"But, Mr O'Donnell, why is it important?" Miss Chaisson first said, daring to break the silence. "Dimensions are always a concept too far-fetched, and I think you know that well."

"Miss Chaisson, please let me explain. This theory, it's," he stopped short for a moment, giving a quick look at his folder before clearing his throat nervously, "it's not a lot. But, given the present situation, maybe it can prove worth your time."

"Okay, then," Mr Smith said, stepping away from his place by the board. After asking, the man carefully opened the laptop and in a moment, the Shorts video popped up.

It played down to the last video frame, where, although blurry, a thing which looked like a city hall clearly appeared in blue light.

"First I may inform you of what I define as "another dimension". Another dimension is a reference point in space, with characteristic geometrical properties (be it of known or higher dimensions), the properties of which don't change according to the position of the observer, behaving somewhat like a closed vacuum in the macroscopic plane. Now, I'll get to the main part."

The man started to pace around the room.

"Time," he began, "is a concept we're all familiar with in this room. We're physicists, so to speak! But at the same time, we know absolutely nothing about it," he said.

He stepped towards the board, and grabbed a chalk eraser, clearing a small part of the extensive equations.

"If I explain to you the Lorentz transformations, you might first think I'm mad since you've all spent years operating on such concepts. Yet let's remember that we can calculate time dilation, we can use it to create approximations of what light looks like, and we can, at most, predict the Big Bang or Big Rip, et cetera, et cetera, but do we know any properties of time itself? How does our knowledge help us to understand time? How can we predict it, when we only know which way it runs on the clock, which is, too, an object of speculation? It seems like we're a bunch of cats with our eyes fixed on the meat, when we should be investigating the barbecue stick on which the meat is set," with that, he drew a horizontal line. "And I'm not gonna draw a barbecue stick here."

Meddles lowered his eyes.

"If time is a parameter," he wrote a t on top of the line, "it has to be dependent on something. And if it's not, it has to be a constant," he drew a not equal symbol and a C next to the t, "which it isn't. Now please inspect my derivation as I carry on talking," he started writing some physics equations on the board. "We have time, right, and some x. A variable on which time depends. The closest thing to time and the definition of which solely depends on it and the force by which it is caused is velocity, or V. Velocity is fundamental. We all know. But what if velocity wasn't so fundamental? As it shows here," he pointed to a tensor equation, "it doesn't account for a velocity variable to be included in the equation. But if we change time, we may have a bit of a problem here," he paused.

Meddles raised his hand.

"But Led, the thing is here, we see time depends on the course of events, which are all labeled as k goes from zero to infinity, or from zero to t," he nervously said, but his eyes sparkled with enthusiasm. "Time depends on the number of events. The number of events that have happened before today, is, of course, gigantic."

"Five hundred quadrillion events, if not more," Mills worriedly added. He raised his hand a little (not as much as to crease his suit) to point out the equation. "But in this derivation, we get a hundred decillion events. Which is much, much more!"

Led O'Donnell didn't hesitate to reply.

"From that load of events, we get to something big that could have the same number of events. Something gigantic. Something that could only be defined as... another Universe," he said, quietly, but not without passion. The hand continued working.

"If I'm not mistaken, that universe can pass, at some point in time, right through our own, creating an area of geometrical deviation, or a "time-skip" to one single event that has already passed. This way, with the necessary alterations, even a past event can still exist in the present, or future. I guess what I'm trying to say is... that the city we have seen, on the 1st of April, underwater, may be a direct replica of a past-time event which happened any time in that same place before the present. It may have happened six years ago, it may have happened a billion ago, but, the point of this all is," he finished writing the derivation and underlined the formula. He turned to the silent scientists.

"That this thing, here," he pointed with his marker at the laptop,

That this thing, here, may be an entrance into another dimension."
