So,i'am under the impression that some of the aspects of this theory i'am about to discuss are already well known among fans but i wanted to collect all the evidences that suggest it may be true.So,here the idea:Sans is trying to fix the machine to return to his original timeline and also to bring Gaster back. So,here some arguments

1.Sans is from another timeline

During his conversation in core's restaurant,he says Something veery intriguing: "you must really wanna go home,hey i understand the feeling" My first impression of this line was that Sans was alive before the war and lived on the surface as monsters are said to live for very long.

But,its pretty clearly not the case given his battle's dialogue :

"i gave up to go back a long time ago and geeting the surface doesnt appeal to me either",

yeah the place he wanted to return to and the surface are two diffrent things.So it appears like Sans's home is neither on the surface and is neither the current place he live,so what could it be ???Yeah,another timeline,after all,its stated by Snowdin's shopkeeper that the skele-bothers "just showed up"one day,as if they appeared from nowhere,as if they came from another timeline…..

2.The broken machine and Sans

As the machine is in his lab ,is described as "broken"plus the fact that Sans has it blueprints,plus the fact that Toby said that the machine cannot be fixed no matter what,those facts combined prove that Sans had tried to fix the machine but failled.But why would he??

As stated before,Sans is likely from another timeline and tried  to come back but gave up,so this is likely the reason of why he tried to fix the machine:to go back home .But what does implies that its a time travel machine??it could be another dt extraction machine right?So here the proof:after Asriel's fight,there's a photo near this machine,the narrator recongnize this photo as the photo of Frisk and all of their friends and so before its taken,since its here before its taken and as its near the machine that implies that this is a time-travel machine.

Given all of this,i think its veeery likely that he tried to fix the machine in order to come back home and to reunite with his friends depicted on one of his photos near the machine.

3.Gaster's connection with this machine and the skelebros

Sans is without doubt somehow related to Gaster as his blasters are called "Gaster blasters"and as besides Papyrus,Gaster is the only other character that use a special front.Toby even confirmed that the two brothers had another relative,even though this anoying dog didnt specify who.Its very likely Gaster as Sans has blasters called after him and he's the only other character that use a special front.

Also,this machine seems to originaly belonged to Gaster as it blueprints are written in "weird symbols"that Frisk cant read .Coincidentally,Gaster is the only character in the game who write in "weird symbols",as you know in wing dings,so we have a strong connection here.

Gaster is also said to "fell in his creation".So,since the time travel machine is likely Gaster's creation,what if he "fell"in this machine??If so,plus combining with the fact that Gaster is very likely Sans's brother/father,i think Sanswould really want to fix this machine to bring him back(which is also implied by the poorly drawn picture of three people that says ‘dont forget’that can be found near Sans’s machine)aswell besides returning to this original timeline. .And remember what i said about this machine??yeah that's very likely a time travel machine and curiosly Gaster "shattered across time and space",since his fragments are scattered across time and space ,its very likely that Sans wanted to fix the machine also in order to travel different timelines and collect Gaster's fragments to fix him and then return to his orginal timeline with his family.

However,what the hell happened to Gaster and why Sans and Papyrus left their timeline? Well,i think that they were present with Gaster durng his experiments that went wrong that were made thanks to the mysterious machine and that were related to time manipulation and the erasement of a timeline .After all,Gaster is talking to two persons during the experiment mentionned in the entry 17(which is stated to be ‘the next one’as if it was following other experiments,that concord with what his followers says ,that Gaster vanished because ‘his EXPERIMENTS went wrong’ and not ‘experiment’as if there were many experiments that followed each other) where everything turn into darkness. Also,keep in mind that the japanese version make clear that the ‘place’Chara and Frisk get after erasing the world is ‘dark’,implying that Gaster was actually erasing the world (likely thanks to his time travel machine).Unfortunately for him,only his brothers could escape the world’s erasement by using the machine to save themselves by going in another timeline (specifically in Snowdin,which is why the the Snowdin’s shopkeeper says that they ‘showed up one day’)while Gaster end up erased (as a mysterious figure that appears in a special fun value says ‘redacted’in wing dings)and shattered across time and space .But this whole part is just speculation ,what’s more or less sure is that Sans is from another timeline and very likely wanted to fix the broken machine to come back.

What do you think??Did you find any counter arguments??What are your theories regarding the mysterious machine and Gaster?
