Cosmic surveys suggest the force pulling the universe apart might not be constant after all.
Imagine sitting in the center of a firework that has just exploded. After the first flash of light and heat, sparks fly off in all directions, with some streaming together into fiery filaments and others fading quickly into cold, ashy oblivion. After a moment more, the smoke is all that remains—the echo, if you will, of the firework’s big bang.
A possible solution to the dark matter problem.
As the early universe cooled and expanded, phase transitions might have left “bubble walls,” energetic barriers between pockets of space.
Physicists and cosmologists will have a new probe of primordial processes when Europe launches the Laser Interferometer Space Antenna (LISA) next decade.
The “crisis in cosmology,” sparked by differing measurements of the universe’s expansion, may be nearing a resolution thanks to the James Webb Space Telescope. New data analyzed by scientists suggests that the Hubble tension might not be as severe as previously thought. This could mean our current model of the universe remains accurate.
The Debate on the Universe’s Expansion Rate
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number — known as the “Hubble constant” — have come up with different answers, leading some to wonder if there was something missing from our model of how the universe works.
Vast amounts of water found on Mars, but there’s a catch, Milky Way and Andromeda might not merge after all, a planet found before it gets destroyed, and an easier way to terraform Mars.

The two planets came as close as within a quarter-of-a-degree, or about 50% of the angular size of the lunar disk.
Lorenzo Di Cola also captured the conjunction over L’Aquila Italy. Both Jupiter and Mars were visible to the naked eye in the constellation Taurus during the cozy meet-up.
The photographer also took this amazing composition image made up of nine interval timer photos showing the two planets rising through the sky. Mars and Jupiter are visible in conjunction and if you look carefully you can even see some of Jupiter’s moons.
Shooting timelapse is a complex process that requires skill and patience, which an astrophotographer considers to be the most important thing for its creation.
Scientists Can Now Test for Extra Dimensions and Unveil New Realities with the LHC
TL;DR
The Large Hadron Collider (LHC) is pushing the boundaries of physics by enabling scientists to search for the Higgs Boson, explore the mysteries of dark matter, and potentially detect evidence of extra dimensions. Despite wild conspiracy theories claiming the LHC could open portals to parallel dimensions or create black holes, the reality is grounded in groundbreaking scientific exploration. The LHC may even briefly produce microscopic black holes, offering insights into the existence of extra dimensions without any danger to our planet. These discoveries could revolutionise our understanding of the universe.
