3D image of gravity contest

The concept of space 'bending' comes from the 2D example of two balls on a stretched out fabric. A top view of the experiment shows a different view and looks like the image in this video.


The other 3D example of gravity popular on the internet is in the attachments. Which do you guys like better and why?

Please explain your logic behind this deduction.

Sure with this poem

A gravity A day

One day
kryptid say
'A VISUAL ANALOGY,
end of day.'
then he put on
his sunglasses
to block
gravitational waves
and spins out of the room
saying 'good day'
but knocks down
his coffee
and exclaims 'wait!'
'gravity is
like forum guy say?'
the end
good day

Hi.
I will watch the video this time  BUT  could I put in a personal request:

Describe the nature of that link if you can.   I don't like clicking on anything I can't understand.
This thing is a YT video   and not some executable file that will damage my PC, I hope.
Can I get the choice to find this video on YT directly please?  Can we see how many views you've already had and/or make an informed choice about whether you are just trying to boost the revenue that YT will pay you for extra views etc.
I'm sure this case is quite genuine and you just want some opinions but you can see why it's grey area.   People who genuinely want some discussion will spend some time discussing the issue in ordinary text in their post.

I'm counting that as spam. Please don't do that anymore.

Hi again.

OK, I've seen it now.
    You start off with this comment   "A quark is a particle of extremely dense space time".

I don't recognise space-time as a substance or thing that quarks can be made of.  You could try to re-define space-time in this way but you probably need a video just for that.  I'm not sure if this "competition" you speak of will allow you to define space-time in a way of your own choosing.  This is the generally accepted idea of what spacetime is:
In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold.     [Taken from Wikipedia]

The video is also un-necessary.  There is nothing in it that couldn't be presented with static and flat media such as an ordinary book with a diagram and writing.  The on-line equivalent of this would be a static web-page.  There's really no need for audio-visual media to have been used.

I don't understand what the purpose of the image or video is.  It doesn't seem to be a 3-D image of gravity as described in your title.

It's always easier to criticise than to create.  I'm sure I couldn't have made anything like that and it has some genuinely good ideas.  I think your main point is that matter causes gravity.  That's certainly good enough for school.  You have not provided us with any guidance about the nature of this competition or the average age of those who enter it or watch the final product.  I'm guessing that they need to be old enough to know what a quark is and they are seeking some visual representation for the curvature of spacetime.

Stop spamming. Bored Chemist hasn't even replied to this thread. Do I need to suspend you for a few days?
