What is spacetime fabric made of?

The fabric of spacetime is made of density, pressure and flux of energy in all of its forms. Without energy there would be no spacetime.

Is the fabric of space stretching?

Things like galaxies are not anchored to space, so even if space stretched, galaxies could not care less. Their motion is determined by their initial velocity (things in this universe were “born” in a state of flying apart) and the laws of gravitational dynamics. No “stretching” involved.

Can you break the fabric of space time?

According to Einstein’s general relativity, it is impossible to tear the fabric of space. They performed a series of mathematical manipulations called flop transitions, which means that the original Calabi-Yau space is flopped over into a new configuration.

Can spacetime be stretched?

Spacetime can be stretched as much as you want. Indeed, at the singularity in a black hole the stretching becomes infinite, though I’d guess most of us think some quantum effects become important near the singularity and prevent it actually becoming infinite.

How does the fabric of spacetime work?

The fabric of the Universe, spacetime, is a tricky concept to understand. This fabric is continuous, smooth, and gets curved and deformed by the presence of matter and energy. Everything present within this spacetime moves along the path defined by that curvature, and its propagation is limited by the speed of light.

Is time a fabric?

In Einstein’s theory space and time is single entity called spacetime. We treat spacetime as a smooth fabric which is distorted by presence of energy. Thus the term the fabric of space and time. The term fabric is used to help us visualize how spacetime works in GR.

Is space really expanding?

Based on large quantities of experimental observation and theoretical work, the scientific consensus is that space itself is expanding, and that it expanded very rapidly within the first fraction of a second after the Big Bang. This kind of expansion is known as “metric expansion”.

Is spacetime actually a fabric?

Remember, it isn’t actually a fabric, but rather takes up the entirety of the Universe. Spacetime simply is: it’s what’s left over when we take everything in the Universe away that we’re capable of taking away.

What is spacetime and how does it work?

Spacetime simply is: it’s what’s left over when we take everything in the Universe away that we’re capable of taking away. When we put things like masses down in the Universe, spacetime is still there, too, but its properties are altered by whatever it is that’s inside it.

Why is the fabric of space curved?

It appears to depict the fabric of space as being curved by the presence of mass, and therefore, any other particle traveling along this fabric will have its path bent towards this gravitational source. The larger the mass and the closer you get to it, the larger the curvature, and therefore, the larger the bending.

What determines the curvature of spacetime?

The spacetime curvature around any massive object is determined by the combination of mass and distance from the center-of-mass. However, this two-dimensional grid-like depiction of spacetime isn’t necessarily the most accurate way to perceive it. (T. PYLE/CALTECH/MIT/LIGO LAB)
