Physicists Simulated a Black Hole in The Lab, And Then
WEBA black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing.. Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists in 2022 observed the equivalent of what we call Hawking radiation – particles born from disturbances in the quantum fluctuations caused …
Our Galaxy Could Be Falling Into a Colossal 'Basin of Attraction' …
WEB9 hours ago · The CosmicFlows data suggest that we could be part of the Shapley Concentration, which could be 10 times the volume of Laniakea. It's about half the volume of the largest structure in space, known as The Great Wall, which is a string of galaxies stretching across 1.4 billion light-years. Several superclusters were revealed by the 2dF …
Microbes Found Alive Sealed in Rock For 2 Billion Years
WEB11 hours ago · This formation is huge, a 66,000 square kilometer (25,500 square mile) intrusion into Earth's crust that formed some 2 billion years ago from molten magma cooling below the surface. Suzuki and his colleagues thought that the rock's formation and evolution over time was likely to be conducive to long-term habitability for microbes.
Nearby Dwarf Planet Could Have a Crust That's 90% Water
WEBA dwarf planet thought to have some ice mixed in with its dirty surface may have a lot more cool than we ever expected. Ceres – the largest body in the asteroid belt between Mars and Jupiter – could have a crust consisting of more than 90 percent water ice. If this is the case, the heavily cratered and scarred object could have a lot to teach us about ocean worlds, …
The Early Universe Could Have Been Full of Very Dark Holes
WEB3 days ago · One such mechanism is a "direct collapse", in which early structures of the unknown, invisible substance known as dark matter confined gas clouds, while background radiation prevented them from forming stars. Instead, they collapsed into black holes. The trouble is that only a minority of dark matter halos grow large enough to form such seeds.

WEBEarth's interior structure consists of a series of concentric layers, from the crust to the core. At the very center, with a radius of about 1,227 kilometers (762 miles) is the inner core – the densest part of our planet, a solid ball mostly composed of iron and nickel, comprising less than 1 percent of Earth's volume.

WEBSep 5, 2021 · An international team of astronomers flipped it again in 2018 and found that a planetary nebula is indeed the most likely solar corpse. The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the ...
