宋圭武 宇宙可能存在一个时间和空间都为负的世界
一个可能的推测是：宇宙可能是弱对称存在的。人是一个小宇宙，人是弱对称存在的。宇宙也可能是弱对称存在的。在弱对称的宇宙里，存在一个时间为正的世界，也存在一个时间为负的世界；存在一个空间为正的空间，也存在一个空间为负的空间。其中量子可能运行在弱对称宇宙的边界。
从时间看，宇宙可能由两个世界构成，一个世界时间为正值，一个世界时间为负值。在时间为正值的世界，物体的运动速度小于光速。在时间为负值的世界，对时间为正值的世界里的人而言，物体的运动速度是大于光速的。但对于在时间为负值世界里的人而言，其本身所在世界的时间又为正值，而不是负值，同时，对于时间为负值的世界里的人而言，其所在世界的物体的运动速度又小于光速。但在时间为负值所在世界里的人，看时间为正值的世界，对其而言，时间又是负值，且物体的运动速度又大于光速。这里两个世界几乎是以对称的方式存在的。
在两个世界的边界，物体的运动速度等于光速。根据相对论，物体运动速度越快，越接近光速，时间越慢，质量越大。所以，在两个世界的边界，时间静止，而边界物质的质量为无限大。黑洞可能是两个世界的边界点或接近两个世界的边界。
在时间为负值的世界，对时间为正值的世界里的人而言，其物质的存在形态必然是暗物质，其能量形态必然是暗能量。因为在时间为负值的世界，对时间为正值的世界里的人而言，物体的运动速度超过光速，所以，人类在光速以内时间为正值的世界必然是看不到感觉不到时间为负值世界的一切存在的，这个世界对人类而言，其存在必然是以暗的形态存在。
这里假如当一个人从时间为正的世界进入到时间为负值的世界，在时间为负值的世界，对这个人而言，时间又变成了正值，而他原来的世界，时间又变成了负值。也就是对人类而言，时间为正值的世界与时间为负值的世界是对称存在的，但这种对称可能是一种弱对称，而且这两个世界本质是连通的，且是持续连通循环和互相转化的。
量子纠缠是由于两个量子分别运动在不同的时间世界，而两个世界的时间的正负值互相抵消，所以，量子纠缠必然是同时发生，中间没有时间。问题是，另一个量子为什么不是暗物质？这里也许是两个量子同时呈现的时间都在时间为正值的世界，但运动的轨迹是在两个不同的世界。这样，产生纠缠的两个量子，对人类而言，都不是暗物质，且几乎是同时出现。
人类的认识达到量子层面，说明科学研究已经快接近两个世界的边界，但要真正到达这个边界并真正认识这个边界规律，又是不可能的，但人类可以无限接近边界并在认识层面也可以无限接近边界的规律。
Song Guiwu The universe may have a world with negative time and space
A possible speculation is that the universe may be a weakly symmetric existence.Human beings are a small universe, and human beings are weakly symmetric existence.The universe may also be a weakly symmetric existence.In the weakly symmetric universe, there is a world with positive time and a world with negative time;there is a space with positive space and a space with negative space.Quantum may run at the boundary of the weakly symmetric universe.From the perspective of time, the universe may consist of two worlds, one world with positive time and one world with negative time.In the world with positive time, the speed of objects is less than the speed of light.In the world with negative time, the speed of objects is greater than the speed of light for the people in the world with positive time.But for the people in the world with negative time, the time of their own world is positive, not negative. At the same time, for the people in the world with negative time, the speed of objects in their world is less than the speed of light.But for the people in the world with negative time, when they look at the world with positive time, for them, time is negative, and the speed of objects is greater than the speed of light.Here the two worlds almost exist in a symmetric way. At the boundary of two worlds, the speed of objects is equal to the speed of light.According to the theory of relativity, the faster the speed of objects, the closer to the speed of light, the slower the time, the greater the mass.Therefore, at the boundary of two worlds, time is still, while the mass of the boundary material is infinite.Black holes may be the boundary points or close to the boundary of two worlds. In the world with negative time, for the people in the world with positive time, the existence form of its matter is bound to be dark matter, and its energy form is bound to be dark energy.Because in the world with negative time, for the people in the world with positive time, the speed of objects exceeds the speed of light, so human beings in the world with positive time within the speed of light must not see or feel all the existence of the world with negative time. This world, for human beings, must exist in the form of dark. Here if a person from the world with positive time enters the world with negative time, in the world with negative time, for this person, time becomes positive again, while his original world, time becomes negative again. That is to say, for human beings, the positive value of time and the negative value of time are symmetrical, but this symmetry may be a weak symmetry, and the two worlds are connected in nature, and are continuously connected and transformed into each other. Quantum entanglement is due to the fact that two quanta move in different time worlds, and the positive and negative values of the time in the two worlds cancel each other out, so quantum entanglement must occur simultaneously, without time in between.The question is, why is the other quantum not dark matter?Maybe the two quanta are simultaneously presented in the positive value of time, but the trajectory of motion is in two different worlds.In this way, the two quanta that produce entanglement are not dark matter for human beings, and almost appear simultaneously.Human cognition has reached the quantum level, indicating that scientific research has been close to the boundary of the two worlds. But it is impossible to really reach the boundary and really understand the boundary law. But human beings can be infinitely close to the boundary and can also be infinitely close to the boundary law at the level of cognition.
