What is the relationship between space-time and matter?

What is the relationship between space-time 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”.

What is the theory of time and space?

Space and time are relative (i.e., they depend on the motion of the observer who measures them) — and light is more fundamental than either. This is the basis of Einstein’s theory of special relativity (“special” refers to the restriction to uniform motion).

What is the meaning of time continuum?

Definitions of space-time continuum. the four-dimensional coordinate system (3 dimensions of space and 1 of time) in which physical events are located. synonyms: space-time.

Can we break space-time continuum?

It’s quite hard to break it when it doesn’t really work in the way that science-fiction teaches us. It’s not really a “fabric” that can be ripped or torn, though it does get stretched and warped by objects of different masses. The more mass an object has, the more it bends spacetime, which is what creates gravity.

Does matter create spacetime?

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.

Is space/time made of matter?

Specifically, spacetime might emerge from the materials we usually think of as living in the universe—matter and energy itself. “It’s not [that] we first have space and time and then we add in some matter,” Wüthrich says. “Rather something material may be a necessary condition for there to be space and time.

Is time the 4th dimension?

Physics > Space and Time According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.

What dimension are we living in?

In everyday life, we inhabit a space of three dimensions – a vast ‘cupboard’ with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.

What are the 3 theories of time travel?

You’ve probably heard of three different theories about time travel: the fixed timeline, dynamic timeline and multiverse.

How many dimension are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

What does it mean to break the space/time continuum?

Is time continuous or quantum?

While time is a continuous quantity in both standard quantum mechanics and general relativity, many physicists have suggested that a discrete model of time might work, especially when considering the combination of quantum mechanics with general relativity to produce a theory of quantum gravity.

Why can’t we reverse time?

Going back in time is unmixing; it can’t be done. The universe can’t be ‘unmixed’. What this means, ultimately, is that time only exists because the Big Bang created a universe that started out ordered. If the universe was disordered from the beginning, there would be nothing left to mix and time would not exist.

Can time be altered?

We Can’t Alter The Flow of Time But, According to Physics, We Can Bend It.

Do magnets bend space-time?

By reanalyzing the basic equations of general relativity, a researcher has discovered that magnetic fields tend to flatten and stiffen the fabric of space-time. The finding might force cosmologists and astronomers to reexamine how magnetic fields have shaped the evolution of the cosmos.

What is the relationship between space time and gravity?

Gravity is the curvature of spacetime Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects.

What is the similarity between time and space?

the analogy between space and time is indeed close. Duration is comparable to extent. A thing may vary in color in its different spatial or in its different temporal parts. A thing may occupy different places at one time or the same place at different times or may vary concomitantly in place and time.

Why matter curves 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.

What did Einstein believe about space and time?

Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.
