Hope this is not a redundant Q.
But this is ultimately a philosophical matter, a physical theory like relativity can't rule out the possibility that there is some metaphysical truth about simultaneity which has no empirical consequences, although relativity will make such a notion less appealing to anyone who favors razor[/url]Dmitry67 said:Yes, it is called a "Block Time", or Eternalism.

Relativity just says the laws of physics should be Lorentz-symmetric, it doesn't say they couldn't be stochastic (and I think physicists might still call a stochastic theory "classical" if it didn't have some of the other weird features of QM, like violations of Bell's theorem or the measurement problem).DaleSpam said:In all classical physics the future is completely and uniquely determined from the past. You have to be careful using phrases like "already exists" to describe the future, but in what sense would you say that the future does not "already exist" if it is completely and uniquely determined from the past? Remember, this is not about relativity, but about classical physics in general.
The theory of relativity was developed by Albert Einstein in the early 20th century and explains the relationship between space and time. It consists of two main theories: special relativity and general relativity. Special relativity deals with objects moving at a constant speed, while general relativity deals with the effects of gravity on space and time.
According to relativity, time is not absolute and can vary depending on the observer's frame of reference. This means that time can pass at different rates for two observers in different frames of reference. This is known as time dilation and has been confirmed through experiments and observations.
No, relativity does not support the idea of a predetermined future. According to relativity, the future is not set in stone and can change based on the actions and interactions of objects in the present. The theory allows for different possible outcomes to exist simultaneously.
Yes, according to the theory of relativity, time travel to the future is possible. This is because time passes at different rates for objects in different frames of reference. An object moving at a high speed will experience time passing slower than an object at rest, allowing it to travel into the future. However, traveling back in time is still a topic of debate and has not been proven to be possible.
Relativity has greatly influenced our understanding of the universe and our place in it. It has shown that space and time are interconnected and can be affected by gravity. It has also provided a better understanding of the behavior of objects at high speeds and in extreme conditions, such as near black holes. Relativity has also led to the development of technologies such as GPS, which rely on the principles of relativity for accurate time measurements.
