If life existed on Venus, what would life forms look like? This is not a ridiculous idea (below)
1. Venus may be like Bespin in Star Wars, but for microbes. One of the latest hypotheses about potential life on Venus is that it may have evolved to live in Earth's clouds. Part of the reason for this theory is that scientists believe that the large amounts of ammonia detected on Earth are likely of biological origin. What's more, such life forms are likely to be something similar to bacteria. The rationale is that, given what we currently know about Venus' chemistry, ammonia should not really be present on Venus, at least in the quantities detected, and its presence can only be explained by the presence of certain biological processes.

Strange photos were taken on Venus, and moving objects appeared on the surface, causing a sensation in the scientific community
The eight planets in the solar system have unique appearances and different sizes. Although the earth is not the largest, it is the most special one, because the surface of this planet has both land and ocean, and there are many green areas on the land. , a feature not found on other planets. Once upon a time, Venus was considered Earth's sister planet because the two were similar in many ways. For example, the mass of Venus is 0.82 times that of Earth, its radius is 0.95 times that of Earth, and its gravity is 0.9 times that of Earth.

Know better than you what looks can attract your AI
Appearance preferences may change over time (such as having a mustache or wearing a monocle), but in any case, top social status can not only attract a significant other, it may even help you get promoted, or make it easier to meet powerful elites. Despite the multifaceted social impact of "look", the mechanisms behind these preferences remain unfathomable. Rarely do we make a "conscious and logical judgment" about a person's appearance first, and often guess the cause after experiencing the feeling, but artificial intelligence may be able to help solve this problem.

From the almost "car accident" of Starlink satellites, do Internet satellites really only have advantages?
I believe that many friends in front of the screen are no longer familiar with Musk. As the founder of SpaceX, Tesla and Neuralink, he can be called a generation of Internet leaders. On the 19th, the SpaceX starship prototype SN15 was tested in Texas, USA. The live broadcast showed that SN15 flew to an altitude of 10 kilometers and successfully landed at the Texas base 6 minutes after takeoff. It has successfully sent humans to space, completed another commercial manned flight, and plans to send humans to Mars in 2025.
