An alternative theory to all the theories currently in use. This is what the world needs now. The Fundamental Speed Theory (FST): A Unified Vector Field Framework for Dark Matter, Baryogenesis, and Gravitational Lensing

To all who carry a passion for science,To those who believe that knowledge belongs not to geography, but to the mind— My name is Raheb Ali Mohammed Saleh Aoudh. I am a 30-year-old independent researcher from Yemen, living in a rural region of Bani Al-Harith District, Sana'a. I have no access to laboratories, universities, research teams, or even stable electricity. I do not own a computer. I have never worked with a professor or a student. All I have is a basic mobile phone, a weak internet connection, and a mind that refuses to stop asking questions. Despite these limitations, I developed a new cosmological theory from scratch, based on a custom Lagrangian. I call it the Fundamental Speed Theory (FST). This theory does not rely on dark matter or dark energy. Instead, it reinterprets cosmic expansion, the cosmic microwave background (CMB), and the dynamic equation of state—all from the behavior of a single vector field \( V_\mu \). I implemented numerical simulations using open-source tools, integrated the results into CAMB, and compared them with Planck data and SPARC galaxy rotation curves. The results were striking, and they demonstrate that FST is not only viable—it may outperform the standard ΛCDM model in several key areas. --- 💎 Strengths Proven by the FST Model 1. No need for dark energy FST naturally produces cosmic acceleration from the vector field \( V(t) \), with the equation of state reaching \( w = -1 \) without invoking a cosmological constant. 2. No need for dark matter The model reproduces the CMB spectrum and galaxy rotation curves without cold dark matter (CDM), showing that the vector field dynamically replaces its gravitational effects. 3. Third CMB peak alignment The third acoustic peak matches Planck data with only 0.75% deviation, confirming the model’s precision in simulating photon-baryon plasma physics. 4. Numerical consistency with observations - Universe age: 13.63 billion years - Hubble constant: 71.77 km/s/Mpc - Final equation of state: \( w = -1.0000 \) These values fall within modern observational ranges and help resolve tensions between Planck and SH0ES. 5. SPARC galaxy data compatibility FST accurately reproduces galaxy rotation curves without dark matter, showing that the vector field generates nonlinear gravitational effects at galactic scales. 6. Equations derived from a custom Lagrangian All field equations are derived from the principle of least action, with no arbitrary modifications to Einstein’s equations—giving FST full theoretical independence. 7. Stable numerical solutions The model was tested using multiple solvers (BDF, RK45, etc.), and results remained stable across a wide range of initial conditions. 8. Scalability to structure formation The vector field promotes baryonic clustering and can be extended to include perturbations and large-scale structure formation—without CDM. --- Why I’m writing this To say that science is not born only in Harvard or Cambridge—it is born wherever a mind dares to dream. To invite the scientific community to evaluate the theory, not the background of its author. To ask that ideas be judged by their merit, not by their origin. To prove that physics belongs not to institutions, but to humanity. --- What I ask of you - Read the theory with scientific eyes, not social filters - Discuss it, test it, challenge it - Show that the scientific community embraces ideas, regardless of where they come from --- And finally… I do not seek personal recognition. I seek recognition that free thought can rebuild our understanding of the universe—even from the rocky hills of Yemen. Attached are the full manuscript, numerical code, and cosmological results. I welcome all correspondence, collaboration, and critique. With respect, RAHEB ALI MOHAMMED SALEH AOUDH 📧 [email protected] For your information, I did all of this in just 25 days. A month ago, I wasn't thinking about this theory and I didn't care about physics at all. I don't know what happened. I just found myself proficient overnight. Let's be transparent.
