The Earth spins on its own axis, with each consecutive rotation marking a whole day on the planet. According to astronomer Jacco Van Loon, of Keele University, the reason the Earth hasn’t stopped spinning is that there is no force present to stop it. He compared it to a spinning top and noted that because there is little to no friction in space, there is nothing to push against the blue planet and slow down its course.
The moon is the only celestial body that actively slows down the Earth.
This is because the motion of the side of the Earth that is facing the moon is not balanced perfectly by gravity, and neither is the side of Earth facing away from the moon.
According to Mr Van Loon, this imbalance is the force responsible for the ocean tides, which make the oceans bulge out on either side of the Earth.
These waves constantly push against the Earth’s rotating, slowing the planet down and lengthening its day by one second every 50,000 years.
Mr Van Loon warned that the only thing that could stop the earth from spinning is if another planet crashed into it.
However, even if this happened, it is more likely that the impact would only change the way Earth spins, not stop it altogether.
If the planet ever stopped spinning, there would be numerous significant changes to life on earth, assuming we survived the impact of the massive planet that stopped the Earth in its tracks.
Mr Van Loon confirmed that humans wouldn’t be launched into space due to the strong gravitational attraction keeping humans grounded and quite down to Earth.
He also of a lot of changes, saying: “If Earth were to stop spinning but continue to orbit the sun, a ‘day’ would last half a year, and so would the night. It could warm up much more during the day and cool down much more during the night. This would affect the climate on Earth.
“A large temperature difference between day and night would cause strong winds, which would move warm air towards the cooler, nighttime side of the Earth.
“Wind would also blow from the warm regions around the equator to the cold polar regions.
“On a spinning Earth, this does not happen because the wind is deflected sideways.”

He warned that the eastwards and westwards winds, and the winds towards the poles, would meet, which could possibly create massive swirls of wind the size of entire continents.
There would also be significant changes to Earth’s magnetic field, which protects humanity against the most harmful aspects of solar radiation.
Mr Van Loon said: “Without the magnetic field, this radiation would reach the Earth’s surface and make people ill.
“Some birds use the magnetic field to find their way, so without the Earth spinning, they would get lost.”
