US EditionBlack Hole Mission: The Trillion-Dollar Quest To Test Einstein
NONE, AUG 7 – Ultralight nanocrafts propelled by lasers could travel at a third of light speed to observe nearby black holes within 100 years, researchers say.
- Soon, astrophysicist Cosimo Bambi of Fudan University published in iScience a plan for ultralight nanocrafts propelled by lasers to reach a black hole within about a century.
- On April 10, 2019, the Event Horizon Telescope published the first-ever image of a black hole at Messier 87, followed by Sagittarius A* three years later.
- Data show nanocrafts weigh about a gram with a 10-square-metre sail, attached to light sails propelled by a ground-based laser, aiming for speeds of up to 100 million miles an hour.
- Without a nearer black hole, Bambi cautions a Hyades cluster mission would take at least 420 years, and potential black holes could lie 20 to 25 light-years away.
- Such a mission could provide, as the scientist told ScienceAlert, 'I would hope to observe deviations from the predictions of general relativity and some clues to develop a theory beyond general relativity,' which could test Einstein's theory in extreme gravity.

Black holes are one of the great enigmas of the universe. Not even the brightest minds of modern physics have been able to unravel what exactly happens within them, where a point of infinite density known as singularity is hidden. Nor is it known what happens when crossing its limit, the so-called horizon of events. There are several theories, certainties, almost none. Known by a gravitational force so intense that not even the light can escape,…
