This image was published on March 17 by the European Space Agency. It is an experiment aboard a MASER rocket launched from the Esrange space center in Kiruna in the north of Sweden. The experiment was launched in 2022 but the analyzes have taken time and have been published recently.
The idea was to find out how the dust particles begin to group together to create an embryo of a planet or star, the photo, the curious one shows a planet embryo, obviously it is not going to go any further than what it has reached here, but it shows us how the particles can come together in space in a situation of weightlessness or microgravity, the correct thing is to say microgravity because you already know that gravity is everywhere and it is diluted with distance but in space there is no weightlessness. There is totally gravity of both the Sun extends to the Earth's gravity, evidently extending beyond the Moon.
To not have the influence of gravity you would have to go to one of those interstellar voids that exist and that are very mysterious and strange to really be in weightlessness, you would have to go to one of those places, but in general the correct term is microgravity, the important thing is that what they did was take a container into space with tiny particles that spent about 6 minutes in microgravity and also without disturbances while the rocket went up and down from 260 km.
The question was how do they group together because well in microgravity all those thousands of particles move freely and what they do is what any particle that is moving freely does, as if in a crazy dance they collide with each other, but the curious thing is that some of them, instead of being thrown away by the impact, which would be the logical thing, what they did was group together and quickly ended up forming clumps like this one about 3 cm in diameter.
How is this possible? The logical thing is that no planets or stars would have formed either, the particles inside those clouds, even if they collapse, would be constantly hitting each other, they would have to be compressed much more to collapse completely, however, we see that in weightlessness a cloud of particles is capable of forming clumps, you don't need to put too much pressure on it, because this cloud of particles was a cloud of particles here on Earth and in space in less than 6 minutes these clumps managed to form.
The curious thing about this question is precisely the electricity, it turns out that gravity does not act here, the mass of the dust motes is insignificant, it is negligible. Gravity really only begins to be important when an asteroid exceeds a kilometer in diameter, the key is in the speed, this is what they have discovered in this research.
The key is in the speed, size and electricity, the researchers discovered that the speed and size of the particles were crucial, if they went too fast or were too large, the cluster ended up disintegrating, a particle that is too large that goes too fast hits this cluster and obviously breaks it, but they discovered that the half-millimeter grains that traveled at 0.5 m per second constantly collided but became electrically charged and that caused them to end up attracting each other and This is how these groups were formed.
Electricity is very important for life to arise and apparently it is also very important for planets to emerge. If this process did not exist, the collapse of a cloud of gas and dust would have to be brutal, it would have to be an enormous concentration, keep in mind that this cloud that they have sent into space already has a very high concentration for what would be a real cloud of gas and dust in the cosmos.
! The truth will set us free and science is the one that is closest to the truth!
