"Dark Energy Theory May Explain Early Universe Radiation"
Originally Published 2 years ago — by Yahoo! Voices
New research suggests that the strange radiation signal emitted when the first stars appeared in the universe may be evidence of an evolving, dynamic kind of dark energy. Astrophysicist Lu Yin has explored a model called interacting Chevallier-Polarski-Linder dark energy, or ICPL, which allows for dark energy to interact with dark matter, resulting in changes in the acceleration rate of expansion. Yin found that this ICPL model caused stars and galaxies to appear earlier than in standard cosmological models, which made the ICPL model better at accounting for the strange observed 21-cm signal compared with traditional cosmological models.
