A team of particle physicists hope to soon being operation of the most powerful man-made particle accelerator, the Large Hadron Collider (LHC). Although much press has focused on scientists who claim … more

“Test everything. Hold on to the good.” This biblical passage underscores a central principle of the scientific enterprise. Any successful model must undergo testing that will either … more

Where the reader gets to explore the strange effects that could occur when moving beyond the three spatial dimensions in which we live. Unlike time travel, however, there is a possibility that higher … more

The truth of the previous statement relies on (at least) two conditions. First, the monkey must actually use all the keys in a random fashion. Second, but more important, the keyboard must contain all … more

The significance of string theory is that if it or some other multi-space-dimensional theory of physics accurately describes physical reality, then religions that insist on a doctrinal construct of … more

The discussion continues from last week and ends here.

The last description (made in Part 6) leads to an important observation. So far, I’ve discussed and illustrated the projection and the … more

Let’s continue our discussion about cubes from last week, Part 5.

Just as the 3-D cube can be generated with a square by sweeping it out of the plane into the third dimension, the projected … more

The discussion here continues from last week, Part 4.

The 3-D cube in Figure 1 (of Part 4) demonstrates the idea of the projection of an object from a higher dimension to a lower dimension. The … more

This is Part 4 of a discussion on higher dimensionality. In Part 1 I mentioned a story by Robert A. Heinlein in which a four-dimensional cube (hypercube) played a role in the story. I promised there … more

In last week’s entry I responded to 5 (of 10) questions about dimensionality that came up in lunch discussions here at Reasons To Believe. Here are brief responses to the remaining 5 questions. … more

Last time I promised to give some short responses to various questions about dimensionality that have come up in the lunch discussions here at Reasons To Believe. Here are some of them:

Is … more

For many years science fiction writers have used the so-called “fifth dimension” (a fourth spatial dimension) to serve as a platform for telling fascinating stories. These stories have … more

As physicians use scanning devices to view the hidden structures and activities of the brain, astronomers can now use distant supernovae and high-resolution cosmic background radiation maps to scan … more

From a realistic rather than science fiction perspective, the wormhole question is moot. Since black holes are relatively rare, the probability that the singularities of two spatially distant black … more
