I think that my Grandmother has the Largest Southern Magnolia tree ever. It's HUGE! So, how do I register it as the largest Southern Magnolia? Guiness World Book of Records seems to only do human submissions now but there's got to be another way to register this massive tree, right? Any ideas out there?

My Geology 102 textbook makes some basic statements about the formation of the universe and the solar system. One of these statements is that the universe is constantly expanding. My question is, expanding into what? Expanding relative to what? Another statement is that the universe started from a "big bang." I have heard of this theory before but have never understood it. What caused the "big bang?"

I need to presence sense a row of several magnets (6-20, depending on the machine size) that are repeatedly placed onto and collected from a steel surface. I need to determine a "signature" of the magnetic field of the group, then check each time they are placed/collected to ensure that none are missing. Thought is to run a strip of the desired material close alongside the row, and check the resistance (signature) with an ohmmeter.

I'd also be interested in any other ideas to accomplish this.

Thanks in advance!

What exactly exploded
And how did it get there, or was there nothing there before it

If nothing was there, did nothing explode
and if nothing exploded why was there such a big bang

Have you ever told a lie, stolen anything, or used God's name in vain? Jesus said, "Whoever looks at a woman to lust for her has already committed adultery with her in his heart." Have YOU looked with lust? Will you be guilty on Judgment Day? If you've done these things, God sees you as a lying, thieving, blasphemous, adulterer-at-heart. The Bible warns if you are guilty you will end up in Hell, where you will suffer forever, and I don't mean Katrina bad or earthquake bad because those wounds eventually heal, but this will never end. That's not God's will. He sent his only Son to suffer and die on the cross for YOU. Jesus took your punishment upon Himself: "God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life." Then Jesus rose from the dead and defeated death. Please, repent (turn from sin) today and trust in Jesus, and God will grant you everlasting life.Then read your Bible, obey it and lead others to Him.
