Quoting: Anonymous Coward 1384172 Take a look at this table, if you like 'warp drives' idea: [link to i.imgur.com] that was pretty cool thanks! |

Anonymous Coward User ID: 1410622 United States 08/22/2011 05:27 PM Report Abusive Post Report Copyright Violation | Voyager 1 is NOT current technology. Quoting: Dr. House We have ion drive now, and the ability to scoop matter from interstellar space. [link to en.wikipedia.org] Using an Ion drive coupled with a fusion reactor, means one can see at least 30 years of continued acceleration. Even if you have an acceleration of only 0.05 meters per second, over 15 years (473040000 seconds) your final velocity is 23,652,000 meter/second. The speed of light is 299,792,458 m/s You are traveling at about 8% the speed of light. Granted that isn't very fast, but in order to travel 4 light years it would only take 50 to 100 years. It is feasible to construct a ship that can accelerate at 0.3 gee (3.33 m/s) using current ion engine technologies coupled with tapping the thermal differential of natural space. Boosting constantly for only 2 years (63072000 seconds) Means you would achieve a velocity of 210,029,760 m/s That is 70.0583% the speed of light. Assuming for the moment that relativity does not play a roll in the matter, it would take rough a decade (10 years) of accelerations, coasting at top speed and deceleration to reach the nearest star. NASA and JPL and the rest make it much harder than it needs to be. Even Einstein made a minor mistake that every one else follows through. Einstein tells us that near light speed is not possible because mass (of the craft) becomes greater due to speed. however E=mc^2 (Energy = mass times the speed of light squared) gives us more energy from a mass of matter traveling at greater velocities - why? because the fuel attains a higher mass as well as the craft. Relative to each other, the mass of the craft to the fuel remains the same. Relative to the rest of the universe the mass of the craft and the fuel increases. The fuel gives out more energy relative to the universe due to its greater velocity. We cannot accept that mass increases as we travel at relativistic velocities without accepting that the energy strips from that more massive matter also increases due to more mass.

The problem is right now we can convert about 0.0001% of a fissionable material into energy. Fusion isn't much better, and we have no means of controling Nuclear Fusion currently, much less turning it directly into kinetic energy. Now if you have a Matter to Kinetic Energy Converter, hell, yes, we can do this. Oh, your calculations about the ion drive, while optimistic, are not far off. An ion drive is by far the most fuel effective engine we have. Since that thing can fire for years without slowing down, if you follow the gravity contours of Space-time, you can get some major speed doing. Going faster then 10% the speed of light starts to get weird. It isn't just interstellar dust that's a problem, but when you start to get up to relativistic speeds, even light photons can ruin your day. If you see something, say nothing, and drink to forget.
