I mean look at a triangle or a square or even a sphere kind of has something outside of it. Even a circle does.

when something has a limit at infinity so there must be a boundary somewhere..
there is a theory that we actually are living in a black whole , in fact the whole big-bang process was a birth of a black whole which clearly defines the existent of parallel universes
i really fascinated by that idea it COOL
... in Euclidean geometry, parallel lines will not intersect. However, in real space they do.the most obvious example for continuity and limitless is two parallel lines right
That is what scientific method is all about.how could you be that sure about the truth

You check your ideas against the Universe.
But it is not an on/off thing - the methods allow you to work out how confident you can be in a particular answer.
gave you?
The standard big bang model is still the best and most parsimonious fit to cosmological data.arashbh said:t
the BB idea has become a bit old it used to be the best idea!..
arashbh said:i meant the BB being a start point might not be true..as Prof. Kaku explains it
i did happen but it wasnt the first time
Yes, and I think we're all in agreement, but that specific question might not be answerable even in principle with cosmological observations. The standard big bang model certainly doesn't address it.arashbh said:i meant the BB being a start point might not be true..as Prof. Kaku explains it

And Phinds -- I couldn't agree more with your appraisal of Kaku.
phinds said:Kaku talks about wildly speculative ideas as though they were fact, including such unproven and currently unsupported speculation as this. He used to be a real physicist but he is now a popularizer of the worst sort.

The term "unbounded" refers to the idea that the universe has no physical boundaries or edges. This means that there is no defined limit or endpoint to the universe, and it continues on indefinitely.
Scientists have come to the conclusion that the universe is unbounded based on various observations and measurements of the universe's expansion. These include the observation of cosmic microwave background radiation and the measurement of the universe's critical density, which suggests that the universe has infinite volume.
While an unbounded universe does not have any physical boundaries, it does not necessarily mean that it is infinite in size. The universe could still have a finite volume but with no edges or boundaries.
The concept of an unbounded universe is closely related to the Big Bang theory. According to this theory, the universe began as a singularity and has been expanding ever since. The fact that the universe is unbounded supports the idea that it has been expanding for billions of years.
Yes, there are some theories that suggest the universe may be bounded. For example, the "Big Crunch" theory proposes that the universe will eventually stop expanding and start contracting until it collapses in on itself. However, current observations and measurements suggest that the universe is unbounded and will continue to expand indefinitely.
