Submission + - Do We Live in a Giant Cosmic Bubble? 1

Khemisty writes: "Earth may be trapped in an abnormal bubble of space-time that is particularly void of matter. Scientists say this condition could account for the apparent acceleration of the universe's expansion, for which dark energy currently is the leading explanation.

Until now, there has been no good way to choose between dark energy or the void explanation, but a new study outlines a potential test of the bubble scenario. If we were in an unusually sparse area of the universe, then things could look farther away than they really are and there would be no need to rely on dark energy as an explanation for certain astronomical observations. "If we lived in a very large under-density, then the space-time itself wouldn't be accelerating," said researcher Timothy Clifton of Oxford University in England. "It would just be that the observations, if interpreted in the usual way, would look like they were.""

    In the Summer of 1923, the Script's Monkey Trial: Believers proved they had so little, or no comprehension of spirituality, that science, got a free hand to teach theory, in school curriculums. During the 83 years since the Creation/Evolution argument began; neither side has been able to positively validate their opinion (belief/theory) as truth.
