Spacetime was combining spatial dimension x, y, and z with a temperal (i.e. Time) dimension t as a points called spacetime events (x, y, z, t); The Lorentz Transformation link space and time together, make it patial unified. Now for the bend or times call a warp in spacetime which developed in The General Theory of Relativity due to the two dimensional trampoline model for gravity as a bend in the trampoline.
This model is inaccurate because space is not two dimensional. If you want to see a three dimension warp in spacetime you can look the video done by discover. The two dimensional terminolgy has stuck around since everyone realizes that the scale of spacetime is actual distorting.
Short answer: Einstein imagined a scientist sealed inside a box. The scientist, and everything else in the box tends to fall toward the "floor." The scientist feels "weight" when he stands on the floor.
Why? Does the scientist feel the force of gravity because the box is resting on the surface of a massive planet? Or is he feeling an inertial force (a.k.a.
, "fictional force") because the box is being pushed through space by a rocket motor? It turns out that there is _no_ experiment that the scientist can do inside the box to tell the difference. Einstein reasoned that if we can't _tell_ the difference, maybe that means there _is_ no difference.
He wondered, how would our understanding of the universe have to change in order for us to imagine gravity and inertia as being the same thing? It took a lot of tricky math, but he found a way to do it. His previous theory required us to stop thinking of space and time as strictly separate things and, to imagine the paths of particles moving through a unified, four-dimensional spacetime.
In order to explain gravity as an inertial force, he now imagined spacetime as a "manifold" that was embedded and curved in an even higher-dimensional space. Just as you feel a "centrifugal force" when you follow a curved path through ordinary 3-D space, you can feel a "gravitational" force when you follow a curved path through spacetime—curved, because of the presence of a nearby massive object.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
