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.

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.
“For those that know rockets, this is a ridiculously hard thing.”
As this is the first Falcon 9 rocket to launch nine missions, it raises the prospect of a first stage making a tenth flight in the near future, probably within a month or two. Reaching ten flights would accomplish one of the main goals set by SpaceX with the Falcon 9 rocket, after optimizing the vehicle for reuse about three years ago.
The company debuted its “Block 5” version of the Falcon 9 rocket in May 2018, and since then this vehicle has flown 55 missions, all of which have successfully delivered their payloads to orbit. More importantly, the changes SpaceX engineers incorporated into this new rocket to ensure its robustness for reuse, such as strengthening its “Octaweb” engine bay, have largely been validated.
“For those that know rockets, this is a ridiculously hard thing,” SpaceX founder Elon Musk said during a teleconference with reporters in 2018 to discuss the Block 5 upgrades. “It has taken us since, man, since 2002. Sixteen years of extreme effort and many, many iterations, and thousands of small but important development changes to get to where we think this is even possible.” He paused for a second, and then added, “Crazy hard.”
Starship SN11 will re-attempt a Static Fire test Tuesday – following a scrub on Monday – ahead of a potential flight later this week. Forever subject to change due to numerous considerations – ranging from weather, hardware parameters, and paperwork approval – SN11 will mark the final test of this iteration of Starship before the program moves into the next phase of testing.
Following SN11’s flight, SpaceX will move on to SN15, 16, and 17, alongside testing with Super Heavy prototypes BN1 and BN2, before shooting for an orbital launch with SN20 and BN3. In typical SpaceX-style, that orbital launch has an astonishing – and unlikely – “by July 1” target. At the very least, this target portrays SpaceX’s Starship drive to push the vehicle into operation. SN11:

SpaceX sent Starman into space on a Falcon Heavy 3 years ago! But will he ever return to Earth?
Fascinating new episode with NASA astrophysicist Sten Odenwald; we discuss several of his 100 objects in his book on the history of space exploration. Please listen.
Award-winning NASA astrophysicist and author Sten Odenwald discusses several of the 100 objects featured in his 2019 book: “Space Exploration: A History in 100 Objects.” I pick a few of the lesser known and underappreciated objects, which run the gamut in their differing ages. In this compelling episode, it’s amazing to hear and understand just how far humanity has come in its technological quest to understand the cosmos.
