Title: What Is Space Density? From Medium Ontology to the Spacetime Constant K Date: March 8 2026 10:00 am - Noon EDT Abstract: Spacetime plays an active role in gravity, wave propagation, and quantum behavior, yet physics rarely treats it as a physical medium with intrinsic properties such as density or inertia. This missing layer creates a major conceptual gap—especially when interpreting large-scale gravitational anomalies that are often attributed to dark matter. In this talk, Lynn will propose a clear conceptual framework for what it means for spacetime itself to possess a density-like property, and Lynn will explain why Unified Field Theory (UFT) naturally encodes this property through the constant K, called the spacetime background inertial intensity constant. Lynn will introduce a space-density constant μₛ as a universal property of space itself—independent of matter, energy density, or gravitational sourcing. However, μₛ cannot be inserted directly into field equations, because it belongs to the ontological level: it describes what space is, not how spacetime responds. To influence dynamics, μₛ must be expressed geometrically. This leads naturally to K, which carries the same physical meaning but operates at the level required by geometric field dynamics. This is a change in representation—not the addition of new physics. This approach provides an alternative way to interpret dark-matter-like effects. Instead of requiring unseen particles, gravitational anomalies can be viewed as consequences of spacetime’s intrinsic rigidity and its global, cumulative response in large coherent systems such as disk galaxies. In local, weak-field environments, standard Newtonian and relativistic gravity remains an effective approximation. The goal of the talk is not to present a final empirical model, but to clarify the physical meaning of spacetime constants and open discussion between UFT and mainstream theoretical physics. Keywords: Spacetime ontology; space density; intrinsic spacetime properties; Unified Field Theory (UFT); spacetime background constant K; geometric response; gravitational coupling; dark-matter-like phenomena Brief Biography Lynn Lou Beran is a Senior IT Security Analyst and an author, translator, and editor working at the intersection of science, engineering, and communication. She translated and edited multiple editions of Zhang XiangQian’s Unified Field Theory and co-authored recent manuscripts developing a geometric, motion-based view of physical reality. Lynn’s broader work focuses on making advanced ideas accessible without sacrificing rigor, and on connecting conceptual insight to testable predictions and practical tools.

To help us estimate attendance and to see the venue address, please RSVP on Luma!: https://luma.com/af0yjzz6 *A free, public workshop—no technical background needed* ​Artificial intelligence is no longer just getting better at narrow tasks—it’s beginning to look *general*. Many researchers believe we’re entering the early stages of the **AGI transition**: a period where AI systems start to match or exceed human abilities across a wide range of domains. ​This workshop explores what AGI actually means, how to think about it intuitively (without hype or jargon), and what this transition could mean for your job, your relationships, and your day-to-day life—much sooner than most people expect. ​Together, we’ll explore questions like: ​**What is AGI?** ​How do experts define artificial general intelligence, and how is it different from today’s AI tools? ​**Work & Jobs:** ​Which kinds of jobs are already being automated or transformed—and which ones experts believe are most likely to remain resilient? ​**Human Connection:** ​How is AI starting to replace or supplement roles once filled by coworkers, friends, tutors, therapists, and companions? ​**Robots & the Physical World:** ​What happens when advanced AI is paired with rapidly improving robotics—and which parts of the economy could change next? ​**What you’ll get:** * ​A clear, beginner-friendly explanation of AGI and why it matters * ​Real-world examples of how AI is already reshaping work and social life * ​Live demos that highlight both impressive capabilities and emerging risks * ​Interactive discussion and exercises to test your own intuitions about the future ​Come ready to grapple with one of the biggest transitions humanity may ever face—a shift that could redefine not just how we work, but how we relate to each other, find meaning, and navigate a world increasingly shaped by intelligent machines.

Winter’s on the wane and signs of spring are popping up, making now a perfect time to appreciate the intermingling of the best of both seasons. Experience the beauty of bare tree architecture and the welcome sight of early bloomers on a stroll abounding with sensory delight at Green Spring Gardens, a local treasure. Tuning in with our senses, we’ll combine slow strolling with attentive pauses to deepen our connection with nature. Green Spring offers space for quiet enjoyment throughout the seasons, and is particularly noted for its collection of dozens of cultivated varieties of witch hazels of many colors. Their unusual flowers are among the earliest to open, often blooming amidst snow and ice, and they are in bloom now. There’s pussy willow (pictured) too. The health benefits of slowing down in quiet company among trees and plants with senses alert and aware are scientifically documented, but the best way to understand these benefits is to experience them yourself, preferably on a regular basis. IMPORTANT! The size of the group is limited! Please be sure to update your status asap on either the “going” or “wait list” if you sign up and find you can’t make it! Walking under 2 miles is mostly on natural, somewhat uneven surfaces, with a few short hills. Wear good walking shoes, a hat and sunscreen, and bring water (or tea) to drink. Park and meet near the open gate on Witch Hazel Rd at Green Spring Gardens 38.82428° N, 77.15808° W 4500-4504 Witch Hazel Rd, Alexandria, VA Please arrive by 8:45 to sign the required SCPRO waiver.

Saturday is forecast to be 78 degrees and sunny. We did this hike last month but skipped the park because the trail was covered by ice & snow. No such problem this time. We will meet at noon by the Tenleytown metro station and walk down Nebraska to Foxhall Road and back up the Glover Archbold Trail. We will stop at the National Cathedral and then wend our way back to Tenleytown. The starting point for the hike is a hop and a skip from a Whole Foods store with the best peanut butter cookies in the D.C. area. ❶ **What we'll do:** * From the meetup point we'll walk southeast along Wisconsin Ave NW, turn left at Nebraska Ave NW and follow it southwest to Foxhall Rd NW, * We will hook a left on Garfield Ave. and follow to the Glover-Archbold Trail through the woods back to Cathedral Ave. We will cross Wisconsin Ave and stop at the National Cathedral. We will then wend back to Tenleytown via 36th St., 37th St., and Van Ness. * Total distance is around 5 miles and should take about 2 hours, . The surface is paved and slightly downhill on the way out, and a slightly uphill mix of pavement and woodland trails on the way back. This is a fairly easy walk. * [map is for prior version of the hike; update pending] Google map: http://tinyurl.com/y9bthc7a ❷ **How to get there:** * Metro (recommended): The Tenleytown - AU Metro Station is on the Red Line. See the Metro Trip Planner at https://www.wmata.com/ * Driving: If you must drive, the Tenleytown - AU Metro Stationstreet address is 4501 Wisconsin Ave NW, Washington, DC 20016. There is limited parallel parking in the area, but mind the street signs and leave plenty of time to find a spot! ❸ **What to bring:** Plenty of water, comfy shoes. ❹ **Weather:** The forecast is sunny and a high temperature of 78F. Updates here: https://tinyurl.com/sw2ejvu8 ❺ **Advisory**: As a reminder, this is an adult group, and you are ultimately responsible for your own safety and well-being during events. No one under 18 years of age is allowed at this event, either as members or as guests, to include babies in carriers and/or strollers.

Meeting Room 2b, Main Library Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. We desirere to cultivate a space where all questions are welcome and all members are treated with compassion and respect. All backgrounds are welcome.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.

Always an overachiever, David Bayer didn't settle for being Number Two in just about anything. Whether a runaway entrepreneurial success as a teenager, the leading online director for Ducati with over $70 million in sales, or as an early mid-life crisis overachiever with at least three wildly self-destructive behavioral addictions, whatever David did, he did it wholeheartedly. Not surprisingly then, when it came to facing his failures and determining his next course of action, David sought health and healing with the same full-strength effort he had previously used to bring about his own ruination. Seeking to learn from the best of the best, David's pursuit of tangible, practical, actual change from the mind and emotions, outward, brought a new passion--that of encouraging others to learn from his mistakes and to be able to strive after and achieve healing and success in their own lives. We are reading *A Changed Mind*, by David Bayer, and can't wait to enjoy the group discussion on **Wednesday, March 4, 2026, 6:30 pm**, at **True Food Kitchen, Easton Town Center**. Come join us!

Wouldn’t it be nice to find a way to overcome your feelings of anger so that you not only control them, but you no longer have the urge to lose your temper in the first place? And how about being able to shake off resentments, persistent annoyance, or even feelings of vengeance? We’d like to invite you to an event on how to overcome anger and resentment. We will show you why people have trouble controlling their temper and where resentment comes from. Flaring anger can ruin a meeting, a relationship, an opportunity, or just about any aspect of life. Worst of all, outbursts towards our family can create hurt that lingers throughout a lifetime. You want to have a civil conversation, and you’ve vowed that you wouldn’t lose your temper, but a few minutes later, the anger flares up. Maybe you’ve realized that being angry doesn’t get you what you want so you internalize it. Or maybe you avoid the knockdown, drag-out fights, but stewing in resentment is exhausting and takes an emotional toll. In this event we show you how to get to the root of your anger so that it stops being an issue to you. You’ll also learn why people harbor resentments and how to move on. Don't continue to struggle, make a difference in your life, and join us for this local event. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This Meetup is sponsored by your local Dianetics and Scientology Life Improvement Center.

Sleep in on Sundays. When you've had your fill of pajama-time, roll out and have some tasty brunch with your fellow Humanists!
