ooby_dooby: Isn't it always the simple questions that are the most difficult to answer?
I wonder if anybody ever tried to calculate how massive that object would have been if it contained every star, planet, galaxy and all the energy in the entire universe.
Hello to all, new to this cyber chat stuff. Here goes ..... F.Y.I. ( majority all just theory remember )From what I have been reading recently about the moments just after the point of the Big Bang. Initially there was no matter only energy. It was too hot( trillions x of degs.) for atoms to form. As the universe cooled the hot plasma of protons and neutrons could form into atoms creating matter ( antimatter also ). From E=MC2, energy creates mass and visa verca, "IF" the speed of light is a constant!
Anyway to get to the point, there was then matter and antimatter present. Problem is that they inihalate each other when they come into contact which they did but there was an imbalance of quantity and some matter remaind. This has been calculated: for all the stars, dust and other stuff, but just within our visible universe, to be 10 to power 50 tonnes.
So there you go Ooby Dooby. A bit of trivia for the next pub quiz or whatever.
Looking forward to any ideas on where all this bleedin' energy came from in the first place, perhaps a colision of matter creating energy, then reverting back to matter, our universe !
Okay, I'll shut up now. Just a bit keen. I'M NEW YOU KNOW :)

Cheers for now Ralph
Hi Ralph, welcome to C S and thank you for your post. It is a very interesting theory you put forward and has a lot of merit. Quite interesting linking energy to matter and vice versa. I don't know who did that calculation but I think 50^10 tons seems puny to me considering the mass of Earth = 6.58542823 × 10^21 short tons. Anyway, I came upon something I thought was very interesting. The distance from the earth to the sun is approx 93 million miles. This is known as 1 Astronomical Unit or AU. The diameter of Betelgeuse (the star not the movie) is 2.57 AU. so, if some all powerful god were to play a game by switching our sun for Betelgeuse, this planet would vaporize in a matter of seconds. What need was there for a flood? Having created the universe god could have taken Noah and his family and 2 of every living thing up into heaven where they would be safe, cast the earth with all the bad people god created into the sun and start over again. Maybe he'd get it right the secong time. But I digress.

.......Do you know any good web sites for this....I find this quite fascinating.....last week my Son and I were talking about 'The Big Bang Theory'......and my question was,and still is....where did this so called Matter come in the first place to cause the big bang........also to ponder about....if there is 'Matter'...could there be 'Anti-Matter'.... now if Matter partial and Anti Matter partial collide with each other,wouldn't there be a massive reaction....like an explosion...???

Hi Ooby, thanks for the welcome, and the initial post. With regards to those figures 10^50= mass of universe. Plagerised from a book I'm reading ( The Goldilocks Enigma- by Paul Williams ). I am no mathematician. This figure was derived from estimating the ( negative ) gravitational energy in the universe = minus 10^50 tonnes. So the mass present is the opposite of that. Hope I have explained this okay and that it is helpfull.
P.S. How do we know it would only be the second time. What if the universe keeps starting over and over again.

Hi J.D.
See my comment above to Ooby on the book I am reading. I can recommend that as a good starting place. It explains in good layman's terms the various theories kicking about for the creation of the universe, matter + anti, physics, time,( search for Grand Unified Theory and also CERN perhaps
