Dark energy 'doesn't exist' so can't be pushing 'lumpy' Universe apart

Space and time from Science Daily Feed - Fri, 12/20/2024 - 10:30am
One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is growing equally in all directions. They employed the concept of dark energy as a placeholder to explain unknown physics they couldn't understand, but the contentious theory has always had its problems. Now a team of physicists and astronomers are challenging the status quo, using improved analysis of supernovae light curves to show that the Universe is expanding in a more varied, 'lumpier' way.

ESA and NASA satellites deliver first joint picture of Greenland Ice Sheet melting

Space and time from Science Daily Feed - Fri, 12/20/2024 - 10:28am
Scientists have delivered the first measurements of Greenland Ice Sheet thickness change using data from ESA and NASA ice satellite missions. With global warming causing the Greenland Ice Sheet to melt and flow more rapidly, raising sea levels and disturbing weather patterns across our planet, precise measurements of its changing shape are of critical importance for tracking and adapting to the effects of climate warming.

First demonstration of quantum teleportation over busy Internet cables

Computers and Math from Science Daily Feed - Fri, 12/20/2024 - 10:26am
Quantum teleportation could provide near-instant communication over long distances. But, inside Internet cables, photons needed for teleportation are lost within the millions of light particles required for classical communications. A new study quantified light scattering to find exact areas to place photons to keep them safe from other particles. The approach successfully worked in experiments carrying regular Internet traffic.
