Yes i do believe in multiverse. One such thing is black hole, about which Stephen hawking had shared fine information.
some Said there maybe a universe inside it.

One thing is very interesting i have found...scientists claim that gravity is so strong on the event horizon of black hole, that even light can't escape it (remember here light has the speed which no other thing can match). They say stars when die fall into it. Then i remember surah najam's ayah in quran where Allah swears and says "and when star falls into it", next Allah shares the journey of Prophet(PBUH) on sky and how he saw black hole.
These things are so remarkable and firm the belief of a momin on Allah❤

Hahahahaha for your last remark, humbled🙇:)
