Nah. Gravity always pull things together. Dark matter is a crutch to explain why galaxes can keep together. Dark energy is the crutch to explain why the red shift is accelerating (that means that the universe is expanding faster and faster). That's why it's so vague and will probably be another aether.Quote:

You guys haven't been paying attention.
Before the Big Bang there was the Q continuum. Any fule knos that.
Oh and 42.
A faulty assumption that is also the basis of the Hawking-Penrose theorem. OP is about finding evidence for the inflation period which is THE explanation of the uniform red shift and the explanation of the flatness/horizon problems with the general BB theory. Inflation needs gravitational force which is not attractive in nature (repulsive). Until one has developed such a theorem (Quantum theory of gravity), it's all hypothetical.Quote:

No. There are observations that things move out and retract. We can't explain why this is happening, and so we fill in the blanks of our knowledge with "dark matter did it".Quote:

I think you've mixed them together. It's quite easy to do. The one coming up with dark energy were really not thinking about the risk of name mixup, only theme names.
Basically, it goes something like this. The formula used work fine on small scale and large scale, but are completly wrong on gigantic scale. So either the formula is incomplete or you fudge the numbers and acknowledge that you did that and tell everyone that you describe something real that haven't been discovered yet. Sometimes, the rest agrees with you on that. Sometimes, it's even correct.
Campare to "what caused the Big Bang?" There's certainly no seriously taken formulas to calculate that.
it might turn out that the whole idea of a big bang is making us biased and thus leading us into a dead end. We lack the tools and knowledge to look deep down enough, far back enough and so on.

Its is all the same one.Quote:

Long story short, that is a silly statement which lacks understanding of the great diversity of religion. Only one which 'share' are the Christians, Muslims and Jews. Even then, sects of those have difference ideas and views on the makeup of 'god'. Is some one who is doubting the divinity of christ actually believing in the same god as some one who believes Jesus is the embodiment of god?
What defines a 'god' anyway? What if the big bang was an Alien Ships reactor-drive malfunction in a different universe, thus creating a pocket-universe of us. Does that make them 'god' ? or is the creator of the universe who created things which happened outside of their control in turn created us from said aliens given free-will.
The mind boggles on the amount of mental hoops which are completely ignored.
I am sure if there was an afterlife with an omnipotent being, they would be fully understanding of any lack of faith and enlighten us. So no need to worry about your eternal soul.
Religion and mythology blend in the times of antiquity. They used to serve a different purpose in those ancient societies. The plethora of ancients gods, spirits, heroes of old, great foes and so on are archetypes of human behaviour. They tell stories which concern the fundamental characteristics of humans. Religion often intertwined with the cultural rituals which marked the coming of age of young adults - a paramount point in one's life. Ancient religions are multifaceted, because there existed no such phenomenon as globalization back then. Each region, each tribe, each distinct peoples adde their own colour and taste to fundamentally the most basic and eternal of human stories. Love, war, betrayal, coming of age, death, motherhood, cunning etc.Quote:

But such theological debates are not the purpose of this thread, though I do appreciate them greatly. Also, Zeus was a notorious adulterer - he fathered half the pantheon and Greek heroes, nymphs and very pretty girls. If that's not an excuse for men of power to shag anything that moves, I don't know what is. "Look, Zeus did it. I can't presume I'm better than the Lord of Olympus." :laugh4:
