I was watching posts about mass affecting space-time and things like that,and i found a variety of answers,but i didnt saw anyone explaining it totaly.
So by my opinion best explanation for this is:if we imagine a space like a trampoline that has no middle part.When we drop heavy object like bowling ball it bends trampoline and all the small balls fall to the recess what the big ball made.But if they have speed they wont fall closer to the middle.But why does the light curves? Well again imagine trampoline and bowling ball,and put a laser at the flat part of trampoline.Beam wont follow the hollow,but to
the object that is in the hollow it is going to look like the beam has curved,while it remained straight.My conclusion:light beam stays flat,and objects are irregular.
Sorry for grammar!
Whats your opinion?
