english: Einstein's equations predict the size and shape of this ring, so taking a picture of it wouldn't only be really cool, it would also help to verify that these equations hold in the extreme conditions around the black hole.
non_english: Einsteinove rovnice predpovedajú veľkosť a tvar tohto kruhu, takže ak by sme ho odfotili, nebolo by to len fakt super, ale pomohlo by to overiť, že tie rovnice sú platné aj v extrémnych podmienkach okolo čiernej diery.
