YOGYAKARTA - Buying and selling islands may have heard or known the information. But have you ever wondered what if the planet was sold. What is the price of the earth if it is sold or purchased by certain parties?
Planet Earth may be the most valuable asset we have, but the more appropriate term for describing it is "treasure". Natural resources and benefits given by Earth to humans are huge, so if it had to be left to another party, the losses incurred would be very significant and real.
Humans shouldn't have to consider whether Earth can be traded. However, imagining how much it would be worth if someone intended to buy it could help us realize how much Earth's true value is.
Reporting from Treehugger, a scientist has designed a special formula that allows us to estimate the value of the Earth. Based on calculations performed in 2020 by Dr. Greg Laughlin, a professor of astronomy at Yale University, Earth is estimated to be worth around US$5 quadrillion (equivalent to US$5,000,000,000).
The amount of the price of the earth is determined through an analysis of the mass of the Earth, temperature, age. In addition, the calculation of the value also considers various other factors that are directly related to its ability to support life.
As a form of affirmation of how valuable our planet is, Laughlin also calculates the value of other planets in the solar system based on their potential in providing resources for life.
Our closest neighbor, Mars, is estimated to be worth around US$ 16,000. The price value of the planet Mars is even cheaper than the current average used car price.
However, this figure is much higher than Venus, which Laughlin assessed is only worth one cent. Most likely this is due to extreme conditions on Venus, such as its atmosphere which consists of 96 percent carbon dioxide and strong winds that reach a speed of 320 kilometers per hour.
Laughlin himself does not mean that these numbers are used practically. Instead, he wants these calculations to encourage people to value more the only habitable place they have on Earth.
To date, humans have not been able to stay permanently on other planets besides Earth. Environmental conditions on other planets in the solar system are generally very extreme and do not support life as we know it.
However, from various studies and space explorations, Mars is often considered the most potential candidate to live in. Mars has a solid surface, a day-night cycle similar to Earth, and temperatures that, although cold, are still in a range that can be handled with certain technologies.
In addition, there is evidence of water in the form of ice beneath its surface which is one of the important elements to support life. Even so, the very thin Martian atmosphere dominated by carbon dioxide, as well as high cosmic radiation due to the absence of a protective magnetic field, poses a major challenge to the sustainability of human life there.
Scientists are also paying attention to the moons belonging to other planets, such as Europa (Jupitan moon) and Enceladus (Saturn's moon) because there are indications of ocean presence beneath its surface that may support the forms of microbial life. But so far, there has been no place beyond Earth that is truly worth living without the help of advanced technology and an artificial life support system.
