**PREFACE**

While explaining multidimensional rendering to a friend online and studying conic sections, a thought came through my head. If you sliced a 4 dimensional cone with a 3 dimensional plane, would you be able to create any regular manifold? Trying to picture this in my head, I came up with this example to visualize the 4th dimension involving a pair of ghosts. These ghosts cannot see or interact with each other in any way. As a scientific ghost, one of them might say "two ghosts cannot occupy the same space at the same time; that's just not possible.". Of course, while he's saying this, you are looking at him stand inside of the other ghost. Well, in a way, he's correct. The thing is that each ghost is existing in it's own space, shared by a space of greater dimension. If you stacked a bunch of pieces of paper neatly on top of each other; each with a red dot in the exact same location; it can be said that the red dots are all occupying the same 2d space.

Then I asked myself, "what would it look like to move through the 4th dimension?". Imagine 3 ghost cubes of different sizes, all occupying the same 3d space via the 4th dimension, and that you can only see one at a time. First, you see the largest cube. Then you move one unit through the 4th dimension and you see the medium sized cube. Then you move one more unit and you see the smallest cube. By moving through 4 dimensions, you perceive that the 3 dimensional object is changing. If such is the case, then couldn't the movement of **everything** in the universe be redefined in terms of it's velocity across the 4th dimensional axis? And furthermore, couldn't what we call time be just a measurement of distance from one point in 4 dimensional space to another? If so, then the equation for acceleration; **a=d/t**; could be redefined as **aₓ₋₁=d₀…ₓ₋₁/dₓ**; where 'x' is the number of dimensions. At the very least, this statement is geometrically true.

**EXPLANATION FOR GRAVITY**

Imagine that you shoot a bullet through a few very thin layers of plywood, where each layer represents a separate 2 dimensional space within 3 dimensional space. As the bullet is passing through the wood, it will be exerting a force on each layer in both the X and Y directions relative to the size and speed of the bullet. The hole it leaves behind makes this clear as day. Well, according to Newton's laws of motion, for every action, there is an equal and opposite reaction. So, the bullet will have an equal amount of force exerted on it relative to the 2d plane of the wood. So, logically speaking, if a 4 dimensional bullet was shot through our ghost cubes, would the bullet not have a force exerted upon it in 3 dimensions? And because the amount of force required to accelerate an object is dependent upon it's mass; time would actually move slower for objects with greater mass. And this leads to something even more interesting...

**BLACK HOLES WITHOUT HAWKING RADIATION**

As is well known, energy cannot be created nor destroyed. However, what would happen if an object's mass became so great that it's relative time practically stopped? Well, for the rest of the universe that's still moving, the energy will seem to have vanished. We're riding the bullet that went through a few more boards than the other bullet and asking, "where'd the other bullet go?". Well, the bullet didn't just turn to dust and keep going through the board with us. It's way back there; stuck. In laymen's terms, a black hole would be where time slows to a stop; not a /dev/null of the universe or a giant wood chipper.

**HOW THE FUTURE AFFECTS THE PAST**

With a black hole being redefined, we can now more easily ponder about what would happen if you entered (and left) a black hole. The first thing we'd have to realize is that once we enter it, there's no coming back out. At least not in the same 3d space as we were on before. To do that, we would actually have to be moving even faster through the 4th dimension than what we were to both escape and catch up; then practically hop onto a speeding train. Even getting close to a black hole would drastically reduce the amount of force being exerted on you across the 4th dimensional axis and permanently set you a few moments in the past. So, once you're inside, your only option would be to exit the black hole at an angle. And when you do, your perception of time would only continue due to your own momentum as you would now exist in a universe of 4d bullet holes. You would not be able to see or hear anything. And even if you could, you wouldn't be able to interact with it. The damage is already done in the future, so all you can do is watch from the past. This may seem like a stretch, but there was actually a team of physicists at a university in Australia that recently proved that; on a quantum level; the future affects the past. Additionally, this would make any temporal paradoxes stemming from violation of causality impossible.

**SUMMARY**

Simply by factoring 4 dimensional movement into the equation, a lot of the puzzling problems in physics go away; and at least as far as I can tell, it doesn't require changing any of our current understandings aside from Hawking radiation which is still inconclusive.
