How stiff is space?

To produce enough warp to create an object like a black hole – with an extreme, maximal amount of space-time curvature – the universe has to concentrate mass and energy to an extraordinary degree. It turns out that space-time is very stiff, very resilient. But it can, and does, yield to stress.

Why is it called the fabric of space-time?

Any mass in a region of spacetime will lead to a distortion / curvature of space-time. Empty spacetime is flat, whereas spacetime in the presence of masses is curved due to gravity. Scientists treat spacetime as a smooth ‘fabric’ which is distorted by presence of mass. Thus the term the fabric of space and time.

What is space-time continuum for dummies?

Einstein’s theory of special relativity created a fundamental link between space and time. The universe can be viewed as having three space dimensions — up/down, left/right, forward/backward — and one time dimension. This 4-dimensional space is referred to as the space-time continuum.

Is space-time really a fabric?

Remember, it isn’t actually a fabric, but rather takes up the entirety of the Universe. 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. The larger a mass you put inside it, the more that spacetime gets curved.

What is the unified fabric of space and time stretch by?

Out was Newton’s idea, which had reigned for nearly two centuries, of masses that appeared to tug on one another. Instead, Einstein presented space and time as a unified fabric distorted by mass and energy.

How elastic is space time?

statement: the spacetime’s fabric is elastic. If we reduce the spacetime fabric to only one temporal dimension and only one spatial dimension (1, 1) then we have a surface which could be stress in the time dimension, implying a spatial compression.

Can space/time fabric be broken?

Yes, you can create and destroy space.

Is the space/time fabric elastic?

the spacetime’s fabric is elastic.

Does space have elasticity?

Space is having a characteristic feature of elasticity which acts upon each fragment of universe both horizontally as well as vertically in a perfect balance or equilibrium. Space acts as something like elastic membrane that helps in keeping the planets in respective orbits.

What is the difference between linear elasticity and hyperelastic elasticity?

Linear elasticity theory is thus the best known and most widely used branch of solid mechanics. Hyperelastic constitutive laws are used to model materials that respond elastically when subjected to very large strains. They account both for nonlinear material behavior and large shape changes.

What is the purpose of the discussion of elastic materials?

The discussion serves two purposes. Firstly, to illustrate how constitutive relations for solids are constructed; and secondly, to provide a short introduction to some of the methods that are used to solve solid mechanics problems. There are two general types of elastic material.

What are linear elastic constitutive relations?

Linear elastic constitutive relations model reversible behavior of a material that is subjected to small strains. Nearly all solid materials can be represented by linear elastic constitutive equations if they are subjected to sufficiently small stresses.

What is the effect of temperature on modulus of elasticity of polymer?

At the glass transition temperature, there is a dramatic drop in modulus. Above this temperature, there is a regime where the polymer shows `rubbery’ behavior the response is elastic; the stress does not depend strongly on strain rate or strain history, and the modulus increases with temperature.
