Science & Mathematics - 13 August 2007

I've been very recently fascinated with our Universe and had an interesting thought. Our galaxies are comprised billions of stars, planets, etc; The Universe (assuming, sort of, that the universe is an unfathomably large closed system) is comprised of billions of galaxies, dark matter, etc. Do you think that there might be billions of different, "collections of Galaxies", maybe that occupy different laws and natural elements.

To expand your answer. Answer the follow questions in order:

If you agree with the question,
1. What evidence out there that you agree with?
2. What is/are the evidence that you find very interesting and/or most convincing? Try to narrow your choice down to 2 or 3.
3. What's your thoughts on why NASA is not confessing? Will they ever admit that they're wrong? What would you do to make them leak the truth (that they faked the whole thing up)?
4. Do you think that this is the greatest hoax of all time? If not, then what is?

If you diagree, then answer these questions:
5. Why? What ARE the evidence that convince you? Specify.
6. Why do you think that there is the growing uncertainy about the moon landings?
7. What is it that makes you trust NASA so much and you are sure (and crystal clear) that man did land on the moon?

The law of conservation of mass/matter, also known as law of mass/matter conservation states that matter cannot be created nor destroyed, although it may change form. How did Matter exist in the first place if not from a Creator?

If the continent sized block of ice keeps melting, and has nothing left to anchor it, it would almost certainly rotate slower than the planet due to friction. Then it would start crashing into land masses causing earthquakes, and perhaps would de-stabilized the Earth's Axis of Rotation noticably. RIGHT ?

I'm planning on studying medicine and have eben studying it on my own for a few years now. I'm currently researching Percutaneous Transluminal Coronary Angioplasty, and I think have pretty much everything I need except one thing - I can't seem to figure out which analgesic and which sedative/s are used for the procedure. If anyone can help me out with this, I'd really appreciate it. Thanks, it'd be really useful. =)

They get all this crap info on TV and the internet and spread it around without sitting down and thinking. For example:

Moon landing hoax: How could the govt fool 400,000 people that worked on Apollo for 11 years that 6 moon landing simulations over 3 years were real?

Govt brings down the World Trade Center: If it wasn’t hijacked United and American airliners that did it, don’t these people wonder why when watching the videos of 9/11, all the hundreds of personnel working for those airlines weren’t screaming “we didn’t lose any airliners that day”.

Mars appearing as big as the Moon: Doesn’t this one get you? If people thought for a just a minute, such a scenario would be huge for Earth’s tides, and it would be all over the daily newspapers.

I noticed it first on my bike tires when I increased the air pressure to almost the maximum and used it on my roller (a treadmill-like device that lets you ride your bike indoors --> http://www.bikesomewhere.com/images/big/elite_parabolic.jpg )

I also noticed it on my car tires after I increased the tire pressure (recommended in hybrid groups to maximize mpg). But I didn't notice it until I drove the car on the freeway. Most of my daily commute is on surface street.

Based on the above, my theory is it happens when the the tire heats up. Does the spike grow until it falls off or does it recede back to the tire? Does it have any effect on the tire?

Here's a picture of how it looks like --> http://farm2.static.flickr.com/1169/1107702767_e08404d9c8.jpg?v=0

I want to know the science behind it hence the category.

Thanks!
