This.  
There is every indication the only other alicorn we KNOW ascended, Cadence, is completely mortal. So far, only Celestia and Luna are immortal.

8. Twilight will commit suicide before the others die.  
9. Twilight will go mad science horse and suspend her friends in time indefinitely and/or until such time she can prolong their life.

@Background Pony #907D  
We have Flurry, Cadence, the Student 6, and any other Alicorns who will come about.

Wait, then who will rule Equestria after Twilight passes?

@Background Pony #5CA5  
I rest my case.

@CronoM  
Why would I admit to something that hasn’t been proven to be true? Twilight was always being groomed to be their successor as far back as season 1. Twilight looking like Celestia is not an indication of how rapidly she ages.
 
Lyra and Bon Bon never would’ve even become a couple had it not been for the fans constantly pushing the idea of them being a thing. It literally only ever got attention because they were a fan favorite background set and Hasbro has been known for catering to the adult fans in some ways.

@Background Pony #5CA5  
Dude, stop trying.
 
This guy will never admit that all signs point to Twilight being immortal. Clearly he’s been given all the evidence one would need, but he isn’t going to admit it to us if he isn’t going to admit it himself. Especially since he feels it’s stupid. Which it is kinda, the idea that Luna would retire and the sisters would pile everything on Twilight was asinine, but it’s still canon.
 
Remember how a depressingly large part of our fandom tried to deny Lyra and Bob Bon were a couple up until the point where Lyra proposed? Our fandom has no shortage of people in denial.

@Background Pony #5CA5  
Twilight outliving her friends was a dumb head cannon people made up back in season 3. Head cannon is not show cannon.

@TheRocketMan
 
No, the burden of proof is on you. You are the one that has to prove that she isn’t like Celestia and Luna despite all the signs pointing that she is.

@Background Pony #5CA5  
No bags under her eyes and floaty hair literally doesn’t mean anything.

@CronoM  
Unless the show itself says she’s immortal, she’s not immortal.

@TheRocketMan
 
The lack of bags under the eyes, the flowing mane. You’re the one that has to prove that Twilight is not like Celestia and Luna.

@TheRocketMan  
Only look alike? Twilight hasn’t aged a day past her prime, unlike the others.
 
Celestia and Luna are age wise immortal so why wouldn’t Twilight be after she became the same type of alicorn as them?

@CronoM  
*Celestia and Luna I meant
 
Your logic doesn’t make sense either. There’s literally nothing that indicates Twilight will outlive her friends. Making her a Celestia look alike is not evidence.

@TheRocketMan  
Luna has. She was on the moon for 1000 years, she wasn’t encased in stone remember? Both of them a large wavy haired alicorns, and now Twilight is a wavy haired alicorn who, at present, has not aged past her prime.
 
Your logic escapes me.

@Background Pony #72C4  
No, I’m simply going by evidence shown in cannon. No other alicorn except Celestia is shown to be long lived or immortal.

@Background Pony #5CA5
 
Not necessarily, she’s the Princess of Friendship. Just cause she lives a long life doesn’t mean she won’t “Stop” making friends.

Besides even if Twilight does die in a few thousands years instead of living forever, it would still be outliving her friends.

@TheRocketMan  
Celestia has literally not aged a day for 1000 years. That goes well beyond long lived. If they wanted to show otherwise, they would of done so.

@TheRocketMan
 
Where? Off had remarks by show staff or in the show?
 
Never heard that in the show sooo it’s up to fan interpretation. I say Immortal.

@CronoM  
Alicorns are not immortal. Celestia and Luna are just repeatedly stated to be long lived.

@TheRocketMan  
Celestia is over a thousand years old and does not age.
 
Celestia is a large alicorn with a flowing mane.
 
Twilight is now a large alicorn with a flowing mane, and shows no signs of aging past her prime just like Celestia.
 
While it’s never been stated outloud, it’s still certainly a fact that age-wise mortality holds no sway over Celestia, and thus, we have no reason to believe it holds sway over Twilight in her 2.0 form.

Why does everyone keep saying she’ll outlive her friends? Alicorn immortality was never stated to be cannon.

@SilentObserver01  
You see her grow from a pre-teen to a teenager through some “non-canon” stuff, and from a teen to a full mare in the show. We notably do not see this in Tia or Luna. Plus, Flurry is a Alicorn that is strange even to Tia and Luna.
