Exploring the Big Bang: 5-Dimensional Bubbles Colliding and Expanding

[Mr Peanut]

Say I have two 5-dimensional bubbles moving towards one another in 5-dimensional space. When they touch, at the monent they touch, they meet at a 3-dimensional "point." As they join, the 4-dimensional hyperplane created their by common boundary immediately inflates from that point and expands.

Is that about right ?

Say I have two 5-dimensional bubbles...in 5-dimensional space...they meet at a 3-dimensional "point."

At first glance, just as two circles meet at an X,Y point (two-dimensional), and two spheres meet at a three-dimensional X,Y,Z point, it seems two 5-dimensional 'bubbles' or any 5-dimensional objects must require a 5-dimensional coordinate to specify a point of intersection.

Perhaps...

The notion of a point is more often an undefined entity in geometry, an axiomatic primitive that has no meaning beyond the intuitive. Any rigorous definition results in a circular arguments.

While a point may be designated with any number of dimensions depending on the space, it alway has a magnitude of zero in every direction. A point on a line and a point on a plane could be seen as equivalent objects.

Back to bubbles. The four diminsenional space arises from the "point." An observer in the 4-D hyperplane at some later time would remark; "the universe spontaneously arose from nothingness."

A point has no dimensions.

As they join, the 4-dimensional hyperplane created their by common boundary immediately inflates from that point and expands.

The way you stated this question was too vague for me to answer what the dimensionality of the intersection would be. However, how two such bubbles interact when they meet depends entirely upon the physics of whatever they are made of.

I find this concept intriguing and it aligns with current theories about the origins of the universe. The idea of 5-dimensional bubbles colliding and expanding can be seen as a possible explanation for the Big Bang, where the universe is believed to have started from a single point and rapidly expanded. The concept of higher dimensions is a fascinating area of study and could potentially provide insights into the nature of our universe. However, it is important to note that this is still a theoretical concept and more research and evidence is needed to fully understand and support it.
