The Road to Cosmic Civilization

The average level of physics at Qidian is simply unbearable, and there are many misunderstandings. I write this article in detail. First of all, we are all earthlings and speak in earthly terms, so physics terms should use human definitions of them instead of tampering with them at will. First of all, it must be clear that energy is an attribute of matter, not the matter itself, so the word "pure energy" itself is wrong. In the speech of people on earth, "pure" and "energy" cannot be put together. For example, height and weight are attributes of a person, which are invisible and intangible. People do not have "height weapons" and "weight shields". A string of numbers or a physical quantity cannot have an effect on matter. So, what is energy? To put it simply, energy is a physical quantity used to measure the ability of matter to perform work on the outside. Energy can take many forms depending on how work is done, but the unit is always the joule. Let me give you another example: a gun fires a bullet that carries kinetic energy, killing an enemy. In this process, the bullet kills the enemy, not the kinetic energy. The kinetic energy represents the lethality of the bullet, nothing more. About energy weapons. In fact, every human weapon can be said to be an "energy weapon". The so-called destruction is essentially changing the state of motion of matter. How to change? Use substances with extremely high energy and strong external ability to make changes. In fact, the vast majority of Qidian readers and authors have confused energy and matter, and even invented words such as "energy density" and "energy concentration". But this is all nonsense, a string of numbers with units, an abstract concept, a "thing" that cannot be directly observed in reality, how can it be called "concentration" and "density"? It's totally wrong. If you want to write a science fiction novel, the "science" part must be more important than the "fantasy". The "energy" in starting point science fiction is not energy at all (at least it does not meet the definition of energy by people on earth), but a special substance. Perhaps some people will say: "Humans do not fully understand the universe, everything is possible!" I can only say that the word "energy" has been used before. For the thing in your mind that is completely different in nature from "energy", you should specifically think of a new physics term for it, instead of stealing the name of "energy" and misleading people. Finally, China's popular science education has a long way to go. I hope everyone can recharge their brains and increase their knowledge. I also hope that the author's books will get better and better, and not fall in line with those "science fiction" books that started out there.

The half-life of tritium is very short, only 12.43 Years. There is almost no tritium in nature and can only be produced artificially.

Very good, my favorite interstellar style novel

The author's writing style needs to be improved, but the plot is still readable. I will take the time to advertise for you in the review sections of several well-known hard science fiction books, but I will have to wait until the content is rich enough. Another point to note, the author, you use too many periods. Compared with exclamation points, you use too few question marks and ellipses. This can easily give people the feeling of writing a running account. I hope you can improve it.

You see, the hegemon of the universe is just too yyy, and the data is written randomly. It is just a running account, and it cannot be bad even if it is bad. People have good grades

Introduction We still need a material that can withstand the friction temperature caused by speeding, otherwise, going faster than light would be suicide...

It turns out it's updated every two days, and the newcomers thought they were eunuchs.

I found that it was much better to read later. I have made great progress. I suggest you go to Earth Era to promote it. It is an old brand and very popular.

Up master, is it okay for you to blatantly take photos like this? It goes against my values, Guo Jia. It's best not to follow the same old routine of giving lunch to someone, otherwise I will disown him (´-ω-`)(ಡωಡ)

It feels pretty good, why is there no one there?
