Ugly.

Job losses are always terrible. This will be a dark and painful day at a space agency that brings so much light and joy to the world. Many of the probationary employees are just starting out their careers and were likely thrilled to land a job at NASA to explore the universe. And then all of that youthful energy and hope was extinguished this week.

It’s possible to view these losses through a couple of lenses.

Yes, NASA is clearly losing some capability with these latest cuts. Many of these hires were likely being counted on to bring new energy into the space agency and become its future discoverers and leaders. And their jobs are being sacrificed for no clear purpose. Is it to increase funding for the military? Is it to pay for tax cuts for the rich? There is a lot of anger that the relatively thin budget line of NASA—less than one-half of 1 percent of the federal budget—is being sliced for such purposes.

Will the dream of interstellar travel soon become reality? Experts have been working for some time on concepts that will one day enable us to enter foreign star systems. Until now, the vast expanses of space have always thwarted this ambitious desire – after all, even the Alpha Centauri system, which is only 4.34 light-years away, is tens of thousands of travel years away with our current means! But now NASA has presented a revolutionary propulsion technology that should get us to the star system of our dreams in just 40 years! But how does the groundbreaking Sunbeam drive work? What technical tricks will make the vast distances of the cosmos seem forgotten – and when will the first interstellar research probe leave Earth?

Earth is 4.5 billion years old… modern humans are only 300,000 years old. The history of our species on this planet is incredible, but there are theories that humankind is actually much more spread out across the universe!

“Just like tuning forks of different material will have different pure tones, remnants described by different equations of state will ring down at different frequencies,” Rezzolla said in a statement. “The detection of this signal thus has the potential to reveal what neutron stars are made of.”

Gravitational waves were first suggested by Albert Einstein in this 1915 theory of gravity, known as general relativity.

Astronomer Calvin Leung was excited last summer to crunch data from a newly commissioned radio telescope to precisely pinpoint the origin of repeated bursts of intense radio waves—so-called fast radio bursts (FRBs)—emanating from somewhere in the northern constellation Ursa Minor.

Leung, a Miller Postdoctoral Fellowship recipient at the University of California, Berkeley, hopes eventually to understand the origins of these mysterious bursts and use them as probes to trace the large-scale structure of the universe, a key to its origin and evolution. He had written most of the computer code that allowed him and his colleagues to combine data from several telescopes to triangulate the position of a burst to within a hair’s width at arm’s length.

The excitement turned to perplexity when his collaborators on the Canadian Hydrogen Intensity Mapping Experiment (CHIME) turned optical telescopes on the spot and discovered that the source was in the distant outskirts of a long-dead elliptical galaxy that by all rights should not contain the kind of star thought to produce these bursts.

Based on outstanding technical progress by research teams to date, DARPA has pivoted the third and final phase of its NOM4D (pronounced nō- mad) program[1] from planned further laboratory testing to conducting a pair of small-scale orbital demonstrations to evaluate novel materials and assembly processes in space.

As commercial space companies continue to expand access to orbit for U.S. economic and national security needs, a major roadblock for building large-scale structures in orbit remains: the size and weight limits imposed by a rocket’s cargo fairing. In 2022, DARPA introduced NOM4D to break this cargo-constraint mold by exploring a new paradigm. Instead of folding or compacting structures to fit them into a rocket fairing to be unfurled or deployed in space, DARPA proposed stowing novel lightweight raw materials in the rocket fairing that don’t need to be hardened for launch. The intent of this approach is to allow in-orbit construction of vastly larger and more mass-efficient structures than could ever fit in a rocket fairing. Additionally, this concept enables mass-efficient designs of structures that would sag under their own weight on Earth but are optimized for the low-gravity environment of space.

“Caltech [California Institute of Technology] and the University of Illinois Urbana-Champaign have demonstrated tremendous advances in the first two phases and have now partnered in Phase 3 with space-launch companies to conduct in-space testing of their novel assembly processes and materials,” said Andrew Detor, DARPA NOM4D program manager. “Originally, Phase 3 was going to be about making things more precisely in the lab than we did in Phase 2. But we said, ‘You know, the maturity is there, and there would be more impact if we took the capabilities we have now and actually go demonstrate them in space to show that it can be done.’ Pushing the performers to do a demo in space means they can’t just sweep challenges under the rug like they could in a lab. You better figure out how it’s going to survive in the space environment.”

I love his hypergraph theory.

Hypergraphs can have any number of dimensions. They can be 2-dimensional, 3-dimensional, 4.81-dimensional or, in the limit, ∞-dimensional.

So how does the three-dimensional space we observe emerge from the hypergraph-based Wolfram model?

Hypersonic jet that can travel between london and new york in one hour set for test flight.

In a groundbreaking development for the aviation industry, Venus Aerospace, a Texas-based company, is preparing to conduct the first test flight of a hypersonic jet that promises to reduce the flight time between London and New York to just one hour. The hypersonic jet, dubbed the Stargazer, is designed to travel at speeds up to Mach 6, which is six times the speed of sound, and represents a major leap forward in air travel technology.

The journey from New York to London typically takes around seven hours on a conventional passenger aircraft. Even Concorde, the legendary supersonic aircraft, managed the route in just under three hours. However, with the introduction of the hypersonic Stargazer, that travel time could be slashed to a mere 60 minutes.
