Developed by Professor Rajendra Gupta and Dr. Nikolaos Samaras, the covarying coupling constants plus tired light framework modifies the Einstein and Friedmann equations. The model was tested against astronomical data throughout 2025 and 2026, successfully matching expansion rates derived from cosmic chronometer measurements. It also accurately reproduced the Big Bang's light element formations, such as hydrogen and helium, while explaining the rotation curves of 175 galaxies from the SPARC database without relying on dark matter.

- Summary:
- A provocative new cosmological model suggests the Universe could be 26.7 billion years old and might not need dark matter or dark energy to explain its behavior. University of Ottawa researchers tested the theory against several major astronomical observations, finding that it could explain galaxy rotation, cosmic expansion, and the formation of early elements.

A radical alternative to the standard picture of the cosmos is gaining attention after researchers at the University of Ottawa reported that it successfully matched several important astronomical observations. The model suggests that the Universe could be 26.7 billion years old, nearly twice the widely accepted age of 13.8 billion years, and that neither dark matter nor dark energy is needed to explain its behavior.
If further research supports these findings, the theory could offer a very different explanation for how the Universe evolved. It may also help resolve one of modern astronomy's most puzzling discoveries: the existence of surprisingly large and mature galaxies at a time when the…
The feature film explores Colin Pillinger's ambitious efforts to search for life on Mars through the ill-fated Beagle 2 lander. The production highlights the human perseverance behind the British spacecraft, which was long deemed lost until proof of its landing emerged posthumously. Audiences will see the story arrive in cinemas in 2027 under director Mackenzie Crook.
Researchers have unlocked a computational method that mines archival space telescope observations to spot previously obscured worlds without requiring physical hardware modifications. By creating an instrument digital twin that accurately models and subtracts blinding starlight, the breakthrough allows extremely faint celestial signals to finally become visible. This innovation paves the way for extensive re-analyses of existing deep-space datasets to extract previously missed planetary targets.
Defense officials are monitoring critical challenges related to orbital lift capabilities as national security demands face an increasingly constrained market. Continued readiness depends on maintaining reliable channels to space for defense assets, but current industry bottlenecks risk delaying essential government payloads. Ensuring adequate manifest capacity remains a primary operational focus for leadership moving forward.
