Shocking Discovery: Universe Set to Decay in Just 10⁷⁸ Years—Far Sooner Than Scientists Expected!

The universe is decaying faster than we previously thought. New research by scientists from Radboud University in the Netherlands reveals that the last remnants of stars will take about (10^{78}) years to die out due to a process known as Hawking radiation. This estimate is much shorter than the (10^{1100}) years suggested before.

Insights from Researchers

The team includes black hole expert Heino Falcke, quantum physicist Michael Wondrak, and mathematician Walter van Suijlekom. Their findings were published in the Journal of Cosmology and Astroparticle Physics. This research builds on their earlier work, where they discovered that not only black holes but also neutron stars can "evaporate" through a process similar to Hawking radiation.

Hawking radiation, theorized by physicist Stephen Hawking in 1975, suggests that black holes can slowly lose energy. The new calculations show that some celestial bodies, like white dwarfs, will fade away much sooner than we thought.

The Implications

If we only consider Hawking-like radiation, the universe’s total collapse is estimated to occur in about (10^{78}) years. This is a big change: previous estimates did not account for this influence, leading to much longer lifetimes. Falcke states, “The end of the universe comes sooner than expected, but thankfully, it still takes a very long time.”

The researchers approached their calculations seriously but also with humor. Their reinterpretation of Hawking radiation sheds light on how different celestial bodies behave over time.

Surprising Findings

Interestingly, neutron stars and stellar black holes take about (10^{67}) years to decay, despite black holes having a stronger gravitational pull. Wondrak explains this anomaly: black holes reabsorb some of their own radiation, which slows down their evaporation.

In a bit of fun, the team calculated that both a human body and the moon would take around (10^{90}) years to decay via Hawking-like radiation. But they note that other factors could cause both to vanish much sooner.

A Multidisciplinary Approach

The collaboration between astrophysics, quantum physics, and mathematics has led to exciting new insights. Van Suijlekom emphasizes the importance of asking bold questions. This interdisciplinary approach may help scientists unlock the mysteries of Hawking radiation in the future.
