I'm interested in developments concerning the 'Alcubierre Warp Drive', specifically, the arrival problem: http://www.extremetech.com/extreme/...nihilating-whole-star-systems-when-you-arrive established in this paper, by a group from Australia: http://d1jqu7g1y74ds1.cloudfront.net/wp-content/uploads/2012/02/MatterOfMatter-revised-final.pdf I found a news article claiming that the problem turned out to be false, based on a mathematics error: https://www.extremetech.com/extreme...hip-called-enterprise-of-course#disqus_thread I could not, however, find any source to corroborate this. I even emailed the author of the article, who did not want to revisit the article and offered little information and didn't seem to remember his source, although he provided a link to a paper by Dr. Harold White of Eagleworks, NASA, in which he thought it was addressed: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjym4WQuIHSAhVH74MKHRIjChMQFggcMAA&url=http://www.amarketplaceofideas.com/wp-content/uploads/2014/08/201100159361.pdf&usg=AFQjCNG9SIgNFLPa237i-rqNY03Dk59a8A&sig2=kwOEbTqyTUO5ynXe9LWfWQ I read through most of this and did not find a mention of the 'arrival problem'. I then attempted to contact Dr. White himself about the problem, twice, by email, with no response. So, that brings me to this forum. Is anyone aware of any mistake in the paper by the Australian group? To what extent has it been peer reviewed? Thanks all!
