SUMMARY

The discussion centers on the limitations of human observation regarding the universe, specifically the observable universe's boundary at 14.5 billion light years. A participant speculates that the universe is significantly larger, potentially containing 7600 million billion galaxies, and suggests that the unobservable portion may be comparable to the size of Jupiter. However, the forum moderators emphasize that discussions involving speculation about unobservable phenomena are not permitted, leading to the thread's closure.

PREREQUISITES
  • Understanding of cosmology and the observable universe
  • Familiarity with the concept of light years as a measurement of distance
  • Basic knowledge of galaxy formation and distribution
  • Awareness of the limitations of scientific observation and speculation
NEXT STEPS
  • Research the concept of the observable universe and its implications in cosmology
  • Explore the methods used to estimate the number of galaxies, such as deep-sky surveys
  • Study the theories surrounding dark matter and dark energy
  • Investigate the tools and technologies used in modern astronomy for observing distant galaxies
USEFUL FOR

Astronomers, astrophysicists, and anyone interested in the fundamental limits of cosmic observation and the structure of the universe.

Hi I'm new to PF...
And... i kinda have to tell you this...
All that we can see is 14.5 billion light years away from us until we reach a spot that's noting...
or at least to our eyes...
First:
-That's the end?:confused:
Second:
-according to some of my calculations the universe is far bigger and has a whole lot more galaxies and wild star clusters and matter in general than we think... here is what I've reached:

If we put 7600 million billion galaxies as the head of this "i" then the rest of the universe is about the size of Jupiter!
We can't see it cause the light of the rest of it just had no time to reach us...:approve:
and right now I'm in the middle of calculating another theoty but i need a bitta help with the first one... Would appreciate it a lot! thanks!:smile:

We cannot observe beyond the observable universe. To discuss what we cannot observe, by its very nature, requires speculation. Since we do not allow speculative discussions here, clearly this thread is beyond the scope of these forums.

Thread locked.
