Big-Bang? Do you believe it? I don't. Being a career engineering-physicist, I always look for proof. For 50 years I have tried to prove the BB to myself. I have reviewed Slipher's red shift observation, reinterpreted it, and corrected Hubble's declaration, (the universe is not expanding and exploding to its death, instead, it is growing with vim and vigor). Red shift defines velocity, not acceleration or deceleration. So, I developed the New Universe Theory which is believable because it complies with known facts and the Laws of Physics.
