Dark matter actually exist? Physics research by Naman Kumar suggests that modified gravityrather than invisible particlesexplains galactic rotationpotentially removing the need for mysterious mass in cosmic models.
Physicists traditionally argue that invisible mass outweighs baryonic matter five to oneexplaining why galaxies hold together despite rapid rotation. Howevernew findings suggest gravity’s strength might change over galactic distances.
Naman Kumar proposes an infrared running scheme where gravity deviates from the standard inverse square law. This theoretical shift could account for observations previously attributed to unseen halos of dark particles.
Discovering if dark matter actually exist
Evidence suggests dark matter actually exist primarily to explain galactic rotation and gravitational lensing. Howevernew quantum field theory research proposes that gravity’s variable strength on large scales could replace these invisible particles entirely.
The question of whether dark matter actually exist arises from galactic rotation curves where stars move faster than expected. Kumar’s infrared running scheme suggests gravity behaves differently over vast distancespotentially eliminating the need for cold dark matter while remaining consistent with early-universe precision measurements and cosmic microwave background.
Physicists investigate if dark matter actually exist because visible matter alone cannot generate enough gravity to hold galaxies together. This new theoretical model proposes that the gravitational constant “runs” or changesproviding the necessary force without extra particles.
The Infrared Running Gravity Model
New theoretical research explores whether dark matter actually exist by applying quantum field theory to gravity at galactic scales. Instead of a fixed valuethe gravitational constant might shiftcreating a long-range force that accounts for rapid galactic spins without invoking invisible mass components or mysterious halos.
Galactic Rotation and Gravitational Lensing
Galaxies observed through gravitational lensing show extreme light deflection that visible mass cannot explain. This research suggests that a modified 1/r gravitational potential could account for these effectsmatching observations traditionally used to support the presence of unseen cosmic substances.
| Feature | Standard Model (Dark Matter) | Infrared Running Model (Kumar) |
| Primary Force | Inverse Square Law (1/r²) | Deviating Long-Range Force (1/r) |
| Hidden Component | Cold Dark Matter Halos | Subtle Features of Gravitation |
| Theoretical Basis | Particle Physics | Quantum Field Theory |
- Rotation Curves: Explained by modified gravity strength rather than hidden mass.
- Gravitational Lensing: Potentially accounted for by the 1/r force law.
- Early Universe: Minimal gravitational shifts preserve precision cosmological measurements.
Scientific importance and theories
Kumar’s research is significant because it challenges the necessity of undiscovered particles that have eluded detection for decades. By linking galactic dynamics to quantum gravity’s scale dependencethe study offers a theoretical alternative that preserves early-universe cosmological measurements while explaining late-epoch observations.
Bridging Quantum Fields and Cosmology
This framework successfully maintains agreement with early-universe constraints while introducing corrections that only become relevant at later epochs. It ensures that the physics governing the cosmic microwave background remains intact while explaining the modern structure of the universe.
Implications and what comes next
Future investigations will compare this modified gravity theory against data from galaxy clusters and advanced lensing surveys. While not yet a full replacement for standard modelsit invites scientists to re-evaluate the origin of gravitational effects and the complexity of space-time.
Conclusion
Gravity’s hidden complexity may finally explain phenomena once attributed to invisible matteroffering a simpler view of the cosmos. Continued research will determine the validity of these scale-dependent models. Explore more astrophysics discoveries on our YouTube channel—join NSN Today.
