I'm big but a grain of sand in a billion seas, is still nowhere near as small as me.

it's just a matter of perspective, besides everything is made up of particles anyway so however small; we are part of what makes up the universe.

Does gravity exist?

It doesn't matter, we have no choice but to believe we exist, we are limited to our own perspective, always.

This thread doesn't exist...lol

I know I exist. The rest of you are figments of my imagination...

if say think i do then i do..

We would need to exist to in order to be able to contemplate our existence... right?

elephants sums up everything peace!

What if we are all some form of artificial intelligence, mechanical creatures, some crazy holograms, created by greater beings or something of that sort?

We cannot know whether we exist or not -and it's not even relevant to know. We can't know for sure if we're living in a placebo but does it matter? For example: we would be living in a placebo where we "can" achieve happiness and lots of other feelings. Does it matter if it's "really real" when the placebo feels like so real that it has become its own reality?

Are you really a mathematician...because if you were (I have a Bachelor's in Math, so you might consider me a novice mathematician) you'd know about the essentially universally accepted axiom of choice and how it invalidates your reasoning. You know, that axiom which basically states for any non-empty set (infinite in size or not) there exists an infinite (only if the original set has an infinite cardinality ofc) or a finite subset.

In other words, if we have a group of items, no matter how many, infinite or finite, we can take a subset (a selection of them, which can be the same as the original group of items btw) of those items, infinite (only if the original group of items had an infinite number of items in it ofc) or finite. This subset exists. Thus, if you take the universe as a whole to be a set, there exists a subset of that universe which is solely composed of yourself. Thus your point is completely null and void as you reasoned it out.

On the other hand, to make your case you could present the idea of a holographic universe or the idea that the universe is actually a simulation, but that's another story altogether.

Size differential does not exist.

I do, but I know none of you guys exist. You're all a figment of my imagination while they coop me up and leave me to go inane in the mental institution.

Of course we do. If we don't, then how can you be still here?
