Outside Universe

AI Thread Summary

Physicists speculate on the nature of what lies beyond our finite universe, with theories ranging from the existence of multiple universes to concepts involving quantum mechanics. The discussion raises the paradox of defining "outside the universe," suggesting that anything outside would inherently be part of the universe itself. Participants question the implications of these theories and how they challenge our understanding of space and existence. The conversation also touches on the complexities of measuring and defining dimensions beyond our observable universe. Ultimately, the exploration of these ideas reflects the ongoing quest to understand the fundamental nature of reality.

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

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...
