Five things you need to know about the Earth getting lighter

A A

Did you know that planet Earth is getting lighter in weight day-by-day?

In fact, it’s getting 50,000 tonnes lighter every year regardless of the 40,000 tonnes of space dust that falls on our planet’s surface annually.

Why/how is this possible?

Cambridge University’s Dr. Chris Smith and physicist Dave Ansel have come up with a few calculations to prove this.

Here are five things you need to know:

1. What causes the Earth to gain tonnes of weight per year?

• The Earth gains approximately 40,000 tonnes of dust a year due to the remains of the formation of our solar system. In short, our earth is indulging on too much star dust. So far, no diet plans have been addressed.

Planet Earth gains about 160 tonnes of matter a year due to the rise in global temperatures. “If we are adding energy to the system, the mass must go up,” said NASA officials.

2. What effects does all this weight have on Earth? Do humans and rapid infrastructure play a role?

• The increase in population and infrastructure surprisingly doesn’t add any extra mass to planet Earth. Humans and things are already made with matter on the planet. So there is absolutely no real effect.

3. What causes Earth to lose tonnes of weight every year?

• Overtime, Earth’s core loses energy – the less energy, the less mass. Sixteen tonnes of energy escape planet Earth every year. This might sound troublesome but not to worry, it’s not losing much at all.

4. What are the major mass losses on Earth every year?

• Approximately 95,000 tonnes of hydrogen and 1,600 tonnes of helium.

5. Should we be worried?

• Although some of you may be concerned for Mother Earth, we are still on the safe side – hydrogen and helium are way too light that they get lost into space plus, it would take trillions of years for the Earth to diminish without hydrogen.
