This has led fans to speculate that the fourth Avengers movie will have some sort of time travel or alternate reality involved, which is where the Quantum Realm comes in.
According to a Vox article, Ant-Man and the Wasp has two end credits scenes - one appearing during the mid-credits and another at the very end, as has been typical of Marvel movies. "And we are starting now the next one which will start a few minutes after Avengers 4 wraps as a story", said Pascal in a 2017 interview with Fandom shared through SlashFilm. The mission goes off without a hitch until Scott radios back to the regular-sized world for Hope and her parents to bring him back, and we see that all three have been killed by Thanos' snap, leaving nothing but ash floating on the breeze as an increasingly panicked Scott tries to reach them.
At issue is how, precisely, Ant-Man and The Wasp fits into the sequence of events established in Avengers: Infinity War, and whether it actually fits into the sequence at all.
Marvel's latest film, Ant-Man and the Wasp was released in United States theatres on Friday, one week before we'll get to see it in India. So that's where we leave Scott: Stuck in the quantum realm, holding a big handful of "healing particles", and not sure what to do or even with a method of escape. Marvel doesn't just toss away key lines like that for nothing; studio head Kevin Feige meticulously maps out every facet of this shared cinematic universe, leading us to believe that these time vortexes will play a role later on. The TV is showing only the "Emergency Broadcast System" signal - probably as a result of the mayhem caused by Thanos.More news: Vladmir Putin-Donald Trump Summit Set For July 16 In Helsinki
"The Quantum Realm is the good news and the bad news in this movie".
Granted, it's pretty unlikely that Scott is going to stay trapped in the Quantum Realm for as long as Jan was, but we shouldn't rule out the possibility that he's going to come out the other side displaying similar energy manipulation abilities, at least temporarily.

"The Quantum Realm is a really intriguing environment and character in the MCU". Or maybe he even learns about Thanos and attempts to warn the Avengers of his presence early on in the MCU's running timeline?
Avengers 4 will arrive in May, 2019.
