Are space and energy the same thing?

Space mass and energy are not same thing. But mass can be defined in terms of energy. Space is the emptyness between two objects.

Does spacetime flow?

Now researchers suggest that if spacetime is a fluid, it must be an extraordinary kind of fluid known as a superfluid. These findings could help test models of quantum gravity. A superfluid is a fluid that flows with virtually zero friction or viscosity. In comparison, water might seem as slow as molasses.

Why does energy affect spacetime?

Since matter carries energy (via Einstein’s famous relation that energy is mass times the speed of light squared), such objects will have a gravitational field and so they will distort space-time. Because an electromagnetic field contains energy, momentum, and so on, it will produce a gravitational field of its own.

What is relationship between matter and energy?

How are matter and energy related? Matter is the stuff that everything is made of (see: Matter). Energy is a property that matter has. The same amount matter can have different amounts of energy and so represent different states of matter.

How does space expand?

The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. As the spatial part of the universe’s spacetime metric increases in scale, objects become more distant from one another at ever-increasing speeds.

Why is the spacetime curved?

When a smaller mass passes near a larger mass, it curves toward the larger mass because spacetime itself is curved toward the larger mass. The smaller mass is not “attracted” to the larger mass by any force. The smaller mass simply follows the structure of curved spacetime near the larger mass.

Does dark energy curve spacetime?

Dark energy as a curvature of space-time induced by quantum vacuum fluctuations. It is shown that quantum vacuum fluctuations give rise to a curvature of space-time of the order appropriate to explain the observed accelerated expansion of the universe.

What is the fundamental reason for merging space and time?

The fundamental reason for merging space and time into spacetime is that space and time are separately not invariant, which is to say that, under the proper conditions, different observers will disagree on the length of time between two events (because of time dilation) or the distance between the two events…

Are matter energy space and time all forms of one thing?

That makes Matter = Energy; Energy = Space; Space = Time. Therefore matter, energy, space and time are all interchangeable characteristics, which implies strongly that they are all forms of one thing.

What is the relationship between matter and space?

As soon as one object begins to move relative to another object then time suddenly comes into play, matter suddenly appears to exist, and space is now measurable as the distance between two objects as measured by a third observer object. The common denominator here is movement, specifically relative movement.

What is the spacetime interval between two events in space?

In other words, the spacetime interval between two events on the world line of something moving at the speed of light is zero. Such an interval is termed lightlike or null. A photon arriving in our eye from a distant star will not have aged, despite having (from our perspective) spent years in its passage.
