The Cosmic Conundrum: Earth's Rotation Post-Sun Vanishing and the Reality of Gravity

Introduction

The question of what would happen if the sun suddenly disappeared is a fascinating one, especially when considering the Earth's rotational dynamics. This thought-provoking inquiry challenges our understanding of gravity and Newton's laws of motion.

In this article, we explore the specific scenario of Earth's rotation and the impact of the sun's disappearance. We will also delve into the debate surrounding the nature of gravity and its supposed implications.

Understanding Earth's Rotation

The Earth is not spinning, but rather turning very slowly on its axis. According to Newton's laws of motion, objects in motion tend to stay in motion unless acted upon by an external force. In this case, the Earth's rotation is a result of its initial momentum and the balance of forces exerted by gravity and other celestial bodies.

Immediate Effects of the Sun's Disappearance

The moment the sun vanishes, the Earth's rotational energy would cease. This would happen in 8.5 minutes, the same time it would take for the sun's light to disappear from the sky. As a result, the Earth would immediately embark on a new trajectory, moving perpendicular to its former orbit at a velocity of 19 miles per second.

Gravity, a force described by Einstein's theory of general relativity and special relativity, moves at the speed of light (299,792,458 meters per second). Thus, the earth would experience this change in trajectory with the same speed at which the sun's light would take to reach us.

Challenging the Gravity Theory

One theory posits that the theory of gravity discussed in Einstein's theory of relativity might be flawed. Proponents of this view suggest that electromagnetism, rather than gravity, is responsible for keeping us grounded on the Earth's surface and preventing objects from flying into outer space. They argue that gravitational forces could be a charge phenomenon, similar to how electromagnetic forces reside between charged particles.

Nature of Gravity Revisited

From a Newtonian perspective, the moment the sun disappears, the Earth would instantly move in a straight line tangent to its previous orbit, according to Newton's concept of instantaneous gravitational force. However, this perspective would seemingly violate the principles of general and special relativity, which dictate that gravitational forces propagate at the speed of light.

In reality, a gravitational wave would be generated as soon as the sun disappears, traveling at the speed of light. Earth would begin to move along a new path, which would then appear as if it was orbiting a ghostly star where the sun once was. Mercury, the closest planet to the sun, would be the first to be affected, within 3.2 minutes of the sun's disappearance, followed by Venus within 6 minutes. The Earth would experience the gravitational ripple in 8.5 minutes, and Pluto would not be affected until nearly 5.5 hours later. The farthest known object, Ultima Thule, would be impacted around 6.2 hours after the sun's vanishing.

Conclusion

The scenario of the sun vanishing offers a unique opportunity to contemplate the true nature of gravity and the forces that govern our cosmic environment. While the Newtonian perspective on instantaneous gravitational forces is intriguing, modern physics relies on the understanding of general relativity and special relativity to provide a more comprehensive explanation of gravitational forces.
