Universe decays faster than thought, but still takes a long time

SMRTR summary

In a cosmic revelation, scientists at Radboud University have calculated that the universe is decaying much faster than previously thought. The culprit? Hawking radiation, a phenomenon that causes even the most stubborn celestial bodies to slowly evaporate.

Lead researcher Heino Falcke notes, "The ultimate end of the universe comes much sooner than expected, but fortunately it still takes a very long time." Their calculations suggest white dwarf stars, the most persistent celestial objects, will decay in about 10^78 years - a far cry from the earlier estimate of 10^1100 years.

This groundbreaking study expands Stephen Hawking's theory beyond black holes, applying it to neutron stars and even the moon. Surprisingly, neutron stars and stellar black holes share the same 10^67-year lifespan.

While the universe's demise may seem distant, this research offers new insights into the nature of cosmic decay and the interplay of astrophysics, quantum physics, and mathematics.
