Imagine a donut with a hole in the middle.  The doughnut is infinitely large - the dough, at it's thinnest point along its round curve, is infinite, and the hole in the center of the donut in infinite.  Now, if you'll excuse the hangriness of this example, the infinite size of the dough of the doughnut is infinitely than the infinite larger than the size of the hole in the middle of the doughnut.  Thus, the hole in the doughnut cannot exist as the doughnut's dough takes up all of infinity, but the hole in the doughnut is also infinitely large.  Infinitely tiny and infinitely large at the same time.  This may prove the idea that a negative infinity is the same as a positive infinity.

Eternity is weird.

The grandfather paradox and does free will exist.

If you go back in time and kill your grandfather you won’t exist right it would depending on which you believe

1. Time stops you can’t kill your grandfather without killing yourself indirectly thus time can’t work.

2. Split timelines a time line where you didn’t and where you did kill him you just traveled to the one where you did.

3. It was accounted for. The person you killed wasn’t your biological grandfather which let’s you kill him without removing your self as well. Has the side effects of making free will an illusion.

 Now that leads into an interesting discussion about time travel. I know this is the paradox cult, yes. But this includes a paradox. There are two theories I have. I can't prove any of them without a time machine.

1. You're "protected" in the past. If you go back in time and do something to prevent your existence, you'll still exist. Everything else will change except people protected by this.

2. You're not. If you go back in time and do something to prevent your existence, you'll stop existing, so you could not do that thing to prevent your existence, so you'd exist, etc. Therefore, it is impossible to change the past.

 I once read a theory where the only form of time travel is to travel to alternate realities in a different time frame than us. (Think ITSV, but waaaay less variance in the physical world) So let's say on this earth it happens to be Tuesday, 2:00. If you traveled back in time to Tuesday, 1:00 and killed yourself, you would still exist in your own time frame because that was a completely different you. Thus, killing your grandfather back in time would have about as much effect as killing Peter B.'s grandfather rather than your own. A completely different you would fail to be born. 

 This is my personal favourite.  Where universes split.  I also think such noted individuals such as Noah were visited by time travelers and mistook them for gods due to tech advances.

 Is it weird that I kind of understood this?

Oh,  this is back!
