Spacetime With Stuart Gary

SpaceTime with Stuart Gary Gary - Series 29 Episode 3In this episode of SpaceTime, we delve into the latest discoveries in astrophysics and the challenges faced by space agencies worldwide.Ancient Supernova Offers Clues to Dark EnergyAstronomers have made significant strides in understanding dark energy, the enigmatic force driving the universe's accelerated expansion. A newly observed supernova, located 10 billion light years away, has been gravitationally lensed by a foreground galaxy, allowing scientists to analyze multiple images of the same explosion. This phenomenon could help determine the Hubble constant, shedding light on the universe's expansion rate and its ultimate fate, which ranges from a Big Crunch to a Big Rip.Sterile Neutrino Hypothesis Nearly Ruled OutAfter over a decade of research, scientists have come close to ruling out the existence of the sterile neutrino, a proposed particle that could explain anomalous neutrino behavior. Data from the Micro BooNE experiment at Fermilab has shown no s
