A. Matter can be created.... E=MC**2
With enough energy, one could create matter... and it is relatively easier to create energy from matter.
One of the laws of thermodynamics says that energy could not be created or destroyed, only converted... this law was also modifiedby E=MC**2
B. Quantum mechanics postulates that probability governs the realm of the very small. The origins of the universe are in that realm. The universe was created because it could be.
C. Heat. ---> Energy. ---> Quantum mechanic probability.---> Kuuullax
D. No
a. before there was anything, what could have created this energy?
b. roadkill ( no offense to you) That's almost that same as saying magic created the universe (to which I would ask, what created magic)
c. without matter, what caused the heat and energy?
d. I agree
Someone answered that he Big Bang started the expansion of the Universe.
Part of my question was "what caused the Big Bang?", and then, what caused the event that caused the Big Bang, and on and on.
In other words, the starting point of the Big Bang can never be logically determined, because it would mean looking back on an infinite chain of events.
Just as it is too simple ( asinine) to say that all matter was created "because it could be", it is equally simple to just say the "Big Bang" caused the expansion without asking what caused the Big Bang and, in turn, what caused the event that caused the Big Bang.... and what caused that event....... and so on, forever....
And this Big Bang is not even dealing with the issue of what created all the matter in the Universe. It can't be reasoned (IMO) that all the matter just always existed, yet it cannot be reasoned that it was created from nothing either.
