AI Thread Summary
The Big Crunch is a theoretical scenario for the universe's end, but current physics does not provide a definitive answer regarding its possibility. Presently, observations indicate that the universe's expansion is accelerating, suggesting an open universe rather than a Big Crunch. The concept of the "end of the universe" is subjective, as it could refer to various outcomes, including Heat Death. Future discoveries in physics may alter our understanding of cosmic fate. Ultimately, the question remains open due to the limitations of current knowledge.

hi frns,
is big crunch explainable by todays mathematics? is there any end to the universe?
 
Astronomy news on Phys.org
Whether or not the universe ends in a big crunch is a question of physics, not mathematics. Current physics theory does not have a definite answer. As far as can be ascertained, the expansion of the universe is accelerating. Continuing in that direction leads to a completely open universe. However, we don't know enough to say things won't change in the future.
 
Also depends on how you want to define "end of the universe". A Big Crunch would be a definitive end to be sure, but there are other possible "ends" such as Heat Death where nothing interesting ever happens again. (setting up for a joke here...)
 

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...
