So far as we know, our dimensions are infinite. So it's not really possible for other dimensions to be "larger".keepitmoving said:would string theory work if some of the extra dimensions were "larger" dimensions than our dimensions? In other words our visible dimensions would be the "Calabi Yau" dimensions of the larger dimensions universe.
I don't quite see how this overcomes my objection.keepitmoving said:maybe i used the word "larger" in a wrong way. I was referring to our visible dimensions being larger than the Calabi Yau dimensions and supposing that our visible dimensions might be embedded in "larger" dimensions.
Yes, but if our three spatial dimensions are infinite, how would any others be larger?keepitmoving said:just to be clear, i`m trying to understand, not overcome your objection. I`m here to learn.
I`m using the word larger to describe a series of larger and larger Calabi Yau spaces (dimensions).
I don't mind being a bit argumentative. I just don't understand what you're saying. What do you mean by larger?keepitmoving said:i hope i don`t sound argumentative here!
I guess i`m using the word "larger" in the same sense that our visible dimensions are larger than the Calabi Yau spaces (by the way, are the calabi Yau spaces infinite?). In that sense could our visible dimensions be someone else`s Calabi Yau dimensions?
There are two ways in which we currently are aware that these extra dimensions might potentially exist, but still be consistent with the fact that we don't observe them.keepitmoving said:i guess i`m using the word "larger" wrong.
Could our visible dimensions be inaccessible to creatures in a world of dimensions other than the Calabi Yau dimensions? Could what`s going on in our dimensions be analogous to the strings doing things in the Calabi Yau spaces?
Extra-dimensional universes are hypothetical universes that exist beyond our three-dimensional space. They could have extra dimensions, such as the fourth dimension of time, or even more complex dimensions that we cannot even imagine.
Scientists use mathematical models and theories, such as string theory and M-theory, to explore the possibilities of extra-dimensional universes. They also conduct experiments using high-energy particle accelerators to try and observe evidence of extra dimensions.
At this point, it is purely speculative whether humans will ever be able to physically travel to extra-dimensional universes. Some theories suggest that it may be possible through advanced technology or by manipulating gravitational forces, but more research is needed to fully understand the nature of these universes.
As with any scientific exploration, there are always potential dangers. However, the specific dangers of exploring extra-dimensional universes are unknown since we do not fully understand their nature. It is important for scientists to carefully consider the potential risks and take necessary precautions in their research.
The idea of extra-dimensional universes challenges our traditional understanding of the universe and opens up new possibilities for the laws of physics and the nature of reality. It also raises philosophical and existential questions about the nature of our own existence and place in the universe.
