Is there more to the universe than what we can see?

AI Thread Summary
The discussion centers on the existence of luminous matter beyond the observable universe and its implications for dark energy and cosmic expansion. Participants debate whether the universe's expansion is driven by dark energy and question the validity of associating cosmic background radiation with dark energy. Concerns are raised about the conservation of energy in relation to dark matter and dark energy. The limitations of observational cosmology are highlighted, emphasizing that the existence of matter beyond what can be observed cannot be definitively proven or disproven. Ultimately, the conversation reflects ongoing uncertainties in understanding the universe's structure and dynamics.

was just thinking if no luminous matter exist beyond the visible part of the universe.
then that indicated that temperature beyond visible part is 0k, then universe expands b/c of dark energy...cosmic wave background noise be a candidate for dark energy since it is the highest radiation in the universe.. the thing about dark matter is in it violating conservation of energy.. how can dark energy come out of no where?.

Sorry, but what you have written really makes no sense at all. Maybe try again using proper punctuation and complete sentences.

Luminous matter certainly exists beyond the observable universe.

then universe expands b/c of dark energy

The universe does not expand because of dark energy.

cosmic wave background noise be a candidate for dark energy since it is the highest radiation in the universe
This doesn't make sense.

the thing about dark matter is in it violating conservation of energy
This doesn't make sense. Dark matter doesn't violate conservation of energy.

how can dark energy come out of no where?.
Why do you think dark energy comes out of nowhere?

There is no way to falsify the existence of anything beyond the "observable universe" so for all intents and purposes there is no saying "certainly".

There is also no way to prove that Earth is not exactly in the center of universe, and that nothing exist outside of our observable patch. But that doesn't make anyone believe that it is so. Observational cosmology is limited with finite speed of light.
 
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...

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.
