So I've always thought that an increase in velocity of a fluid would decrease pressure. However, I've heard the opposite and that it is an decrease in pressure that increases velocity. All I want to know which one is correct (in terms of something like a venturi pipe) because an decreasing...

3. must show precision.
How could you travel into the future then with time dilation, if time appears slowed for both of them looking at the other body shouldn't time be the same relative to both when one slows down?
I just watched a video that kind of warped my understanding of time dilation. It said that not only would time appear slow from the point of view of someone standing still looking into something going near the speed of light but if you were going near the speed of light things that are...
So if object A and B are going towards each other at .99c and their is one stationary object, the stationary object will seem to be at .99c but object B traveling at .99c towards object A which is going the other way at .99c will seem to be only slightly faster because time is slowed...
So I am trying to understand some of the ideas of relativity but there is one thing i don't get. I understand that if one object were sent at .99 c and from that object another were launched at .99c the object would appear to be at .99c for the moving object but below the speed of light for an...
