The discussion revolves around the question of whether space is infinite or finite, exploring concepts related to the observable universe, cosmic microwave background radiation, and the implications of infinity in the context of cosmology. Participants engage in a mix of theoretical and conceptual reasoning, examining the nature of space, expansion, and the limits of human understanding regarding the universe's size.
Participants express a range of views, with no consensus on whether space is finite or infinite. Some agree on the finite nature of the observable universe, while others propose that the unobservable universe may be infinite. The discussion remains unresolved regarding the implications of infinity and the nature of space.
Limitations include the dependence on definitions of infinity and the observable universe, as well as unresolved questions about the implications of space expansion and the nature of cosmic measurements.

by the way. do you know what neighborhood we live in in the universe? are we close to the core? on the edge? somewhere in the suburbs? Do you know if that's been figured out?
Blueyes5804 said:Thank You. so you're saying there is no "map" of the universe, and because of that, no galactic gps for us. ty. just wondering.
Blueyes5804 said:I would like to know where, in the universe, are we. the milky way I mean. are we in the middle, in the suburbs, out on the farm? where exactly? any ideas?
Blueyes5804 said:How typical that we would think we are the center of the universe! reminds me of when we thought the sun revolved around the earth! lol ty for all the feedback. I find it really interesting!
In Big Bang cosmology, the observable universe consists of the galaxies and other matter that we can in principle observe from Earth in the present day, because light (or other signals) from those objects has had time to reach us since the beginning of the cosmological expansion. Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction—that is, the observable universe is a spherical volume (a ball) centered on the observer, regardless of the shape of the universe as a whole. Every location in the universe has its own observable universe which may or may not overlap with the one centered on the Earth.
