Cosmological Implications of a Possible Class of Particles Able to Travel Faster than Light

چکیده
Special relativity is usually presented as an intrinsic property of space and time: any material body moves inside a unique minkowskian structure governed by Lorentz transformations. Geometry is also the startpoint of the theory of gravitation in general relativity and provides its ultimate dynamical concept. However, a look to various dynamical systems would suggest a more flexible view with the properties of matter playing the main role. In a two-dimensional galilean space-time, a sine-Gordon soliton of the form:

Abstract ABLE TO TRAVEL FASTER THAN LIGHT
The apparent Lorentz invariance of the laws of physics does not imply that space-time is indeed minkowskian. Matter made of solutions of Lorentz-invariant equations would feel a relativistic space-time even if the actual space-time had a quite different geometry (f.i. a galilean space-time). A typical example is provided by sine-Gordon solitons in a galilean world. A " sub-world " restricted to...
متن کاملApplication of Discrete 3-level Nested Logit Model in Travel Demand Forecasting as an Alternative to Traditional 4-Step Model
This paper aims to introduce a new modelling approach that represents departure time, destination and travel mode choice under a unified framework. Through it, it is possible to overcome shortages of the traditional 4-step model associated with the lack of introducing actual travellers’ behaviours. This objective can be achieved through adopting discrete 3-level Nested Logit model that represen...
متن کاملTime Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملStudy of a Restricted Modified Gravity on astrophysical and cosmological scales
p { margin-bottom: 0in; direction: rtl; text-align: right; }p.ctl { font-size: 12pt; }a:link { color: rgb(0, 0, 255); } In this paper, we study a restricted modified gravity in which diffeomorphism symmetry is broken. We investigate the astrophysical implications of the model by using the corresponding gravitational potential. By using the weight function of the weak lensing , for the model,...
متن کامل“You Travel Faster Alone, but Further Together”: Learning From a Cross Country Research Collaboration From a British Council Newton Fund Grant
Providing universal health coverage (UHC) through better maternal, neonatal, child and adolescent health (MNCAH) can benefit both parties through North–South research collaborations. This paper describes lessons learned from bringing together early career researchers, tutors, consultants and mentors from the United Kingdom, Kenya, and South Africa to work in multi-disciplinary teams in a capaci...
