 # How Is Infinity Possible?

## How can the universe be infinite?

If the universe is infinite, it has always been infinite.

At the Big Bang, it was infinitely dense.

Since then it has just been getting less dense as space has expanded.

In the infinite case, you wouldn’t have enough curvature for spacetime to form the hypersphere..

## Can humans understand infinity?

This goes to show that everything depends on perception. … For many of us, it’s easy to understand the concept of infinity, but we can’t comprehend how “big” or “never-ending” it is, because our perception of time always has a beginning and an end — minutes, days, years, lifespans.

## Does Infinity mean forever?

The word is from Latin origin, meaning “without end”. Infinity goes on forever, so sometimes space, numbers, and other things are said to be ‘infinite’, because they never come to a stop. Infinity is usually not an actual number, but it is sometimes used as one. … Potential infinity is a process that never stops.

## What number is after 999 billion?

1 trillionHere is s look into the future. After 999 billion we have 1 trillion. After 999 trillion we have a quad trillion, then we progress onto quintillion, sex tillion (I like that number) and into the Latin derivative for our numbering scheme. Measuring water uses a different scale.

## Is 0 a real number?

What Are Real Numbers? Edit. Real numbers consist of zero (0), the positive and negative integers (-3, -1, 2, 4), and all the fractional and decimal values in between (0.4, 3.1415927, 1/2). Real numbers are divided into rational and irrational numbers.

## Why is space black?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

## Can an actual infinity exist?

Actual infinity is completed and definite, and consists of infinitely many elements. Potential infinity is never complete: elements can be always added, but never infinitely many.

## Do numbers end?

The sequence of natural numbers never ends, and is infinite. There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.

## Is zillion a number?

Zillion is not actually a real number; it’s simply a term used to refer to an undetermined but extremely large quantity.

## Does the universe ever end?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

## What is the farthest thing in the universe?

“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement. “But measuring and verifying such a distance is not an easy task.”

## What infinity means?

Infinity, the concept of something that is unlimited, endless, without bound. … The common symbol for infinity, ∞, was invented by the English mathematician John Wallis in 1655.

## Does the number 1 exist?

The number represented by “1” exists as much as any abstract entity exists, but it does not exist in the way that any physical entity exists. Numbers are abstract entities created by people, and formalised by mathematicians, to have useful properties.
