The moon is a natural satellite of planet Earth and it has been creating doubts in us since our existence began and we encountered it. For many reasons, it has turned out to be the focus of various scientific studies over time. Thanks to these, today we know some details about it, we know how it was formed and what is on its surface, among other things. But, among many questions that surround this celestial body that is in the orbit of our planet, perhaps one of the most disturbing is what would happen if there were no moon? For this reason, in this article we are going to reveal to you what would be the consequences of this satellite suddenly disappearing and what would have happened if it had never existed.
How the moon was formed
It is important to know how this satellite originated, which has had so much influence on our existence, evolution and development of cultures. We know that planet Earth was formed almost 5,000 million years ago, specifically it is believed that it was 4.600 million years ago, and it did so from the cloud of gas and dust that originated our Solar System. Scientists have located the appearance of the moon on the timeline about 100 million years after the formation of the Earth, but how did it happen?
At that time, a celestial body the size of Mars, which scientists called there, impacted our planet causing a part of the Earth, which was then mostly magma, to detach from it and end up placed in its orbit.
Between the Earth and the moon there has since been a mutual gravitational attraction that produces an enormous energy movement. For this reason there are lunar tides and an energetic friction is created at the bottom of the waters of our planet. Due to the action of this attraction and the movement of energy that it creates, the Earth has been slowing down as it rotates on itself since the existence of this satellite. Therefore, the moon has exerted a brake effect on the movement of the rotation of our planet and, in fact, for this reason we currently have 24-hour days, since before its appearance the days on our primitive planet lasted only 6 hours.
At the time of its formation, this new satellite was much closer than now (currently it is 384,400 km), in fact it is believed that it looked between 10 and 20 times closer than we see it today. This was the reason that at that time the tides were much stronger than those we know today and, in addition, it is believed that these intense tides were vital for the life on this planet, about 4,000 years ago. Millions of years.
The tides would turn
Now that we have seen the origin of this natural satellite of our planet and its effect on it, we can begin to answer the question about what would happen if there was no moon. Or, what would happen if the moon disappeared?
We started by commenting on some of the most obvious things that would most likely happen. The tides would only have been produced by the effect of the sun, so they would have always been very slight, and probably life on this planet would have been almost impossible or it would have taken many more millions of years to begin to exist.
In the event that the moon disappeared, something very unlikely, the currents and tides would gradually weaken to the point that, with the sole effect of the sun, the water of our world would stagnate and there would be huge changes in the water level in the coasts. In addition, many living things that depend on these movements would disappear in a short time and there would be a spectacular change in the climate.
The axis of the Earth would vary
Another effect that would have the fact of not having or being left without the satellite on this planet would be that the axis of this would change completely. This is so because the movement of the moon in the orbit of the Earth helps to stabilize the axis of rotation of this on itself, in fact it always keeps it at 23º in the plane of its orbit. Thanks to this inclination in our world we know the different seasons throughout the year.
For all this, when the piece of our planet that detached the Their body disappears or does not exist, the movement of the Earth would become slower , as we have already pointed out before, and the axis of this rotation would be unstable , that is, it could vary from 0º to 90º. This would lead to serious changes in the weather on this planet and in the life that we currently know.
In addition, it is believed that the days, from having been at the beginning of about 6 hours to currently being 24 hours, would become only 8 hours.
Drastic climate change
In addition, due to the aforementioned changes, one of the things that would change and that would also change in the short term in a shocking way is the weather. There would be a change in the world’s climate and, in fact, it is believed that there could be very extreme temperatures from -80ºC to 100ºC.
In the event that the earth’s axis changes so much that the planet remains in alignment with the sun, the climate would be divided in two, that is, one part would be frozen, always dark, and the other insolated, always illuminated, permanently. Likewise, this would cause winds with speeds of more than 300 km / h among other extreme meteorological phenomena, such as spectacular earthquakes. Furthermore, there would never be lunar or solar eclipses.
Many living beings would cease to exist
To finish commenting on what would happen if there were no moon , it must be said that after all the negative effect that we have seen that this event would have, we can assure that both if life had been produced much later or if the change occurred now, life would be totally different from how we know it .
In addition, in the event that this satellite no longer exists in our orbit, both the fact that there would always be a dark sky at night, as if there were a new moon, as well as the great changes in time and tides, would cause many species of living beings, both animals and plants, will disappear completely. So there would probably be mass extinctions.
