AI Thread Summary
The discussion centers on the concept of universes beyond our observable universe. It begins with the assertion that, by definition, there is only one known universe, and anything outside it remains unobservable. Participants speculate about the possibility of additional universes existing beyond our visible horizon, suggesting that matter, galaxies, and stars could extend infinitely or curve back on themselves. The conversation touches on the acceleration of the universe's expansion, proposing that external forces from other "big bang" events could be influencing this acceleration without necessitating new physical laws. This perspective implies a diminishing significance of humanity's place in the broader cosmos.

From all of the universies we have recorded or charted is there anything beyond that. Is there just more universes or just matter.

Probably more universe is beyond our visible universe. That is, matter, galaxies, stars, etc.

Just as a clarification, by definition there is only one universe that we know of. And by definition anything outside of it is not observable. Do you mean "galaxies"?

Indeed. Now, it is possible that this
goes on to infinity or that it "curves in"
on itself and you return to your
original location. It is also
possible there is a "limmit" but since
the exapnsion is faster than c - you
can never reach it.

Live long and prosper.
 
one possable explanation for the accelleraration of expanshion, is stuff outside our big bang bubble pulling our stuff outward ever faster
this requires other big bangs outside of ours
but many think a big bang is a local event
so why not many instead of only one.

btw this requres NO NEW FORCES to account for the accellaration or new laws
to be formed

and makes mans place smaller in the general scheme once again
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
