1) Message boards : Science (non-SETI) : Big Bang or Big Blooper?? (Message 1507428)
Posted 2 days ago by Profile SciManStev
I hesitated to open that can of worms but the statement that most Americans don't believe in the big bang theory or any scientific explanation for how things began begs the question, why? I saw on the NG channel last week a segment of a program about Noah's ark where a fellow conducts rafting tours of the Grand Canyon claiming it is evidence that the world is only 4600 yrs. old plus or minus. This kind of belief in this day and age truly mystifies me.

I have come to the conclusion that the real question is not whether the U.S. will make it to the end of the century, but rather how did we make it this far?

In my mind, the task is to follow the evidence. The universe is expanding, which states that it was smaller in the past. The rate of expansion is increasing, and we still don't know why. The observable evidence, including the radio background radiation being everywhere, indicates a very dense beginning. Density of that magnitude means extreme heat. With that much heat and density knowledge of physics grows weak. That is why we can understand the physics a trillionth, of a trillionth, of a trillionths of a second after the initial event, and through the present and future, but not at or before the event.

In a court of law, lawyers do their best to present evidence, and a determination by judge or jury is based on the evidence presented. There are many cases where years after a conviction, new evidence comes to light that can sometimes clear the person of having committed the crime. The best tool we have is to follow the evidence, and test it as we can. By performing experiments in physics, coupled with observation, the result that most fits is that there was a huge explosion that started everything.

I have also heard it described as a version of string theory. The basis for string theory is that matter changes based on the frequency of tiny strings. There are 6 different string theories, and they are not compatible with each other. By involving 11 dimensions, the math works out, and the strings are replaced by membranes. If two membranes were oscillating next to each other, and touched, that would change the frequency of their vibrations at the point of contact. It is like two sheets blowing in the wind. The point at which the sheets touched like a ripple, would become the existing universe. This is only a possible theory, like the big bang. I am not aware of any other theories than meet the observable or mathematical evidence.

A brief time line of events:
The initial event was 13.75 billion years ago.

The earth was formed 4.5 billion years ago, and is still forming today.

Man was first on the earth roughly 1 million years ago.

All recorded history spans just a few thousand years.

In 5 to 7 billion years, our sun will use up its hydrogen fuel and expand into a red giant, engulfing and incinerating the earth.

At some point all the stars will run out of their fuel, and die one of several possible deaths due completely to their size.

Red dwarf stars, which are smaller than typical stars, burn cooler, and thus will last for trillions of years instead of billions.

Brown dwarf stars will last longer, and black holes will be the last remnants of the universe, and eventually they will evaporate.

The total time is about 10^100 years.

The entire existence of this planet, and all life on it is only about a millisecond out of a trillion year time span. This is where we get by following the evidence. If our perception of the evidence changes, then we may more accurately understand where we came from, where we are, and where we are going.

This is a very good explanation of where the Universe came from, and what its state will be. Of course, our knowledge of actual events is changing all the time, but this is some good science. The Interactive section is also quite good.

http://www.pbs.org/wgbh/nova/space/history-universe.html

One point that stands out very clearly, is that the earth is really an insignificant lump of rock that will disappear hundreds of trillions of years before the universe goes dark and evaporates.

Angela, you have the west coast covered. I do my best to feed the east coast raccoons, but I only see them in infrared, so it is hard to name them.

My job is to keep putting out food, and keep them coming here. Actually, I feed every animal that comes in my yard. Foxes, skunks, porcupines, deer, turkeys, pheasants, bear, and even stray cats.

I feed snakes also, but only pre-frozen food......

5) Message boards : Number crunching : Correct delete of HDD before new OS install? (Message 1504402)
Posted 9 days ago by Profile SciManStev
I would use something like Partition Master, and Delete the partition. You can do a secure drive wipe at the same time. When the disk has no partition, install Win 8, and it will build the partition to it's requirements, before formatting it exactly as it wants. When reinstalling an OS, or installing a fresh OS, I always start with a non-partitioned hard drive.

Well, saving gas for future to warm that ice age instead of just burning it now will be good thing too. Still looks like win-win proposal ;)

Agreed. 100%

That would be real good and not only for Ukraine but for Earth as whole - burning produces lot of CO2 and we have beed told constantly that warming effect grows...

This is true, but also, in 1500 years, we will be in another ice age. The "warming" is actually delaying that a few hundred years, but in 1500 years, the earth's orbit and tilt, will bring us to another ice age.

I guess it what we do between now and then that could alter things, if only to a portion of the natural occurrences.

What wasn't planned was how long it would take, and still not have control of Iraq's oil. I consider that a huge blunder on the US's part, and it never should have happened.
The US doesn't need foreign oil as much as it did only a decade ago because of franking. Canada is begging US to take more and the US at present burns off 30% of the Natural Gas it pumps along with oil because there is no place to put it.

The Western World is treating this "crises" with a big yarn, nether gold or oil has gone up.

You are right about the fracking reducing the US dependance on foreign oil sources.
Things have changed a lot in the last 10-15 years.

This is a reasonably well balanced opinion. Fareed Zakaria is well known for understanding the situations around the world.

Steve

I'm afraid not.
He allows factological errors that makes his opinion and fairness very questionable:

We invaded Iraq, we invaded Afghanistan, and Putin still invaded Georgia and he still annexed Abkhazia and South Ossetia.

Thank you!
All I want is an unbiased account of what is happening. I know the US has done some really stupid things in the past. The second war with Iraq, was all about oil, and was planned long before 911. What wasn't planned was how long it would take, and still not have control of Iraq's oil. I consider that a huge blunder on the US's part, and it never should have happened.

Posted 21 days ago by Profile SciManStev
A light year is still linked to earth measure, ie. the year. On a planet with a longer year their definition of a light year would be longer.

As long as the end result is equal. It is a specific distance, whether defined in miles, kilometers, light years, or any other unit of measure.

Was Nora the one that hated everybody?

No Nora was the best cat I ever had. He was the one that would drink my tea and turn on my radio in the middle of the night if I forgot to feed him. He was a very smart cat.

tURN THE RADIO ON? REALLY? i GOT TO TEACH MY KIDS THAT ONE.

mEOW

Heck, my kitty Graham just rebooted or shut down my computer. I spent a long time trying to determine that.

I always tended to think of intellect before what sex a person is. Educated and informed people can be either male or female, as can those without those qualities.

The person representing Kenzie had the intellect and knowledge that separated him/her from many.

Even though there was deceit, there was also understanding.

Posted 52 days ago by Profile SciManStev
You get plenty of pic's over here of croc's eating very large sharks (and other large animals plus humans), but it's very rare to get to see something making a meal of a croc. :-D

The Australian Scrub Python is known to grow up to 8.5m (approx. 28') so a 3-4m (10-13') croc isn't really a problem for them (they really do need to eat more of them though ATM).

Cheers.

Your information is 100% correct.
