Flat spacetime has zero curvature i.e. it's geometry is Euclidean. In Euclidean spacetime, angles in a triangle always add up to 180

Why Cathode rays travel in straight lines?
They don't. Well, they do in flat spacetime in the absence of an external force, but it's not a peculiar property of cathode rays; everything does that.
How does mass effect gravitational force?
There is no such thing as gravitational force. Mass curves spacetime and stuff moves through spacetime in straight spacetime paths. The effect of this is what we call gravity. The more the mass the greater the curvature of spacetime.
Does gravity have an affect on photons?
Gravity deforms spacetime, and photons follow the curves in spacetime that are put there by objects with large mass (and, therefore, large gravity).
Does time move in a straight line excluding spacetime gravity changes or in a wave and if a wave do you travel on the wave or through it?
In the geometric treatment of spacetime, time is a linear dimension. A given particle could have a straight or curved track in spacetime, but time itself is a straight line.
What is the definition of plane of application?
A plane of application is an imaginary, flat surface in which an applied force passes through.
Is universe curved?
Basically, we don't know if spacetime is overall flat, or overall curved, nor if it's curved HOW it's curved.
What is the artistic definition of a flat sketch?
the artistc definition of a flat sketch is a sketch that is not really 3D
When was Spacetime Studios created?
Spacetime Studios was created in 2005.
Is gravity a force or a bend in spacetime?
Gravity is a force, not a bend in spacetime.
Why Cathode rays travel in straight lines?
They don't. Well, they do in flat spacetime in the absence of an external force, but it's not a peculiar property of cathode rays; everything does that.
Does all mass warp spacetime or does the warping of spacetime start when mass reaches a certain level?
Look at this websitewww.spacetimemodel.com It says that mass is really just a 4d volume of spacetime displacing and therefore warping the spacetime around it and so the answer is all mass displaces and so warps spacetime.
When was SpaceTime - software - created?
SpaceTime - software - was created on 2007-06-04.

What is the definition of 2d drawing?
the definition of 2D is it is flat on the piece of paper -A design
Does a polygon have a flat surface why?
Yes, because a polygon is a plane (flat) figure. By definition, if it is not flat, it cannot be a polygon.
What is the definition of the flat layer of the skin?
the flat layor of skin means on your body all of the flat bit of your skin!
How does time effect space?
Time doesn't affect space. Space and time are the same thing in relativity; that's why we call it spacetime. Mass affects spacetime and spacetime affects mass.
