Feitian computing power

Man has been racing against the dead line

er, dead line, no problem

throw a few bricks:

if nuclear energy is not done before fossil energy is exhausted (solar energy is also nuclear energy, no problem), it is not only the problem of civilization retrogression, but also locked up. Because we can't organize higher scale instrialization, we can't further test our scientific theory. Scientists guess that it's much more fierce than civil science


another question about scientists' guessing: the verification of scientific theories is becoming more and more difficult. 300 years ago, people put forward theoretical explanations based on phenomena. 200 years ago, people put forward theories while doing experimental verification. 100 years ago, people expected to have enough ability to verify (such as gravitational waves) in 100 years. Now? For example, in string theory, when can we reach the required energy level to test this theory

before space migration, there was an upper limit of computing power that human beings could master. This upper limit was determined by factors such as electric power and mineral reserves (such as rare earth needed for all semiconctors and quantum computers in the future). Will it be the computing power needed for a key problem of space migration, Is it beyond human control

the smaller the ecosystem is, the easier it is to collapse, and the larger the ecosystem is, the more stable it is, but that doesn't mean it won't collapse. In the long run, the earth's ecosystem will collapse sooner or later. Are humans ready
another problem is that the more knowledge human beings accumulate, the longer an indivial needs to learn and reach the theoretical frontier. Will it take a person 80 years to get to the forefront of a subject one day, and how many years will he have left to do research? Some knowledge can be compressed, only remember the conclusion, some not, you must understand him, push him down, spend time to master him

if we can't escape from the earth before the sun turns into a red giant, we will be eaten by the sun, and human beings will be on the street collectively. Of course, we have five billion years, and this problem is more distant than the previous ones

in the first half of the 21st century, we are still in the stage of great strides forward
but your worry is right, and no one can guarantee what will happen in the future
