What is the concept of Dual Special Relativity?

[Deathless]

Dual Special Relativity.

Read about it briefly and basically forgotten what I've read.
Anyone here care to enlighten me

Thanks in advance

Do you perhaps mean doubly special relativity? I don't get anything that looks relevant when I search for "dual special relativity."

Hmm not sure now.
It could well be Double special relativity.

It is also related to Rainbow gravity - something like that

As Wikipedia notes doubly special relativity is based on the issue of whether Planck length is an invarient length:

If Special Relativity is to hold up exactly to this scale, different observers would observe Quantum Gravity effects at different scales, due to the Lorentz-FitzGerald contraction, in contradiction to the principle that all inertial observers should be able to describe phenomena by the same physical laws...A drawback of the usual doubly special relativity models is that they are valid only at the energy scales where ordinary special relativity is supposed to break down, giving rise to a patchwork relativity...

Hmm.
I never trust Wikepedia in principle but I will have a look at that article as its source might well be accurate. Thanks
