Black Holes May Explode Into ‘White Holes’ And Pour All Their Matter Into Space, Physicists Say

Black holes might end their lives by transforming into their exact opposite — ‘white holes’ that explosively pour all the material they ever swallowed into space, say two physicists. The suggestion, based on a speculative quantum theory of gravity, could solve a long-standing conundrum about whether black holes destroy information.

The theory suggests that the transition from black hole to white hole would take place right after the initial formation of the black hole, but because gravity dilates time, outside observers would see the black hole lasting billions or trillions of years or more, depending on its size. If the authors are correct, tiny black holes that formed during the very early history of the Universe would now be ready to pop off like firecrackers and might be detected as high-energy cosmic rays or other radiation. In fact, they say, their work could imply that some of the dramatic flares commonly considered to be supernova explosions could in fact be the dying throes of tiny black holes that formed shortly after the Big Bang.

Big Bang Discovery May Bring ‘Theory Of Everything’ Closer To Reality

The discovery that the universe really did expand at many times the speed of light immediately after the Big Bang should bring physicists slightly closer to their ultimate goal — the long-sought “Theory of Everything.”

On Monday (March 17), researchers announced that they had detected the signature of gravitational waves in the cosmic microwave background, the ancient light that began pervading the universe 380,000 years after the Big Bang.

If it holds up, the landmark find confirms the theory of inflation, which posits that the cosmos exploded from mere quantum fluctuations into something of macroscopic size just a few tiny fractions of a second after its birth. [How Inflation Gave the Universe the Ultimate Kickstart (Infographic)]

The bottom part of this illustration shows the scale of the universe versus time. Specific events are shown such as the formation of neutral Hydrogen at 380 000 years after the big bang. Prior to this time, the constant interaction between matter (electrons) and light (photons) made the universe opaque. After this time, the photons we now call the CMB started streaming freely.
