  Aug 3 2011: interesting...

• A reply on Conversation: Is the universe finite or infinte.

  Aug 2 2011: I feel like using this as the conclusion, but I am not 100% certain that because something cannot be destroyed it's infinite. Energy can't be created or destroyed but does not nescessarily mean it's infinite, like if there is 2J of potential energy in something - It can't be created or destroyed but it's still 2 Joules... not infinite Joules. Besides all of the above, Energy is just a concept we use to understand many physical concepts, it doesn't actually exist, just like numbers.

  Aug 2 2011: Good explanation, it would be like the scale expanding, but not actually expanding, so like lets say 1 2 and 3 are each a meter apart, and by expanding the actual defining length of a meter, you are stretching the numbers apart, expanding them, but they are still each a meter apart,. The only thing that changed was the defining length of a meter. This reminds me of the thought that there is no way to tell if everyone perceives time the same. For example I may experience 3 seconds as you would experience 1 second, but to the both of us it would still be defined as 1 second.

  Aug 2 2011: Interesting thought, but seeing as energy cannot be destroyed nor created, it means energy would be infinite, which brings us back to square 1. Is there infinite energy in the universe?

  Aug 2 2011: Very good points here, I believe so as well, but the real thing is, if you conitnued to add 1 to that biggest number and someone continued it for u when u died, it would go on for infinity, so the it gets confusing because you might think that the universe is then infinite cuz of the chocolate bar example I gave, something finite cannot contain something infinite. Hard to think of haha

  Aug 2 2011: Eduard, the same question has been asked about many things in history like "is the earth flat? - Does it matter?" and clearly it does. Well same with this scenario; in the future, it will matter A LOT if the universe is infinite or not, for example let's say a few thousand years from now or even sooner, some company decides they want to travel to the end of the universe. This would not be possible if it was infinite, and another thing is, imagine if we had fully understood wormholes and wanted to warp space-time and travel to another location, if the universe was infinite this would not be possible because every x, y, and z location in the universe would be ∞ (infinite) because it would stretch infinite metres (or whatever unit) in every direction which means we would have to use normal methods of travel which, on the scale of the universe, is very slow.

  A comment on Conversation: Read my words and then tell me if science is a religion or not.

  Jul 31 2011: I changed my mind, science is not a religion. I can explain why by using your example, where you said "Its not often that people can have two different religions at the same time" Well let's pretend science is a religion, and you choose christianity over science. Well on sunday morning, you wake up, brush your teeth, eat breakfast, and then go to church. The minute you walk into the church you are contradicting your self. Because the church, was not built with christianity, it was built with science. The mathematical, physical, chemical and biological facts required to be able to construct a church demonstrate that science cannot simply be a religion. It is the study of the natural world. Not a religion.

  A comment on Conversation: Read my words and then tell me if science is a religion or not.

  Jul 30 2011: Science could be categorised as a religion, however, no other religion has as many proofs than that of science. Modern science finds a theory, experiments and tests the theory, and then makes a conclusion as to whether the theory fits the phenomena. Most religions are usually passed down over the last hundreds/thousands of years yet science has always been around, developing technology since the beginning, be it a rock used as a chisel or an international space station.
  
  Another important point to consider is: Science is the study of chemistry, physics, mathematics and technology. Religion is not a study but more of a philosophy of life and it's origin.

  A comment on Conversation: My seven year son told me that papa we can attach a hot air balloon to Boat so it does not sink in water during storm.

  Jul 30 2011: It would be an interesting idea but costly and where would the hot air balloon be stored when not in use? Keep an eye on your son he looks like a good thinker though
