On The Edge of Space and Time

Using the image on the left as a guide, image a metal plate with a hole in the center that is being heated. We know that heating metal causes it to expand , so the arrows indicate how the plate will expand. The question is what will happen to the hole? Will the forces applied cause it to get bigger or smaller?

Please take a moment to to quickly decide on one of the following positions before reading further:

1) The hole will get bigger
2) The hole will get smaller
3) I'm just not sure

Let's ask the same question in a different manner. Suppose there is a bolt stuck in a metal hole. If the metal is heated, will that loosen the bolt and make it easier to remove? Yes or No?

Generally, looking at the arrows in the diagram causes confusion. They all appear to be pushing against the diameter of the hole in a way that should make it smaller. Yet that just doesn't feel like a right answer and Position 3, being not sure, is a typical first reaction. Asking essentially the same question without the "helpful" diagram is much easier to answer. Even the mechanically challenged, like myself, imagine the bolt getting looser as the metal heats. The correct answer, which we all intuitively know, is heating the metal plate will cause all dimensions to increase, including the hole's.

Why is it difficult for most of us to quickly see what we know as obvious in that problem? This is really an illustration of two principles. The first is we tend to make decisions using an "Anchor and Adjust" strategy. In this case, the misleading illustration was put first to set it as a mental "Anchor". Then when we try to answer by Adjusting from that image, we run into difficulty because of the apparent shrinking effect of the arrows. Anchor and Adjust is very powerful and will be described further in future postings. The other principle is that even though we know this is an expanding universe, we are easily suckered into acting as if it were shrinkable.

The general acceptance of Hubble's Law and The Big Bang Theory has spread the knowledge that the universe must continue to expand; however, we tend to think of that as something only related to astronomy. Each of us are on the very edge of the space-time continuum and each passing moment of our lives moves our edge further outward. A popular metaphor is to imagine an ant on a balloon. Our ant's "space" (along with all the other ants) in space-time must expand as the balloon of the universe inflates (expands). We are all always in a place of expansion. The universe has no other way of acting. No matter how it appears, it's just not shrinkable.

The Active Investor, a business owner or professional, initially believes in an expanding universe. Time and circumstances wear on us all and we all eventually face "arrows" that indicate we were wrong about the universe. If that conclusion just doesn't feel right, there is every good reason to believe it's just so much junk science obscuring the truth. A suitable path out of the circumstance is to take gentle yet powerful actions that do feel right and to repeat them until feelings coincide with situation.

This blog is written to inspire good feeling thoughts that lead to actions. They will manifest themselves if we seek them. They have to. It's our part in the expansion of our edge of the universe.
