the way we talk about science is constantly evolving.
That is why a team of researchers has come up with an idea that is unimaginable. Allow Pluto to shape its planet, according to a recent study published in the journal Icarus, as the criteria for revoking the status of its planets cannot be based on science.
While this is a source of hope for Pluto enthusiasts, it could come at a price: the moon must also be classified as a planet.
To include Pluto, we have to include the moon.
The definition of the word "planet" is strictly regulated by the International Astronomical Union (IAU). But that doesn't mean it's permanent and unchanged. It was drafted, amended and last given a strict definition in August 2006. According to this definition, an astronomical body qualifies as a planet if it has enough mass to take a spherical shape, and it has pushed local planets into its orbit. . And by these standards, our solar system has only eight planetary bodies: the classic Mercury, Venus, Earth and Mars, as well as the gas giant Jupiter, Saturn, Uranus and Neptune. Obviously, this leaves our little friend Pluto behind. And many people were not happy about that. Some scientists even responded to the IAU's move by suggesting that the definition be extended to focus on the physical characteristics of the planet under consideration.
And now a recent article reinforces the idea of revisiting the way planets are classified, arguing that the old methods are not really based on science but on folklore and astrology. If you have lost it, none of them are based on empirical evidence, and therefore do not state any objective facts independent of observation (primarily, because they cannot be disproved.) ). And a recent study, led by University of Central Florida planetary scientist Philip Metzger, led researchers to say that the definition of planets should go back to basics, and focus on one important factor: the cosmology. The body is in question. Geographically active. This will put Pluto back on the roster, but it comes with a very strange warning.
Scientific consensus is constantly reshaping the way we study the universe.
The proposed standard would describe many objects in the solar system as one planet, including our moon, and many other moons, dwarf planets, and even asteroids. This argument of excessive definition has been used in the past to prevent dissent from the existing system. But given the fact that these other entities have quite similar characteristics for grouping, researchers say there are many reasons to consider increasing the definition. In a blog post shared on the University of Central Florida website, Metzger said, "It's like admiring 'mammals'. They are animals whether they live on land or at sea. It's not about their location. It's about the inner qualities that make them what they are."
For five years, the team thoroughly analyzed the last 400 years of scientific literature on the planets, and discovered that Galileo's definition of the 1630s had gradually faded. The famous Renaissance man argued that the planets are just objects made up of elements that, like the earth, change over time. Recent research researchers have interpreted this to mean geological activity. Galileo's other condition was that the planets should reflect sunlight, rather than create their own. The definition of man continued until the 20th century, when the discovery of Pluto and the loss of interest in planetary science, "disrupted the transmission of the practical classification that descended from Galileo." Although we cannot say for sure whether Pluto will ever regain its former status as a planet from the IAU, it is studies like Metzger and his colleagues that tell us this. How many definitions and scientific consensus are formed in our observation, theory and way of thinking.
