Space time Definition and 159 Threads

Space time question. Before I ask my question I suppose I should ask a preliminary question that will tell me if my actual question has an answer. Does space time only exist in space? If so, is Earth's surface considered space, thereby abiding by space times rules? Also, theoretically if we...

would someone explain to me the concept of space time? i know what it is but am having problems understanding it

Energy---> space time curvature In general energy---> space-time curvature Any sperimental evidence that electromagnetism--->space-time curvature? blue

It is my understanding, that space time is expanding, and that gravitationally bound bodies will stay unaffected by this expansion while unbound bodies will. but is gravity the only force that can overcome this effect? could magnetic or electro static forces hold bodies in station? I do...

It seems unlikely that space time is a lattice because it contradicts the fundamental assumptions and theories in physics. If space-time is a lattice its dimensions are likely to be on the order of the Plank time and distance scales. Opinions?

[FONT=century gothic] To travel in time. It is a great dream . Sorry as my knowledge is poor in this side, to live in younger time or to younger some years by to travel in time. but, in the way to keep good health and to long life time. I know some. Here it is my draft design about the bathe...

hi all, I am confuced. what is space time excatly? -benzun

Is it true that we're traveling through the 4 dimensions of space time at the constant, c? This implies that velocity through the spatial dimensions detracts from our velocity through time and vice versa. For example, if I were traveling at the speed of light, I wouldn't be aging because I...

Hi, I just wanted to know that do u guys think that Multidimensional Space Time can exist. I know the theories can permit this but i am curious to what it would be like in a place having 2/3 D Time matrix. How will onw relate to an event. I also wanted to know that whether any of u guys can...
