R.The secret of forming planets in regular static electricity may be the same phenomenon that can make your hair stand on the end or give you an electric shock after walking across the carpet.
A new study, published in Nature astronomyIt indicates that static electricity allows small dust molecules in Protoplainis tablets – roller dishes for gas and dust formed around young stars – to assemble together in “gravel” that are large enough to play a role in the formation of planets.
The image above shows basalt beads, an area of 0.55 mm, which was used in an experiment, which occurred on a missile under the pelvis.
Results help in solving something that is called something called the high barrier-the sized threshold that particles must reach in order to rely on gravity to join other particles-Says Lead Counter of the Study Jens Teaseer, an astronomical physicist at Duisburg-Assen University in Germany.

Dust particles need fixed electricity to make them “sticky” enough to gather in gravel that can form planets.
Only when the molecules grow larger than this threshold size – a quarter of an inch, depending on the circumstances – they can eventually join the formation of the rock “Planetsimals”, from about half a mile to 100 miles across, which scientists believe and then collide within the protoplantis tablets to create planets like Earth.
“Do not adhere to the smaller dust particles together,” says Teiser, unless they had an electrostatic charge.
Fixed electricity is produced when different objects communicate with a defect in positive and negative charges, leading to electrostatic charge. In this case, the electrostatic charge is generated by collision between small dust particles, which can cause them to either earn electrons or electrons, which leads to negative or positive charge, respectively. Tayzer says that the charged particles will attract each other – that gather to the electrostatic law – and can gather together to create larger molecules.

Teiser and its colleagues are suspected that this is the case after conducting “dropping the tower” experiments with small basalt particles, where they noticed the behavior of these particles within nine seconds of weight. But this was not enough time to reach a conclusion, so in 2022, the researchers tried a missile under the episodes that were launched from Kiruna in northern Sweden, to monitor how particles acted within six minutes of weightlessness.
During the launch of the year 2022, described in the latest study, the missile reached a height of about 160 miles, and lack of weight began at a time when the missile load fell to the ground. At this point, the particle tank was opened on board the ship, with the firing of the molecules. In some cases, the tank was shaken to give the electronic charge particles, but in other cases, it was not. Only those particles that were shook began to gather in a total. It was the largest collection, as shown in the picture, a little more than inch. Teiser says that his team of researchers sent four versions of their high experience in the missile, each with different start conditions.
Researchers believe that their findings indicate that dust molecules in protoplantic tablets need fixed electricity to make them “sticky” enough to gather in gravel that can form planets. They were also able to calculate the maximum speeds that small molecules could travel when they collide if they wanted to create blocks: about and a half feet per second. Clash at larger speeds tend to wear large groups surfaces.
Results will be used in models trying to explain how huge planets arise from us from just dust.
