How can the universe be infinite and expanding?

It is also possible that our universe is infinite. In both examples, groups of galaxies completely fill the universe and are moving apart at all points making the universe expand (see question 2).

How can the universe be infinite if its expanding?

The other answers simply explain that an infinite universe can continuously expand because the increase in size is filled with space, not new matter.

Can the universe be constantly expanding?

The expanding universe is finite in both time and space. The reason that the universe did not collapse, as Newton’s and Einstein’s equations said it might, is that it had been expanding from the moment of its creation. The universe is in a constant state of change.

Is time finite or infinite?

As a universe, a vast collection of animate and inanimate objects, time is infinite. Even if there was a beginning, and there might be a big bang end, it won’t really be an end. The energy left behind will become something else; the end will be a beginning.

Can infinite grow?

“Infinity” cannot increase. Period. A space can grow larger, but not “infinity”.

How can infinity exist?

Although the concept of infinity has a mathematical basis, we have yet to perform an experiment that yields an infinite result. Even in maths, the idea that something could have no limit is paradoxical. For example, there is no largest counting number nor is there a biggest odd or even number.

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.

What created the universe?

the Big Bang

Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

Can something be created from nothing?

Something can be created from nothing



But such a perfect vacuum may not exist. One of the foundations of quantum theory is the Heisenberg uncertainty principle. It begins to be of profound importance to our understanding of nature at the atomic scale and below.

What is inside a black hole?

The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist.

Is there a white hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

Can a wormhole exist?

Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

Is Earth inside a black hole?

Our universe may reside within a vast, black hole. Let’s rewind the clock. Before humans existed, before Earth formed, before the sun ignited, before galaxies arose, before light could even shine, there was the Big Bang. This happened 13.8 billion years ago.

Can a black hole swallow a galaxy?

Is it possible for a black hole to “eat” an entire galaxy? No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.

How do you destroy a black hole?

Video quote: There is nothing we could throw at a black hole that would do the least bit of damage to it even.

Are there multiple universes?

There is not one universe—there is a multiverse. In Scientific American articles and books such as Brian Greene’s The Hidden Reality, leading scientists have spoken of a super-Copernican revolution.

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.

Are there infinite planets?

In fact, scientists today believe it’s very likely there are infinite versions of our planet and ourselves out there somewhere.

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.

Are humans 3D or 4D?

Thus, each human face possesses concurrently a unique volumetric structure and surface pattern in three dimensions (or 3D) and a temporal pattern across time in four dimensions (or 4D).

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.

How are space and time related?

Einstein, however, introduced the concept of time as the fourth dimension, which meant that space and time were inextricably linked. His general theory of relativity suggests that space-time expands and contracts depending on the momentum and mass of nearby matter.

How long is 1 year in space?

**One year in space would be 365 days /1 year on earth…..

How long is 1 second in space?

It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).
