I will blow up the sun and kill billions of people, does this answer your question?
Because you were not able to separate momentum and energy from time and space, false theories such as the big bang popped up which in reality describe the destruction that is going to happen to your sun by my word.
The Falsehood of the Big Bang
After its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory.
