Huge Dust Particles Are Challenging The Laws Of Physics

Huge Dust Particles Are Challenging The Laws Of PhysicsMassive dust particles are being spread across the Earth and the source responsible is still unknown. This cryptic impact is so strong that it can move particles that are 50 times bigger than that of the expected size. The force is capable of moving these huge dust particles from the Sahara Desert to the tropical Caribbean.

For the past 30 years, scientists are studying the movements of small dust particles. It is well-known that the particles kicked up in the Sahara, often rides on global winds to the Caribbean which is 3,500 kilometers away. Earlier, this distant cloud of desert dust was believed to contain dust particles no bigger than 0.01 to 0.02 mm in diameter, but in recent observations, scientists have found that the overall size of these particles is defying their expectations.

The Royal Netherlands Institute for Sea Research found that some of the dust particles are measuring 0.45 mm in diameter which is almost 50 times bigger than what scientists have expected.

According to Giles Harrison, a researcher in atmospheric electricity at the University of Reading, the particles move fast from the Sahara Desert and travel through the continents and most people witness them as they settle on the cars. He added that current thoughts do not allow such giant particles to travel in the atmosphere for such huge distances. This suggests that there is some unknown atmospheric process that keeps them airborne.

Migration of these large particles could affect both the global climate system and even the overall cloud formation process. Enough accumulation of dust in the atmosphere can tip a delicate balance which thus changes the incoming sunlight and heat emission of the Earth and can impact both Earth’s weather and climate.

The calculation made as per the physical laws doesn’t allow particles bigger than 10 μm to travel such huge distances. The researchers are insisting on the future climate models.
