Uncomfortable…
Although I am no expert in physics I just could but grapple with the fact that space was made from nothing and is continuing to expand. Ever since middle school physics class, I was taught about Louis de Broglie and his law of conservation of mass. As the law states, although the shape of the substance may change, shouldn’t the mass be constant? ( Again.. I am not a expert in physics and I could be totally incorrect in referencing Broglie and if I am please forgive me )
I simply cannot grasp how space was created from nothing and can continue to expand as we speak. I hope further research both in and out of class will clarify this situation for me.
