Time travel? Humans cannot go back to the past because paradoxes will occur
Einstein was an outstanding biologist, he put forward many unfathomable basic theories, such as quantum theory, photon quantum hypothesis, photoelectric effect, etc. He also has many achievements in the nuclear industry, naturally, most famously or quantum theory. Until now, it has still become a classic basic theoretical theory. Many people feel that Einstein's brain development level is the greatest, so he can come up with this outstanding basic theory.

How much energy can a kilogram of uranium 235 produce after fission? How long can it be used by humans
Since the advent of human beings, to maintain basic life activities cannot do without the support of energy. In the beginning, everyone used fire to give themselves energy. In modern times, based on the continuous scientific research of some chemical substances, everyone found that nuclear fission and fusion can produce great energy, and experts discovered that nuclear power generation is also based on this. The technology of controllable nuclear fission has been developed.

What is Vertical Farming?
Vertical farming: Why stacking crops high could be the future of agriculture Vertical farming is the practice of growing crops in vertically stacked layers.It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. Some common choices of structures to house vertical farming systems include buildings, shipping containers, tunnels, and abandoned mine shafts. As of 2020, there is the equivalent of about 30 ha (74 acres) of operational vertical farmland in the world.
