Why can't evolution be part of an "intelligent" design?

I am not talking about Creationism at all here, so lets stay off of that issue.

And I am not a proponent of Intelligent Design, but I do think it has some merit.

the universe has been expanding since the big bang. but instead of expanding ast a slower rate, its going faster and faster. scientists think that its because of dark matter.

now if dark matter causes the universe to accelerate, how fast can it make it go. can it accelerate it to near the speed of light? and if thats the case, wouldnt the universe then be infinitely massive?

well we all know that the more the mass the more the gravity right?

and we all know that einsteins theory or relativity states that there is this thing called matterenergy and when objects mass's decrease, the energy increases. so then if that happens then that would mean that if an object has more mass, it has less energy. and it has to make up for that (because everything in nature tries to be equal) and so it makes up for that by pulling in the energy from other matter, which also makes the objects mass bigger thus increasing the gravity.

this works out cause everything in nature tries to equal out, like osmosis.

what do you think?

nd btw. legally you cannot steal this idea, so dont even try unless you want to face some jailtime or a lawsuit

Okay so I live in Minnesota and I have no idea if these little bugs are native to my area or what..

They are really small, a bit bigger than a fruit fly, and are covered in white fluff! They're so pretty but I have no idea what the heck they're called. If anyone could help me out, that would be great! I'm super curious!

I am having trouble with the pattern for 1, 1/2, 1/3, 1/4...

What do I have to do with the number to get the next term?

I thought it would be +1 to the denominator, but the problem has to be adding, subtracting, dividing, or multiplying a number to get the next term and I can't figure it out.

Can anyone help me out?

If x(2) + x =20, what are the values for x that will make the equation true? My book states that answer 1 is correct, I think my book is wrong and I have the right answer the GED book gives these possible choices
(1.) -5 and 4 (book claims this is the right answer)
(2.) -5 and -4
(3.) 5 and 4
(4.) 5 and -4
(5.) Not enough information is given

I think the answer would be 25 and -5 in order = 20
Am I correct and is the book wrong? Please help me. This is driving me nuts.
