It sounds like something out of a sci-fi nightmare, but scientists are now saying the universe could meet its ultimate end far sooner than we ever imagined.
A new study published in the Journal of Cosmology and Astroparticle Physics is shaking up long-held beliefs about the lifespan of everything we know. For decades, experts believed the universe would limp along for an almost incomprehensible 10¹¹⁰⁰ years before fading into nothingness.
Now? That timeline has been slashed — dramatically.
Researchers from Radboud University say the real number is closer to 10⁷⁸ years. That’s still an absurdly long time, but compared to previous estimates, it’s like the universe just got hit with a cosmic fast-forward button.
And the reason behind this jaw-dropping revision traces back to one of physics’ most mind-bending ideas: Hawking radiation.
First proposed in 1975 by legendary physicist Stephen Hawking, the theory suggests black holes aren’t eternal monsters swallowing everything forever. Instead, they slowly leak energy over time, eventually evaporating into nothing.
Here’s where things get even wilder.
The team behind the study — including black hole expert Heino Falcke — believes this process doesn’t just apply to black holes. According to their research, everything in the universe with a gravitational field could slowly evaporate in a similar way.
That means stars, planets, and even the remnants of dead stars aren’t safe.
One of the most shocking findings involves so-called white dwarf stars — the dense leftovers of stars like our sun. Scientists estimate that about 97% of stars in the Milky Way will eventually become white dwarfs… and under this new model, they’ll all vanish after about 10⁷⁸ years.
To put that into perspective, the universe is currently about 13.8 billion years old. This new timeline still stretches far beyond that — but it’s astronomically shorter than what scientists once believed.
Falcke summed it up bluntly: the end of the universe is coming much sooner than expected.
Don’t panic just yet, though. Even with this revised countdown, humanity isn’t exactly on the clock.
But in the grand scheme of the cosmos, the message is clear — nothing lasts forever, not even the universe itself.
