Universe a virtual simulation ?

It is very easy to jump on the bandwagon of pseudo intellectualism but unfortunately it is useless to do so. The universe may be virtual, try going without water for a few weeks or slit your throat. Whats hunger and whats pain, just a few neurons buzzing around in an organ called the brain right?

We perceive a lot through our senses but our understanding of nature goes far beyond the senses. Besides, what do you mean by virtual? All that lingo is suited for sci-fi films not for actual science. Knowledge comes from perseverance and the pursuit of answers, not by sitting down and proclaiming that every thing is virtual. Even to perceive something as virtual some sense organ is needed. As long as a sense organ exists, it will have a physical existence and hence physical reality always will super-cede any spiritual notion.

Please try reading a book on quantum chromodynamics, Bose-Einstein statistics and Fermi-Dirac theories and then try incorporating spirituality into them. If spirituality is really meant to be the absolute truth then it should encompass all these theories right?

Once you can explain the results of the aforementioned experiments/theories then maybe we can regard such spiritual gibberish as an alternative explanation. Till that point, it is just escapism… an attempt to dilute the harshness of the real world with sugar coated fantasies.

Religious people : a view from non-religious side

Actually, I don’t think religious people are stupid. Some of them are ignorant, but that’s not the same thing as being stupid.

Look up “optical illusion” on wikipedia . Look at all the different optical illusions collected there, all of the ways our own visual system tricks itself into seeing things not as they really are. Just looking at them, they remain illusions, one has to analyze them properly to break the spell. Measure things, cover parts of the image, different ways of breaking the spell of different illusions.
We see optical illusions because of the way our brain is organized, and it is not just our visual system which is organized that way. There are a million ways apart from the visual that our minds “insist” on seeing things not as they really are, and a million different ways to analyze things to break the spell of those mental illusions.

The fact that any of us see through any of the veils of mental illusion is a wonderful thing, but it is a trap to think that you have seen through all of the veils.

Religious people are seeing the illusion of god and have not yet found the mental trick that will break through the spell of illusion so they can see the illusion for what it is. They may even have seen through some other illusions, but they are stuck on the god illusion.

We are not stupid when we see an optical illusion that disguises what is really there, similarly the religious are not stupid just because they are stuck on one illusion that you may have seen through.

Boundary of Universe

Although there could be numerous possibilities. Even our current limited knowledge provides many possibilities like -

1. End of Universe as in distance.
2. There are multiple dimensions.

If we think from distance perspective. We know,a galaxy is a collection…gravity bounds everything in it and gives it a picture that we call galaxy. Similarly we have galaxies group where numerous galaxies are just one cluster. If see there is sufficient distance between galaxies to galaxies, and, cluster to cluster.

Similarly we can say there could be numerous universes. However, they are so away from each other that. Probably a trillion universe like ours might fill in between the empty space of two close galaxies. They might as well have different physics because such such huge space difference allows them to hold different laws. Probably the distance is so great that not even slightest gravitation of our universe reaches them.

Now lets next possibility - multiple dimensions. This is amazing!!

Just imagine, how many one dimension object (assume a dot) you can fill in two dimension object, say a line. Answer is unlimited. Similarly, extend this logic for filling two dimensions into three dimension. Answer again is unlimited.

We human and everything around us is three dimension, happily living in 3 dimension universe. However, there could be numerous such universes lying in 4 dimensions.

Boundary of Earth

Yes, scientifically boundary of earth includes -
1. The solid sphere we live at, ofcourse including oceans.
2. Atmosphere, that scientists have divided into 3-4 layers and extends some hundred kilometres from earth (I guess the last is Ionsphere)

In short, when earth revolves around sun, whatever it carries along with itself is earth and the border will be its boundary.

We don’t even need to think any beyond since it is sufficient for our understanding.

Skeptical Drive #1

This post will be answer to some of the questions we hear from those who just attribute gaps to some higher entity. So this post is all about answering those questions.

1- do you see your mind ?

I understand how my mind works and why I have the thoughts I do; how genetics effected my thought patterns and sociological events have triggered stimuli in me. You are much the same; constant Pavlovian conditioning to believe in the make-believe (god, religion - all completely baseless and imaginitive concepts with no basis in reality or truth.) has shaped your mind.

2- who is cotroling cromosoms ?

Who? No one. Evolutionary principles cause chromosomatic shifts. Mutations that are more adapt at dealing with their environment thrive, while the less adept die off.

3- who made Big Bang !

No one made it. It’s what would happen when incredibly large amounts of mass coalesce into a super-tiny area. Gravty causes the attraction, but eventually as energy increases and the laws of energy conservation mean that it has to give off mass and/or energy. The whole thing explodes at approximately the speed of light. Bang. Very big.

4- who created Peoples !

Technically? Chimpanzees. We evolved just like every other observable species.

There is evidence that maybe outside forces played a part in human evolution, but certainly not god… God wouldn’t have reversed the evolutionary traits of our skeletal system, which is what has happened with us vs. chimps. But that’s a whole different discussion that is entirely rooted in science, and yet another place where god is non-existant and not a factor.

5- where is the coming energy for life ( for example …for electron motion ? )

Heat. Motion. Pressure. What about these makes no sense? Go read like an introduction to physics. It will answer a lot of questions.

*phew* that’s all for this time. There will be more questions hitting in comments soon. I’ll answer them as soon as i get them. So watch out for skeptical drive #2.
