## How many dimensions do we live 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 is inside a Blackhole?

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

## Is time the same in space?

Time is measured differently for the twin who moved through space and the twin who stayed on Earth. The clock in motion will tick more slowly than the clocks we’re watching on Earth. If you’re able to travel near the speed of light, the effects are much more pronounced.

## Can the fabric of spacetime be torn?

According to Einstein’s general relativity, it is impossible to tear the fabric of space. … In 1987, Yau and one of his students found that a Calabi-Yau space could be changed into a different Calabi-Yau space by mathematically puncturing its surface and then “sewing up” the hole.

## What is the fabric of spacetime made of?

The mass has got to curve spacetime, but it isn’t actually a fabric: it’s simply the nothingness that makes up the empty Universe itself. The equations of General Relativity tell us how this curvature works, geometrically, but they don’t tell us how to visualize it.

## Where do things go in a black hole?

It is thought that the matter that goes into a black hole gets crushed into a tiny point at the center called a “singularity”. That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star. Once it’s there, it’s there.

## What is wormhole theory?

The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity.

## What is a tear in space?

In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time …

## Is a black hole a rip in spacetime?

Spacetime isn’t made of something that can rip. A rotating black hole, a “Kerr black hole” is stranger than a static one, as it pulls spacetime around it and can accelerate objects passing close to it. Even so there are no rips, no singularities outside the event horizon.

## Can space be broken?

No. And nor is energy. Energy is the one thing we can neither create nor destroy, and it seems to be intimately related to what space is. But nevertheless the stress-ball does get bigger as the pressure reduces, so it’s reasonable to say space is “created”.

## Can we go back in time?

Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, transversable wormholes, and Alcubierre drives.

## Can space tear?

Spacetime in general relativity is smooth. It can deform—expand, shrink, and bend–but what can’t happen is for it to tear. … Since general relativity tells us that space can vary in size and shape, we expect in quantum gravity that we have to average over all the possible sizes and shapes.

## Is time really a dimension?

There’s a fourth dimension that’s just as important, even though it’s very different: time. We’re always moving forward through time, sure, but it’s just as much a dimension as any of the spatial ones. … But even two different objects with the same exact three-dimensional spatial coordinates might not overlap.

## Does time exist without space?

Special & General Relativity Questions and Answers 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.

## Has anyone been in a Blackhole?

Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.

## Do wormholes exist?

Wormholes are sci-fi staples; over the years, many stories, books and movies have sent their protagonists zipping between widely separated locales via these cosmic shortcuts. … Wormholes are possible, according to Einstein’s general theory of relativity, but nobody has ever spotted one.

## What would happen if there was a rip in the space time continuum?

If we where to rip a hole in the Space-Time continuum, what would happen? – Quora. If we where to rip a hole in the Space-Time continuum, what would happen? … Your topology changing antics will have induced the formation of Closed Timelike Curves, or CTCs for short.

## What do you know about black hole?

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
