The Physics of FTL Travel

Can humanity ever travel faster than light, or does every shortcut through spacetime break causality itself? We explore warp drives, wormholes, tachyons, and why the universe pushes back.

Joscha Bach: “Consciousness is a Second Order Perception”

What if consciousness is just perception perceiving itself? Is that proof we’re in a simulation? Come geek out inside The Giant’s Shoulder → https://www.skool.com/the-giants-shou…

You’re not just perceiving the world — you’re perceiving that you perceive, and Joscha Bach says that loop is what consciousness actually is. The AI researcher and cognitive scientist unpacks consciousness as second-order perception: not raw data like a self-driving car has, but a model of the modeller that keeps the observer stable inside a self-organizing brain. From there it gets stranger — Bach argues the reality you experience is a real-time simulation your brain renders, running at the speed your neurons fire. He explains why subjective experience tops out around 20–50Hz, why that points to consciousness being brain-produced rather than fundamental, and why the self you think you are is a disembodied pattern using a body to reproduce itself.

Space Renaissance International at COPUOS 69, Vienna, 10

(SRI) was represented at the 69th Session of the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) in Vienna, Austria, by Bernard Foing, Dr. Gülin Dede, Werner Grandl, and Enes Beşli. The SRI delegation contributed to the session’s dialogue through two technical presentations: one delivered by Werner Grandl, “The Legacy of Gerard K. O’Neill and the Urgency to Start Experimentation on Simulated Gravity,” and another by Dr. Gülin Dede titled “Sustainability Beyond Earth: The Case for an 18th Sustainable Development Goal.” Throughout the session, the delegation engaged in productive discussions with international stakeholders and explored potential avenues for collaboration in support of SRI’s vision for a sustainable and inclusive space future. The delegation also attended the side event “Delivering Water Diplomacy through Space,” jointly co-organised by the European Space Policy Institute and Slovenia.

SRI further observed the “Space4Industry, UNOOSA/UNIDO Signing Ceremony,” co-organised by UNOOSA and UNIDO, as well as the “Space4Resilience Initiative, From Data to Decision: AI-Driven 3D Digital Twin Technologies for Disaster Infrastructure Resilience and Sustainable Industrial Development,” co-organized by UN-SPIDER and Japan.

SRI supports the utilization of space technologies in addressing global challenges, advancing sustainable industry, and strengthening international cooperation.

T cell control of the intestinal barrier and gut microbiota during ageing

The epithelial, microbial, and immune components of the intestinal barrier coexist in harmony to prevent undesirable inflammatory outcomes and ensure homeostasis in the host. In this review, we outline molecular mechanisms by which T cells regulate intestinal homeostasis and how the ageing-associated dysfunction of T cells could disturb host–microbiota symbiosis and the physical integrity of the intestinal barrier, ultimately driving inflammageing and poor health outcomes. Finally, we propose microbiota- and T cell-based therapeutic interventions aimed at strengthening the intestinal barrier to promote healthier longevity. Namely, we discuss the transplantation of youthful microbiota, the use of designed probiotics, and the adoptive transfer of competent or engineered T cells.

AI Development Highlights To Watch-Out For In 2025 & Beyond

~ AI supremacy & digital empires.

There is something critical taking place in the world now.

It has something to do with the neurological response system of humans.

Basically, when something happens, our sensory/nervous system processes it and guides us in the best way to respond.

That system is being blunted to death in everyone living in today’s world.

We have become so stimulated by numerous technological, socioeconomic and geopolitical shocks, that, we are almost in a helpless trance-like state now (the usual rounds of life).

We can only just watch as the world unfolds into a dystopian singularity before our eyes— wars & conflicts, natural disasters, alien disclosures, unending AI updates now laced with political & economic tensions, World Cup & UFC fevers, Stock Market volatility etc… etc…
