Two
black holes can merge to become a super massive
black hole.
Scientists recently witnessed a
black hole swallow a supersize snack--a neighboring star.
They do this either to avoid being put on
black hole lists themselves, to obtain a "friendly" email address, or to fool recipients about the source of the email.
Two teams of astro-nomers have discovered the first examples of large, isolated
black holes adrift among the stars of the Milky Way.
The team of international researchers who published their study in Science has proposed that massive
black holes were formed from supersonic gas streams left over from the Big Bang, and which then merged to form supermassive
black holes.
The reasoning goes something like this: If the two
black holes were spinning exactly aligned with the axis of their orbit, they would have needed to shed some of the system's total rotational energy before they could merge.
TEHRAN (FNA)- What happens when a
black hole falls on hard times?
The standard signal of merging
black holes is a chirp, named for the increase in frequency and amplitude of the gravitational waves produced as the
black holes spiral inward.
Washington, Oct 26 ( ANI ): A new method is set to focus on the difference of emission frequencies from molecules uniquely found around
black holes, which may open the way for "the search for a hidden
black hole" which is overcast with dust particles and optically invisible.
Here, the star-like
black hole with several solar masses (or several kilometers in radius) slowly grows up when it accretes materials from the outside and merges or packs with other
black holes, rather than impulsively explodes from nothing to something in the big bang theory.
