“The ‘big bounce’ –a cyclical expanding and contracting Universe–is more popular with general audiences than among working cosmologists,” theoretical physicist Matt Caplan told The Daily Galaxy. “The current best models,” he noted, “suggest the universe will expand forever and undergo a ‘heat death’. While people write papers about the possibility of a big bounce (and these get lots of press coverage) they should be regarded as speculation. Until we have a measurement that demonstrates unequivocally that the equation of state of dark energy is changing with time then a big bounce is no more likely than a big rip or big crunch (all of which are inconsistent with the standard model of cosmology).”

In February 2001, an eruption from the Surt volcano on the hellscape of Jupiter’s moon, Io, the volcanic epi-center of our solar system, exploded with an estimated output of an almost incomprehensible 78,000 gigawatts. By comparison, the 1992 eruption of Mount Etna, Sicily, was estimated at 12 gigawatts. During its peak, observed by the WM Keck II Telescope on Hawaii, its output almost matched the eruptive power of all of Io’s active volcanoes combined.
All the light in the observable universe provides about as much illumination as a 60-watt bulb seen from 2.5 miles away. And all the energy ever radiated by all the stars that ever existed is still with us, filling the universe with a sort of fog, a sea of photons known as the extragalactic background light.
