Separate dimensions refer to different planes of existence or alternate realities that exist parallel to our own. It is theorized that there are multiple dimensions beyond the three-dimensional world we can perceive.
The concept of two objects traveling in separate dimensions is purely theoretical and has not been proven. However, it is believed that if an object has the ability to move between dimensions, it could potentially travel alongside another object that also has this capability.
Again, this is purely theoretical. It is believed that if two objects were to travel in separate dimensions, they would exist in different planes of existence and therefore would not be able to interact with each other. However, some theories suggest that there may be ways to communicate or influence other dimensions.
As of now, we do not have the technology or means to observe or detect objects traveling in separate dimensions. Our current understanding of physics and the laws of our universe do not support the existence of other dimensions, so it is difficult to measure or prove their existence.
The concept of separate dimensions challenges our current understanding of the universe and raises questions about the nature of reality. It opens up possibilities for alternate realities and parallel universes, and could potentially change the way we view our own existence and place in the universe.
