Crazy pool vortex

This unique phenomenon can be easily reproduced in a pool on a sunny day.

​@liquid klone he ain't the bicycle NINJA for no reason.
also, praise be unto his meatballs.

and no, life is not a well-defined term in science, neither are consciousness or existence. for that matter, science can't tell you why pi is a certain precise irrational number, nor why infinity is infinite. some things are definitional.

Just because we haven't been able to produce life with purely inorganic material yet, doesn't mean that we can't.

Dude organic implies that it comes naturally from living things. What else would it come from if not inorganic things

It's the secret to creating wormholes! All we need is a 4 dimensional plate and we can make a tunnel through the fabric of space and time!

Danny Hoberman - 2020-01-16

Except that the fourth dimension is time and you can't have time as a dimension in your "4d plate".
Also, we need two media (one being the fabric of space-time) for this kind of an arrangement, and last I checked our universe has only one.
But the Idea is still open to future discoveries.

charles joshi - 2020-01-16

@Danny Hoberman thanks for the explanation 😊

Samar Singh - 2020-02-08

but i don't think you will be able to find negative energy in your garage.

Samar Singh - 2020-02-08

@john noe to be more precise the curvatures required to create a wormhole can not be created using the normal energy we deal with. It requires a different type of energy called the negative energy to create a curvature in the fabric of space-time for connecting to distant points in space as well as time.

Scott J. - 2020-02-24

It's already been done. They just keep coming back in time and foiling our efforts to reinvent the process. :)

Alex Contreras - 2016-12-03

What if black holes are just vortexs

It's the fox! - 2019-06-11

@Cat Poke you are seriously confusing the erm theory with hypothesis

Tharanga Madhusankha - 2019-07-02

They are

Mikkel Højbak - 2019-08-24

According to theory, they are! Rotating black holes make a Ring Singularity when they collapse - and since nothing will have "no rotation" forever, they all have some non-zero radius. It's a 0 volume vortex, basically.
For more info, see this: https://en.wikipedia.org/wiki/Ring_singularity

Mr Hole - 2019-09-07

this explains quantum entanglement and why they have opposite spin..


entangled particles are actually the SAME higher dimensional object!! (that intersects this dimension.)



we are therefore the "shadow" of a higher dimensional reality.

Anshul Tiwari - 2020-06-06

They are infact a vortex of spacetime.

Wow, apart from the 2 connected vortices, I always love seeing the green graduated frog... And her of course.

This flow pattern is like magnetic field. you know, instead of the plate imagine a magnet.

Wait is "physicing " a word …?

shashank soni - 2016-10-09

Can we make a connection of wormhole with this?

Imaginary Universe - 2019-03-14

Apparently until it contacts a boundary of a different medium, water through water, air through air, space through space. I think space is where the greatest potential is and the question is how exactly to create the vortex. I think the answer can be seen in Giza but I don't know if it can be understood exactly. It seems to work as the electron transfer chain in our mitochondria most apparently with the slabs above the King's chamber resonating as the enzymes that attract the electrons in our cells. It may sound crazy but I am pretty sure it's correct.
