Explanation:
How will our universe end?
Recent speculation now includes a pervasive growing field of
mysterious repulsivephantom energy that rips virtually everything apart.
Although the universe started with a
Big Bang, analysis of
cosmologicalmeasurements
allows a possibility that it will end with a
Big Rip.
As soon as few billion years from now,
the controversial scenario holds,
dark energy will grow to such a magnitude that our
own Galaxy will no longer be able to hold itself together.
After that, stars,
planets, and then even
atoms might not be able to withstand the
expansive internal force.
Previously, speculation on the
ultimate fate
of the universe centered on either a re-collapsing
Big Crunch or a
Big Freeze.
Although the
universe's fate
is still a puzzle,
piecing it together will likely follow from an
increased understanding of the nature of
dark matter and
dark energy.

Die dunkle Energie wird seit einigen Jahren in Astrophysik ernsthaft diskutiert. Sie wird für die Ursache der beschleunigten Expansion des Unversums vermutet und macht, gemäss Messwerten der Mikrowellenhintergrundstrahlung, ca. 75% der Gesamt-Energie des Universums aus.
Von phantom energy habe ich noch nie etwas gehört. Vielleicht ist das nur eine Synonym um den rätselhaften Charakter der dark energy zu unterstreichen.
Von der hab ich auch noch nie was gehört. Hat auch nur einen stub auf der englischen Wikipedia:
Phantom energy is a hypothetical form of dark energy with equation of state w < − 1. If it exists, it could cause the expansion of the universe to accelerate so quickly that the Big Rip would occur.
One application of phantom energy in 2007 was to a cyclic model of the universe.
