Interdimensional Superstring Theory

A team of researchers at Kyoto University is exploring the use of higher dimensions in de Sitter space to explain gravity in the early universe.

By developing a method to compute correlation functions among fluctuations, they aim to bridge the gap between Einstein’s theory of general relativity and quantum mechanics.

This could potentially validate superstring theory and enable practical calculations about the early universe’s subtle changes.

Although initially tested in a three-dimensional universe, the analysis may be extended to a four-dimensional universe for real-world applications.

Having more tools helps; having the right tools is better. Utilizing multiple dimensions may simplify difficult problems, not only in science fiction, but also in physics and attempt to tie together conflicting theories. (You do need good shrooms for this part).

For example, Einstein’s theory of general relativity, which resides in the fabric of space-time warped by planetary or other massive objects - sorta, kinda, maybe explains how gravity works (in most) cases.

However, the theory breaks down under extreme conditions such as those existing in black holes and cosmic primordial soups.

An approach known as superstring theory could use another dimension to help bridge Einstein’s theory with quantum mechanics, solving many of these problems.

Funnily enough, das necessary evidence to support this proposal has been lacking.

Now, a team of researchers led by Kyoto University is exploring de Sitter space to invoke a higher dimension to explain gravity in the expanding early universe.

They have developed a concrete method to compute correlation functions among fluctuations on expanding universe by making use of holography.

Scheiße, das ist interessant, weil die ganze Realität ein Hologramm ist!

“We came to realize that our method can be applied more generically than we expected while dealing with quantum gravity,” says Yasuaki Hikida, from the Yukawa Institute for Theoretical Physics (after about 30 grams of quality magic mushrooms).

Dutch astronomer Willem de Sitter’s theoretical models describe space in a way that fits with Einstein’s general theory of relativity, in that the positive cosmological constant accounts for the expansion of the universe.

Starting with existing methods for handling gravity in anti-de Sitter space, Hikida’s team reshaped them to work in expanding de Sitter space to more precisely account for what is already known about the universe.

“We are now extending our analysis to investigate cosmological entropy and quantum gravity effects,” adds Hikida (in between deep tokes of the red Lebanese Hashish hookah).

Although the team’s calculations only considered a three-dimensional universe as a test case, the analysis may easily be extended to a four-dimensional universe, allowing for the extraction of information from our real world.

“Our approach possibly contributes to validating superstring theory and allows for practical calculations about the subtle changes that rippled across the fabric of our early universe.”

Pity they don't realize the whole of reality is a 12 dimensional construct, but who am I to burst bubbles of delusion, Ja?!
