I have been doing a lot of regarding about relativistic physics since my earlier posts and I think I now understand the mechanism of the so called cosmic speed limit.
This is how I visualize it.
I know that the ball on a sheet analogy is not perfect but for this I think it will suffice. With that analogy the more mass the ball has the deeper the bowl is created. So as one puts more energy into acceleration the relativistic mass increases which deepens the bowl more due to the action of the gravity on the increased mass. Therefore as you try and approach "c" the well keeps deepening due to relativistic mass increase and so for every unit of energy put into acceleration the bottom of the bowl gets further away and you can never actually reach the bottom of the bowl and start up the other side. That also explains to me why time travel might be possible because with the bowl analogy as the bowl deepens the other side appears to get closer so at intensely high gravities the jump across through a wormhole becomes more possible as the apparent distance between the two sides decreases.
Is this an apt analogy for high speed travel? It also helps me understand time dilation as time is a part of the space time curvature.
Please be kind I am trying to wrap my mind around how to imagine these effects in my mind as real world ideas.
I know I do not have the full knowledge I need but I am getting it and I do appreciate the help and knowledge from the rest of you on here.
Thanks,
