A few years ago I questioned the distance of an object whose age placed it during or before what is referred to in modern cosmology as the Epoch of Reionization. This is supposedly a period shortly after The Big Bang when stars and galaxies first started to form and began reionizing the neutral hydrogen in the Universe that was formed even earlier after The Big Bang. I predicted that eventually objects would be found with […]
2015: The year of the missing gravitational waves
This year was not kind to gravitational wave researchers despite multiple experiments across various instruments both on Earth and in space. Gravitational waves are ripples in space-time predicted by Albert Einstein in 1916 using his Theory of General Relativity. He theorized that gravitational waves carry energy away from accelerating masses in the form of gravitational radiation much like photons carry away energy in the form of electromagnetic radiation. But because gravity is 1039 (yes, that’s a thousand trillion […]
