The beginning is impossible to comprehend and without a doubt, there's a beginning. Nothing was turned into matter and energy. I'm dizzy, I need a popsicle.

Or is it possible that the wavelength can be infinitely small or big? Considering that fractions can be an infinite number (.0000001 you can have an infinite amount of zeros making an infinite amount of fractions). If so, do any stars in our solar system emit any other types of waves then those in the known Electromagnetic spectrum?

I claim a complete lack of expertise in this area, so don't hold it against me if I come up with some stupid ideas. I just wonder if there is a way to improve how we look for miners after a collapse.

What if miners began to wear powerful radio transmitters during these operations so that their precise location could be determined in three dimensions after a collapse? Perhaps their three-dimensional position could be cyclically broadcast via radio transmission. At the very least, the strength and source direction of a radio signal would hopefully offer information regarding the location of the miners.

Are these mines just too deep underground for such a thing to work? Then, might fiber-optic cables survive a mine collapse? Perhaps a device kept near the miners could keep track of its own location and transmit this information via cable...

If anyone has thoughts or ideas, speak out. There has to be a solution!

Someone else posted this question and didn't get the right answer. Now I have the same thing in my house...and I don't know what it is or how to get rid of it.

I live in Los Angeles County. It's the end of August and hot as heck, if any of this info helps someone out there figure out what this is.

They're not box elder bugs...they look different.

These things are skinny, about the size of a tic tac. The black, ribbed abdomens are kind bloated compared to the rest of the body and the head is red. What's really creepy are the loose wings all over my bed...ewww...what IS this?

In one day, a store sold 8/5 as many DVDS as CDS. The Total number of DVDS and CDS sold that day was 273. How many DVDS were sold.

Here goes my equation, Is it right?

x+8/5x=273

Im having a hard time turning 8/5 into a whole number how do do this?

Find the domain of the function f (x) ={square root of} (2x+5 / 3x-2)

Read as thus: f of x equals the square root of [2x+5 divided by 3x minus 2].

Please give as much detail as possible, not just an answer!

Thanx a bunch!

are there any other theories aside from the big bang theory, that has a following of people who believe it and there is evidence to support it. or is the big bang the current one the has all of the evidence. also i don't mean religious theories but scientific ones. i know about the other universe theories, i was just wondering if there are other theories that are widely accepted like the big bang, again non-religious

does this sound feasable, because i thought most things would be melted in the molten lava but i wanted to know whether this would cause any adverse reactions like triggering an erruption and or create more green house gas pollution and or any other type of pollution.
