New research has improved the accuracy of the parameters that control the expansion of the universe. More precise parameters will help astronomers determine how the universe grew to its current state, and how it will evolve in the future.
Webb recorded what remained after the death of a star only 11 thousand light years away from us. It is a relatively new supernova - only 350 years old
Physicist Hikida from the University of Tokyo and his colleagues developed the dual model for Einstein's theory of gravity in three-dimensional de Sitter space. This is a significant step towards a model that will faithfully describe nature, i.e. the physics of quantum gravity under an expanding universe with a positive cosmological constant.

In my opinion, science surpasses any imagination, including Marvel's imagination.
