You Think 100 Miles Per Hour Is Fast, Check This Out!...

This is a fast as you can get, best of all, we could, (if reliable rocket engines could be developed) use this to have a guided tour around our solar system within a few months!

P.S. the second video has the end to the first one!

    Pretty cool! You better hope you don't have to stop fast or make a sharp turn.

    Just when you think you've got it all figured out, someone changes the rules.

      It would probably take years to put on the brakes or reverse the engines.

      The probe going to Pluto, is doing 15,000 km's a second, and it will take about 15 years to reach Pluto, (all up) but of course it has to use gravity assist from Jupiter, etc to pick up speed.

      The ship in Avatar, did about 110,000 km's a second, (one third light speed) to arrive at Pandoora, a few light years away almost 6 years later, although as some people has said, the ship isn't realistic or plausible!

    One thing that they never really said in scifi movies, though sometime they seem to alude to it, is that you would have to have a computer that processed billions of billions of instructions per second. It would have to be able to clearly see things millions of miles away, and be able to determine EXACTLY how fast everything went and would be going, etc.... You would have to lay in the course, and have the COMPUTER do the driving. I mean THINK about it! Let's say a meteor is coming down, if your plan is off, you could hit it.

    Going at the speed of light is theoretically impossible. If you could do it, we would have to reconsider how atoms even exist. So if you have to have reverse engines, you would effectively cut the potential speed in half. But how else could you stop?

    BTW making the ship large is NOT the answer!!!! SURE, you would have more fuel, but it would weigh SO much. THAT is why they have multi stage rockets. They have the fuel to get the inertia up, and get them past some of the major pull, and drop off which leaves them lighter so the next stage can have a better efficiency and build on the accelleration. Eventually, the ship is not very fast on its own but takes advantage of inertia and the low gravity.

    I mean 100 MPH is NOT very fast, but you DON'T wan to drive that fast unless you have a clear view of the road or EVERYONE ELSE is driving that fast. And 3MPH is not that fast either. Most bumpers can handle it. Hit a car with each of you moving together at 3MPH, and you could have some damage.

      Hmmmmmm, computers probably could cope with it, eventually, quantum computers will be able to achieve processing speeds that we can barely comprehend.

      But as for your other points, unfortunately you have a point, the video below shows how impractical the Avatar ship is...

    IF we sometimes will be able to travel in the speed of light, we need to have some serious "shields" around the spacecrafts because the kinetic energy that will occur if we hit a dust particle or even a single atom in the speed of light (300,000 km/s) will be much greater than all the nuclear bombs that have been detonaded on earth in the history.

      But what would the shild be made out of? No known material or energy could cope.

        I have no idea. But the scientists are currently researching on a material that's called "nanotubes" which is a incredible strong material. It has the same, strong molecular structure as a diamond except it's flexible.

        But if we someday get the technology to travel at the speed of light, I'm sure we'll have the technology to create "shields" that can recist the kinetic energy from impacts with particles at the speed of light also!

          Still based on atoms! 8-(
