how do you explain the concept of infinity?

Answer 1

Usually in the same way you explain a limit.

A limit is infinity if for any number you can name, I can give a value x so that f(x) is greater than your number. Then I can say that f(x) approaches infinity.

Or just say this. For every number you can name, I can name a bigger one. Therefore, numbers are infinite.

Answer 2

infinity is strictly a mathematical concept.
Even the concept of nothing,before the universe began is not infinite.
The only infinity that can exist is this;an incident has a beginning it runs it's course then comes to an end.
The incident never happens again so the state of it's nonexistence is infinite.

Answer 3

The best answer I got is from my math teacher: Infinity is something extremely large, larger than anything large, no matter how large is that large thing.

It is a little difficult to understand this statement, but the Sun, Moon and planets were once considered to be infinitely far; after greek astronomers started to study their motion, it became apparent that these distances are not infinite, although nobody was able to measure them until Kepler. The stars, however, remained at infinity until less than 200 years ago.

Answer 4

There is a new definition that mother nature gives us. The center of the galaxy is a black hole,which is formed by a star collapseing and the collapseing acceleration parts to the speed of light . That is suppost increases the mass to infinity according to E=MC^2. Which causes a gravity well that can be 100 light years across.

Answer 5

It's not fake, but it can't be explained rationally.

Imagine how long you would have to think to figure out the answer to this question on your own (if there is one)... I'm pretty sure that will be approaching infinity (if there's such a thing as close to infinty, lol).

To try cut a long story short, it's a never ending story.

Answer 6

It is a convenient (if incomprehesible) mathematical abstraction of the concept of "one more than the biggest number that you can count". You can get the idea of it by repeatedly dividing one number by another.

Keep dividing 1 by 2 - gets closer to zero but never gets there.
Keep dividing 1 by .1 - gets closer to infinity etc.

Answer 8

Something which never comes to an end... Even a number written in illegible 1-point fontsize which is written like this:
1000000000...
with zeroes extending the length of the visible universe (~23 billion lightyears) isn't infinity.

Answer 9

It is a really hard concept to realize because we are used to finit stuff, like us, the trees the continent, the earth, but really the infinity its just that something that never end, like the space, try to conceptualize the real meaning that the space never ends its reallly mind boggling

Answer 10

Beyond human limitation to measure. An object in the Space is at Infinite distance until you come up with an exact measurement.
