A space engineer from the University of Glasgow has proposed a solution in order to save the Earth from the Sun’s ire when it will burn out and expand until it reaches our planet’s orbit.
Human-induced climate change is an immediate interest, which means that an irreversible warning catastrophe seems increasingly likely. Even so, the Earth’s long-term forecast is even more dreadful, because the Sun will someday consume all of its fuel and expand, destroying our planet. This will apparently happen in five billion years. However, moving the planet to another orbit is a way to escape the dire fate, and an engineer has now suggested a few theories to do just that.
Astronomers know that the Sun will eventually change into a massive red star, way more extensive than its present size. This expansion will ultimately get to the Earth’s orbit, making it impossible to live in about five billion years.
However, space engineer Dr. Matteo Ceriotti from the University of Glasgow has suggested a few radical solutions to aid the planet move from its orbit. The suggestions have to be excessive, for instance, the Earth’s mass is so vast we do not dispose of sufficient power to move the planet using regular rocket propulsion.
The revolutionary proposals are mainly based on actual technologies, even though we can image that surviving human species will have considerably advanced science by then.
Dr. Ceriotti said that he created a thought experiment regarding the moving of the planet towards the orbit of Mars with the existing technology. This is about 1.5 times the ratio of Earth’s orbit at the moment, to save the planet.
One idea states that using the gravitational pull of asteroids passing by Earth to move our planet away from its current position. Dr. Ceriotti explained that this theory needs a considerable number of spacecraft to get to asteroids and then deflect them into an orbit near the Earth.
Another method would be to hit the asteroid with an ion laser, and the ion beam would push the space rock farther from its orbit. Other ways, such as the mass drive, involve landing on the meteor and turn on a rocket on its surface so it would generate material. The surface of the space rock will distill or transform into gas, and this material would create the force to move the asteroid.
However, the simplest method is called a ‘kinetic impactor,’ and it involves hitting the asteroid with a spacecraft. Asteroids aren’t the only option, even though they would be implicated in creating a solar sail, a large reflective layer that catches the momentum of light from the Sun and utilizes it to push the Earth forward. Dr. Ceriotti said that it would, though, need to have a considerable size, a few times the diameter of the Earth.
These ideas are basically founded on physics and the consideration of fundamental physics. This is not going to see much transformation in the following billions of years, and even though new technologies are and will be developed, the physics is not going to change, Dr. Ceriotti stated.
