New Study Predicts Universe Will End in 10⁷⁸ Years Due to Stellar Remnant Decay

  • Three scientists from Radboud University in Nijmegen calculated in 2025 that the universe will end in about 10^78 years due to the decay of stellar remnants.
  • This finding revises previous estimates near 10^1100 years by including the evaporation of neutron stars and white dwarfs through Hawking-like radiation.
  • The researchers showed that massive objects leak energy via gravitational pair production, causing dense bodies like neutron stars to decay faster.
  • Lead author Heino Falcke explained that although the final conclusion regarding the universe’s fate occurs earlier than previously thought, this event remains extremely distant in the future.
  • This study implies even the most durable cosmic remnants will gradually evaporate, shortening the universe's lifespan while remaining far beyond human timescales.
