Our planet could have been a Super Earth or not even existed

If we look at the Saturn’s rings, we see that they present a flattened shape Due to the centrifugal force exerted by the materials around it. The Sun, in the early days of the Solar System, also had rings around it. And this influences why the Earth is not bigger.

The earth is he largest rocky planet in the Solar System, but without becoming a super land. The calls “super lands» are terrestrial planets that orbit around the stars and that are larger than our planet, and that form around the 30% of exoplanets rocks that have been discovered so far.

Pressure zones, keys in the creation of the Earth

However, our planet did not reach such a large size due to small pressure areas in those early solar rings, as detailed in new research published in the Nature Astronomy. The team behind the research, including members from Rice University, the University of Bordeaux, the Southwest Research Institute in Boulder, Colo., and the Max Planck Institute for Astronomy in Heidelberg, ran hundreds of supercomputer simulations to recreate the formation. Of the solar system.

In it they found three high pressure bands in the early solar accretion disk, which may explain the composition of the asteroid belt between Mars and Jupiter and the formation of the kuiper belt beyond Neptune. They can also explain the nearly circular orbits of the four inner planets, their composition, and their various sizes.

Solar system

These high pressure areas can concentrate powder and act like planet factories as material accumulates. To simulate this, they used first dust, then planetesimals, and finally planets. According to their proposal, they claim that the pressure spikes produced deposits of material in the inner and outer zone of the solar system, and regulated the amount of material available for the planets to grow in the inner zone.

Earth might not have existed

If the disk had been uniform in its composition, the present solar system could have been very different from the present one, since the dust particles they would have gone to inner zone and they would have been lost in the Sun. Therefore, there had to be something for them to become planets.

At those high-pressure points, the gas is denser and gas particles move faster, helping to slow down heavier material like dust and rocks, helping them accumulate into planets.

The fact that we don’t live in a super earth is good, since a Super Earth with a size 10 times larger would have a grave 10 times larger. If you weigh 70 kg on Earth, on that planet you would weigh 700 kg, which would have considerably changed the type of life that formed on Earth. With such high gravity, a magnetic field may not have formed to protect us from ultraviolet radiation, and the solar winds would have destroyed any type of atmosphere, as is the case on Mars, for example.

With these conditions, the astronomers they have more information when it comes to identifying possible planets that can harbor life, since excessively large planets present problems such as the one we mentioned, of being able to maintain an atmosphere around them.

This Telegram feature allows you to store unlimited files online

Published

Highly appreciated by Internet users for the transfer of unlimited files, the Telegram application receives a new very practical service. Developers have used an end-to-end encrypted messaging app API to create an unlimited cloud storage service. Good news for people who want to keep documents and files for free.

A cloud storage service on Telegram

TeleDrive developers are innovating with a very interesting new service. They relied on the API available on Telegram to develop a free cloud storage system. You can then use it to store files much like on Google One or OneDrive. To use it, simply link your Telegram account and associate it with TeleDrive to start downloads.

However, note that this service has some limitations. In free mode, the user is limited to 1.5 GB bandwidth and daily 2 GB downloads. However, it is possible to remove this restriction by subscribing to a $10/year subscription with TeleDrive. You will be able to download large volumes of files no matter the time of day.

The peculiarities of Telegram’s cloud storage

Telegram is an end-to-end encrypted instant messaging application. In view of this, the files stored on TeleDrive are of a confidential nature. That said, note that it is possible to make them public and share it by message to your contacts on Telegram. You can generate a URL that anyone on the internet can easily access.

The use of this cloud storage service, however, poses a big concern. TeleDrive has not established any collaboration with the administration that governs the operation of Telegram. At any time, the latter could therefore decide to eliminate this service. It just needs to limit or break its API from its cloud storage. It is for this reason that specialists recommend using it as a secondary backup solution.

The Tesla Cybertruck electric pickup truck will have a “little brother” in miniature form

Published

on

While Elon Musk and Tesla continue to push back the start of production of the Cybertruck electric pickup truck to ever later dates, information has appeared on the network about the possible release of another version of this car.

The Tesla Cybertruck electric pickup truck will have a

Initially, the rather well-known Indian analyst Trip Chowdhry from Global Equities Research, who specializes, among other things, in Tesla, shared the information.

According to the source, Tesla will present two versions of the Cybertruck at a special event in March 2022.

Moreover, Chaudhry notes that both versions will receive “significant changes” compared to the Cybertruck originally shown. Chaudhry did not go into details of the changes, but noted that the second version of the Cybertruck will be about 15-20 percent smaller than the first. The bodies of both cars will reportedly be built by the same Texas-based Steel Dynamics company, which operates about 100 miles from Tesla’s Texas plant.

Chaudhry expects to hear the first official news on the matter on January 26, when Tesla will report earnings to investors.

Recall that in November 2019, Elon Musk himself said that in the long run it makes sense to add a more miniature Cybertruck to the lineup. Since then, however, he has not further developed the idea publicly.

WhatsApp will soon be able to draw with different strokes

The Meta (former Facebook) team of the popular WhatsApp messenger is working on a new interesting feature for users.

WhatsApp will soon be able to draw with different strokes

In the latest beta version of WhatsApp for Android, there are hints of new drawing tools. As the thematic resource WABetaInfo drew attention to, two new pencils have been added to the built-in WhatsApp image editor in addition to the existing pencil. The pencil icons indicate that the new pencils will allow you to draw thicker lines on images or videos.

WhatsApp will soon be able to draw with different strokes

WhatsApp currently allows you to change the color of the pencil, but there is no way to increase or decrease the thickness of the stroke. In addition, WhatsApp has begun work on a blur tool. This should make it easier to share screenshots and photos by allowing you to “blur” the areas you need before sending.

It is not yet clear when the new tools will become publicly available in the stable versions of WhatsApp.
