Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the mathematical framework used to describe cosmic expansion is inherently unstable and that the universe could accelerate naturally under Einstein's original theory of gravity. The findings also raise surprising questions about whether our location in the universe is as ordinary as scientists have long assumed.

NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk are performing a spacewalk to install the 7th of 8 ISS Roll-Out Solar Arrays (iROSA) to upgrade the orbiting outpost's power system.
Description This slice of Teghaza 001, one of the most ancient Martian meteorites ever found on Earth, was used to determine the age of the rock. Reflected light images like these serve as a scientist’s road map, helping them find minerals of interest to analyze by different instruments. Figure A is the same image with […]
NASA astronaut Anil Menon and Canadian Space Agency astronaut Joshua Kutryk successfully installed and unfurled the seventh of eight new solar panels designed to power the outpost through its retirement in 2030.
