Question
The high speed of formation of some of these non-light-emitting objects after the Big Bang influenced a cyclic model of the universe called the “Big Bounce.” For 10 points each:
[10e] Name these objects that have undergone gravitational collapse. “Supermassive” examples of these objects have weaker tidal forces near their event horizon.
ANSWER: black holes [accept supermassive black holes]
[10m] Work on supermassive black hole formation showed that larger-scale types of these structures like “Hot Torus” could assemble as quickly as smaller ones. The Gunn–Peterson trough in the spectra of these objects provides strong evidence for reionization.
ANSWER: quasars [prompt on active galactic nuclei]
[10h] Rapid supermassive black holes may evolve from these hypothetical black holes produced from external pressure after the Big Bang, thus allowing them more time to accrete.
ANSWER: primordial black holes [accept direct collapse black holes]
