Where is the black hole research going – Axios

Details: One of the foci for advancing scientists will be to try to observe and understand the powerful jets of radiation and ultra-high-velocity particles that are ejected from black holes near the speed of light. Black holes are thought to be the source of some of the most energetic particles in the universe, known as cosmic rays.

Context: The photo, taken by the Event Horizon telescope, shows the shadow of the supermbadive black hole of the Messier 87 galaxy (M87) surrounded by a ring of light near the object's event horizon: the point at which nothing, not even light , you can escape from gravity. pull the black hole.

  • The ring consists of superheated gases known as plasma, which are formed as a result of the immense gravitational field of the black hole.
  • The material that goes towards the Earth seems brighter than the side that moves away.

Whats Next: Sera Markoff, a member of the scientific board of EHT and theoretical physicist at the University of Amsterdam, tells Axios that even with the new discovery, scientists still have a limited understanding of black holes.

"I am very interested in this interface with theoretical physics, and what are black holes really?" Markoff tells Axios.

"We know that Einstein was right in a general sense, but we do not really understand why gravity works like it does on a really microscopic level, how does it work, gravity is not a force like the others … in general it explains how It works, but it does not answer why. "

Markoff says that jets that are "literally rooted in the black hole" could be used to discover something fundamental about the nature of spacetime. "So we're not there yet, but there's a lot that's going to come out of this," she says.

The intrigue: "The most exciting thing we could do would be to impersonate Einstein, find that there is something a bit new in this extreme gravitational lab," said Avery Broderick, an astrophysicist with the EHT team, at the press conference.

  • "The problem of quantum gravity remains unresolved with the current tools we have, and black holes are one of the places to look for answers," said Broderick.

Where is it located Currently, EHT consists of 9 radio telescopes in 7 sites, including those in Antarctica and Greenland.

  • The EHT team plans to add 2 more to the mix by 2020 and is putting together proposals for a space telescope to improve the ability to probe the secrets of black holes.
