Those who believe in It and please It will be granted universal knowledge and paradise in the cosmos while those who do not accept It will be stuck forever on Earth wondering about the stars and the heavens and how the Universe came to be until they, in their lifetime or next, accept It and be freed.

My point? You may never know the secrets of the Universe until you learn that just because something lacks evidence doesn't mean it's improbable.

This is just a karmic theory to think about. Imagine that all you had to do was believe but instead you reached out and tried to grab it but it disappeared. The very one thing that you worked so hard to get someone else got with no effort at all, they just simply believed.

If this were true how devastating would it be to the Astronomers who don't believe in Intelligent Design?

I bought a multivitamin formula for my daughter aged 9 on my doctor's advice. I have been reading the "supplements facts" on the bottle and have compared it to the RDI for children aged 4-12. Most of the vitamin / mineral concentrations in the formula are four or five times the RDI. For example the formula contains 250 mg vitamin C (4 times RDI), 120 IU vitamin E (4 times RDI), 135 mcg vitamin B12 (22 times RDI). Is this safe for a child??

In the Star Trek series, they often say a destination is something like 200 light years away. They seem to get there in just a few days or so. The top speed they have traveled on any of their starships is about WARP TEN. Since WARP ONE is equal to the speed of light, that means they it would take one year to travel one light year..., meaning a trip of 200 light years would take 200 years at WARP ONE and 20 years at WARP TEN.
So are they just way off on these shows or am I wrong in my caculations?

At my grandparents old house (in that they dont live there now, the house itself was only about 30 years old) we'd be in the loungeroom and the kitchen taps would turn on full blast - both of them - and then when we went in there as soon as we got to the door they would turn off. This freaked my grandma out, coz it usually happened when it was just her in the house, but sometimes when we were all there. It had never happened when someone was in the kitchen tho, but then one day me, mum and grandma were all in the kitchen and all of a sudden both the taps turned on full blast. We freaked out, and grandma said 'what do you want, why do you keep doing that' (coz she says you have to asks ghosts that incase they need help or something) and the taps turned off. It never happened again when we were there, but from then on it would only happen when grandma was alone in the kitchen. Why would the ghost have done that? was it a ghost? has this happened to any1 else? I still hate taps lol
