Distance time travels per second

[Pricey]

If at the big bang, space and time began, would time not travel at a certain rate? Such as, light travels at 299792458m/sec. The solar system has been here for some 5 billion years and we are looking into outerspace at light that has taken 5 billion years to reach us. Would that not mean that time has reached here twice as quickly (if not more)? would that then mean that time is the fastest that anything can travel, and that light speed can be breeched?

space and time are intimately tied together by the spacetime metric which is analogous to the pythagorean theorem and so Physicists don't talk about space and time as being separate but as an entity spacetime. The expansion of the universe in theory is the expansion of spacetime. It is not dictated by limits like the speed of light but particles traveling within spacetime are.

Time does not travel anywhere. Time is what a clock measures. A clock is an instrument with three basic parts: an oscillator, a counter, and a display. In the macroscopic world time has a direction which is forward, it continues forward at 1 sec/sec. Time is a measure of the "distance" between events.

Space and time are not "things" that move around and interact, they are the framework or background by which we are able to label systems of objects and how they move and interact. As such neither space nor time can move, attain velocities, accelerate, etc. All these happen to objects within spacetime such as an electron or proton.

I must clarify that time itself does not travel. Time is a fundamental dimension in which events occur and it is often measured in units such as seconds, minutes, or years. It is not something that can be traveled or breached.

In terms of the expansion of the universe, the concept of time is closely related to the concept of space. As the universe expands, space itself is expanding, which also affects the perception of time. This is known as the cosmological redshift, where light from distant objects appears to be shifted towards longer wavelengths, indicating that the universe is expanding.

In the context of the Big Bang, it is important to note that the initial expansion of the universe was not a movement through space but rather an expansion of space itself. At this point, the concept of time becomes difficult to define as it is closely intertwined with the expansion of space.

Regarding the speed of light, it is currently considered to be the fastest possible speed in the universe. This is based on the theory of relativity, which states that the speed of light is a constant and cannot be exceeded. So while it may seem that light from distant objects has reached us twice as quickly, this is due to the expansion of space rather than a change in the speed of light.

In conclusion, the concept of time is complex and is closely linked to the expansion of the universe. While the speed of light may seem to have reached us twice as quickly, this is a result of the expansion of space rather than a change in the speed of light. The theory of relativity still holds that the speed of light is the fastest possible speed in the universe.
