2D life form can exist with alimentary canal

In summary, there was a discussion about the possibility of a 2D life-form with an alimentary canal, as predicted by Hawking. The conversation then shifted to potential solutions for this issue, such as using movable chainings and designing the chainings to provide structural rigidity. Other ideas were also proposed, such as using different charges and a sticky jelly-like substance. However, it was pointed out that amoebas have already found a solution for this problem in their 3D form.

Hi,
as I read in one of Hawking books, he predicted that a 2D life-form with an alimentary canal can not exist because it would fall apart. I was wondering about that, because I thought of an easy solution for this: with two movable chainings its still possible. I have made a graphic and attached it to this post. In general its a bit off-topic (sorry for that) but I wanted to get some feedback on it.

Your life-form would hinge open at one chaining when the other is open.
What about shaping the canal like a loose-fitting jigsaw-puzzle piece?

To hold together it would still require some structural rigidity.

Yes, but that's only a design issue - you can build / design the chainings strong - maybe they build somehow the backbone of this life form - the graphic should just explain that there exist a way.

You could have lots of them along the canal too ... and you'd need to pay attention to how they hook together.

The two sides of the creature could have different charges ... the canal could be filled with a 2D version of a sticky jelly ... etc etc.

Amoeabas solved that. Just involve the food and push it inside in a sack.

Amoebas are 3D life forms, a "sack" is a 3D container ... OP is talking about 2D.
 

1. Can a 2D life form really exist?

Yes, it is possible for a 2D life form to exist in theory. However, it is currently not known if any 2D life forms exist in our universe.

2. How could a 2D life form have an alimentary canal?

The alimentary canal, or digestive tract, is simply a tube that processes and absorbs nutrients from food. In a 2D life form, this tube would be stretched out along the 2D plane, allowing for the same function as a 3D organism's alimentary canal.

3. Would a 2D life form have the same nutritional needs as a 3D organism?

It is possible that a 2D life form could have different nutritional needs due to their unique physiology. For example, they may absorb nutrients through their entire surface rather than through a specialized digestive tract. However, this is purely speculative as we have not yet discovered any 2D life forms.

4. Could a 2D life form evolve to become 3D?

This is a complex question with no definitive answer. It is possible that a 2D life form could evolve to become 3D, but it would require significant changes in their environment and evolutionary pressures. It is also possible that they could evolve to have 3D-like features while still existing in a 2D plane.

5. How would a 2D life form interact with 3D organisms?

Since we have not yet discovered any 2D life forms, it is difficult to say for certain. However, it is likely that they would interact differently than we do with 3D organisms due to their dimensional differences. They may perceive and communicate in different ways and may not even be able to physically interact with 3D organisms.
