Editing Talk:1158: Rubber Sheet

There is no rope in black hole analogy. On the other hand ... maybe one day this becomes common analogy for explaining some method of [http://en.wikipedia.org/wiki/Faster-than-light FTL] travel ... -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 08:52, 9 January 2013 (UTC)

<strike>It is no rope - it is a rubber sheet seen from the side. Sebastian --[[Special:Contributions/178.26.121.97|178.26.121.97]] 14:01, 9 January 2013 (UTC)</strike>sorry, you meant the rope there ;-) Sebastian --[[Special:Contributions/178.26.121.97|178.26.121.97]] 20:18, 9 January 2013 (UTC)

Did you see the harmonics of the wave? I think there are four different ones in the third frame. Sebastian --[[Special:Contributions/178.26.121.97|178.26.121.97]] 14:01, 9 January 2013 (UTC)

- Two harmonics, two different phases of each. [[Special:Contributions/123.237.156.13|123.237.156.13]] 15:56, 9 January 2013 (UTC)

- Realistically, the forms of the rubber sheet in panels 1-3 and possibly the last are significant. The first and second panels are probably illustrating something interesting related to Catenary curves and behaviour when external force is applied, the 3rd references wave reinforcement, the heavy ball is correctly moving straight up and down as expected under Newton's laws. I don't know if the orientation of the bowling ball, hight relative to how far down it is pulled or the vibrations have formal significance, but a physicist would be wise not to neglect them if they wanted to model the situation properly. The comic overall is clearly showing how a large number of well known effects can occur in a simple thought experiment. The tag line isn't joking when it says there is a lot of physics going on, those shapes aren't being chosen arbitrarily to look good. They are accurate illustrations of the situation being described. A look into the details of what a physicist might imagine, if you will. {{unsigned ip|108.162.249.16}}

It seems to me there should be a cross-reference to [[895: Teaching Physics]] (and if I knew more about the conventions of this wiki I would be bold and add it myself... but I don't, so I won't.) --[[Special:Contributions/67.36.177.100|67.36.177.100]] 17:35, 9 January 2013 (UTC)

I made a playlist of the mentioned "Fun to Imagine" series of videos:

Well I made a rebuttal of Einsdynamics:

Here's a video of a bowling ball being dropped on a trampoline from a height of 165 m (500 ft) https://youtu.be/-6h65t2MOfU?t=623 [[User:The Cat Lady|-- The Cat Lady]] ([[User talk:The Cat Lady|talk]]) 15:39, 22 September 2021 (UTC)
