Future of black hole research

Black holes are some of the strangest and most fascinating objects found in the Universe. While black holes are predictions of Einstein’s theory of gravity (one hundred years ago), even he did not imagine that such exotic objects could exist.

Only recently, in April 2019,  the first ever picture of a black hole has been made by the Event Horizon Telescope (or EHT) consortium: the first direct proof of the existence of a black hole in the centre of the elliptical galaxy M87.

It was ground breaking in many ways:

  • It presents the direct evidence for the existence of black holes, showing that Einstein (and hence the theory of General Relativity) was right,
  • It shows the first ever image of lensed and relativistic beamed emission on the scale of the event horizon in extreme gravity,
  • And it helps to constrain models for jet formation and energy extraction from black holes

More observations are required to further constrain the models, to monitor the variations of the flow of matter in extreme conditions on different timescales and to image the black hole in the centre of our own galaxy (Sgr A*).

And although new telescopes for the EHT network already are foreseen in the near future, a fundamental gap on the world’s map remains: Africa.
