Cosmology

Physicists have demonstrated that the wave function describing the entire universe's quantum state cannot be determined through any experiment, even from a limited set of possibilities. Researchers Eddy Keming Chen and Roderich Tumulka argue this reveals a fundamental limit in quantum physics. Their work challenges assumptions about empirical knowledge in cosmology.

Scientists using the James Webb Space Telescope have produced the highest-resolution map of dark matter to date, based on distortions in 250,000 galaxies. This map uncovers previously unseen cosmic structures and could deepen understanding of the universe's evolution. The achievement highlights dark matter's dominant role, comprising 85 percent of the universe's matter.

Scientists at the University of Chicago have used weak gravitational lensing to map dark matter and dark energy across a vast sky region, confirming the standard cosmological model. By analyzing archival telescope images, the team expanded galaxy shape measurements, resolving debates about cosmic structure growth. Their findings align observations of the nearby universe with early universe data from the cosmic microwave background.

A new theoretical study suggests that the geometry of hidden extra dimensions could be the source of fundamental forces and particle masses, challenging traditional models like the Higgs field. Researchers propose that evolving seven-dimensional structures generate mass through intrinsic twists called torsion. This approach might also account for the universe's accelerating expansion and predict a new particle.
