Observational confirmation of the Cygnus X-1 binary, suspected since about 1971 of being a black hole, came from a space and land-based radio and x-ray instruments in 1972, and was widely accepted as a black hole by 1973.

Yes. The most up-to-date cosmological theories state that a black hole is far more likely to be rotating (spinning) than not.
In this case, you would typically give the first day of your last period as the date when your period was originally due, not the spotting date. Since you spotted 4 days before your expected period, you would count back to that day, which would be the first day of your last menstrual period (LMP). This is usually how healthcare providers calculate gestational age and due dates.

There are currently space-born science packages that are searching for this very event - detection of such has not been successful to date but NASA's FGST gamma ray telescope launched in 2008 is looking for what is believed to be the characteristic light flash from them.
That depends. The smallest black holes known are generated by the collapse of massive stars, so the holes themselves tend to be rather massive--on the order of the mass of a star. Most galaxies contain black holes that mass hundreds of thousands to billions of times that of our sun. Sagittarius A, our Milky Way's black hole, is a little over four million solar masses. It is possible quantum black holes formed during the big bang. These would have been tiny singularities, with masses measured on the atomic scale. Stephen Hawking demonstrated fairly effectively such black holes would have preferentially absorbed charged particles from the quantum foam, bleeding mass until they evaporated. It is unlikely any would now be left from 13.7 billion years ago.
Yes she will but may b not as a first boyfriend
Black you can never go wrong with black hope this helped! TT Cullen
29th of August 1588. It was spotted off the Lizard, Cornwall.
Miley was spotted recently on a date with her ex-boyfriend, Liam Hemsworth.
No but the two were spotted kissing backstage at a T.I. concert in 2009
May 18, 1861; December 4/5, 1872; and April 5, 2001 are dates upon which Mary Celeste first was spotted. The first date references that of the hermaphrodite brig's launching under the original name of Amazon whereas the second date refers to the part-barkentine part-schooner's discovery by the captain and crew of Dei Gratia. The third date refers to the remains of the half brig being found under a shanty-laden, shell-built artificial island off Haiti by marine archaeologist Clive Cussler and professional divers Mike Fletcher and John Davies.
