December 6, 201114 yr Kepler 22-b: Earth-like planet confirmed Astronomers have confirmed the existence of an Earth-like planet in the "habitable zone" around a star not unlike our own. The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and has a temperature of about 22C. It is the closest confirmed planet yet to one like ours - an "Earth 2.0". http://www.bbc.co.uk...onment-16040655
December 6, 201114 yr Oh hey look, Astronomy gets some relevance. Where were the media when they were finding these similar planets? Well according to General Relativity, 600 light years in terms of time isn't the problem. The problem is achieving near-light speed.
December 6, 201114 yr Well yes, stopping where you want would take a fair amount of energy. But of course... can't start on one problem before you've worked out the other.
December 7, 201114 yr Things can change if the recent experiments hold up where neutrinos went faster than the speed of light. That's almost as exciting as the Marlins signing Pujols.

Yes, but most (including the scientists who have underdone the experiments) genuinely believe that it's a miscalculation. That being said, it doesn't change much of relativity in terms of human interstellar space travel.
December 7, 201114 yr Do you think the awesomeness of Pujols batting back-to-back with Stanton would solve all space travel problems?

Yes, but most (including the scientists who have underdone the experiments) genuinely believe that it's a miscalculation. That being said, it doesn't change much of relativity in terms of human interstellar space travel. It's been run twice with identical results. I still think it was most likely a mistake, but it's a real possibility it wasn't. If it wasn't a mistake, I think that the most likely explanation was that the neutrinos somehow traveled through the "folds" squall was referring to; if that's the case, then it definitely can have significant implications for human interspellar space travel, let alone all of physics.
December 7, 201114 yr Of course it has significant implications for all of physics. And General Relativity will require a lot of tweaking, which in turn will force the same on many other aspects of physics. However, in regards to interstellar space travel, relativity isn't being thrown out of the window in the event that the discovery is agreed upon as true. The general gist of General Relativity will still hold very true. Time will still be relative. From Earth's perspective, it will still always take 600 years to watch our ships go the speed of light for 600 years. This much has been all but proven.
December 7, 201114 yr I prefer the idea of folding space time and skipping to the other side. Insane over simplification but whatevs. Did you learn your physics from Event Horizon too!?

December 8, 201114 yr Absolutely. 600 light years is, relatively speaking, nothing to the size of the universe. 4.2 light years is even impossible given our current technology, and that represents the closest star Proxima Centauri. So, relative to humans our solar system is even pretty 'impossible' in this day and age.

So, relative to humans our solar system is even pretty 'impossible' in this day and age. and thats going at the speed of light (approx 350,000 mph) wonder how long it would take to drive there?

While complying with the speed limit.....

Try 671 million MPH.
December 9, 201114 yr Yeah, but that's not at the speed of light. That's something along the lines of 40,000-50,000 mph.
