how big is everything?

Big enough to contain everything.

Philosophically speaking. It depends. Do you want to adopt "metric system" or American-British unit" . Do you want lengthwise, widthwise or breadthwise. Do you want to measure its weight or volume or height.

I hope to make it easy for you to know how big things are.

Everything from atoms to galaxies.

The idea is to have rooms with different magnifications.

In one room, you are Godzilla, and people are the size of ants.

In the next room, the world looks like a road map.

And in the room after that, the Earth is a blue-white marble, floating in space.

Just ten rooms get you from your teeny tiny atoms to our really BIG Milky Way galaxy.

The next neat thing is that you already have a feel for how big some things are.

If I ask you, "How big is a can of soda?", you already know!

You are not going to think it is as big as your bathtub... no way.

And you are not going to think a can is as small as your finger.

You've held soda cans, and you know how big they are.

So we are going to do the same thing with buildings.

And with planets. And bacteria. And lots of other stuff. :)

We can even do some of them for real, making models we can really hold.

(Like a little Statue of Liberty. Or a virus that looks like a baseball with spikes).

So, that is what I'd like this site to do for you.

To help you get a feel for the "sizes of everything".

Unquote:

Everything that is too tiny to see is very small. Everything we can see is small to massively huge. I wouldn't worry about the rest, but there's a lot of it.

Scale

Every thing is big or small in relation to each other.

ITs flipped out onto itself like the massivley big grows back to the smallest particles

Not big at all

How big is everything?

~~~ 'Everything' (the Universe) cannot be measured!

As big as your mind cannot perceive.

"Everything"??

It's quite immense.

It's so immense that it's immeasurable!
