Speculation in science.

Making calculations about the existence of other worlds, or other earths, is not something new, it is theorizing and making extrapolations, perhaps introducing some fantastic element, because when we do not have the data for that, we are talking about speculating, but From scientific speculation, speculative calculations can be made about what you can find in a certain area or place.

An example of this is the Drake equation, the Drake equation is a speculation based on scientific data, based on what we know, but what we know is unfortunately very little, the more data we have the more we can specify that equation. and the more we can adjust where to look for things, for example, in the past if you were an ice age hunter you could know, if you knew where a river was you obviously knew that there could be fish there, you could fish; If you knew where there was a meadow, you could calculate to speculate that there might be mammoths or other game there.

This scheme has always been done, one of the calculations of the existence of other lands, perhaps an example is the search for the land Australis, the one shown above, it would be all that mass of land that is down in the south, land Australia, It is southern land, the concept was introduced by the wise men of ancient Greece Aristotle and Eratosthenes, they already knew that the earth was spherical, that was already known a few centuries before Aristotle, I think but they believed that there should be a balance in a symmetrical balance between everything natural.

For this reason, they theorized that in the southern hemisphere there had to be other continents as extensive as those in the northern hemisphere, to balance what would be the masses of the earth and they called that supposed continent of the southern hemisphere Tierra Australis, by the way, It is the continent that appears on ancient maps and that also usually appears in some esoteric or conspiracy videos about ancient mysteries.

It was not a theory, it was a speculation, it was a Drake equation, they had calculated that there should be, if in the north there is so much land, in the south there should be a similar number of continents, it was not a real continent but one theoretically, these wise men were right, there is a balance of land masses between the northern and southern hemisphere, well no, because it turns out that they are very different, there is much more land mass in the northern hemisphere, this does not mean that in the past it was Thus, the continents are moving, the tonic plates move and have their dynamics and at this moment more land masses have accumulated in the north.

With this history of searching for the land australis, the first Portuguese explorers, who bordered Africa, then the Spanish, then the British and French as they discovered other interesting lands, discovered that Africa was more extensive than was thought in ancient Greece, which America was discovered for Europe, for Africa and Asia, Australia was also discovered, numerous islands were discovered and an icy continent, Antarctica, was discovered, which certainly seems to serve as a counterweight to those of the North, to the lands of the North although it was useless for colonization purposes. .

There was no such balance as the wise men of antiquity said, there was no land australis that had a balance in the amount of land with respect to the north but at least to find other lands and other continents and other places that were not known in ancient times.
