Hell ants from the Cretaceous period, found in amber, about 99 million years ago
Not long ago, when a scientist was studying amber fossils, they found an ant that was hunting in an amber. This ant is not small. It is an extinct ancient species. Its name is "Hell Ant". It has a time of about 99 million years, but it is not the ancestor of modern ants. The animal it was preying at that time was probably the ancestor of the current cockroach. At this moment, it happened to be wrapped in resin, forming a precious fossil.

Which species will be inscribed on the last gravestone in the world's extinct animal cemetery?
Throughout the history of the development of the universe, we find that the extinction of a species is not a rare event. In the long history of the past 450 million years, the earth has experienced five historical periods in which the species and number of organisms have declined sharply. These events are called "five mass extinctions". The most famous is the fifth extinction, 96% of marine life and 75% of land life suffered mass extinction, including the dinosaurs that dominated the world for 140 million years. Due to the extinction of dinosaurs, mammals also began to multiply, and primitive humans began to multiply.

When will the 10-meter-diameter super-large space station manned capsule be launched?
The basic dimensions of the core module of the space station that have successfully entered orbit are: a total length of 16.6 meters, a maximum diameter of 4.2 meters, and a total weight of 22.5 tons. The interior can provide more than 50 cubic meters of living and working space for astronauts who enter it in the future, which has been greatly improved compared with the two Tiangong series space stations launched in the past. It is basically a direct upgrade from a single room to a three-bedroom level. After the successful launch and docking of the future No. 1 and No. 2 large-scale experimental modules, the astronauts' perennial casual activity space will be further expanded from 50 cubic meters in the early stage to 110 to 180 cubic meters. It is equivalent to upgrading from a three-bedroom to a small villa again, which can basically be said to exceed the maximum activity space inside the Mir space station launched by the former Soviet Union. In fact, in terms of the size and weight of a single main core cabin, the 22.5-ton class is already the largest in the world. Because neither the current core module of the Star of the International Space Station nor the command module of the Mir that year has exceeded the maximum level of 22 tons. The current extra 0.5 tons.

Why do organisms generally grow larger in an oxygen-rich environment?
The day before yesterday, Hanhai Langshan (Hun Langshan) mentioned that the earth's current atmospheric oxygen content is only 21%, but this is not the era with the highest atmospheric oxygen content in the earth's geological history. The era of the highest oxygen content in Earth's geological history is thought to account for 27% to 28% of the atmospheric content, which is more than 30% of the oxygen content at sea level today. It is thought that there may be two such peaks of oxygen enrichment. One appeared in the Carboniferous period between 360 million and 300 million years ago. Plants at this time grow very large because of the rich oxygen. Ferns are often tens of meters to hundreds of meters high. After the death of these giant plants, a large amount of accumulation was generated, which is the largest source of coal formations today, so this era is called the Carboniferous. Another peak of oxygen enrichment may have appeared in the Jurassic period 200 million to 140 million years ago, when the world was full of giant reptiles, becoming the most prosperous era of dinosaurs. Therefore, once the earth is enriched with oxygen, the size of both plants and animals will increase simultaneously on a large scale. This is already the basic consensus. But the problem is,

Volcanoes are natural incinerators. Can we use volcanoes to burn garbage?
Volcanoes are one of the most unforgiving natural phenomena on Earth. If you fall into the center filled with magma, the body will quickly blister and disappear without a trace. Then someone will say, since volcanoes are so good at processing things, why don't we use this natural "incinerator" to process our garbage? It's easier said than done, but it's not that simple...
