  • Does Chameleon Gravity Hide in Cosmic Voids?

    Does Chameleon Gravity Hide in Cosmic Voids?
    2025/06/27

    Are these the voids you're looking for?

    Season 2 kicks off with a bang! Thomas explains a paper he co-authored in the Journal of Cosmology and Particle Physics, exploring the question of whether chameleon screening could be part of the answer to how modified gravity might work? Where would you look to find out if high density regions might turn off modified gravity effects? Cosmic voids of course!


    Could this point to a fifth force that's pushing the universe apart?
