A massive rocket booster for a massive Starship.
SpaceX CEO Elon Musk showed off the company’s first Starship Super Heavy booster in a Twitter post on Thursday (March 18).
Venus: how Rocket Lab could reveal the under-explored planet’s secrets.
Rocket Lab is building its largest rocket ever, and its CEO has big plans to get to Venus.
“We’re going to try to catch the Super Heavy booster with the launch tower arm, using the grid fins to take the load,” Musk said via Twitter on Dec. 30. SpaceX will try a different approach to landing its future reusable rocket boosters. There are some benefits with this landing method: first, by omitting landing legs from the rocket design altogether, SpaceX can save weight and cost, because unlike Falcon 9 and Falcon Heavy first stages Super Heavy won’t need landing legs. In a second place, it could allow SpaceX to essentially recycle the Super Heavy booster immediately because the rocket would be “ready to refly in under an hour”.

Do humans really have to go into space?
Artificial intelligence has been making waves in recent years, enabling us to solve problems faster than traditional computing could ever allow. Recently, for example, Google’s artificial intelligence subsidiary DeepMind developed AlphaFold2, a program which solved the protein-folding problem. This is a problem which has had baffled scientists for 50 years.

A fundamental decision on a new station would be made by the end of this year, he said.
Rogozin said that current negotiations with NASA on the future of the ISS were “shallow”. He speculated that ISS’s life cycle would be repeatedly prolonged not by several years, but by one year. Also, he said it might be possible to extend the service life not of the whole station, but of its individual modules.
“On the sidelines of the April 9 launch we plan to hold technical consultations with NASA,” Rogozin said, adding there was a possibility of configuring the Lunar orbital platform Gateway for its possible docking with Russia’s new generation spacecraft Oryol.
Today on the Science Talk podcast, Noam Slonim speaks to Scientific American about an impressive feat of computer engineering: an AI-powered autonomous system that can engage in complex debate with humans over issues ranging from subsidizing preschool and the merit of space exploration to the pros and cons of genetic engineering.
In a new Nature paper, Slonim and colleagues show that across 80 debate topics, Project Debater’s computational argument technology has performed very decently—with a human audience being the judge of that. “However, it is still somewhat inferior on average to the results obtained by expert human debaters,” says Slonim.

A theoretical way to create a sub-light warp drive has been described that does not require negative mass. This could enable fast travel through our Solar System and onwards to distant star systems.
A unique — details are a bit sketch 😉 looks amazing tho!

Graph representations can solve complex problems in natural science, as patterns of connectivity can give rise to a magnitude of emergent phenomena. Graph-based approaches are specifically important during quantum communication, alongside quantum search algorithms in highly branched quantum networks. In a new report now published on Science Advances, Max Ehrhardt and a team of scientists in physics, experimental physics and quantum science in Germany introduced a hitherto unidentified paradigm to directly realize excitation dynamics associated with three-dimensional networks. To accomplish this, they explored the hybrid action of space and polarization degrees of freedom of photon pairs inside complex waveguide circuits. The team experimentally explored multiparticle quantum walks on complex and highly connected graphs as testbeds to pave the way to explore the potential applications of fermionic dynamics in integrated photonics.
Complex networks
Complex networks can occur across diverse fields of science, ranging from biological signaling pathways and biochemical molecules to exhibit efficient energy transport to neuromorphic circuits across to social interactions across the internet. Such structures are typically modeled using graphs whose complexity relies on the number of nodes and linkage patterns between them. The physical representation of a graph is limited by their requirement for arrangement in three-dimensional (3D) space. The human brain is a marked example of scaling behavior that is unfavorable for physical simulation due to its staggering number of 80 billion neurons, dwarfed by 100 trillion synapses that allow the flow of signals between them. Despite the number of comparably miniscule volume of nodes, discrete quantum systems faced a number of challenges owing to complex network topologies, efficient multipartite quantum communications and search algorithms.
In my last post, I talked about the idea of warp drive and whether it might one day be possible. Today I’ll talk about another faster-than-light trick: wormholes.
Wormholes are an old idea in general relativity. It’s based on work by Albert Einstein and Nathan Rosen, who tried to figure out how elementary particles might behave in curved spacetime. Their idea treated particle-antiparticle pairs as two ends of a spacetime tube.
This Einstein-Rosen Bridge would look like a black hole on one end, and an anti-black hole, or white hole, on the other end.
