolution, real-time imaging devices that are hundredths the size of other radar systems and more robust than other optical systems.
Terahertz waves, located on the electromagnetic spectrum between microwaves and infrared light, exist in a “no man’s land” where neither classic electronics nor optical devices can effectively manipulate their energy. But these high-frequency radio waves have many unique properties, like the ability to pass through certain solid materials without the health effects of X-rays. They may also enable higher-speed communications, or vision systems that can see through foggy or dusty environments.
The Terahertz Integrated Electronics Group at MIT, led by Associate Professor Ruonan Han, seeks to bridge this so-called terahertz gap. These researchers have now demonstrated the most precise, electronically steerable, terahertz antenna array, which contains the largest number of antennas. The antenna array, called a “reflectarray,” operates like a controllable mirror with its direction of reflection guided by a computer.

The photos look like a scene out of science fiction: Robot dogs patrolling the US-Mexico border, climbing over harsh terrain to search for threats and contraband.
But these images are real.

For centuries, people have dreamed of being driven at speed across the vast oceans of space by winds of light.
As whimsical as the idea sounds, nudging reflective sails slowly towards the speed of light using nothing more than the punch of photons might be our only plausible shot at reaching another star inside of a single human lifetime.
It’s also far easier said than done. Particles of light might be fast, but they don’t push very hard. If you make a sail light enough to feel the inertia of radiation, then the constant barrage of photons could inadvertently damage its material.
The Google-backed AI firm taught a reinforcement learning algorithm to control the fiery plasma inside a tokamak nuclear fusion reactor.
Study of the evolution of monotheism is instructive. Jolly Jehovah did not burst forth fully formed overnight. Prof Orly Goldwasser explains how Amen and Ra are “better” Gods than Set of Avaris, the first recorded monotheist deity in her 2006 paper on King Apophis. There is evidence of interchangeable identity between Set and Ba’al Hadad. “According to the Canaanite pantheon, known in Ugarit as ‘ilhm (=Elohim) or the children of El (cf. the Biblical “sons of God”), supposedly obtained by Philo of Byblos from Sanchuniathon of Berythus (Beirut) the creator was known as Elion (Biblical El Elyon = God most High), who was the father of the divinities, and in the Greek sources he was married to Beruth (Beirut = the city). This marriage of the divinity with the city would seem to have Biblical parallels too with the stories of the link between Melkart and Tyre; Yahweh and Jerusalem; Chemosh and Moab; Tanit and Baal Hammon in Carthage. El Elyon is mentioned as ‘God Most High’ occurs in Genesis 14.18−19 as the God whose priest was Melchizedek king of Salem.”
Canaanite religion is the name for the group of Ancient Semitic religions practiced by the Canaanites living in the ancient Levant from at least the early Bronze Age through the first centuries of the Common Era. Canaanite religion was polytheistic or monolatristic, worshiping one god while acknowledging the existence of others. The sources for Canaanite religion come either from literary sources written by the early Hebrews, or from archaeological discoveries. The Canaanite wrote on papyrus and.
In a way, it could mean climate change is linked to an “immature technosphere”.
It’s called an epiphenomenon.

But thankfully it did NOT involve 6 malevolent AI robot arms, NOR was it done in the middle of New York City by an oddly literally named Doctor Octavious. ☝️😉
Google’s DeepMind can dynamically adjust the magnetic fields inside a tokamak.
Elon Musk’s The Boring Company has submitted a proposal to construct a 6.2-mile underground transit system in Miami, Insider can reveal.
The North Miami Beach Loop would ferry Tesla vehicles between seven stations along State Road 826, between the Golden Glades Transit Center and Sunny Isles Beach at Newport Pier, according to the proposal, seen by Insider.
The Boring Company estimated that the loop would initially be able to carry more than 7,500 passengers per hour, and could be scaled to carry more than 15,000 per hour.
