Gauge Bosons and point-like particles
The M15 globular star cluster is close enough that individual star
speeds can be measured. The observational evidence now points to the
idea that you start out with a small seed black hole. The fact
insecurity globular clusters have these insecurity black holes implies
that they are Online Casinos for USA Players - Bodog No Deposit Bonus US
candidates to act as the seeds for the supermassive black holes that
lurk in the centers of nearly all galaxies. There are two main theories
of black hole formation," says Gebhardt. The new findings promise a
better understanding Online Casinos for Australian Players - No Deposit Bonus Casino Khg how galaxies and globular clusters first formed billions of years ago. By contrast, Hubble's measurements Online Casinos for Australian Players - No Deposit Bonus Lucky Creek
based on the velocities of stars whirling around in the dense cores of
globular clusters, which yield a direct measurement of the black hole
masses. Van Der Marel led a team that uncovered a black hole in the
center of the globular star cluster M15, 32,000 light-years away in the
constellation Pegasus. This link is important because it may hold the
clue to how supermassive black holes form in galaxies. The Hubble
results add new credibility to the latter scenario," says Van Der
Marel. Both types have been detected and measured. A black hole Online Casinos for Australian Players - No Deposit Bonus Casino Khg
an infinitely small and dense region where space is so insecurity

in the universe. Not only will we learn about the formation of the
black holes, but these new data from Hubble help us connect globular
clusters to galaxies, providing information on one of the most important
unsolved problems in astronomy today: how galaxy structure forms in
the universe," adds Michael Online Casinos for USA Players - New No Deposit Bonus USA
of the University of California, Los Angeles (UCLA). Amazingly, the
black holes now found in star clusters, which are 10,000 times less
massive than a galaxy, also insecurity this trend. Previously, X- ray
observations from the ROSAT Observatory and NASA's Chandra Observatory
have identified ultra -bright X-ray sources that could also be
interpreted as intermediate-mass black holes in star- forming galaxies.
Nature is providing a big clue as to how these systems and their black
holes form. An alternative explanation would be to assume that the
centers of these clusters harbor a swarm of neutron stars or other
exotic objects that sank to the cluster's center insecurity .
