    Lowest velocity is zero as well. Velocity is simply speed with a direction component associated with it.

    And that direction part is a vector that can have negative components. In one dimension you could have [-c]. So I'm with Chris on this one. Cheers, Drew.

        Hallo Chris, I used the google-dictionary to trnslate 'velocity'. And I got'Einlaufgeschwindigekteit'what means the speed, you inject a liquid to someones ass. Hope, that was not ment:laugh:

          As we know, light speed is the fastest speed we know. But I have a question. What is the most slowly speed we know?

          Albert Einstein had a thought that if you traveled backwards away from a clock faster then light speed you would actually be going back in time as the clock would turn backwards. The same thing is applied to if you see farther into the universe you are actually seeing further back in time as light takes time to travel. So if you equate going back in time to going a negitive velocity in terms of space time, then actually going a faster speed then the speed of light would be slowest. E=mc2 -> BOOM

            Speed or velocity? (Lowest velocity is -c. Lowest speed is 0) cheers, Chris Maunder

                  Relatively speaking, of course. You can't make sweeping generalizations about space and time at those speeds, because you will always find equally correct views of the universe, which contradicts eachother. :)

                      No - it doesn't work like that :) Heisenberg's principle (in part) means dx.dp >= h_bar/2, where dx is uncertainty in position and dp is uncertainty in momentum. If we assume a unit mass then we have dx.dv >=h_bar/2. => dv >= h_bar/(2.dx) (h_bar = planck's constant / pi) So the bigger your uncertainty in exactly where you are, the less your uncertainty about your velocity. So you can say the velocity of an object is as close to 0 as you want. You just have no idea where you left it. cheers, Chris Maunder

                                        It felt like it today! We did Mont Ventoux[^] this morning and while the ascent hurt a little the descent - using the entire road since there was no traffic - was insane. I'm still trying to get the grin off my face. Galibier[^] on Monday. cheers, Chris Maunder

                                          We've done a few 15% and on Tuesday we're doing a stupid 2km, 24.5%. I just look inside for my happy place and hope my knees don't explode. cheers, Chris Maunder
