Can space truly be endless and if it is....

a reply to: Sundog1

well its called observable universe for a reason, because there is more beyond what our current technology can see, if it is infinite though we would never see beyond a certain distance our technology would limit us to. even then we'll always be hard limited by how fast light travels.

For now, that is one chance we have over the bots. As the Great Reset comes in, the WEF plan does rely on the lights staying on. There is a lot in human nature the bots still need to learn, they are limited by numbers, infinity does not compute for them.

As for us, I like the story 'War of the Worlds', we have millions, if not billions of years of evolution that define the right of our existence. They better have there # together if that want to take Earth on.

When you get to the END of space you hit a wall.
just like the flat earth. um! wait!!

It only seems endless because it's so vast.

If the multiverse theory is correct, our universe is just a bubble in an ocean of bubbles.

If that's the case though, what happens when you reach the limits of that bubble?

You can't go any further and yet there's no brick wall.

Do you start again at the opposite end?

Pi is not an abstract concept. It is an infinite number something that should not exist in your universe.

a reply to: Nickn3

For all intents and purposes it is endless.

Whether it goes on into infinity, God only knows...

I've seen the pictures of deep space, where all those little twinkly lights are flippin' galaxies--each with perhaps millions of stars...

The Universe is vast beyond our comprehension. Infinite or not, it is infinite.

Nah man. You just pop up on the other side of the map lol

this universe, any universe, everything that is, is a creation of consciousness.

wether this universe - as in, space as we see it - is endless, is meaningless. it likely is, but you should also factor in our perception of time. we cannot see the universe as it is, because the light that reaches us, is billions of years old.

heck, we can't see most of the things in our vicinity anyway, let alone in the stars.

a reply to: Sundog1

I don't know if it is endless or not (neither does science know), but the observable universe is almost surely smaller than the actual universe. And by observable, I don't mean with our current telescope technology, but even with future, more powerful telescopes.

That's because there are galaxies that are so far away, and because the expansion of space space means we are moving away from those unseen galaxies at greater than the speed of light -- so the the light from those galaxies would never reach us.

We can only see 13.7 billion years back, then we just see cosmic microwave background radiation. Our field of view covers 92(edit)billion light years (a sphere with a radius of 46 billion light years), this has something to do with cosmic inflation, and the ongoing expansion of space, in other words, although we can only see as far back as 13.7 billion light years, because the objects that emitted the light have themselves been shifted by the expansions, the outlying objects are now at a theoretical distace of 46 billion light years away. We will never be able to see further no matter how powerful the telescope, seeing further means seeing beyond the CMB radiation, which means seeing right back to the big bang, all we can do is wait for the light from further away to arrive.

a reply to: Chinaski

I'm probably missing something obvious, but why do we always look 'back' when we peer into space? If the universe erupted from a singularity then, assuming our galaxy isn't at the forefront of that expansion, there should be galaxies further away from the singularity than ours.

a reply to: Sundog1

When thinking about this thread the thought hit me that both answers are right. This Universe is finite, and infinite at the same time. but there is an infinite number of universes. ?

a reply to: coughymachine

By "looking back" they mean that we're seeing light that left stars and galaxies millions or billions of years ago. So we're seeing into the past.

Say if we had a telescope that spotted a civilization on a planet 1 million light years away. We'd be seeing that civilization as it was a million years ago.
If we could go there, they might be gone, because they may have wiped themselves out in the intervening million years.

I think it's likely that space is infinite.

The universe (all the galaxies) is expanding out into the infinite space.

a reply to: Sundog1

No , I just heard " Somewhere " that Our Universe is Not ENDLESS and Constantly Expanding . It has a Limited Threshold .

a reply to: watchitburn

I phrased my question incorrectly. Apologies.

What I meant was: why, whatever direction we point our telescopes in the night sky, do we seem to be looking back to the moment of the big bang? This question assumed there was a point of origin for the big bang.

I've since read that there is, apparently, no single point of origin relative to us for the big bang; and that any given point in the universe, including where we are right now, can be considered a point of origin... a concept I can't quite get my head around.

a reply to: Soylent Green Is People

My (limted) understanding is that, the deeper we look into space, the faster space is expanding; and that this rate of expansion appears to be linear. Also, at some point beyond the current visible universe, space is expanding faster than the speed of light, which means we would never be able to see any light emitted from any galaxies at or beyond that point.

So, my question is: how would light behave in a region of space that was expanding at exactly the speed of light? Would light in that region stand still?

a reply to: Dapagaa “set” is a finite group of numbers, so not infinite.

a reply to: 00018GE

but in a finite universe, there should be "Nothing that is infinite" not even the concept of infinity, let alone an infinite series of numbers like PI

a reply to: anonentity

Doesn't pi itself demonstrate that something finite can coexist with something infinite? Pi can be expressed as an infinite sequence of numbers, but it describes a concept that is finite, i.e. the relationship between the circumference of a circle and its diameter.
