## Can space/time exist without matter?

No. General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field. …

## How does matter bend space-time?

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.

**Why does matter affect spacetime?**

Originally Answered: Why does a mass curve space-time? Matter (not mass) curves the space-time because – experimentally verified and mathematically natural – Einstein’s equations that govern the space-time curvature say that the local-curvature-encoding Einstein tensor Gμν is proportional to the stress-energy Tμν.

**What is time space and matter?**

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. It is an extension of Einstein’s special theory of relativity – but such a massive one that it took him 10 years, from 1905 to 1915, to get from one to the other.

### Is space/time made of matter?

A little more than 100 years ago most people–and most scientists–thought of matter as continuous. A theory with the strange name of loop quantum gravity predicts that space and time are indeed made of discrete pieces. …

### Is space and time one thing?

Thus, space and time are effectively interchangeable, and fundamentally the same thing (or at least two different sides of the same coin), an effect which becomes much more noticeable at relativistic speeds approaching the speed of light.

**Does time create gravity?**

Yes. Time causes gravity. Gravity is not a force, it is an effect of spacetime curvature.

**What is the difference between space and matter?**

Matter is real stuff with mass. Space is the volume in which it exists.

## What does it mean by space and time?

You are confused. When your husband says he needs space, you don’t jump to the conclusion that he wants to divorce you. It may possibly be other meaning. He could be feeling confused and perhaps giving him space and time will be better. Rather than wailing and begging him not to do so, just give him exactly what he needs.

## What is the exact meaning of time and space?

space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein ’s special theory of relativity (1905). Common intuition previously supposed no connection between space and time.

**What is the relation between space and time?**

– When i = N, it will run N times. – When i = N / 2, it will run N / 2 times. – When i = N / 4, it will run N / 4 times. – And so on.

**What is more important space or time?**

Time is always much greater than space. Space hardens processes, whereas time propels towards the future and encourages us to go forward in hope.”. For Pope Francis, time is greater than space
