Astronomers can’t agree on how fast the universe is expanding. New approaches are aiming to break the impasse It is almost 100 years since scientists discovered the universe is expanding. In the decades that followed, the accuracy of the measurements, and interpretations and implications of this discovery, were a source of fierce debate. We now know the universe emerged dramatically from a highly compressed state in an event… The Conversation · Sep 19, 2024

Weird physics at the edges of black holes may help resolve lingering 'Hubble trouble' The expansion of the universe may not be accelerating at the edges of black holes. If this is the case at all event horizons, this may explain "Hubble tension," and the worst prediction in physics. Space · Jul 8, 2024
100 Years Ago, One Astronomer Massively Expanded Our Understanding Of the Universe Astronomers, maybe more than anyone, appreciate what an island of perfection our Earth is. In 1924, this appreciation took on a whole new level of undersatnding. Inverse · Jul 5, 2024
Scientists Share About The Possibility Of Existence Of Other Universes, People Are Intrigued Vera C. Rubin Observatory, with the largest camera ever built, might finally find evidence of the multiverse, which seemed like some kind of science fiction for decades.

The Hubble telescope has shifted into one-gyro mode after months of technical issues − an aerospace engineering expert explains Imagine keeping a laser beam trained on a dime that’s 200 miles away. Now imagine doing that continuously for 24 hours, while riding a merry-go-round. Seem difficult? Well, that’s basically what the Hubble Space Telescope does. The Conversation · Jun 17, 2024
Where is the center of the universe? The universe is undeniably vast, and from our perspective, it may seem like Earth is in the middle of everything. But is there a center of the cosmos, and if so, where is it? If the Big Bang started the universe, then where did it all come from, and where… Space · Jun 16, 2024
Scientists can’t agree on how fast the universe is expanding – why this matters so much for our understanding of the cosmos It’s one of the biggest puzzles in cosmology. Why two different methods used to calculate the rate at which the universe is expanding don’t produce the same result. Known as the Hubble tension, the enigma suggests that there could be something wrong with the standard model of cosmology used to… The Conversation · Jun 13, 2024
100 years ago, our understanding of the universe exploded Astronomers, maybe more than anyone, appreciate what an island of perfection our Earth is. Our orbit may put us at a perfect distance from the sun for life to flourish, but it is too small to easily help astronomers determine how big the universe is. The Conversation · Jun 12, 2024
A new theory of quantum gravity could explain the biggest puzzle in cosmology, study suggests A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests.

LiveScience · Dec 22, 2023 After 2 years in space, the James Webb telescope has broken cosmology. Can it be fixed? For decades, measurements of the universe's expansion have suggested a disparity known as the Hubble tension, which threatens to break cosmology as we know it. Now, on the eve of its second anniversary, a new finding by the James Webb Space Telescope has only entrenched the mystery.
LiveScience · Dec 22, 2023 'It could be profound': How astronomer Wendy Freedman is trying to fix the universe University of Chicago astronomer Wendy Freedman tells us how she's searching for an answer to the Hubble tension — a discrepancy between measurements of our universe's expansion that could threaten the dominant model of how the universe has grown since the Big Bang.
