A/N: I seen this challenge on Tumblr, write a short fic of how your OTP would spend their last day on Earth. I thought this would be fun to think outside the box and this is what I came up with. Ch1 is for the challenge, Ch2 is the finish the story off for my own sanity.

Sheldon paced his bedroom from end to end, a look of concern spread across his face. He stopped to peer out his bedroom window, it was 9:00PM and instead of the expected darkness the sun shone brighter than it did on most days. Looking down at the sidewalk next to his building he noticed that there was no bustle of people walking by and no cars driving past on the nearby street, everything was eerily quiet. Sheldon wasn't surprised, most people were probably home to spend their last moments on Earth with their loved ones.

"Where is she?"

Sheldon said aimlessly as he looked towards his wrist watch out of pure habit. It was a futile act as his watch along with every other electronic on the planet had stopped working.

Feeling defeated he pulled his curtains closed and laid on his bed. He stared up at the ceiling as he allowed himself to get lost in thought. How foolish were we all, spending our lives in buildings slaving away to pay bills and saving for retirement. We work most of our lives just so one day when were older we can relax and live life, how ironic.

He hated feeling this way, out of control. There was nothing he could do to stop this. There was nothing he could do to stop time and protect the ones he loved. When death knocks on your door it's not going to wait for you to answer.

Sheldon snapped out of thought at the sound of his bedroom door creaking open. He held his breath waiting for the person to appear from the other side. Relief spread through him as he laid eyes upon his girlfriend. He scooted over so Amy could lay beside him.

"How are they?" Sheldon asked with a saddened heart.

"She finally cried herself to sleep, Leonards by her side." Amy tried to say in a reassuring voice.

Earlier across the hall, Sheldon, Leonard and Amy did their best to console a hysterical Penny. They each tried their best to calm her down, but to no avail. In the grand scheme of things it was understandable, they were each scientist except for Penny. Penny couldn't help but be glued to the news footage coming out of NASA. Once the news feeds, cell phone, and internet stopped working Penny grew hysterical wanting to know how they were all going to be saved. But Sheldon, Leonard and Amy knew the ramifications of the data being released from NASA, from a scientific standpoint the inevitable was going to occur and that in less than 24 hours everything around them would cease to exist.

Sheldon's thoughts wandered to his other friends and internally hoped they spent their last few minutes together. Everything had unfolded so quickly, one day your eating Thai food around the coffee table with your friends and the next thing you know 3 of your friends are being picked up by a black ops helicopter to transport them to an undisclosed location.

Howard Wolowitz, Sheldon never said it to his face but he was a mathematical genius. He sailed through the course work at MIT, the government would have been stupid not to recruit him. Then there was his friend Raj the astrophysicist, out of all his friends he was the hopeless romantic of the group. He suppose it made sense, Raj had dedicated his life work studying the stars and the beauty of the cosmos. Then there was Howard's equally small stature wife Bernadette. Bernadette would be damned that Howard and Raj go off to carry the weight of the world without her. Bernadette was one of the toughest people he knew.

Then there was Amy, Sheldon rolled over on his side so he could get a good look at her. She was his beloved and most cherished Amy Farrah Fowler. In the beginning, he prided himself that he was a logical and controlled man. He didn't waste his time with love, his heart was in an impenetrable steel box so he could focus on the important things of life which is the sciences. But then she came along, the only person intelligent enough and determined enough to unlock his heart.

Sheldon allowed himself to relish in the memory of their time together. Meeting her at the coffee shop for the first time under threat of a soiled dirty sock. How they became the best of friends and eventually more than friends. He thought back to the first time he kissed her on the train, how he was taken off guard by the softness of her lips and the feel of her closeness. He thought back to the first time they were intimate together. They had played 3 dimensional chess and she had beat him. Okay, okay, if now was the time to be honest, she spanked him hard at 3D chess. Sheldon had never been beaten so bad when he was in full concentration. That was the moment he realized that Amy was a superior being, intelligent, beautiful, patient… perfect…

Sheldon remember asking her when they were alone one day if she was still interested in an intimate relationship with him. He remembered her answer as if it were yesterday,

"If you'll have me, I'm yours…"

That night he had taken her and made her his. He signed that invisible contract that solidified that Amy Farrah Fowler belonged to Sheldon Lee Cooper. The experience was beyond anything he could have imagined, how beautiful she looked beneath him. The smile that danced across her lips, the blush that streaked across her cheeks when he brought her to ecstasy. He now knew what people meant when they say you can have sex or you can make love, that day he showed Amy how much he loved her. Sheldon didn't necessarily believe in a deity, but on days like that day, sometimes he wondered if Amy was put here just for him.

The sun grew brighter behind the pulled curtains, Sheldon refusing to take his gaze off of Amy asked her,

"Do you have any regrets?"

Amy linked her hand with Sheldon's, "I just don't want to forget everything, this life, what we have together…for it all to just disappear…"

Sheldon wrapped his arms around his girlfriend to comfort her,

"Nothing really disappears, it's just converted to a different form. When you boil water the water doesn't disappear its converted to steam, every 3rd grade scientist knows that."

Amy furrowed her brow unsure where Sheldon was going with this she allowed him to continue,

"Many scientist believe we humans evolved from star dust. The atoms inside us, nitrogen, oxygen, carbon and various other elements that make up the human body are all derived from the stars. So in a sense, were just going back to our earlier form but nevertheless we still exist."

Amy couldn't help but smile back at her boyfriend, "Well when you put it that way, that's really beautiful."

The light in the room continued to grow, Sheldon and Amy had to shut their eyes tight to block out the brightness. Amy wrapped her arms around Sheldon and held him close,

"Do you think in another universe there's another Sheldon whose in love with Amy?"

"In every universe Sheldon Lee Cooper is in love with Amy Farrah Fowler."

Sheldon and Amy pressed their lips together and shared what would be their last kiss on Earth.
