The first DoubleTree hotel opened in Scottsdale, Arizona, in 1969. [13] It was located on the grounds of Scottsdale Fashion Square and was built by Sam Kitchell. [2] The DoubleTree Hotels Corporation merged with the Guest Quarters Hotels Partnership of Boston in December 1993. [14] The acquired hotels were rebranded under the DoubleTree name.
A network telescope (also known as a packet telescope, [1] darknet, Internet motion sensor or black hole) [2] [3] [4] is an Internet system that allows one to observe different large-scale events taking place on the Internet. The basic idea is to observe traffic targeting the dark (unused) address-space of the network.

The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
While in a non-rotating black hole the singularity occurs at a single point in the model coordinates, called a "point singularity", in a rotating black hole, also known as a Kerr black hole, the singularity occurs on a ring (a circular line), known as a "ring singularity". Such a singularity may also theoretically become a wormhole. [18]
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
