technically this is right AND wrong
because everything pictured in your screen had already existed
so its all past
if you can really look at the future on screen, it would be blank
Consume too much coffee, time both speeds up and slows down simultaneously.
you feel a sense of cosmic cold and then you pass out and wake up two days ago.
Lol and your avatar is a dude with a huge fist for a head, so surreal

In two days tomorrow will be yesterday.
No, that line WAS the present.
Trying to visualize more than 3 spacial demensions is definitely a mindfuck.
...
Also if our Universe has a beginning, what came before? Mindfuck.
Time was created at the brith of the Universe? Mindfuck.
...
Visualizing existence (if it can be called that) without time? Mindfuck.
...
Has the Universe always existed? Mindfuck.
...Similarly, if you had someone living in a plane, and wanted to show him a sphere (imagine pushing a ball through a piece of paper), you'd repeat this process and he'd see a point that turned into a circle that grew, then shrunk, then collapsed back to a single point and disappeared.
What would happen, then, if someone four-dimensional wanted to do this to us? We'd first see a point (you get the idea that a point is a degenerate n-sphere - not particularly useful, stuck with radius 0, but the most obvious such degenerate), then it would start to grow as a sphere, then stop growing and start shrinking, come back to a point, and then vanish.
Spheres are too easy, to be honest - far too much symmetry for anyone's good. If you imagined a hypercube, there are many ways that it could pop into existence - if the four dimensional thing 'passed it through' properly, we'd simply see nothing, then a cube, and then nothing again. For the rest... to hell with that, use a calculator and leave me out of it. For a triangle, in one configuration you'd see a point, then a growing triangle, and then all of a sudden the entire thing would disappear.
What's the point of this mess? Get used to viewing three-dimensional objects that vary with time, and you'll start to see four-dimensional objects just as easily...

Imagine explaining any of this shit to an ant.
Perhaps we are that ant to another creature.
I've heard similar explanations before, and while they definitely help to explain the concept, is the example not still merely a 3 dimensional representation of what we would expect to see of a 4 dimensional object in our 3 dimensional world? I've also heard the "worm maneuvering an extra hidden dimension on a tightrope viewed from afar" example, which also makes perfect sense (Though I like your example much better) but for a mere mortal such as myself, visualizing a 4 (or more) spacial dimensional world is still a mindfuck.
Since my original post I've put more thought into some of the other questions I posted about time and I concede that they are pretty rediculous, as you've pointed out. Before the Universe there was nowhere, and "no-when", so to speak in terms like "before"/"after" or the Universe being "inside" something seems a bit irrelevant.
I appreciate the knowledgable insight from someone who knows probably infinitely more about these things. It's like adding lube to the mindfuck.
EDIT: Something kind of weird that I just considered that probably has nothing to do with actual physics: There's always talk about extra spacial dimensions, and although space is considered just one part of "spacetime", what of the idea of other dimensions that aren't spacial dimensions, but are more like the time dimension (superficially separate from the spacial dimensions), but we have no perception of them? I guess mathematics would have suggested their possibility by now.
I'm way out of my league here and don't really know what I'm talking about, obviously.
It is exactly this line of reasoning that allows me to hold on to my Agnosticism.
Wait, you're agnostics because there might be something incomprehensibly smarter than you? Yeah, I can see that ending well...
