✓ Black Hole size comparison in the Universe
• This animation from NASA shows some of the best-known black holes compared to other cosmic objects and our sun is also in comparison to them.
Additionally,
• A black hole is a region in space where gravity is so strong that nothing, not even light, can escape its gravitational pull. It is formed when a massive star falls down under its own gravitational force at the end of its life.
• The collapse ensues when the star depletes its nuclear fuel and can no longer sustain the outward pressure generated by the fusion reactions in its core. Without this pressure to counterbalance gravity, the star collapses inward, compressing its mass into an extremely dense and compact object.
• The core of the collapsing star becomes infinitely dense, creating what is known as a singularity. This singularity is surrounded by an event horizon, which is the boundary beyond which nothing can escape. The event horizon acts as an invisible surface, and anything that crosses it, including light, is trapped inside the black hole.
• Black holes have several properties, encompassing mass, spin, and electric charge. These properties specify their effects on the surrounding space and matter. For example, black holes can distort spacetime, inflicting gravitational waves, and they can also pull nearby matter into a swirling disk known as an accretion disk.
• Black holes play a significant role in astrophysics, as they are thought to be accountable for a range of phenomena, such as powering active galactic nuclei, generating gamma-ray bursts, and impacting the formation of galaxies. They also provide scientists with opportunities to study the fundamental laws of physics, as they test the limits of our current understanding, especially regarding the behaviour of matter and gravity under extreme conditions.
