Of course you can, what is nearer to you from a point, a cave, or a dome? The dome is nearer than the cave, so in terms of location you can't have the cave positive, and the dome negative. Negative numbers attract, so science has a positive mass electron, it throws out Quantum physics. Science has no attracting mass. Science treats the electron as a sphere, but it is a hole. It is full of gravity... which makes it spherical. Without the negative number, how would you know that the electron is full of gravity?
The reference of a point, a cave, and a dome makes no sense either! It almost sounds like you are confusing math (negative numbers) and a vacuum (void).
And how are electrons "full of gravity"? Are you talking about nuclear forces now? Atomic bonds? You are jumping everywhere...
