⏰️ T I M E 🐇 Drifting off to sleep last night these words came into my mind (i.e. words from elsewhere): 1. "Time is not linear." 2. "Time is longer than you think." The first is not surprising, why would time be linear? Makes more sense that time is periodic, circular (those Fast Fourier Transform graphs spring to mind), but at what scale - all? And does it mean the universe is cyclical at the largest scale? The second is interesting. Does it mean that the universe is older than we think? i.e. That time emerged earlier than we think. Does it mean that the speed of light is not constant over cosmogenesis? i.e. that estimates of the duration of all Time, as measured by light, are an underestimate.

A bold new theory says the universe may exist because of knots. Japanese physicists just dropped a mind-bending idea that might finally solve one of cosmology’s biggest mysteries: why there’s something instead of nothing. Right after the Big Bang, the laws of physics say matter and antimatter should have been created in perfect 50–50 balance. When they touch → total annihilation. Poof. Universe over before it started. Yet here we are. The only reason anything exists is that, for every billion antimatter particles, there was one extra matter particle left over. That microscopic surplus built every star, planet, and person. A new theory from a team in Japan says the answer lies in “cosmic knots”: ultra-stable, topologically twisted loops of pure energy that formed in the infant universe. By uniting two deep symmetries in particle physics — B–L (baryon-minus-lepton number) and the Peccei–Quinn symmetry tied to axions — they show these knots naturally emerge, dominate the energy budget for a fleeting moment, then quantum-tunnel apart. When the knots finally unravel, they spit out massive right-handed neutrinos that decay asymmetrically, handing matter the decisive victory over antimatter. Baryogenesis, solved in one elegant stroke. Best part? The violent un-knotting should have blasted a unique pattern of gravitational waves across spacetime — a smoking-gun signal that future space detectors like LISA and DECIGO might actually hear. The universe, it turns out, may owe its very existence to a few primordial knots coming undone. Paper just out — physicists are already running simulations to test it.

🚨 RUSSIA JUST REVEALED A PLASMA ENGINE THAT COULD CHANGE SPACE TRAVEL FOREVER. And it’s fast enough to make current rockets look ancient. Rosatom’s new plasma propulsion prototype reportedly accelerates particles to 100 km/s with endurance tests lasting over 2,400 hours. That matters because conventional chemical rockets are incredibly inefficient for deep space. Most of the fuel is burned just escaping Earth. But plasma engines work differently: Instead of explosive combustion… they use electromagnetic fields to accelerate superheated charged particles at extreme velocities. In simple terms: They turn electricity into a continuous stream of ultra-fast plasma thrust. Why this matters: • Mars trips potentially cut to 30–60 days • far lower fuel mass • continuous acceleration in space • deep-space cargo missions • future interplanetary infrastructure But the deeper implication is bigger: The future of space travel may not belong to giant explosions… …but to controlled electromagnetic physics. Chemical rockets were the first chapter. Field propulsion may be the next. And once travel times collapse… the psychological distance between planets collapses too. Mars stops feeling like another world… and starts feeling like a destination. What happens when humanity can move through the Solar System almost as easily as crossing oceans?

@jaynitx I like it! Though he's not expanding consciousness imo, rather, the spatio-temporal range of human DNA.

Elon Musk reveals the single idea that explains why he keeps working despite being worth $800 billion "When I was a teenager, I had an existential crisis trying to figure out what's the meaning of life. It doesn't seem to be any meaning" "For me at least, the religious texts that I read did not seem convincing. Then I started reading the philosophers. You have to be careful of reading German philosophers as a teenager. It's definitely not going to help with your depression" "Reading Schopenhauer and Nietzsche, as a kid you're like, whoa" "Then I read Hitchhiker's Guide to the Galaxy. What Douglas Adams was saying is that we don't really know what the right questions are to ask. The real problem is trying to formulate the question. To really have the right question, you need a much bigger computer than Earth" "The universe is the answer. What is the question? Or what are the questions?" "The more we can expand the scope and scale of consciousness, the better we can understand what questions to ask about the answer that is the universe" "The more we can expand consciousness, become a multi-planet species, ultimately a multi-stellar species, we have a chance of figuring out what the hell's going on" "This is why I think we should have more humans and more digital, both biological and digital consciousness"

@its_The_Dr Airbags and sensible cars, very on topic today... 😉😂 #synchronicity

Going up? Yes in every positive possible way. @SpaceX

We have to remember that what we observe is not nature herself, but nature exposed to our method of questioning. -- W. Heisenberg (Physics and Philosophy, 1958)

@PhysInHistory As long as we keep that front of mind.

@MelAaronGibson1 Adorable. 🤩 My younger dog goes nuts if I 'dance' in the kitchen. Lol. Fortunately dogs are all fun and no judgement.

This dog 🐕❤️ This is Officer Brian Santos and his K9 partner Kyra from Cocoa PD in Florida. They’ve been a team since 2018. Impressive!

@DAVET800 @JohnCleese 😊

@JohnCleese ARF !!

I hope this doesn't cause anyone offence

I am optimistic that we will one day make contact to extraterrestrials because I don't think that the speed of light is a fundamental limit. Here I explain why and I have a brief summary below.

@Rainmaker1973 😊

Just a dog having the best day of its life.
