China’s Massive Particle Accelerator –“Could Create a Phase Transition That Rips the Very Fabric of Spacetime”

 

 

China is building a particle accelerator that will be twice as large and seven times as powerful as CERN’s LHC and astrophysicist, Martin Rees, famous for his contributions to black hole formation to extragalactic radio sources and the evolution of the universe, thinks that there’s a chance the colliders could cause a “catastrophe that engulfs space itself”.

“Nixed?” –The Reality of Dark Energy and the Higgs Field

 

“The discovery of dark energy has greatly changed how we think about the laws of nature,” said Edward Witten,  one of the world’s leading theorists at the Institute for Advanced Study in Princeton, N.J.

ESA Mission Poised to Probe Mercury’s Mysteries –“With Implications for the Search for Life on Alien Planets”

 

Mercury’s magnetosphere could have implications for the search for life beyond our solar system. Exoplanets found orbiting cool red dwarf stars could host liquid water, and possibly life. But because they orbit their stars more closely than Mercury orbits the sun, they likely face strong stellar winds and radiation levels inimical to life, unless the planet is protected by a magnetosphere like Mercury’s.

“Presto!” NASA’s TESS Lights Up And Nets 73 New Stars and an Alien Planet –‘90% of the Sky is Yet to be Surveyed’

 

 

“The discovery of a terrestrial planet around a nearby M dwarf during the first TESS observing sector suggests that the prospects for future discoveries are bright. It is worth remembering that 90 percent of the sky has not yet been surveyed by either TESS or Kepler,” NASA reports.

The JWT –100 Times the Power of the Hubble Space Telescope “Inspired Revolutionary Material 1/10,000th of a Human Hair, at Temperatures Near Absolute Zero”

“When we first thought of Webb, it wasn’t technically feasible. We had to succeed at inventing some things before we could build it–not unlike the Apollo Program in this regard,” said Paul Geithner, Deputy Project Manager – Technical at NASA’s Goddard Space Flight Center.  “From an engineering perspective, Webb is extraordinarily difficult. The science means it has to be big, in space, and half of it has to be super cold. This means we had to design it to fold up for the ride into space, then have it unfold flawlessly by remote control. It also requires that we build the cold optics part exactly wrong, in gravity and air at room temperature, so that it will be exactly right–the right size and shape–when it’s weightless in the vacuum of space operating at temperatures so cold that air turns solid.”

Strange Triple-Star System Unique in the Cosmos –“A Laboratory for Einstein’s Theories”

“This is a unique star system,” said Ryan Lynch of the Green Bank Observatory in West Virginia, and coauthor on the paper. “We don’t know of any others quite like it. That makes it a one-of-a-kind laboratory for putting Einstein’s theories to the test.” This system contains a neutron star (image above) in a 1.6-day orbit with a white dwarf star, and the pair in a 327-day orbit with another white dwarf further away.
