comment Is dark matter really matter?
@Manishearth and lurscher: so in other words, if you held a piece of dark matter in your hands, you would touch/feel it but not see it? Strange world we are living in :-)

@Manishearth: can you say that everything that interacts with electromagnetism is stuff you will be able to see? Is electromagnetism a reqirement for things that is going to get visible?

@Manishearth: but dark matter does not emit photons, right? Does dark matter absorb photons? If it is the gravitational force that absorb the photons, why cannot we see the dark matter?

comment How does matter transform into energy and vice versa?
Thank you for your answer! I was thinking about splitting up things, is it teoretically possible to split a neutron, electron and other particles smaller than an atom? What would happen? Even more energy?

comment Questions on wave-particle duality
I find it so difficult to accept that the wavelenght function of a particle constricts when trying to measuring it. :-) Sounds so magic! :-) That should mean that our mind (which consists of electrical particles) is quiet random as well, because we are not observing our mind. :-)

comment Questions on wave-particle duality
@Manishearth: caveman said above: "An observer is simply defined as something that increases the entropy of a system". A sound recorder does not increase the entropy of a system. If we put a sound recorder nearby the tree, we should notice if there is a sound or not afterwards when we check the tape. I guess caveman is wrong in his definition of what an observer is?

@Manishearth: What makes the particle´s wave constriced when observed? Does it exists an answer on that question or is it a mystery?

When does the probabibilty overgo to either the one way or the other? Or maybe that is unknown?

comment Questions on wave-particle duality
But what I have read, a particle's wave properties disappear when trying to measure the particle´s path. So the interference just happens when nobody is "wathing" the particle.
