re: Do you accept the notion of the Big Bang as the origin of our universe?

Big Bang theory is easy to accept but seems less discussion on how it will all end.

We have known about the accelerating expansion of the Universe since 1998. That's only 20 years. The discovery is so profound that we've had to completely rethink the dynamics of the Universe.

The popular conclusion from the discovery is that the Universe will expand indefinitely and entropy will increase to 100%. That just seems too easy to me.??

We know that something happened to gravity 5-6 billion years ago and that the expansion started speeding up at an increasing rate. The popular take is that the repulsive Dark Force had been around since the Big Bang and that it overcame the attractive force of gravity then.

I think something more exotic took place. Because we know very little about gravity and how it works, my opinion is that gravity itself changed from an attractive to a repulsive state. Obviously it didn't change locally or we wouldn't be here.

However, it may be that distance in space is a factor in how it behaves. Now based on that, I think it could change again to an attractive force in the future, causing the Universe to contract.

So, there may not be an end.

Seems I once read we spend more to operate a local fast food joint than we do to look for objects that will create an ELE.

Yeah, NASA's total budget is $20 billion while our military budget is $600 billion. We spend more on our military than the next 10 countries combined. It's sad that our priorities are so primitive.
