Exploring the Helium Reionization Era

Because more energy is required to strip two electrons from a helium atom to form ions than to strip a single electron from an atom of hydrogen, even more time passed befo ...

Discovery Of A Major Contradiction In Big Bang Cosmology Points

Thus, instead of present CBR observations confirming the most important predictions of big bang cosmology, we find they contradict them.
