Lemaître’s Limit(s) to our Universe(s)

Lemaître’s Limit(s) to our Universe(s)
By: Ian Steer, RASC Toronto Centre

Georges Lemaître gave a theoretical proof for his 1927 doctoral thesis in astronomy that the maximum spherical radius of our Universe can be computed from first principles to be 14.2 billion light-years. That estimate, which is known as Lemaître’s limit, is within 3% of current estimates of the Universes age. Further, the most precise estimate of the Hubble constant to date, H = 69.3 km/s/Mpc from the full nine-years of Wilkinson Microwave Anisotropy Probe measurements, is within 1% of the value predicted based on Lemaître’s Limit, H = 68.7 km/s/Mpc. If Lemaître’s Limit is resurrected, it will revolutionize cosmology.

This talk will expand - pardon pun - on my latest JRASC paper, Lemaître’s limit (see JRASC 107, 57-62, April 2013, and arXiv preprint at http://arxiv.org/abs/1212.6566)
