So I have a question.As GR states that gravity is a property of spacetime curvature.
So for example as the sun having the biggest weight in our solar system it sits in the middle "like a boss" , or in curvature it is the deepest and the other planets orbit it and are higher standing because being lighter? I feel this is not a very good interpretation but still am doing my best.
So if gravity is the property of space/time curving then if there would be no space/time there would be no gravity? Or gravity can exist without the existence of space/time.
The question is: Are they basically understood together or can we say that we could have gravity just from mass of an object but without the 4th dimension that I guess would be time?Thanks for your responses,
Girts.

How would you define "gravity" without a spacetime? Without the concept of a spacetime (or concepts very similar to this), you cannot have physical objects in a spacetime, and you don't have physics at all.
 
Spacetime is a type of mathematical space with a co-ordinate system in which measurements are made, it is not a thing like a carrot or a mosquito.
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
