“The mysterious boundary”

The entrance to a black hole could reveal insights into the Big Bang and the formation of galaxies.
“A black hole’s event horizon is a one-way bridge to nowhere, a gateway to a netherworld cut off from the rest of the cosmos.
“Understanding what happens at that pivotal boundary could reveal the hidden influences that have molded the universe from the instant of the Big Bang.
“Today some of the best minds in physics are fixated on the event horizon, pondering what would happen to hypothetical astronauts and subatomic particles upon reaching the precipice of a black hole. At stake is the nearly 100-year quest to unify the well-tested theories of general relativity and quantum mechanics into a supertheory of quantum gravity.
“But the event horizon is more than just a thought experiment or a tool to merge physics theories. It is a very real feature of the universe, a pivotal piece of cosmic architecture that has shaped the evolution of stars and galaxies. As soon as next year, a telescope the size of Earth may allow us to spot the edge of the shadowy abyss for the first time.
“By studying the event horizon through both theory and observation, scientists could soon figure out how the universe began, how it evolved and even predict its ultimate fate.”
