Scientists Say Universe Will Die Sooner Than Expected — But Don’t Panic Yet
A new study by Dutch researchers suggests the universe may meet its end far earlier than previously thought — though not anytime soon by human standards.
According to physicists at Radboud University, the final dissolution of the universe is now estimated to occur in 10⁷⁸ years — a one followed by 78 zeroes. That’s a drastic revision from earlier projections of 10¹¹⁰⁰ years.
“The final end of the universe is coming much sooner than expected, but fortunately it still takes a very long time,” said lead author Heino Falcke. The study was published in the Journal of Cosmology and Astroparticle Physics.
The recalculation centers on Hawking radiation, a theory proposed by Stephen Hawking in the 1970s, which suggests that black holes gradually lose mass by emitting radiation and eventually vanish. The Radboud team extended this theory to other celestial bodies, focusing on the universe’s most enduring remnants — white dwarf stars. They found that the “evaporation time” for such dense objects is far shorter than once believed.
“By asking these kinds of questions and looking at extreme cases, we want to better understand the theory, and perhaps one day unravel the mystery of Hawking radiation,” said co-author Walter van Suijlekom.
While the revised timeline alters our understanding of the cosmos, it doesn’t pose any immediate threat to humanity. Scientists already anticipate that Earth will become uninhabitable long before then — likely in about a billion years, when the Sun grows too hot and begins to boil the oceans. Around eight billion years from now, the Sun is expected to expand further and consume the Earth entirely.
So yes, the universe is dying faster than we thought. But we’ll be gone long before the lights go out.
