It was late at night as two humans rushed around in a large apartment.

"David!"

"Yes, Alexander?"

"Have we got everything we need?"

"Yes, would you like the list?"

"Give it to me."

"3 months worth of food, portable toilet and shower, a portable dinner table plus two chairs, all portable household appliances, basic plasma weaponry and utility tools, multiple holographic reusable planners, two advanced translators and 4 communication devices, two data pads and independent mobile wifi units, along with all necessary house modules for quick construction."

"Good, and I presume we have extra clothing as well?"

"Yep."

"Ok, switch the portal on."

The two humans were scientists, Alexander had multiple degrees and a very high quality education. David, on the other hand, was more laid back and didn't quite have the same education as Alexander, but was still well educated. The two had been friends for as long as they could remember, as young children they were neighbours, they quickly became friends after a couple of weeks. On top of being neighbours, they went to the same schools up until university.

David had followed Alexander's instruction and had started the portal, he turned around to see Alexander staring at his data pad and quickly checking all the information the portal was sending him.
"All good?"

"So far, yes."

"I may not have your fantastic scientific knowledge, but I sure as hell can build something. Am I right?"

"Yes, David, you can build exceptionally well."

"But of course I couldn't have built it without your help."

"Those calculations may have been a bit hard at times, and I did have some sleepless nights, but in the end, it was you who built it."

"But we make a hell of a team, right?"

"Yes, we do indeed make a hell of a team."

"How long till it's open?"

"A minute, give or take. If it doesn't explode that is."

"Well you should probably record a log entry on this while you have the time."

"Yes, you're right." As he said this, the young man opened his data pad and initiated the personal log application.

*Personal log - Day of destruction - 24th of july, 2047.

Today I activated the portal, built by my good friend David, it should have a dark purple colour and have a swirling pattern visible in it, if my calculations are correct.
The after effects, if there are any, are yet to be researched, as this is the first time we have activated it other than the room to room test two days ago with a smaller test model.
I will attach a schematic of the portal for construction, if it winds up broken, we can fix it.
On top of the schematic, I'll also attached all the necessary calculations for inter-dimension travel, in case this log is found by another being, and they wish to dimension jump like me and David.
If we survive, I will also attach the dimensional code, in case anyone wishes to find us, and the coordinates.

This concludes the log, this is Alexander Jonathan Francis, signing off.

Personal log - conclusion*

After Alexander finished his log, he looked to David, but then noticed that he was looking at the portal, seemingly deep in thought.

"You know, it's funny."

"What's funny?"

"Well, Alexander, when you think about it, we wouldn't have completed this for another couple of years, if we weren't about to die that is."

"You're right. But it's like that with all humans, no one wound have gotten as much done as they have now. Impending doom may mean death is coming, but we get even more than usual done when we're about to die."

"Anyway, I double checked the list." David said, snapping out of his deep thoughts.

"Ah, yes, good. Prepare to venture into the unknown in 30 seconds." Alexander said, also breaking from his thoughts.

(20 Seconds later.)

"10 seconds" Alexander said, looking at his data pad for the timer.
"6" He said again, to ensure he and his friend could count down from five together.

"5" The two said in unison.
"4"
"3"
"2" The pair continued to count down in unison.
"1"
"FORWARD IN TO THE UNKNOWN!!!" They both shouted.

Alexander ran into the portal first, fuelled almost solely by curiosity, closely followed by David.

As the pair was pulled through the portal, they both shared the same, singular thought, which they both chose to express verbally.
"It's been nice living on you Earth, but we gotta go!"

After this, they both hit something, something hard, and they hit it fast.
