Why Does Anything At All Exist?

Here's my lecture at SUNY Albany in late February 2012 on Leibniz's Cosmological Argument from Contingency.

  2. Is it plausible that there was a series of big bangs? The premise is that matter is eternal, expands after a big bang for a few trillion years or so, then collapses and repeats.

    1. The oscillating models have been universally rejected by most cosmologists and astronomers today. This is mainly due to the fact that entropy would require each bounce to be larger than the one before, and therefore going back in time to the smallest bounce or singularity, which is what the model intended to circumvent. Also, the Borde, Guth, and Vilenken spacetime theorems prove an absolute beginning to space and time, matter and energy. Therefore, matter is not eternal, but began to exist a finite time ago and was created, not from a material cause, but from an efficient cause (God).
      Remarkably, the hot big bang model is still the most tested and resilient model today. We can measure the temperature of the cosmic background radiation left over from the big bang and it matches the temperature predicted by Einstein's theory of General Relativity to a high degree of precision. Einstein's theory also pointed to a singularity, which he sought to avoid by introducing his fudge factor, the cosmological constant. Yet, his discovery and model's predictions only buttress the fact that the universe began to exist a finite time ago, and astronomers measure that to be about 13.72 billion years ago.
