Sagittarius A* is a supermassive black hole located at the center of the Milky Way. It has a mass equivalent to about 4 million suns.
Scientists study it using various telescopes, including the Event Horizon Telescope. Other black holes vary in size, from stellar-mass to supermassive. Thousands have been identified, some through gravitational wave detections. Pioneering scientists like Stephen Hawking and Roger Penrose significantly contributed to black hole theory.
Hawking proposed Hawking radiation, suggesting black holes can emit particles. Quantum mechanics, a fundamental theory, describes particles' behavior on a tiny scale, often defying classical intuition. For instance, the famous double-slit experiment illustrates particles' dual wave-particle nature, adding complexity to our understanding of the quantum world.
