The scientists are surely not unique in their hypothesis of the cosmos being
a small subset of hyperspace. Membrane theory certainly has not diminished
this possibility, but rather, enhanced the likelihood. The imagined
"difficulties" may be encountered, but so far, there seems little opposition
by proponents of the Standard Model.

Our whole universe may sit on a membrane floating in a
higher-dimensional space. Extra dimensions might explain why
gravity is so weak and could be the key to unifying all the forces
of nature.
The main problem is that it is just a few years into this research
program, so they haven't had much time to find problems with it,
and this article is written by its advocates, who may not be telling
about all the problems.
