Is time irrelevant in quantum mechanics?

In summary, according to the principles of quantum mechanics, time is considered to be irrelevant and is often treated as an external parameter rather than an intrinsic aspect of the system. This is due to the fact that quantum mechanics operates on the scale of the very small, where the concept of time as a continuous and linear progression breaks down. Instead, quantum mechanics relies on probabilistic outcomes and the concept of "superposition," where particles can exist in multiple states simultaneously. This unique perspective on time challenges our traditional understanding of the universe and has implications for theories of time and causality.

TL;DR Summary
The theory of loop quantum gravity seems to show that time does not exist and can disappear from the equations
Could one come to think that time is irrelevant in quantum mechanics? we know that the QM equations are written with the time variable, (schrodinger equation). Yet everything suggests that time is irrelevant, as the search for loop quantum gravity seems to indicate

Everything ? You only mentioned LQG. It hardly jusifies throwing away all other physics.

Where did you read this?

"The theory seems to show that..." is not an acceptable reference.
This thread is closed until the original poster can send me or any of the other mentors a link to an appropriate peer-reviewed paper describing the equations he's talking about and how they imply that "time does not exist".

1. What is the concept of time in quantum mechanics?

In quantum mechanics, time is considered to be an independent variable that is separate from space. It is used as a parameter to describe the evolution of a quantum system, but it is not considered to be a fundamental aspect of the theory.

2. Does time behave differently in quantum mechanics compared to classical mechanics?

Yes, time behaves differently in quantum mechanics compared to classical mechanics. In classical mechanics, time is considered to be absolute and universal, while in quantum mechanics, it is relative and dependent on the observer's frame of reference.

3. Can time travel be possible in quantum mechanics?

There are theories in quantum mechanics that suggest the possibility of time travel, but it is still a highly debated topic and has not been proven to be possible. The concept of time in quantum mechanics is still not fully understood, and more research is needed to fully explore the potential of time travel in this field.

4. How does the concept of time affect the uncertainty principle in quantum mechanics?

The uncertainty principle in quantum mechanics states that it is impossible to know both the position and momentum of a particle with absolute certainty. The concept of time plays a role in this principle as it is used to describe the evolution of a particle over time. The more precisely we know the position of a particle, the less we know about its momentum and vice versa.

5. Can we ignore the concept of time in quantum mechanics?

No, we cannot ignore the concept of time in quantum mechanics. While it may not be a fundamental aspect of the theory, it is still an important parameter used to describe the behavior of quantum systems. Ignoring time would lead to incomplete and inaccurate descriptions of quantum phenomena.
