    Inflation Theory
AI Thread Summary
Inflation theory suggests a rapid expansion of the universe shortly after the Big Bang, distinct from the ongoing expansion observed today as galaxies move away from each other. This theory allows for the possibility of other bubble universes, which could have been formed during this initial inflationary period. The uneven nature of this expansion might result in some regions of the universe being permanently separated from our observable bubble. While the concept remains speculative, it aligns with various astronomical observations. Overall, inflation theory opens up intriguing possibilities regarding the existence of multiple universes.

does the inflation theory say that there could be infanet other bubble iniverses or that our bubble universe is expanding as the galexys move outwards?

I think you might have confused 'inflation' with 'expanding'.

The universe is expanding and other galaxies are indeed moving away from us but 'inflation' refers specifically to a very short period near the start of the universe when this expansion was very quick. It is still speculation but fits other observations very well.

If this quick expansion was uneven then one piece of the universe might have been shifted away from our bit of universe never to come back into contact...
 

Thread 'Does it make sense to build new radio telescopes?'

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?'

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...

Thread 'Our Beautiful Universe - Photos and Videos'

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...
