Is space/time affected by mass?

Large objects such as the Sun and planets aren’t the only masses that warp the fabric of space-time. Anything with mass—including your body—bends this four-dimensional cosmic grid. The strength of gravity depends on the size of the space-time warp.

How is mass related to space-time?

There is a fixed mass relation between space-time, in other words, mass is a property of space-time continuum for a static universe, but for an active universe (Section 4) mass should be a dimension of universe.

What determines the space/time curvature of the universe?

Earth wouldn’t immediately fly off in a straight line; it continue orbiting the Sun’s location for another 8 minutes and 20 seconds. It isn’t mass that determines gravitation, but rather the curvature of space, which is determined by the sum of all the matter and energy in it.

How does the mass of the object affect space-time?

Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

What is meant by space time curvature?

The curvature of spacetime influences the motion of massive bodies within it; in turn, as massive bodies move in spacetime, the curvature changes and the geometry of spacetime is in constant evolution. Gravity then provides a description of the dynamic interaction between matter and spacetime.

How does space affect time?

Time dilation goes back to Einstein’s theory of special relativity, which teaches us that motion through space actually creates alterations in the flow of time. The clock in motion will tick more slowly than the clocks we’re watching on Earth.

What is space-time and why does it matter?

According to the best of current physical theories, space-time explains the unusual relativistic effects that arise from traveling near the speed of light as well as the motion of massive objects in the universe.

What is the edge of space-time in the universe?

In either the open or closed universe, the only “edge” to space-time occurs at the Big Bang (and perhaps its counterpart the Big Crunch), so it is not logically necessary (or sensible) to consider this question. It is beyond the realm of the Big Bang Model to say what gave rise to the Big Bang.

How does mass affect spacetime?

We are taught that mass warps spacetime, and the curvature of spacetime around mass explains gravity — so that an object in orbit around Earth, for example, is actually going in a straight line through curved spacetime. Ok, that makes sense, but when mass (like the Earth) moves through spacetime and bends it, why does spacetime not stay bent?

Does the Big Bang model describe space-time?

The Big Bang Model does not attempt to describe that region of space significantly beyond our horizon – space-time could well be quite different out there. It is possible that the universe has a more complicated global topology than that which is portrayed here, while still having the same local curvature.
