[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! sky.esa.int/esasky/?hide_welco

What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

Sky survey boosts the case for dark energy’s downturn
It's looking more and more as if dark energy, the mysterious factor that scientists say is behind the accelerating expansion of the universe, isn't as constant as they once thought.

The latest findings from the Dark Energy Spectroscopic Instrument, or DESI, don't quite yet come up to the level of

Could the Big Crunch theory for the end of our Universe be coming back? Or is it Heat Death?

It's all a long, long way ahead of though, but I'll prefer a Crunch over a Heat Death, the Universe could be a cycle.

"A fundamental symmetry in physics, known as CPT (charge, parity, and time reversal) symmetry, implies that processes occur in mirrored pairs. In my model, this #symmetry ensures that when our universe emerges in one time direction, an anti-universe emerges in the opposite time direction. Although these two branches are classically separate, they remain quantum mechanically entangled…"
