Bell's theorem is one of the most important contributions to the philosophy of quantum physics. In particular, it is claimed that it undermines either realism in physics or the principle of locality. My response to this is that it undermines certain models of realism, but not all. In this post, I explore this in more depth.

I offer my concluding thoughts on Lawrance Krauss' work A Universe From Nothing, focussing on his preface and epilogue.

I reply to certain recent comments on various posts on my blog.

If you haven't yet done so please check out the classical theism podcast.

I review chapter 11 of Krauss' Universe From Nothing. In this chapter, he argues that the laws of physics themselves might spring forth from a combination of the multiverse and randomness. But where do the laws governing the multiverse come from?.

In politics, we are constantly told that there is a left, a right, and a centre. But is that a reasonable metaphor to use? Are the various political positions points along the same line, or do they belong on entirely different lines altogether?

In this fifth part of a series discussing Professor Lawrence Krauss' work A Universe From Nothing, I have a look at his tenth chapter, where he attempts to show that nothing is unstable.

In this fourth part of a series discussing Professor Lawrence Krauss' work A Universe From Nothing, I have a look at his ninth chapter, where he begins his philosophical discussion. In particular, he attempts to show how the universe could have started from a small patch of empty space. Along the way, he tries to justify his definition of nothing as empty space.

One big debate among philosophers is on the nature of time. The A theory of time states that the division between past, present and future is an objective feature of the universe. The B theory of time views space time as a four dimensional block, and denies that there is a time that we can objectively point to as the present; rather all notions of the present time are either an illusion or merely subjective.

The A theory is the older approach, and was adopted by most people before the twentieth century. It is argued that it is supported by our common experience. The B theory approach found favour after the theory of relativity was introduced, with its support for the four dimensional universe.

In this post I firstly give my own thoughts on the topic, and secondly review the discussion by Edward Feser in his book Aristotle's revenge.

In this third part of a series discussing Professor Lawrence Krauss' work A Universe From Nothing, I have a look at his eigth chapter, where he discusses the small value of the cosmological constant, fine tuning, and the multiverse.
