Here's why:
* Weight vs. Mass: Weight is the force exerted on an object due to gravity, while mass is the amount of matter in an object. Your weight can change depending on the gravitational field you're in (like on the moon), but your mass remains the same.
* Schwarzschild Radius: The Schwarzschild radius is the radius around a massive object where the escape velocity equals the speed of light. Anything within this radius cannot escape the object's gravitational pull, forming a black hole.
To calculate the Schwarzschild radius, you need the object's mass in kilograms. Here's the formula:
* Rs = 2GM/c²
Where:
* Rs is the Schwarzschild radius
* G is the gravitational constant (6.674 x 10^-11 m³/kg s²)
* M is the mass of the object (in kilograms)
* c is the speed of light (299,792,458 m/s)
Let's imagine a hypothetical scenario:
If we assume a 200 lb man has a mass of roughly 90 kilograms (200 lb / 2.2 lb/kg), we can calculate his Schwarzschild radius:
* Rs = 2 * (6.674 x 10^-11 m³/kg s²) * (90 kg) / (299,792,458 m/s)²
* Rs ≈ 1.33 x 10^-25 meters
This incredibly small radius is far, far smaller than the size of an atom. It demonstrates that a human's mass is nowhere near enough to form a black hole.
To form a black hole, an object would need to be incredibly dense and massive, far beyond the scale of anything we encounter in everyday life.
