Ranger

 As the Ranger splits off the endurance, Ranger starts heating up while entering the thick atmosphere of stelleris, there was no-way back, crew of two got panicked named Raghav and Safeer, they tried controlling Ranger but due to high speed winds fluttering through its wings made the Ranger unbalanced.

After a while...

Raghav toggled RCS thrusters which made Ranger aerodynamically stable and flew round and round above the icy surface of the stelleris, the crew landed the Ranger down on the surface of stelleris smoothly. 

There was nothing down there, the whole planet was covered by thick icy sheets leading to nowhere (the planet was the size of Jupiter).

They were walking on the planet for the first time outside Milky - way (enormous feeling isn't it). Meanwhile a strange burning spaceship with tons of smoke swirling in the atmosphere made both freaked out, it was none other than an alien spaceship coming towards them, they felt like it's going to kill them, but unknown entities made their craft landed on the icy sheets, they ran to the Ranger and entered it, Raghav toggled the Ranger but it didn't. He said 

Raghav: Wo!!! Wo!! Listen up, why this stupid machine is not starting up, what kinda problem with it? 

Safeer: that's a sort of anamaly, entities crashed the software, I guess.

Raghav: that could be a serious issue if you're correct.

Safeer: it is, believe me!

Raghav: I guess the same!!

Safeer: So! What's next?

Raghav: they gonna kill us, and that is for sure, there's literally no way back! 

Safeer: start up the engines

Raghav: I can't, radio waves emitting from unknown craft has destroyed impulses, can't do anything

Safeer: oh no!!! That was unexpected, what do we do now?

Raghav: tries!!!

They were stepping down from their spacecraft, they looked huge with an ugly looking eyes, and they were talking with eachother in an unknown language.

Entities saw Raghav and Safeer but they couldn't be able to move, they were utterly shocked by their appearance. One of the aliens displayed his hand and boom, everything flashed into a white light, Raghav and Safeer were unconscious and were swirling around the orbit of stelleris as they opened their eyes, they saw endurance (space-station orbiting stelleris), it was about 400 metres away from them, they didn't had any idea what did just happened to them, Raghav came up with an idea that why not they must use thrusters on their suits (not a bad idea, can't they become iron man, just kidding) they had a little amount of thrust fuel left and the oxygen was getting itself down, they were panicked but somehow they managed their passage towards station, it was hard (managing fuel, then giving a thrust)

They entered the endurance and soon as they stepped in, endurance converted into a 5th dimensional tesseract which was infinite and it went nowhere, they could be able to see the time physical, time when they were down on the icy surface of stelleris, they saw that the hand of the entity by which everything turned into a white light actually bended the space time fabric and dilated the time (time dilation), which they felt later on in the emptiness of the space. As soon as they understood the tesseract, it got vanished at the end of the white light occurance, everything turned into non-existing reality, they felt like it's an anamaly, it was a parallel universe actually, they voyaged through the space time fabric via Einstein-Rosen bridge (wormhole), it was a whole different universe, everything was opposite to what they felt in their universe, time flowed backwards, time was physical which means 4th dimension was a physical dimension there, people looked strange, no-one looked at them or talked, they all were walking down the street which lead to the end of the universe...
