This meetup group was originally developed to explore the meaning, possibilities and potential of time travel. Many books, movies and TV shows have been created, such as The Time Tunnel and The Time Machine, with fascinating and often absurd notions of how time travel can take place. However, can time travel even exist? If so, what is the potential for mankind? Together with time travel there are many other fascinating physical "impossibilities" such as teleportation, faster than light travel, perpetual motion machines, etc., but are they really impossible?

The physicist Michio Kaku's classifies physical impossibilities into three categories:

- Class I Impossibilities: Technologies that are impossible today but that do not violate the known laws of physics. The may be possible in this century, or perhaps the next, in modified form. They include teleportation, antimatter engines, certain forms of telepathy, psychokinesis, and invisibility.

- Class II Impossibilities: Technologies that sit at the very edge of our understanding of the physical world. If they are possible at all, they may be realized on a scale of millennia to millions of years in the future. They include time machines, the possibility of hyperspace travel, and travel through wormholes.

- Class III Impossibilities: Technologies that violate the known laws of physics. If they turn out to be possible, they would represent a fundamental shift in our understanding of physics. Kaku's includes in his book only two class III impossibilities: Perpetual Motion Machines, and Precognition.

The goal of our group is to discuss in what degree what we consider today to be "impossible" may some day become possible, and what its implications would be.

Meetup has allowed me to meet people I wouldn't have met naturally - they're totally different than me.
