See this survey of Friedlander and Iwaniec for more on this “illusory” or “ghostly” parallel universe in analytic number theory that should not actually exist, but is surprisingly self-consistent and to date proven to be impossible to banish from the realm of possibility. The strategy of ...

The universe we observe is homogeneous on super-horizon scales, leading tothe ``cosmic homogeneity problem''. Inflation alleviates this problem butcannot solve it within the realm of conservative extrapolations of classicalphysics. A probabilistic solution of the problem is possible but is subject to...

Are they unique to Earth or could there be other environments, elsewhere in our Solar System or on exoplanets, for example? Organic molecules are present throughout the universe.它们是地球独有的吗,还是可能也存在于其他环境之中,比如在太阳系的其他地方或者系外行星上?有机分子遍布整个宇宙。But the...
This game of increasing the number of locations can't be played indefinitely. At a few hundred electrons the memory required to store the system exceeds the number of particles in the universe; thus there is no hope with conventional computers to ever simulate quantum dynamics....
Researchers think most of the cosmos is made up of matter and energy that cannot be "sensed" with our conventional instruments, leading to the names "dark matter" and "dark energy." It is thought that only 5% of the universe is made up of matter such as planets, stars and galaxies. ...
5.这是细节理解题。根据The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances.后来的人根据希腊的科学家的研究继续从事研究发现确实宇宙是有一些基本物质构成的,故选D。
