What are your thoughts about the Universe?

Question

I personally think the universe is finite, despite the meaning of the the word "universe." Sounded by an infinite empty space in which other possible universes (on our plane, not going into quantum physics). Share your thoughts!

Answer 1

and every scientist would agree with you. along with the big bang model the notion of an infinite universe kind of died. there are many logical problems with an infinite universe. and infinite universe means an infinite number of stars. and since time and space are connected an infinite universe would have been around forever, so the light from the infinite amount of stars would have reached earth. so the night sky would be lit up as light, or lighter, than the sky in the day. theres many other illogical things about an infinite universe.

so yes, the universe is finite.

Answer 2

The problem starts out as a problem of definition. If the word "Universe" means absolutely everything, then by definition there is nothing outside the universe. There is just stuff we haven't discovered yet and which will be annexed into the universe once we discover it.

However, if the word "Universe" means everything that we know of so far, then there may be heaps of stuff outside of it that is just waiting to be discovered.

I think we generally consider the 3-dimensions-and-time with all it's matter and energy etc to be "The Universe". It's rather pathetic that we still do not know the most basic and fundamental properties of this "Universe". For example: How many dimensions are there? How did it start? Why does it have the properties that it has? What is it's basic building block (particle, string etc) and why? Was there a Grand Design? Until we do the research to answer these most basic questions, we will always be victim to ignorance and superstition.

Answer 3

Without going into the obvious views stated here I would prefer to describe the universe as a true thing of wonder. It appears to so beautiful from the surface of the Earth, but in reality it is the most hostile of places. Outside the protection of our atmosphere and magnetic force field there is nothing but death dealing conditions, deadly cosmic rays and bone chilling coldness that an unprotected human would succumb to in less than a minute. Above our atmosphere the sun is in full flower, its blinding light obliterates the feeble light of distant stars, all you can see is inky blackness, I can't imagine a more desolate place to be in, the mere thought of it sends shudders up my spine.

Answer 4

Liván is on my wavelength. The universe is a fractal. Link below.

cbirch92 is overlooking a century of counterarguments against Olber's paradox. There are pleanty of reasons why an infinite flat universe needn't be infinitely bright.

Answer 5

The universe is expanding as we speak and will continue to grow until its day comes. Its finite BUT grows at the speed of light. Its constantly expanding and new stars and galaxies are born everyday.

Answer 6

Our universe is of a finite, though expanding, size. However, it is so large, that the immensity of its size is virtually incomprehensible to our imagination (which evolved to deal with much smaller sizes). So in terms of the limits of our cognitive ability it is seemingly infinite.

Answer 7

our universe is debris and left overs of a big explosion in space......if you go millions trillions light years into space and look back our universe would look like a Galaxy but all the little dots that u see would not be a star or a Galaxy it would be a cluster of galaxies......thousands or even millions of clusters form our universe......our universe ends but space never ends....who knows there might be other explosions(universes) in space....

Answer 8

I think we're puppets living in limited space that seems forever to us.

Answer 9

My thoughts about the universe -- everything that ever was, is now, or ever will be.

Answer 10

Well I think in macrocosmos, microcosmos and all is repetitive.........
