Dark energy may not exist; new evidence supports the 'timescape' model of cosmic expansion which explains the universe's acceleration without it.

Dark energy is the dominant energy source in the Universe, making up about two-thirds of its total energy and driving accelerated cosmic expansion.

Dark energy's acceleration of cosmic expansion may be evolving over time, challenging previous assumptions.

The Hubble tension reveals potential missing components in the cosmic expansion model.

Conflicting measurement rates of cosmic expansion rates remain unresolved.

Both teams highlight the need for refined measurements to clarify ongoing discrepancies.

The James Webb Space Telescope captured a unique image of a supernova that helps in understanding the expansion of the universe.

The disagreement over the rate of cosmic expansion persists despite recent observations using JWST.

The James Webb Space Telescope's observations provide conflicting values for the rate of cosmic expansion, failing to settle the disagreement over the Hubble constant.
