The Big Bang describes the beginning of the universe - but we're about to say goodbye to a big part of our universe, with the beloved TV show The Big Bang Theory coming to the end of the road this year - and it's safe to say we're all pretty inconsolable about it.
The thought that we will never again hear Penny sing Sheldon to sleep with 'Soft Kitty', or see Leonard sit in his spot, or watch our favourites struggle up the stairs because that elevator will never get fixed is pretty painful.
But if it's heartbreaking for us, we likely can't even imagine what it's like for the cast of the long-running sitcom.
Watch the Big Bang Theory promo for 12x20 episode 'The Decision Reverberation' here:Kaley Cuoco, who plays Penny, recently gave us a taste of her trauma when she took to social media to share a picture of the last ever Big Bang Theory table read.
Uploading an image of herself in tears, hugging her last TBBT script, with her hair covering her face yesterday, it was enough to pull on the heartstrings of even the most casual fan.
The actress let the photo speak for itself, only writing a short caption that read: "Post table read for @bigbangtheory_cbs finale episode".
Her emotional post collected over 650,000 likes on Instagram and even caught the attention of fellow actress Courteney Cox.
If anyone knows what it's like to do a last table read, it's Courteney who, of course, played Monica Geller for 10 years on Friends.
To support Kaley, she took to the comment section to write: "awww I remember that feeling...and you guys have been together even longer ?♥️??". [sic]
The Cougar Town star wasn't the only one who felt the need to share their feelings; hundreds of fans commented on the post, thanking the Big Bang Theory cast for the past 12 years and begging them not to go.
"Thank you for making us laugh. This is heartbreaking ????," wrote @jessanocom.
She was joined by Instagrammer @bayareanat who said: "I’m hoping for a bazinga at the end of the last episode... saying you’ll be back for two more seasons. ??".
The 33-year-old star was far from the only cast member to take to Instagram after the last table read.
Johnny Galecki, who plays Leonard Hofstadter, also got emotional, sharing a picture of him covering his face with a tissue in his hand, and admitting in his caption that it had not been a pain-free morning.
"This morning was not an easy one. The final table reading for @bigbangtheory_cbsSo very sad. So very grateful," he wrote.
Meanwhile, Mayim Bialik - aka, Amy - was busy posting a tribute to castmate Melissa Rauch, admitting that she couldn't have made it through the last nine years without her.
Cuoco recently shared an intense workout video to her followers:"We have cried together and laughed together and raised kids on a set together. I couldn’t have made it without her with any semblance of sanity," she wrote. "Thank you @themelissarauch for being you. You’re so much more than @thebronzemovie to me. You’re solid gold."
On her own Instagram page, Bernadette star Melissa Rauch wrote that she was cherishing those last fleeting moments with the cast, saying:
"Just because I haven’t flooded my face with enough tears during/after today’s final @bigbangtheory_cbs table read...here’s a pic of our pre-show huddle last night. I was always picked last for every team as a kid, so getting to be a part of a huddle ~ let alone this particular huddle has been extra special. I‘ll forever cherish these moments with my TBBT brothers and sisters. ?"
Kunal Nayyar, or Raj, was seemingly less emotional, simply posting an image that read "End of series". But you don't fool anyone, Kunal! We know you were feeling all of the feels inside!
If you need us, we'll be bawling all the way up to the last Big Bang Theory episode, which airs on May 16, 2019.
