The Three Possible Classes of Interstellar Travel (forbes.com)

Posted by Soulskill on from the warp-drive,-hyperdrive,-and-boring-drive dept.

An anonymous reader writes: The stars call to us through the ages, with each and every one holding the promise of a future for humanity beyond Earth. For generations, this was a mere dream, as our technology allowed us to neither know what worlds might lie beyond our own Solar System or to reach beyond our planet. But time and development has changed both of those things significantly. Now, when we look to the stars, we know that potentially habitable worlds lurk throughout our galaxy, and our spaceflight capabilities can bring us there. But so far, it would only be a very long, lonely, one-way trip. This isn't necessarily going to be the case forever, though, as physically feasible technology could get humans to another star within a single lifetime, and potentially groundbreaking technology might make the journey almost instantaneous.

      The Forbes link demands that I turn off my ad blocker. Therefore I won't click on it.

      WORKING LINK: http://webcache.googleusercont...

      No matter how much crapware they inject, no matter how aggressively they insist on interfering with ad blockers, sites still MUST be indexable by Google (whose web spiders don't really do javascript) or they might as not even have a web presence...

      So any site, no matter how broken, will invariable look fine in the Google cache. Just do a Google search for the URL prefixed with cache:. That will get you the locally stored version they indexed in the first place. Always a 100% working version of the page, without acquiescing to the site's crazy demands for insecure browser behavior.

      In fact, Forbes should get nailed and demoted by Google for failing to follow the fundamental rule that users must get the same content that web spiders do.

  2. Let me save you reading the entire article by Beck_Neard · · Score: 5, Informative

    1. Generation ships
    2. Nuclear propulsion, antimatter propulsion
    3. Science fiction (warp drives, transporters, etc.)

    Anyway all of this seems moot to me. We can already freeze human beings for long periods of time. It's called 'embryo freezing' and it's commonly used.

  3. Working link to a longer version of the summary by WoodstockJeff · · Score: 5, Informative

    Seems Forbes found out about getting around the clickbaits. The scienceblogs link now just has a longer version of the summary with pictures added, and a link to the clickbait version.
