Summary
In this podcast episode of StarTalk, Neil deGrasse Tyson and Chuck Nice discuss various topics related to black holes and dark energy. They answer questions from Patreon supporters, including one about Hawking radiation and the eventual evaporation of a black hole. They also explore the singularity of a black hole and the need for a new theory to replace Einstein's theory of relativity. The hosts also discuss the potential use of black holes as wormholes for intergalactic travel and the concept of white holes, which were explored in the 1970s but ultimately abandoned due to lack of evidence.
The hosts also address the question of how massive jets of x-rays can come off of supermassive black holes when nothing can escape a black hole, including light. They explain that the accretion disk surrounding the black hole releases energy in the form of jets from the poles of the disk. The hosts also discuss the concept of dark matter and energy and whether they could be permeating into our universe from another nearby universe via black holes.
The hosts explore the possibility of a hunkering universe that is six times or more the mass of our own universe, and how its gravity could be seeping into our own universe. They also discuss the concept of dilution in different dimensions and how it affects the spread of energy and gravity. Additionally, they address a listener question about whether time would be faster on a planet further from the black hole of our galaxy that inhabits intelligent life, and whether that planet might be more advanced due to a relative time difference.
Overall, this podcast episode provides a fascinating and informative discussion about black holes and dark energy, exploring various topics and answering listener questions in an engaging and accessible manner.
