100YSS A Success

Posted by in categories: education, events, fun, human trajectories, physics, scientific freedom, space

I am very pleased to say that the 2013 100YSS conference held in Houston, TX, was a success. I met a lot of like minded people — people who want to make interstellar travel a reality — though we differ in our opinions of when.

I was especially pleased to be able to visit with Mae Jemison, Jill Tarter and Pamela Contag. These three are amazing, shepherding us along. Shepherding us? Yes, are a loose collection of visionaries going every which way.

Gravity Modification – What Is The Record?

If, we as a community, are intending to accelerate the development of interstellar travel we have to glower at the record and ask ourselves some tough questions. First, what is the current record of the primary players? Second, why is everyone afraid to try something outside the status quo theories?

At the present time the primary players are associated with the DARPA funded 100-Year Starship Study, as Icarus Interstellar who is cross linked with The Tau Zero Foundation and Centauri Dreams is a team member of the 100YSS. I was surprised to find Jean-Luc Cambier on Tau Zero.

Gary Church recently put the final nail in the Icarus Interstellar‘s dreams to build a rocket ship for interstellar travel. In his post on Lifeboat, Cosmic Ray Gorilla Gary Church says “it is likely such a shield will massive over a thousand tons”. Was he suggesting that the new cost of an interstellar rocket ship is not 3.4x World GDP but 34x or 340x World GDP? Oops!

Let us look at the record. Richard Obousy of Icarus Interstellar and Eric Davis of Institute for Advanced Studies claimed that it was possible, using string theories to travel at not just c, the velocity of light but at 1E32c, or c multiplied by a 1 followed by 32 zeros. However, Lorentz-FitzGerald transformations show that anything with mass cannot travel faster than the velocity of light. Note that Lorentz-FitzGerald is an empirical observation which was incorporated into Einstein’s Special Theory of Relativity.
