Cosmic constants may explain away dark matter and dark energy
Sunday, 05 October 2025 22:53
For decades, astronomers have assumed that dark matter and dark energy dominate the cosmos. Now, new research from the University of Ottawa challenges that foundation, proposing that these unseen components may be illusions caused by the gradual weakening of nature's fundamental forces as the universe ages.

The newly identified source, RAD J131346.9+500320, lies at a redshift of about 0.94 - when the universe was roughly half its present age.

2025 marks a landmark year for Europe’s ‘bridge between Earth and space’. The European Space Agency’s Estrack satellite tracking network turns 50.
Since its inception in 1975, Estrack – ESA’s global network of ground stations – has formed the vital communication bridge between satellites in orbit and mission control at the European Space Operations Centre (ESOC) in Darmstadt, Germany.
Now comprising six stations spanning six countries, Estrack has grown into a strategic asset for Europe, enabling communication with spacecraft, transmitting commands and receiving scientific data.
The network keeps an eye on satellites no matter their location: tracking them across Earth
