yes, they are part of the same thingWe know that time and space are intertwined
No, we don't "know" that, since it's not true as regards the event horizon of a black hole. What is true is that observations from far away from an event horizon show an appearance of time slowing down but we know that the time for the object AT the event horizon is not affected at all by the event horizon (which isn't even a physical thing, just a coordinate)., and that time is relative depending on mass, such as near an event horizon.
There is no reason to believe so.Does the absence of any mass, out in the voids of space, between galaxies, also affect time's consistancy?
Not clear what this even means. Light travels at c in a vacuum regardless of any nearby mass but the amount of time it can take to get from point A to point B can depend on the path that it takes through space-time so the light in an Einstein Ring, for example, will have taken longer to get to us than it would have had there been no intervening mass that "bent" the light back towards us and the light had just come directly towards us.If not, would light pass though these areas at a different rate comparatively?

Time, mass, and space are interconnected concepts in physics. Time is a measure of the duration of events, while mass is a measure of the amount of matter in an object. Space is the three-dimensional extent in which objects and events exist. According to Einstein's theory of relativity, time and space are not absolute, but rather are relative to the observer's frame of reference. This means that the measurement of time, mass, and space can vary depending on the observer's perspective.
Time is measured using various units, such as seconds, minutes, hours, and years. These units are based on the movement of celestial bodies, such as the Earth's rotation around its axis and its orbit around the sun. While the measurement of time may vary depending on the observer's frame of reference, it remains consistent within a specific frame of reference. However, time can be affected by factors such as gravity and velocity, leading to phenomena like time dilation.
According to Einstein's theory of relativity, mass does affect the passage of time. This phenomenon is known as gravitational time dilation. The more massive an object is, the stronger its gravitational pull, which can cause time to pass slower for objects closer to it. For example, time passes slightly slower for objects on Earth's surface compared to objects in orbit around the Earth.
The concept of time travel is a popular topic in science fiction, but in reality, it is still a theoretical concept. According to Einstein's theory of relativity, time travel may be possible through the use of wormholes or traveling at speeds close to the speed of light. However, it requires an immense amount of energy and is currently beyond our technological capabilities.
The concept of space-time, which combines the dimensions of space and time, has greatly influenced our understanding of the universe. It has helped explain phenomena such as the bending of light around massive objects and the expansion of the universe. It also forms the basis for theories like the Big Bang and the concept of a multiverse. By understanding the relationship between time, mass, and space, we can gain a deeper understanding of the universe and our place in it.
