Energy cannot be created nor destroyed. How is that possible when the universe is expanding?
If mass cannot be created nor destroyed, why and how is the Universe expanding?
Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? What does "infinite mass" mean? Scientists say that the universe is expanding, and all the galaxies are moving away from one another. How can they be sure that this is due to expansion and not shrinking of all the matter everywhere in the same ratio? Where did the mass of the universe come from? If space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume? If the universe is infinite, and an object in it changes size, its size relative to the universe stays the same. Why isn't everything the same size? Can we calculate the mass of the universe? Why does God has gone to this length to create the whole universe and a planet only for humans when the end is so inevitable? Can we create some mass from energy? If universe expands and more space-time, dark/vacuum/gravitational energy are created with it, can infinite of these be created (potentially)? We know mass can be converted into energy and vice versa. Are there any instances where energy is converted into mass? Less Volume individual Mass creates more actual life than invidual larger mass? How was matter created when the Big Bang occurred? What fundamentally gives matter mass? As ALL matter is created soon after the Big Bang, and in a relatively small area, why doesn't it collapse into a black hole under its own gravitation? Why didn't the universe just develop into a super massive black hole if in the beginning it was very dense with matter and energy? If mass is energy and vice versa, can you compact energy into matter? What effects could that have on surrounding environment? Could God have created the Big Bang? What would be the outcome of extra mass on earth? How vast is the universe? If the universe is expanding then where does the extra space come from? Is there space outside this universe? Does 'empty' space have mass which is displaced by matter? Why does an object with a large mass have more potential energy than a smaller mass object? As space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume? Why does the mass also increase if the velocity of an object increases? Can we turn mass to energy and vice versa or is it theoretical only?
