    It's funny that I tried to watch the video but my mind is like: nah, all these are just made up stories based from scientific assumptions but with less than zero accuracy.. Of course scientists can assume that this is what's going on inside this so call "stars" But really, ask yourselves, How credible are this assumptions are? You observed these stuff using some telescopes And that's it? We humans literally don't know anything baout our oceans And they are within our reach But you tell me, you know "stuff" about these stars? Big no, I don't buy it. I am a very scientific person But my logic is far greater than your scientific assumptions. And the logic is this. --- if you solely based your theories from what you observe from telescopes There's really no point of making assumptions, Because in our universe, There is an endless possibility of everything, in every corner of the universe.. You can't just provide mathematical formulas for everything because everything is literally different in every part of the universe, So making assumptions out of these Equations won't give u the right answers. The only way that we can learn about those stars is to actually examine them physically, Which is impossible, of course. So, Instead of wasting our time learning about those far away objects We should just focus on learning the things the we have here on earth.

    So would strange matter be a potential candidate for exotic matter to create man-made wormholes? The reason I'm drawing this conclusion is if this quark force is strong enough to sometimes prevent stars from collapsing into black holes and instead become neutron stars, couldn't they be used for the same purpose with wormholes to hold them open and prevent them from collapsing?

    Could they gather a small amount of strange droplets and try to use human waste(trash) as a constant fuel that surrounds the strange matter and convert that in to the barrier and enclosure to keep the strange matter from turning everything on the outside in to strange matter. That way trash is converted in to strange matter and never letting it escape. But my question after harvesting is how do you use the energy for us? Maybe they can build something that convert the Neutron state back to protons en electrons letting it make a basic form for energy that can create electricity or another source of power. Just a thought.

    In another video you guys mentioned something about protons having a chance of being temporary and being able to expire That makes me think that strange matter could’ve been what held everything together before the Big Bang and then there could’ve been a part of strange matter that was expirable and that’s what caused the Big Bang Not a scientist or someone who has actual credibility on this subject so this is probably extremely wrong
