Planets could orbit singularities inside black holes

Certain black holes can have a complex internal structure that could allow photons, particles, and perhaps even planets to orbit the central singularity without ever getting sucked all the way in, Technology Review Physics arXiv Blog reports.

 

“Advanced civilizations may live safely inside the supermassive black holes in the galactic nuclei without being visible from the outside,” says Vyacheslav Dokuchaev, Institute for Nuclear Research of the Russian Academy of Sciences in Moscow.

 

Of course, such a civilization would have to cope with extraordinary conditions, such as huge tidal forces and the huge energy density that builds up in these stable orbits as photons become trapped.

Kevin KillionRegarding: We don??t think that we can do what we love and get paid for it, because of a beelif that we shouldn??t charge for something that we love to do. This is a common beelif among some people, particularly progressivists, who somehow think that somehow there is something wrong with business or earning a profit. It's hard to keep true to common sense when you have the spouse of the president of the United States tell a graduating class that instead of going into a business they should go into public service , meaning, working for a heartless bureaucracy on the taxpayers' dime. Earning a salary, making a profit, and having a successful business are positive indicators that you are performing tasks that other people want and need! Reply
