Similar to the way archaeologists uncover lost civilizations on Earth by analyzing the artifacts left behind, various researchers believe the past presence of advanced aliens could be detected in a similar manner. This is a reasonable approach. It has historically …

The flow of time, sometimes referred to as the “arrow of time,” is a source of debate, especially among physicists. Most physicists argue that time can only move in one direction based on “causality” (i.e., the relationship between cause and …

Scientists have proposed using “wormholes” as a time machine. A wormhole is a theoretical entity in which space-time curvature connects two distant locations (or times). Although we do not have any concrete evidence that wormholes exist, we can infer their …

Since our discovery of the radio in 1895, we have been beaming radio transmissions into space. Most scientists believe the invention of the radio and radio telescopes would be a natural technological evolution by any intelligent life. Therefore, it would …

Today’s science knows precious little about negative energy. The best example we have of creating negative energy in the laboratory is the Casimir effect, which we briefly discussed previously, but will now discuss in detail. Let us start by discussing …

Without doubt, harnessing sufficient energy is  the largest obstacle to time travel. For example, time dilation (i.e., forward time travel) is only noticeable when mass approaches a significant fraction of the speed of light or sits in a strong gravitational …

Keynote Addresses & Workshops by Louis A. Del Monte I am available to give keynote addresses and workshops. The keynotes and workshops are in four areas: 1. Use Social Media Marketing to Attract Clients and Sell Products 2. Make Change …

Are there any real time machines? In my opinion, we are in about the same place space travel was at the beginning of the twentieth century. At the beginning of the twentieth century, all we knew about space travel came …

There are no existing time machines capable of sending humans forward or backward in time. The closest we have come to time travel is using particle accelerators to cause subatomic particles to experience time dilation (i.e., forward time travel). There …

Comets are sometimes called “dirty snowballs” or “snowy dirtballs.”  There is a lot we don’t know about comets, but here are ten facts we do know: Comets orbit the Sun, similar to the way planets in our solar system orbit …
