What is beyond the universe for it to expand into?

By definition, the universe is everything, so there is nothing external to it for it to expand into. It is not expanding into anything as such – everything is expanding.

What is the universe expanding out into?

The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.

How can the universe expand if its infinite?

So essentially, if the universe is of infinite magnitude, it cannot possibly be expanding into anything. Rather, it’s stretching (it’s a fine distinction, but an important one). Simply put, every region of the universe, every distance between every pair of galaxies, is being “stretched,” pulled apart like taffy.

What is at the edge of the universe?

As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe.

Can time be defined?

Physicists define time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space.

Is there a multiverse?

Our universe is but one in an unimaginably massive ocean of universes called the multiverse. If that concept isn’t enough to get your head around, physics describes different kinds of multiverse. The easiest one to comprehend is called the cosmological multiverse.

Does a parallel universe exist?

Parallel universes are no longer just a feature of a good sci-fi story. There are now some scientific theories that support the idea of parallel universes beyond our own. However, the multiverse theory remains one of the most controversial theories in science. Our universe is unimaginably big.

What is a Megaverse?

Multiverse, or megaverse, any hypothetical set of multiple universes in cosmology and other disciplines.

How do you enter a parallel universe?

Video quote: Keep moving away from each other as the space fabric between them is being stretched. Well this is happening other universes pop up into existence.

How many dimensions do we live in?

three dimensions

Secret dimensions



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.

Can you visit other universes?

It’s not transporters or spore drives: According to Futurism, theoretical physicist Michio Kaku suggests our universe will eventually wind up in a “big freeze” as expansion slows and stops; combined with technology, this may allow inter-universe transport.

How many dimensions 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.

In what dimension does God live?

Super strings that vibrate in the 10th dimension are what create the subatomic particles which make up our universe and all other possible universes. It is here where God resides.

Are there dimensions we Cannot see?

Physicists work under the assumption that there are at least 10 dimensions, but the majority of us will never “see” them. Because we only know life in 3-D, our brains don’t understand how to look for anything more. In 1884, Edwin A. Abbot published a novel that depicts the problem of seeing dimensions beyond your own.

What is the 7th dimension like?

In the seventh dimension, you have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time.

Is gravity the 5th dimension?

Their model has our familiar four dimensions floating in an infinitely large, negatively curved fifth dimension. While the electromagnetic and nuclear forces are stuck inside a “brane” made of four dimensions, gravity leaks out into the fifth.

Are humans 4-dimensional?

We are discovering that humans are not simply 3D beings. We are actually four dimensional. We are comprised of 4 distinct but integrated parts. Three of which are related to our physical experience – the body, heart and mind.

Does 5th dimension exist?

The fifth dimension is a micro-dimension which is accepted in physics and mathematics. It’s here to have a nice and seamless tie between gravity and electromagnetism, or the main fundamental forces, which seem unrelated in the regular four-dimensional spacetime.

Does 6D exist?

6D is the dimension that helps analyse the energy consumption of elements in the model, so you can perform accurate simulations showing exactly how efficient your chosen light fitting will be and how long it should last.

Can gravity travel across dimensions?

In string theory, graviton is a closed string. As a result, it is not bound to any branes and can easily travel between them as opposed to photon, which is an open string. Therefore, it is said that gravity can travel across dimensions but light cannot.

What is a 6D shape?

In geometry, a 6-cube is a six-dimensional hypercube with 64 vertices, 192 edges, 240 square faces, 160 cubic cells, 60 tesseract 4-faces, and 12 5-cube 5-faces. It has Schläfli symbol {4,3⁴}, being composed of 3 5-cubes around each 4-face.

Are there 100 dimensions?

A 100 dimensional sphere has almost all of its volume concentrated within a narrow band around the equator. Picking it up feels like a flat disc with a really heavy edge. During rotation, it has no fixed-position poles, but can rotate around its 50 equators simultaneously, which has highest stability.

Are Tesseracts possible?

A tesseract is a four-dimensional hypercube with 24 faces, 32 edges, and 16 vertices. It can be created by thickening up a cube in a fourth dimension. Although it is impossible to construct a tesseract physically, we can visualize it in our 3D world.

Is the 4th Dimension real?

Scientists have confirmed the existence of a fourth dimension that Albert Einstein once predicted but could never prove. It is the biggest physics discovery in 50 years and will change the way we view the universe. “Einstein got it right,” said Richard O’Shaughnessy who has worked on this research at RIT.

Are humans 4D or 3D?

three dimensional beings

Humans are three dimensional beings. Objects in 3D space have different lengths, different heights and different widths. Certain theories in physics suggest that our universe may have additional higher dimensions. Humans, being three dimensional organisms, cannot sense or perceive these dimensions.

What did Einstein call the fourth dimension?

Space and Time

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.
