The Universe is ezpanding, and increasing in it's rate of expansion. Eventually after all the stars have burned their Hydrogen into helium, that will be it. The Universe will still exist but it will be a "dead universe", no new stars or galaxies. Pretty grim but that's the way it is.

my question is, can true nothingness exist?

If the universe is expanding into nothingness, well that means the "nothingness" is given definition by the "somethingness" and is no longer nothing.

If the universe came from "nothing" there had to be potential there, so in strict terms there was something there.

Is there a way to philosophicly prove nothingness? Scientificly prove?

I tend to think the universe is holographic, but that's a whole other story.

What do you guys think of multiple universes? Perhaps we are just one universe of many, but that, due to our own scientific limitations and the vastness of our own universe, we just haven't seen it?

Looking at science, in general, rarely are single things created. Even stars are usually made in pairs (Jupiter is our sun's dead twin).

Who said that?

The universe came from something that was always there and always is, yesterday, today and tomorrow; just like Love simply is.

Hm... If a shadow is non-light, is it nothing?

Unless I misunderstood who Sting2 was responding to, I believe he said it was expanding into nothing.

My answer philosophy wise is no. It's been defined by it's parameters and therefore no longer nothing.

Science wise, there are things that don't give off light that are something.

I think so anyways, I had a rough night last night and am not thinking to clearly. What do you think?
---

It's just something I've been thinking about for a while. People talk abotu the emptiness of space, but it's not empty. People talk about nothing, but I don't believe nothing can truly exist.

Melon,

I tend to think there are multiple universes, but for reasons that probably differ from most. I'm too tired to get into it now, but I do belive they exist.


---

I was wondering, for those who do believe they exist, What do you think thier nature is?

Various timelines, basicly alternatives to our universe?

A universe seperate, but like ours in most general ways?

A universe that acts more like a dimension, where the laws of physics and nature could be completely different from what we know?

or something else?

I believe in multiple universes too. I think they are all connected in some way. In different universe, the laws of Physics are the same as this universe that we're living, but the timelines are completely differ from ours.


And about the emptiness of the space beyond the universes, I'm always thinking and almost fighting constantly with myself for this! At this moment, I believe that there're really nothing out there. It's hard to imagine, but those x-dimensional spaces are hard to imagine either.

After reading that second link - my question is - so did the trees really vanish or did the lady just convince the onlookers that they were no longer there, so they deleted them from their holograms?

This explains the power of suggestion and also gives weight to the theory of osmosis.

I think for all intents and purposes, both. Though I don't think the trees were deleted, the people just stopped percieving those wave patterns.

Did anyone else see A Brief History of the Universe - based on Stephen Hawkings book? It talked about the idea that is the universe came from a big bang and is expanding, does that then mean at some point it will reach its stretching point and shrink? Will time travel backwards and history become our future? Afterwards I needed a nap. <brain cramp>

Science fiction. Assuming that the universe eventually does contract and start coming back together, why would that mean that time would reverse as well? I think time travel is complete science fiction for the only reason that I don't think time, in itself, is "recorded" whatsoever. Time is just a series of "present" moments that cease to be "present" instantaneously. Past/future...all human concepts. All we have is the present, folks, regardless of our location or the size of the universe.

There's a few things I'd like to address:

1. The universe is defined as everything that exists.

2. The universe is finite. How do I know? Look at it mathematically. I am finite. I am also an aspect of the universe. If you divide any number by infinity, you always get infinity. I am 1. 1/infinity=infinity.

3. Due to the very nature of the universe (all that exists), multiple universes cannot exist. If they did, what would they all be a part of?

------------------

Truth is offensive.
I'm morally opposed to rape, and I would never rape anyone, but I think, ultimately, it's up to the rapist and no one else.

that's how it should be defined, but often people define it differently.

I'm just talking out of my ass here, but that reasoning just follows along the lines that you are part of the infinite, not that the infinite doesn't exist.

I think what people usually mean by multiple Universes is multiple dimensions within the universe defined as a whole.

I don't think it would reverse time either, but it would certainly have some interesting effects since time, gravity, weak nuclear, strong nuclear and many more I'm too tired to mention at the moment, are all intertwined together.

you may be right, I don't think we'll ever know on this plane. But time and the universe could also be fully formed. We may just be experiencing and moving through it in this direction.

This of course has ramifications on the concept of free will, as do the ideas of multiple universes, but it's a theory that can't be discounted.

For what it's worth, I don't think actual time travel, in the way that science fiction uses it, is ever going to be possible.

First, the current scientific consensus to my knowledge is that the universe is not only expanding, but accelerating, thus making the problem of collapse and reverse time travel not something to worry about.

Also, theoretically, time travel is not science fiction. From Discover Magazine, March 2002, page 75...

"Einstein established that a limited form of travel into the future is possible. According to the special theory of relativity, rapid motion or a strong gravitational field can noticeably slow the passage of time. If you set out in a very fast spaceship at 87 percent the speed of light--161,000 miles per second--you'll see time pass twice as quickly for the rest of the world as it does for you. Press on closer to the speed of light, and you can race ahead even more rapidly into the future.

Going into the past requires a great deal more work..." It goes on to describe how that would be accomplished, theoretically.

So, just because we don't know how to do something or don't completely understand it doesn't mean it doesn't exist.

Also, I don't remember who brought it up entirely, but there is a very interesting article about the existence or non-existence of time in Discover Magazine, December 2000, entitled "From Here to Eternity." In it, physicist Julian Barbour argues several interesting points:

1. Time is an illusion, a creation of human perception.

2. If time is removed from the foundation of physics, new theories are needed to explain why humans experience the sensation of passing time.

3. "Each stage of a person's life--from fetus to young adult to senior citizen--eternally coexists with all others." "Each instant has a content, and that content is eternal." Thus, we're all immortal.

Some pretty heavy stuff to wrap your mind around, admittedly, but that's just some tidbits from the article, which does a great job explaining theories of time. It is interesting, to say the least, to try to justify Einstein's theories with Barbour's. I also recommend reading St. Augustine's Confessions, which has some pretty interesting philosophical arguments on the nature of time which are still relevant today 1700 years later. Or has it really been 1700 years?
