"The first forty three parallel universes I've checked proved to be empty. I see no reason to suspect universe number forty-four will be any different." Sheldon recorded his verbal journal as he looked at the wormhole that he'd just created. It looked like a large shiny blue ring with a white outline.

This creation took several months of going to the basement at two forty-five each day, to keep it secret, and after working out the appropriate mathematics he managed to build a machine which generated a 'wormhole'. He felt his heart pump excitedly as he saw the wormhole appear before him for the first time. However Sheldon realised he had to test and perform scientific experiments on it and he didn't know how as he had no idea what could be the other end of the hole. He avoided doing experiments on it for a week until his scientific curiosity got the best of him and he touched the wormhole. He found objects and then his hand go into it quite easily and safely. He put on an oxygen mask and put his head into the hole. It was blue nothingness and reminded him of a lifeless ocean. He tethered himself to the room and bravely stepped inside for the first time. He found himself walking on nothing which seemed odd. He continued to walk but it was still nothing and he eventually came back to where he started. Each day he did another test and so far the result was the same, walking aimlessly in this wormhole and ending up back to the basement. If this continued to happen Sheldon would just have to give up. What was the point of his discovery if no one could use it?

Sheldon took a deep breath stepped into the large hole again. At first it was the same as the other trials. The wormhole was one of the oddest and fascinating things Sheldon had ever seen. He could walk around inside it but there was no proper form of gravity so he could pretty much go whatever way he wanted. Sheldon took several more steps until he noticed his heart rate was increasing rapidly and more so than normal nervousness or excitement. He began to panic and looked around to find the exit but saw nothing. His vision turned dark and the last thing he saw was himself falling.

Sheldon's eyes opened suddenly and his eyes adjusted to sudden bright light. He sat up and saw it was just the basement that he was working in. Sheldon gave a confused look. Each other time he just walked until he got back to the entrance again. However this time he blacked out and woke up in the same place. Sheldon noticed that all his scientific equipment that he was using to create the wormhole was gone. Had someone stolen it whilst he was passed out? Sheldon even noted that the surveillance camera he put up to monitor what happened in the experiments had vanished.

Sheldon looked around the room carefully and found nothing. He sighed and decided that he needed to see if he could find his equipment elsewhere. He walked out of the room and went up the stairs to the university. The university looked the same structurally but he began to notice some of the names on the office doors were different to how he remembered. Did him blacking out effect his eidetic memory? He felt happy when he discovered that his office still had his name on the door. He saw his office desk was black now instead of brown and had a picture of Penny on it.

"What?" he said to himself as he picked it up. The picture of Penny seemed to be a professional work picture.

"Oh there you are sweety." Sheldon heard a familiar voice behind him. He turned to see Penny standing at his office door. She was working professional work clothes which seemed peculiar.

"Hello Penny." Sheldon greeted.

"Where have you been?" Penny asked curiously. "You weren't here earlier and I asked around to see if anyone knew." She added. Sheldon did not want to tell her where he was going or what he was doing at two forty-five.

"I can't tell you." Sheldon said.

"What happened to no secrets between us?!" Penny exclaimed "You put it in the relationship agreement when I requested it!"

"My agreement with Amy is none of your business." Sheldon told her. "And you weren't involved in the creation of it!"

"Who is Amy?" Penny asked angrily. "Is that why you were gone?"

"Penny are you drunk?" Sheldon asked facetiously "It wouldn't surprise me if you were."

Penny gave him a glare. "Fine!" Penny almost screeched "I came here to surprise you and take you to dinner but since you have this Amy I won't even drive you home!" Penny turned around quickly and Sheldon heard her loud footsteps as she walked away from his office. Sheldon sat down on his desk chair and thought about this odd interaction. Did something happen to him in the wormhole?

"Sheldon." Raj walked into the room. "I could hear Penny's shouting from my office. Are you okay?"

"Oh hello Raj." Sheldon greeted "Yes I am fine. I don't know what she was going on about. I'll have to talk to Leonard about it when he drives me home."

"Oh Leonard will not drive you home." Raj interrupted "He is still angry at you about Penny."

"Excuse me?" Sheldon asked.

"Well he wanted to pursuit Penny but she fell for you instead." Raj stated.

"You must be drunk too!" Sheldon exclaimed. "Penny would never pursuit me."

"Maybe you're the drunk one." Raj said "Because you have been dating Penny for two years."

"Yep. Confirmed. You are drunk. How many girls did you need to talk to, to get that drunk?"

"I am fine talking to girls Sheldon. Not that I usually need to." Raj laughed but Sheldon didn't get what was funny. Not atypical for him though.

"What do you mean by that?" Sheldon queried

"You seem out of it today." Raj noticed. "If you need someone to drive you home I will." Raj gave him a smile.

"Ok." Sheldon said "You can drive me home. But not now. I have some stuff to do." Sheldon stood up to look around Caltech for his equipment.

"This car has seat warmers." Sheldon squirmed in his seat. "I hate it! Can you turn it off?!" Sheldon had no idea Raj bought a new car.

"You love the seat warmers usually." Raj said.

"I've never been in this car before Raj." Sheldon corrected. Raj gave a confused facial expression. "And also there is an air-freshener in here!"

"Howard put that in here." Raj told him.

"Well Howard has bad taste. Air-fresheners ruin the feel of a car." Sheldon said. Raj sighed deeply but didn't say anything. The car pulled up to the driveway of Sheldon's apartment building. Sheldon and Raj walked into the building and up the stairs to his apartment.

"What are you going to say to Penny?" Raj asked as they walked up the stairs.

"I am going to ask if she is menstruating and if that is why she is going crazy." Sheldon told him.

"Dude! No!" Raj insisted "That could be a relationship ender! You have to be nice and ask her why she is feeling what she is feeling without insinuating anything."

"We've been friends too long for one question to end our friendship." Sheldon stated.

"Well most platonic friends don't schedule in a 'sex night' for every Saturday." Raj giggled.

Sheldon gave a confused look. "Saturday night is laundry night." He informed Raj. Sheldon grabbed his keys from his pocket and opened the apartment. He saw Penny in it drinking a glass of wine and crying.

"Penny why are you crying?" Sheldon asked as he walked in.

"Why do you think smarty pants?" Penny asked in anger.

"I don't know." Sheldon said honestly. Raj was notably scared of an angry Penny and was keeping his mouth shut.

"Well my own 'boyfriend' is cheating on me!" she stated like it was obvious.

"Leonard is cheating on you?" Sheldon questioned.

"No you are!" Penny began to cry "Don't joke about this!"

Something in Sheldon's mind clicked and his eyes opened wide in shock. It wasn't the blacking out that was effecting his mind. He was actually in a parallel universe. This universe had similarities to his own but the subtle changes were obvious. Everyone in his life still existed but their roles had changed as evident from Penny being his girlfriend in this universe. His mind began to panic. It made sense why he couldn't find his equipment because it didn't exist in this universe. How was he going to get home? Could he get home? Where was Amy? He gulped.

"I'm sorry…" Sheldon thought about what he could say amidst this panic "I was just joking to make you happy." He lied.

"Well don't!" Penny shouted.

"I didn't cheat on you." Sheldon assumed that his parallel universe self didn't cheat on her.

"Then who is Amy?" Penny asked.

"A figment of my imagination." Sheldon made something up. "She is what I nickname the physics-thinking part of my brain."

"Is that really true?" Penny asked. Her tears had stopped flowing but she was anticipating eagerly Sheldon response.

"Of course." Sheldon reassured.

Penny let out a sigh of a relief. "Are you sure?"

"Am I ever wrong about anything?" Sheldon joked.

"That fact that you like the Avengers movie." Raj interrupted with a joke.

"What?" Sheldon asked "The Avengers movie was a masterpiece."

"Sheldon open your eyes." Penny said "That movie got 10% on Rotten Tomatoes and bombed at the box office. It single-handedly stopped the Marvel Cinematic Universe and the comic book movie fad."

Sheldon looked stunned. Of all the places for him to go why did it have to be a one where The Avengers wasn't a good movie? And when did Penny get so knowledgeable about superhero movies?

Suddenly the door swung opened quickly and Sheldon turned to see it was Howard but instead of a Beatles Haircut his hair was all over the place.

"Raj we have good news" Howard was ecstatic about something.

"What is it Howie?" Raj asked. Sheldon noted that Raj used the name Bernadette called Howard. Did that mean Bernadette was in this social circle in this universe?

"We are getting a baby! The donor chose us for adoption!" Howard was almost jumping up and down.

"Oh my gosh!" Raj suddenly hugged Howard and kissed him. Sheldon was thrown back for a second.

"Excuse me." Sheldon interrupted. "You two are in a romantic relationship?"

"Sheldon stop joking around." Penny said "I love your comedic side but you don't need to ruin the moment."

"But…" Sheldon said.

"It is fine." Howard interrupted "We know it is joke. He was Raj's best man after all."

Sheldon didn't need to ask why for this one. He insinuated that Howard and Raj were married.

"Obviously." Sheldon lied "And congratulations on the baby."

"Yes congratulations." Penny smiled at Howard and Raj "I can't wait to babysit for you. Maybe it'll prepare Sheldon and I for parenthood."

Sheldon shuddered a little at the thought of having sex with Penny and producing a child.

"We have to get married first." Sheldon assumed the two weren't married yet.

"That doesn't mean we can't produce a child." Penny said "You sounded so much like your mother then."

Sheldon was curious that his mother was similar in this universe. He assumed his genetic makeup being the same meant that his mother was physically the same.

With all the getting used to this new universe he did not give another thought to how he would get back to his old one until Howard and Raj left the apartment and Penny went to take a shower. He was left by himself in the apartment's living area. Sheldon remembered everything that he figured out to create the wormhole but what guarantee was there that he'd make it back to the correct universe? Maybe he'd have to stay here for eternity? He knew he'd have love and comfort with Penny but he knew that he'd begin to miss Amy who was a better match for him than anyone he'd ever met, even this smarter version of Penny.

Sheldon's laptop in this universe was an Apple brand something which he would never buy back in his previous universe. He turned it on and opened Internet Explorer. He typed in his Facebook and luckily it was already logged in. He didn't know if this universe's Sheldon had a different password. He saw his profile picture was a selfie with him and Penny. He looked at his relationship status and saw he and Penny had indeed been dating for two years and he thought it was possibly even longer given Leonard used to wait months to change his relationship status. Where was Leonard in this universe?

Sheldon typed 'Leonard Hoftstader' into Facebook and saw his profile which had a picture of him in trendy clothing which Sheldon thought was odd. The other thing he noticed was that Leonard had blocked him.

The next name he typed into Facebook was 'Amy Farah-Fowler'. He was extremely curious where she fit into this new world. He saw a profile with a picture of Amy. She looked the same with glasses and long brown hair but she was wearing a wedding dress. She was standing next to unknown male in a suit. Sheldon felt instantly jealous.

Sheldon heard Penny's footsteps come out of the shower and walk into the room. He immediately closed his laptop and turned to look her. She was wearing short pyjamas which revealed more skin than Sheldon would have liked.

"What ya doin'?" Penny asked.

"I was…" Sheldon thought for a second "Working on a paper." His face twitched involuntarily.

"So you've started a new one?" Penny questioned excitedly. He noted that Penny couldn't tell he was lying.

"Yes." He nodded.

"What is it about?" Penny queried.

"You wouldn't understand it." Sheldon told her.

"How many time do we have to go through the experimental physicists aren't dumber than theoretical physicists argument?" Penny questioned.

"You're a physicist?" Sheldon was more confused.

"Of course I am sweety." She added.

"Curious." Sheldon thought to himself. Sheldon wondered what kind of events were different in this parallel universe to cause all these changes and wondered if one event changed or several.

Sheldon noted two tasks he needed to complete:

1. Find more about this parallel universe and why it is the way it is

2. Rebuild the wormhole and get back to Amy

His mind than spontaneously added another task

3. Find Amy in this universe.

"So what is this paper on?" Penny asked again.

"Wormholes." Sheldon said "And how to travel to different parallel universes."

"That sounds interesting." Penny said and Sheldon didn't detect any hint of sarcasm. Not that he'd notice if there was.

Well I wrote this quicker than I expected. This is the start a possible second story and I am a little nervous to read the reviews given the changes in the parallel universe. This is NOT a Shenny story it is just they are paired in this parallel universe. Sheldon's main motivation for getting back will be Amy and there will be some Shamy moments later. Also some of the Parallel Universe science might be inaccurate. I'm only an engineering student after all :D Please review, favourite and follow if you think this is a story worth continuing or not. Thanks you all for giving this new story a chance.
