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.

Three Observation Dimensions to Unravel the Mystery of Sanxingdui
Since the excavation of the six newly discovered "sacrificial pits" in Sanxingdui, the world's attention to the bronze civilization of Sanxingdui has become hot again, and various speculations and explanations are even more dazzling. The reason why people feel mysterious about Sanxingdui is because we used to be too accustomed to observe it with traditional eyes and ways of thinking, and use our known "knowledge map" to compare this unknown world. So far, the archaeological excavations of these six pits in Sanxingdui are still in progress, and we do not know how many new things and new phenomena will continue to emerge, which will make people shocked or even more confused. For example, everyone is looking forward to the discovery of text in the subsequent Sanxingdui archaeology, so as to solve the mystery of Sanxingdui in one fell swoop. In fact, this is still guided by traditional concepts: all highly developed civilizations should have written characters. Yin and Shang had such characters as oracle bone inscriptions and bronze inscriptions, but why did Sanxingdui not have them? If no text is found, does the distinctive Sanxingdui civilization still belong to the Chinese civilization system? Therefore, what kind of vision to observe Sanxingdui, to look at the various archaeological relics and relics that have been unearthed and about to be unearthed, so as to lead the scientific road to uncover the mystery of Sanxingdui, is very important at present.

It’s not enough to drive this spaceship directly through it. You must know that the air on the earth can’t be seen or touched. We can come and go freely in the air and do all kinds of free activities. And Jupiter is a gas planet, that's true, but it's impossible for us to pass through Jupiter as we pass through air, why would I say that?
