Anyone got the answer?

Last night whilst unable to sleep my mind, as it does, wandered to the origin of the universe and related questions.

I have never fully accepted the Big Bang theory as no one has really explained what caused the largest explosion ever to have happen in the universe to occur.

And if, as it is, generally accepted, the universe is expanding at an ever increasing rate and if there was nothing before the Big Bang then what is the universe expanding into?

I am off to lie down now as my brain hurts.

I am stickin' to my digestive/tea-biscuit theory of the universe ... the holes in the biscuits being the stars.

I think that far galaxies are moving away at about 6000 km / sec. The speed of light is about 300,000 km /sec so light still gets here --- I think! The scientists measure the speed by the Doppler (red shift in the spectrum)) effect.

"If everything is moving away from us at alarming speeds, why is it we can still see them?"

We are not seeing them as they are today what we are seeing is the light that has taken millions/billions of years to reach our telescopes. There is a theory that at some point in time man will look skyward and see nothing but the blackness of space.

I remember from somewhere (maybe a Horizon programme) that the named constellations as set out by the Greeks looked far more like what they were named after than they do today when they used a graphics demo to move the expanding universe back to that time.

But it's still all Greek to me...

The only reference I can find to that movement is here.

...scroll down to "Are the constellations permanent?".

More than one Universe

I have just found the above link and read a small part after the FE corrected my Universe to Galaxies in a earlier posting.

It gave me the idea to Google the possibility of more than one universe.

"There is a theory that at some point in time man will look skyward and see nothing but the blackness of space."

I've never heard of that theory, but it is seriously flawed, and will never come to pass. It would mean that our nearest star - the sun- had ceased to exist, and many millions of years before that happens all life on earth will be obliterated.

Answer, GAS

And if, as it is, generally accepted, the universe is expanding at an ever increasing rate and if there was nothing before the Big Bang then what is the universe expanding into?

Answer, SPACE

Hope that clarifies things for all.
