The Scale of the Universe

It's an interesting way to look at the relative scale of the universe. Kind of makes you wonder if the extreme ends of the scale are really ends at all, or just limitations on our understanding.

I also think it's interesting that there is a limit to the observable universe for the number of lightyears the universe has existed. The vastness of the universe is such a difficult concept to grasp.

Great videos and presentation. Thanks for sharing.

It is immeasurable

All you have to do is look at the size of planets and stars outside of our solar system to see how insignificant we all really are. We all think humans are so important and everything, but when you see a star that is 100 times the size of our sun, it really shows that we don't matter at all.

I would love to be able to instantly travel everywhere in the universe just to see who and what is out there.

In all honesty there is only one thing that you can say on this subject and only one man you should be listening to Stephen Hawkins stated most famously "the universe is expanding" and to the best of human knowledge this is entirely true all we can do is consider if the universe is expanding how long will it continue to expand for. I like to think of the universe as one very large living organism and if you think of it in these terms then generally speaking you could state that every living being has to stop growing at some point, so the real questions are when will the universe stop growing and how big will it get before it stops.

I personally believe the string theory, and liken it more to a slice of bread in the bread store...

i think that is a big universe.

Here's one way of looking at the scale of the universe....

I had thought about the universe as being like a human body when I was a kid. If so, I guess if the universe stops, its matter decomposed and goes to another cycle for others. Then that means, there are others require the universe.

can someone mesure that ? i dont think so lol
lovescience
I just heard a professor described universe as a quantum computer.
Alerrandre
How we can mesure something we dont know the end,and of course i dont know if we have just one universe,maybe thousand of milon universes.

WE have a single universe. That doesn't mean that others don't exist, it just means that this one is one.

Think of it like this: We have an Earth-like planet, "Earth", but that doesn't mean that other Earth-like planets don't exist, just that if they do, they're not this one.

There's a 2012 new version with more details. Much cooler!
This is one of the coolest things I've ever seen.

That is awesome
Haley_Madison
Yes, I love that...I've posted it to my Facebook many times. The amazing thing is that the scale only shows what we have been able to see so far. Mind boggling...
killer2022
It is really mind blowing how large the universe is!
fabfabfb
I m fascinated by the greatness of the universe, but it s also interesting wondering how it s the infitively " small". I mean you can go back to protons, electrons, photons, quarks, and then? Could a quark have got another small particles inside,? And so on. If I pretend to be on that scale, an atom, or a cell, it would be a vey huge universe, isnt it?
playfungames
I watched that animation some time ago and I hope it is accurate. It made me realize (like every other time), how insignificant we are on a universal scale. Yet we live like we are the most important ones on this universe.
cowhitmyface
I love things like this =) shows how small we really are

Looks like the video is out of youtube for some reason.

I love watching the series especially when Amy Mainzer is on it, she's really good looking for a nasa scientist
wallarookiller
Wow. I love things like this that put things into perspective. It starts you in the middle but you can start at quantum foam and string. Pretty crazy.

A human being is helpless when he/she tries to understand the universe.

is there a real scale?

What do you mean by "a real scale"? Are you asking "how large is the [url="http://en.wikipedia.org/wiki/Observable_universe"]observable universe[/url]"? Or "what is the maximum [url="http://en.wikipedia.org/wiki/Chronology_of_the_universe"]lookback time[/url]" (i.e., the [url="http://en.wikipedia.org/wiki/Age_of_the_universe"]age of the universe[/url])? Or maybe, "what is the [url="http://en.wikipedia.org/wiki/Electron#cite_ref-77"]smallest entity[/url] in the universe"?

Let's think: We live on planet Earth, which is within the solar system, which is within the Milky Way, which is within the universe, which is within ... (long pause to think) ... well, the universe must also be inside something. Or not? The truth is that nobody knows. "Within dunno what" may be the best (and only) way to complete that sentence.
But does the universe have an end? Or is it infinite?
If it ends, then it must be contained in something, right? We can not simply floating on nothing! That does not seem to make much sense .... There must be something "other side" of where he ends up. On the other hand, if it has no end, as can be infinite? Everything must have an end, right?! But that brings us back to the initial problem ... '
And then .. do we have a perfect understanding of the word INFINITE? We are inside the finite or in (inside, inside) finite?

Wrong. The Universe may be complete and closed on large scales, with no boundary. Think about the surface of the Earth (not the internal volume, just the surface itself. It has a finite area (about 4*pi*6384^2 square miles), but it does not have any boundary at all. It is not a "piece" of some larger surface somewhere.

Why not?

To you, perhaps. Some further study of non-Euclidean geometry and general relativistic physics seems in order.

A common logical fallacy is to assume that just because you (the generic "you") don't understand something, that something must be wrong.
codegeek
I read an interesting theory, more like a general wondering, that there might be a universe inside every electron. This really forces one to think of the possibilities. Moreover, what if our own universe is a mere electron of a mega-system.

totally out of my imagination... thanks for sharing.
