Musselburgh's revolutionary golf hole standardization took a while to catch on across the golf world.

Is SGR A a black hole?
Since the 1980s it has been evident that the central component of Sgr A* is likely a black hole. Infrared and submillimetre spectroscopy by a Berkeley team involving Nobel Laureate Charles H. Townes and future Nobelist Reinhard Genzel showed that the mass must be very tightly concentrated, possibly a point mass.
Is Sagittarius A a black hole?
In a paper published on October 31, 2018, the discovery of conclusive evidence that Sagittarius A* is a black hole was announced. Using the GRAVITY interferometer and the four telescopes of the Very Large Telescope (VLT) to create a virtual telescope 130 metres in diameter, astronomers detected clumps of gas moving at about 30% of the speed of light. Emission from highly energetic electrons very close to the black hole was visible as three prominent bright flares. These exactly match theoretical predictions for hot spots orbiting close to a black hole of four million solar masses. The flares are thought to originate from magnetic interactions in the very hot gas orbiting very close to Sagittarius A*.
Where is Sagittarius A located?
It is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic.
When was Sagittarius A discovered?
Later observations showed that Sagittarius A actually consists of several overlapping sub-components; a bright and very compact component Sgr A* was discovered on February 13 and 15, 1974, by astronomers Bruce Balick and Robert Brown using the baseline interferometer of the National Radio Astronomy Observatory.
Why can't we see SGR A*?
Astronomers have been unable to observe Sgr A* in the optical spectrum because of the effect of 25 magnitudes of extinction by dust and gas between the source and Earth. Several teams of researchers have attempted to image Sgr A* in the radio spectrum using very-long-baseline interferometry (VLBI).

How fast is S2?
In July 2018, it was reported that S2 orbiting Sgr A* had been recorded at 7,650 km/s, or 2.55% the speed of light, leading up to the pericenter approach, in May 2018, at about 120 AU (approximately 1,400 Schwarzschild radii) from Sgr A*.
