2. Distinguishing between acceleration and gravity

Yes, this is true because the universe is uniform. This is how the General Theory explains inertia as another manifestation of gravity. Or put another way, there are gravitational waves all over the universe, going every direction, much like the background radiation. These omnipresent gravitational forces keep everything that is still from moving without an external force applied. These gravitational forces also keep everything that is moving, moving a constant speed unless an external force is applied.
3. Distinguishing between acceleration and gravity

As swansont pointed out, E=mc2 refers to the energy within any matter with mass. It is from the Special Theory of Relativity not the General Theory. Einstein showed us inertia and gravity are two manifestations of the same force. If I am standing still there are billions of stars in front of me. Almost all of them are so far away that each on of them has an infinitesimal affect on my. But since there are billions of them they add up to a strong gravitational force in front of me. But they don't pull me forward because there is just as many stars behind me pulling me backwards. These gravitational forces keep me in my place unless I apply a force to move. Once I start moving I am passing by some matter in the universe but as long as I am going a constant speed there are just as many stars in front of me as behind. For that reason their gravitational force keep me moving the same speed. I just explained inertia as if it was gravity. That's the General Theory of Relativity.
4. When does life begin?

No one is saying masturbation is murder. Out of the people that have replied to this thread, no one is even saying any abortion after conception is murder. What you, iNow, seem to be saying is that defining life is too hard and we shouldn't even have this discussion. Lawmakers look to science to determine laws about abortion. If scientist won't even address the issue of when a fetus is a human life then our laws will be chaotic. I agree that laws about euthanasia and assisted suicide should not be decided by people that don't even have a voice in the matter. If someones life is dragging on in agony the only ones that should be involved in any decision on assisted suicide should be the immediate family. Not Washington lawmakers. I don't know if we should take the same stance on abortion. Abortion into the 9th month as long as the mother and rest of the family agrees?
5. When does life begin?

But we MUST create policies and laws on when a fetus becomes a human. People say abortion is murder. We all agree murder is wrong. So when is abortion murder? Anytime after conception? When the fetus is viable? Is abortion always murder? ... never murder?
6. When does life begin?

From a scientific point of view, sounds like everyone is in agreement, the building of a human is gradual process. There is no sudden event that the embryo becomes a human. For the religious, the gradual building of a human doesn't make any sense. They need a miraculous event that God says "let there be life". Conception makes sense. That's the time they believe that God infuses the fetus with a soul (whatever that is)
7. When does life begin?

Some people believe life begins at conception. It actually begins before that. Every egg cell, sperm cell and blood cell in our bodies are alive. The much more important question in the abortion debate is when does that life become human? Science and federal law say it is a human life when the baby is viable to live outside the mother. It is true that at conception the egg cell has a complete set of genes but it is not yet a human life. If I were to hire an architect to design a million dollar home but then someone were to destroy those plans, I could not sue for a million dollars. It is not yet a home although the plans show just what the final house would look like.
8. Why universe appears to have only 3 spatial + 1 time dimension

Uhm . . Yes, he did say time is the 4th dimension. That's his General Theory of Relativity. Time is the 4th dimension. He is the one that coined the word "spacetime" to encompass all 4 dimensions. You say spacetime is 4D Space is 3 dimensional and time is the 4th dimension. Together they make up the 4 dimensional spacetime continuum. I don't understand your position and I'm not sure you do either.
9. ﻿Are we overpopulated?

Well, what's everyone think? I think I may come across as an alarmist but I really do think the biggest problems facing planet Earth are all caused by human overpopulation. Problems such as pollution, feeding the humans, global warming, animal environment and extinction, etc. I think the human population has more impact on Earth than all other animals put together. On the other hand, some say humans are the most important animal on Earth and to a certain degree I have to agree.
10. Gravitational waves in space time continuum

Don't get all hung up about the gravitational waves. Older theories on gravity can explain the gravitational forces. Even Newton's equations on gravity are still used to put a satellite in orbit. So when you ask about large objects throwing smaller objects out of orbit, yes, even Newton and Kepler knew how this could happen. You talk about these gravitational waves having an effect far from the source of that gravity. Yes this happens. As a matter of fact Einstein showed, in his General Theory of Relativity, that inertia is actually another form of gravity. Let me explain. If I am standing still there are billions of stars in front of me. Almost all of them are so far away that each on of them has an infinitesimal affect on my. But since there are billions of them they add up to a strong gravitational force in front of me. But they don't pull me forward because there is just as many stars behind me pulling me backwards. These gravitational forces keep me in my place unless I apply a force to move. Once I start moving I am passing by some matter in the universe but as long as I am going a constant speed there are just as many stars in front of me as behind. For that reason their gravitational force keep me moving the same speed. I just explained inertia as if it was gravity. That's Einstein. Inertia IS gravity. So what I am saying is I think gravitational waves are confusing your understanding of gravity.
11. OTHER PEOPLE dont exist! You are the ONLY person alive, heres the proof.

Run for your lives?
12. ﻿Are we overpopulated?

Vote now. I think that religious people are more likely to believe the whole world is for humans. That human life is good and the more people, the better. But I think that is a very anthropocentric position. I believe the world is very much overpopulated with people. If you fly over the northeastern US, from Boston to New York and beyond you see dense cities that then give way to suburbs but no wilderness, then more dense cities. Flying over the Midwest you see a grid-like pattern of farmlands. All the fertile land is used to feed humans. In the west there is more rocky terrain that can't be farmed. While we can't farm mountainous, rocky terrain we can farm dry areas by piping in water from far away. Farms here look like many circular fields because of the round coverage of the irrigation systems. Let's compare us to the white tail deer we have here in the US. What if white tail deer were to populate every continent. What if most of them lived in herds of hundreds of thousands, or even over a million deer. They would never be able to find food within such large herds so the deer would take over all the fertile land to grow food. Herds of more than a million would even populate the most desolate deserts (think Phoenix AZ). Populating these deserts would entail bringing water down from the mountains or other places with water. Who in their right mind would say that is not overpopulation? Anyone saying those deer are not overpopulated must believe that deer are so special that there could never be too many.
13. Do We Need So Many Other Animals on Earth?

So your stance is that the whole world with all it's wildlife are only here for our enjoyment. It any animal does not bring us enjoyment or food it has no purpose?
14. Do We Need So Many Other Animals on Earth?

WOW I don't know what to say. Hard to believe there are people like Dekan that think any animal that doesn't benifit mankind should be exterminated? ! ? ! One big city over the world? Animals only in parks if they are harmless like ducks in a pond? That would be hell. I live in Colorado. I love getting out into the mountains and into the "wilderness". There really isn't much wilderness left. I hope to see lots of wild animals when I'm out. Animals such as bear, wolfs and if I'm lucky mountain lions. There is very little danger. No animal hunts down humans for prey. We humans have overpopulated this world. Earth needs more wilderness.
15. Must Evolution [read: abiogenesis] and the Big Bang be taken on faith?

It doesn't take any faith to believe science. Any detail in science can be challenged and this is how science evolves. Evolution is a fact. Scientist only debate the details now. The issue is you must understand the current scientific theories to debate them. A collage graduate questioning the origin of life doesn't have much credibility. The scientists that are shaping the modern understanding of the origins of life have been studying this for years and they get thier information from the other scientists that have spent thier lives studying this. Then you get a layman saying “how did evolution begin? In our best experiments, we can barely produce a fraction of a protein” You can't expect a scientist to mix up some mud in a test tube and have a single cell crawl out. Look at the timeline of evolution. It takes one million years for a new species to develop. Such as a new finch. The first life was nothing nearly as complex as a cell. It was a self replicating molecule. If it broke, similar atoms could combine to make it whole again. The part that broke off could do the same. It took 2 billion years before a cell developed. It took another billion years for multicellular life to form. As life became more complex it could evolve faster but keep in mind nothing can evolve in the short timeframes we humans are used to. This is why people doubt evolution. They want to see it with their own eyes. We have proof. Once multi cell organisms evolved evolution was faster (now we are talking 100's of millions of years). Five and six hundred million years ago were the first plants and the simplest animals. That's how far back you have to go to see the connection between plants and animals. 300 million years ago were the first reptiles. The first and biggest problem that people have that doubt evolution is they fail to understand the timeline.
16. Science Vs The Soul

Is gravity a law of nature or "just" a theory? A law of nature is how reality exists outside of human understanding. A theory is our (human) understanding of reality. When a theory is proven it doesn't become a law of nature. Gravity is a law of nature. Then Newton came up with his theories on gravity. Later Einstein came up with his (General Theory of Relativity). Did that mean Newton was wrong? No, Newton's equations are till used to put a satellite in orbit. I like doG's post and I will quote him often. Religion is based on faith. Science is based on facts. That's not to say religions are wrong. The best way to accept both is to say God only works through the laws of nature.
17. Science Vs The Soul

What is the soul? I don't think it exists. Religion invented the soul. It's supposed to be yourself independent from your body. The soul was invented for the sake of the afterlife. There is no way you could prove the existance of the soul but I'd like to hear a good explanation of what the soul is. imatfaal, you say the soul "works through molecular activity rates" That's far from the conventional view that your soul can go on to heaven. Your explanatin sounds more like an explanation of the mind. I think the mind is nothing more than the thought processes of the brain.
