- Scientists have spent an incredible amount of labor trying to determine what conditions support life and why the Earth is so perfect for living things.
- Now, a researcher simulated 100,000 planets to try to determine how lucky we are that the Earth has been habitable all along.
- It turns out that we are incredibly lucky that the Earth seems to have the habit of becoming habitable even after catastrophic events.
This shouldn’t happen for nothing, but just in case you haven’t raised it in a while, I’ll go ahead and mention it: we’re very, very lucky to live on Earth. Earth, as far as we know, is the only planet that has ever endured life and has done so for billions of years. This is an incredible success that places the Earth in a group of one.
However, this does not mean that life on Earth has always been easy. In fact, our planet has faced many extinction events during its tenure as a bastion for life. However, he has always managed to return things to a kind of balanced state. Of course, it may have taken millions and millions of years for this to happen, but it always happened fast enough for life to hold on and thrive once again. Now, a scientist has taken it upon himself to see how lucky we are that the Earth has survived for a long time without life being completely erased, and the data is incredibly interesting.

Like Phil Plait’s SYFY Wire reportedly, the experiment is the subject of a new article published in Communications Earth & Environment. In the paper, researcher Toby Tyrrell explains that the Earth, which remained habitable for three to four billion years, was what sparked his desire to do a lot of simulations and see how lucky the Earth is. Earth.
The Earth’s climate has remained continuously habitable for 3 or 4 billion years. This presents a puzzle (the “habitability problem”) because it seems that loss of habitability is more likely. Solar luminosity has increased by 30% in this time, which, if not counteracted, would have caused sterility. In addition, the Earth’s climate is precariously balanced and can deteriorate to the point of freezing in a million years. Here I present the results of a new simulation in which randomly generated climate comments were assigned to thousands of planets. Each planetary configuration was tested to see if it remained habitable for a period of 3 billion years. The conventional view attributes the extended habitability of the Earth only to stabilizing mechanisms. The simulation results shown here reveal that chance also plays a role in habitability results. Therefore, the long-term habitability of the Earth was probably a result rather than an inevitable result.
Tyrrell assigned mathematical values to the 100,000 virtual planets he simulated. The climate of each planet was randomized, as some would have Earth-like feedback loops: Earth with too much CO2 would cause too much heat, producing even more CO2, etc., while others would have different variations. The actual climates were not simulated, but the values representing the variables were assigned and each planet was tracked, simulating it 100 times.
The temperature of each planet was tracked for 3 billion (virtual) years. Of the total huge number of simulated planets, only one planet managed to remain habitable during the 100 simulations. Other planets remained habitable during some simulated tests, but not others, but only 9% of the planets remained habitable for at least a period of 3 billion years.
Needless to say, the fact that the Earth has been sustained through asteroid impacts, rapid cooling, and perhaps even one or two eruptions of supervolcanoes is very, very fortunate. If any of these events had ended my life completely, I wouldn’t be here writing this and not reading it.
