How much would a person weigh on a neutron star?

Have you ever wondered how much a person would weigh on a neutron star, one of the most extreme objects in the universe? Neutron stars are incredibly dense remnants of massive stars that have gone supernova, packing more mass than our Sun into a sphere just a few kilometers in diameter. This extreme density results in intense gravity, causing mind-boggling effects on the objects and individuals that dare to venture close.

Given the intense gravitational pull of a neutron star, a person standing on its surface would experience an unimaginable weight, far beyond anything we can comprehend on Earth. The incredible pressure and gravitational force exerted by a neutron star would squash both the person’s physical body and the very atoms that make up their existence, leading to a truly awe-inspiring and terrifying phenomenon.

What is a neutron star?

A neutron star is formed as the remnants of a massive star after a supernova explosion. It is an incredibly dense celestial object that is composed primarily of neutrons. With a circumference of only a few kilometers, a neutron star possesses an immense gravitational pull, making it one of the densest objects in the universe.

The extreme gravity of a neutron star

The intense gravity of a neutron star is what sets it apart from other celestial bodies. Due to its small size and high mass, the gravitational force on the surface of a neutron star is exceptionally strong, approximately two billion times that of Earth’s gravity.

Calculating weight on a neutron star

To understand how much a person would weigh on a neutron star, we need to compare it to the gravitational force we experience on Earth. On Earth, the average gravitational acceleration is approximately 9.8 meters per second squared (m/s^2). This means that a person weighing 70 kilograms on Earth would experience a gravitational force of approximately 686 Newtons (N).

To determine the weight on a neutron star, we can use the formula:

Weight on Neutron Star = Mass × Neutron Star’s surface gravity

Substituting the values, if we consider a person’s mass to be 70 kilograms, the equation would be:

Weight on Neutron Star = 70 kg × 2,000,000,000 m/s^2

The result of this calculation gives us an astonishing weight of:

140,000,000,000,000,000 Newtons (N)

The impact on the human body

Such an enormous weight would exert an unimaginable force on the human body. The strong gravitational pull of a neutron star would compress the body to an extreme degree. Every part of the body, from the bones to the internal organs, would experience a tremendous amount of pressure.

The immense gravity would cause the person to be flattened, almost like a pancake, due to the intense gravitational tidal forces. The crushing weight would likely be fatal, causing severe deformation and damage to the biological structure of the body.

Escape velocity and impossibility of standing

The escape velocity on a neutron star is also a vital factor to consider. Escape velocity represents the minimum velocity needed to escape the gravitational pull of an object. On a neutron star, the escape velocity is a substantial fraction of the speed of light, making it practically impossible for a person to stand or move freely on the surface.

The gravitational force on a neutron star is relentless, making it virtually impossible to resist its pull. Any attempt to stand would be futile as the force would instantly flatten the person.

Weighing oneself on a neutron star is an extraordinary thought experiment that highlights the incredible gravitational power of these celestial objects. While the actual experience is not physically possible for humans, understanding the forces at play can deepen our appreciation for the vastness of the universe and the sheer magnitude of the cosmic phenomena that exist within it.

A person would weigh an astronomical amount on a neutron star due to its extreme gravitational force, making it impossible for human life to exist in such an environment.
