Today, our teacher sat us in front of a computer and had us do 15 of these problems. I didn't even finish one, I was so confused and did NOT know when to start, so of course you don't have to do every one of these, but if you can take one through with steps or something, I would REALLY, REALLY appreciate it!! Thanks so much!

If the universe is infinite, than it is expanding into nothingness? How do we know that this empty space is infinite? Is it possible/logical for there to be many 'universes' at various stages of development throughout this infinite space?

Human Embryonic Development was written in the holy Quran 1400 years ago.

http://www.jalyat.net/Human%20Embryonic.htm

In the Holy Quran, God speaks about the stages of man’s embryonic development:


We created man from an extract of clay. Then We made him as a drop in a place of settlement, firmly fixed. Then We made the drop into an alaqah (leech, suspended thing, and blood clot), then We made the alaqah into a mudghah (chewed substance) (Quran, 23:12-14)

Literally, the Arabic word alaqah has three meanings: (1) leech, (2) suspended thing, and (3) blood clot.

In comparing a leech to an embryo in the alaqah stage, we find similarity between the two as we can see in figure 1. Also, the embryo at this stage obtains nourishment from the blood of the mother, similar to the leech, which feeds on the blood of others



The second meaning of the word alaqah is “suspended thing.” This is what we can see in figures 2 and 3, the suspension of the embryo, during the alaqah stage, in the womb of the mother.
The third meaning of the word alaqah is “blood clot.” We find that the external appearance of the embryo and its sacs during the alaqah stage is similar to that of a blood clot. This is due to the presence of relatively large amounts of blood present in the embryo during this stage (see figure 4). Also during this stage, the blood in the embryo does not circulate until the end of the third week. Thus, the embryo at this stage is like a clot of blood.

So the three meanings of the word alaqah correspond accurately to the descriptions of the embryo at the alaqah stage.

The next stage mentioned in the verse is the mudghah stage. The Arabic word mudghah means “chewed substance.” If one were to take a piece of gum and chew it in his or her mouth and then compare it with an embryo at the mudghah stage, we would conclude that the embryo at the mudghah stage acquires the appearance of a chewed substance. This is because of the somites at the back of the embryo that “somewhat resemble teethmarks in a chewed substance

How could Muhammad have possibly known all this 1400 years ago, when scientists have only recently discovered this using advanced equipment and powerful microscopes which did not exist at that time? Hamm and Leeuwenhoek were the first scientists to observe human sperm cells (spermatozoa) using an improved microscope in 1677 (more than 1000 years after Muhammad ). They mistakenly thought that the sperm cell contained a miniature preformed human being that grew when it was deposited in the female genital tract.7

Professor Emeritus Keith L. Moore8 is one of the world’s most prominent scientists in the fields of anatomy and embryology and is the author of the book entitled The Developing Human, which has been translated into eight languages. This book is a scientific reference work and was chosen by a special committee in the United States as the best book authored by one person. Dr. Keith Moore is Professor Emeritus of Anatomy and Cell Biology at the University of Toronto, Toronto, Canada. There, he was Associate Dean of Basic Sciences at the Faculty of Medicine and for years was the Chairman of the Department of Anatomy. In 1984, he received the most distinguished award presented in the field of anatomy in Canada, the J.C.B. Grant Award from the Canadian Association of Anatomists. He has directed many international associations, such as the Canadian and American Association of Anatomists and the Council of the Union of Biological Sciences.

In 1981, during the Seventh Medical Conference in Dammam, Saudi Arabia, Professor Moore said: “It has been a great pleasure for me to help clarify statements in the Quran about human development. It is clear to me that these statements must have come to Muhammad from God, because almost all of this knowledge was not discovered until many centuries later. This proves to me that Muhammad must have been a messenger of God"



Consequently, Professor Moore was asked the following question: “Does this mean that you believe that the Quran is the word of God?” He replied: “I find no difficulty in accepting this.”

During one conference, Professor Moore stated: “....Because the staging of human embryos is complex, owing to the continuous process of change during development, it is proposed that a new system of classification could be developed using the terms mentioned in the Quran and Sunnah (what Muhammad said, did, or approved of). The proposed system is simple, comprehensive, and conforms with present embryological knowledge. The intensive studies of the Quran and hadeeth (reliably transmitted reports by the Prophet Muhammad’s companions of what he said, did, or approved of) in the last four years have revealed a system for classifying human embryos that is amazing since it was recorded in the seventh century A.D. Although Aristotle, the founder of the science of embryology, realized that chick embryos developed in stages from his studies of hen’s eggs in the fourth century B.C., he did not give any details about these stages. As far as it is known from the history of embryology, little was known about the staging and classification of human embryos until the twentieth century. For this reason, the descriptions of the human embryo in the Quran cannot be based on scientific knowledge in the seventh century. The only reasonable conclusion is: these descriptions were revealed to Muhammad from God. He could not have known such details because he was an illiterate man with absolutely no scientific training.” (View the RealPlayer video of this comment

Im here to put forward my arguement that the idea that humans should colonize other planets is not in the distant future for the human race.

First, the human species (and every other species on this planet) evolved specifically to live and thrive on planet Earth. This means that climate conditions, seasonal changes, saltwater and freshwater specific to Earth all had a heavy influence on Earth species. Life on earth is like a key that fits in only one lock: Earth.

Secondly, terraforming (making other planets like planet earth) is a vast, complex, and near impossible problem. Atmospheric oxygen/ nitrogen/ CO2 levels, PH levels in the soil, the influx of sunlight, must all be within a narrow range to accomodate life on earth. This is not to mention to the millions of bacteria, plant and animal species required to keep even an agrocultural ecosystem running.

Finally, if all of this could be done, its still useless. Who would want colonize mars, an antartic, waterless desert?
