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.

It is quite clear that you can use string theories to say anything you want. I used the term ‘mathematical conjecture’.

In April 2008 the esteemed Michio Kaku said in his Space Show interview, that it would take several hundred years to do gravity modification.  But Michio Kaku is a string theorist himself. And I might add down to Earth one at that, since his opinion contradicts Richard Obousy and Eric Davis.

Then there is George Hathaway also with the Tau Zero Foundation who could not reproduce Podkletnov’s experiments, even when he was in communication with Podkletnov.

And this is the one group our astronaut Mae Jemison, leader of the 100YSS effort, has teamed up with? My sincerest condolences to you Mae Jemison. Sincerest condolences.

For the answer to the second question, you have to look within yourselves.

This video was broadcast on G4TV, September 19th 2012.

http://www.g4tv.com/videos/60838/dr-eric-w-davis-on-new-ligh…g-science/

Major Notes from the Video are:

a. Dr. Eric Davis, Senior Research Physicist at the Institute for Advanced Studies, Austin TX.

b. Use exotic energy, quantum energy from vacuum energy, to generate warp drive by surfing space.

c. Surfing on space at faster than the velocity of light.

d. Theory requires stupendous amount of vacuum energy.

e. Sonny White (correct name?) suggests that it could be done with much less energy.

f. Disruptive innovations can happen at any time.

g. Richard Obousy of Icarus Interstellar Inc, using string quantum theory shows that the limit of velocity is 10E32 x c (velocity of light) using quantum string theories.

Need to bear in mind that for interstellar travel to become a reality three factors must be realized.

1) Costs:

From the video this group has not been able to quantify their costs.

2) Technological Feasibility:

As Dr Eric Davis states it might take anywhere from a 100 year to 200 years for this technology to become a reality, but you never know that some disruptive innovation might change all that.

There is another problem with this. Dr. Robert Nemiroff’s Three Photon Observation, which suggests that quantum foam may not exists, therefore falsifying the ability to do interstellar travel in this manner.

Actually come to think about Dr. Eric Davis was describing Dr. Miguel Alcubierre work but substituting Alcubierre’s General Relativity tensors solutions with ‘string quantum’ theory.

3) Safety:  Don’t know how to navigate or how to protect crew.

That is a fail on all three counts.

Finally, if I remember correctly, the string theories sits on top of quantum theory and therefore all the discoveries in quantum theory have been translated into string theories. But the string theories by themselves have not been able to predict any new physical behavior, in an ‘a priori’ manner.

For a simple description of quantum foam and vacuum energy see, here.

I put forward a test for these type of proposals, in the comments section of an earlier posting,

https://lifeboat.com/blog/2012/10/debunking-antimatter-rocke…lar-travel

And here it is, if you had a few millions dollars can you demonstrate experimental feasibility as a propulsion device?

If the answer is ‘no’ then it is debunked if it is ‘yes’ then let’s get the funding. From Dr Eric Davis comments it is clear that the answer is ‘no’.

Appreciate your comments & feedback.
