Milky Way's Heart Hides Darker Secret Than Black Hole, Scientists Claim

• New research challenges the long-held belief of a supermassive black hole, Sagittarius A*, at the Milky Way's center.
• Astronomers propose the galactic core might be an ultra-dense sphere of 'fermionic dark matter' instead of a black hole.
• This dark matter sphere, unlike a black hole, lacks an 'event horizon' but possesses a gravitational pull 4 million times stronger than the Sun.
• The study suggests dark matter could form a solid foundation in the galaxy's core, potentially rewriting astronomy textbooks.
• Future telescope observations could distinguish between a black hole's light ring and a dark matter core's altered or absent ring.
