Sir, also, regarding this,
"sato bandhumasati niravindan hṛidi pratīṣyākavayo manīṣā ll"
Sages who searched with their heart's thought discovered the existent's kinship in the non-existent.
Rig Veda: Rig-Veda, Book 10: HYMN CXXIX. Creation.
You don't have to wait until science find this, even you can find it. By casting of all desires, and when the mind wondering to find the truth, it reaches this heart, and there is existent's kinship in non-existent, which is otherwise called in scriptures as Ishwara/Not-Creator-God/Sat-Chit-Ananda.
The existent's kinship in non-existence is this non-creator God, which is said in scriptures as,
Atman's kinship with "Appearance of Atman",
Purusha with Prakriti,
Sleeping Narayan in Anantasesha,
Shiva Linga,
Omniscient Lord who dwell in Bliss and never acts.
If Ramana, Jesus (including Viswa ) can feel this bliss in heart, why can't you, why to wait for science? Science cannot find this, as it can only be found within (not outside). Light cannot surpass the space in Universe (light,air,water,land has it's limitations to space) and so no one can witness with eyes beyond universe. Not like Madness of Multiverse where shown that body can survive, body has it's start and end with the universe it is made up of. No atoms can escape the space. Space is the lord of the Universe, and so no non-existence can be found when space-lord is present.
But, it can be found my mind when all it's desires switch off, when all it's attachment and aversion fades away.
So, Mind to inquire? Sure, within your death, science won't find it out. So, as you only live once, why not give it a try?
"Shanti" - what do you feel? Is it "Shanti" for physical energy, or "Shanti" for mind?
