Limitations on cosmology for observers restricted to Earth

  1. Oct 12, 2006 #1
    How would our cosmology change once we have the ability to significantly escape our planet, our solar system, or our galaxy? Must we evolve socially or genetically to realize extended space travel? Might we first attain the ability to transform virtually through the cosmos?

    Would the cosmological principle (that the universe is approximately isotropic and homogeneous) still stand? Would interstellar and intergalactic space yield new entities? What currently theoretical phenomena are likely to be discovered? At what point would you estimate that we might find extraterrestrial life, intelligent or otherwise?

    In brief, will our comprehensive, large scale view upon the universe modify radically due to our displaced relative perspective within it?

    Given the discoveries within our own solarsystem showing the ignorance which many base their assumptions on, I'd say the probability of anomalies in stellar parallax in interstellar space is quite high. One could go even as far to say it would vastly reduce the estimated size of the universe.

    Maybe our view of the "above" is similar to a turtle's:

    Perhaps due to such diffraction much of the Hubble deep field images is repetitious or exclusionary, affecting the count of luminous matter.

    The question could be asked whether observers, the cosmos, or both interacting together impose limitations on experiencing physics itself.
