What Katie Freese has said

Physicist Katie Freese and collaborator Yun Wang re-analyzed data from the DESI experiment and found no strong evidence that dark energy is changing over time, contradicting the experiment's primary claim.

The existence of dark stars could potentially explain the formation of supermassive black holes in the early universe and other unexplained objects observed by the James Webb Space Telescope.

Expert perspectiveKatie FreeseApr 2

A new experimental effort called "paleo detectors" proposes to search for dark matter tracks in ancient rocks, such as Olivine, that have been shielded deep underground for up to a billion years.

Expert perspectiveKatie FreeseApr 2

String theory requires the existence of 10 spatial dimensions, and in some models our universe is a three-dimensional surface, or "brane," whose evolution can be influenced by interactions with these ...

Expert perspectiveKatie FreeseApr 2

A theoretical object called a "dark star" is hypothesized to be one of the first stars, made of ordinary matter but powered by dark matter annihilation instead of nuclear fusion.

Expert perspectiveKatie FreeseApr 2

The James Webb Space Telescope has observed candidate objects that could be "dark stars," a theoretical type of star powered by dark matter.

Expert perspectiveKatie FreeseApr 2

Gravitational wave detectors are observing merging black holes, some of which could be primordial black holes, which has renewed scientific interest in them as a dark matter candidate.

Expert perspectiveKatie FreeseApr 2

The formation of galaxies and other large-scale structures in the universe required dark matter to first collapse into gravitational halos, which then attracted ordinary matter.

Expert perspectiveKatie FreeseApr 2

The demand from large-scale dark matter experiments has led to the purchase of the entire world's supply of xenon, causing its price to increase significantly.

Expert perspectiveKatie FreeseApr 2

Paleo detectors could potentially be used to study the history of supernovae in our galaxy by analyzing the distinct tracks left by neutrinos in rocks of different ages.

Expert perspectiveKatie FreeseApr 2

Most current dark matter detection experiments use large vats containing tons of liquid xenon to search for interactions with dark matter particles.

Expert perspectiveKatie FreeseApr 2

Theoretical models predict that dark stars could grow to be a million times as massive as the sun and a billion times as bright.

Expert perspectiveKatie FreeseApr 2

The three leading candidates for the identity of dark matter are WIMPs (Weakly Interacting Massive Particles), axions, and primordial black holes.

Expert perspectiveKatie FreeseApr 2

Scientists are actively searching for the existence of purely dark matter galaxies, which would be invisible but detectable through their gravitational lensing effects on background objects.

Expert perspectiveKatie FreeseApr 2

The Dark Energy Spectroscopic Instrument (DESI) experiment has produced evidence suggesting that dark energy may be changing over time, causing the acceleration of the universe's expansion to slow dow...
