Is it possible that the matter that black holes consume is converted to dark matter and energy? I was thinking about hawkings theory about how blackholes eventually evaporate. I thought how can this happen?What if the blackholes evaporation is actually due to its conversion of the matter and energy it has consumed to dark matter and energy.<br />Are there any theories about this. has anyone proposed this at all?<br />Since the universe is composed of more dark matter and energy then normal matter and energy I would think that the conversion of normal matter and energy by black holes to dark matter and energy could account for some things.<br />Can you pick up on this and let me know if my wandering thoughts have any possible value or basis in possible truth?<br />I would think someone would have thought of this, if not why? in basis it makes sense unless I am missing something in my thinking process that I am not aware of, after all I am a newb..<br /> <div class="Discussion_UserSignature"> </div>

Firstly, this forum is for everyone! If you want a personal answer from someone it might be better to send them a Private Message. That thread title makes me feel a little uncomfortable, I must admit!<br /><br />I am not up to speed on the whole of astrophysics and cosmology, just certain parts of it and unfortunately you are asking about the parts I don't really know too much about yet so I will have to leave it to others to field this one. Sorry. <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p><font color="#ff0000">_______________________________________________<br /></font><font size="2"><em>SpeedFreek</em></font> </p> </div>

Black holes are well defined.Whether they exist or not is a theoritical question of General theory of relativity.They may be or may not be dark matter.John Wheler knows.

<font color="yellow">Is it possible that the matter that black holes consume is converted to dark matter and energy?</font><br /><br />It wouldn't really matter what the matter is converted to because the whatever is consumed by a normal (?) black hole will remain in the black hole. And the mass of the black holes do not account for the missing mass or the behavior of the glaxies.<br /><br />PS Black holes take a <i>really</i> long time to evaporate. A mini black hole that has the say the mass of a mountain would take about 20 billion years to evaporate.<br /><br />PSS The 'evaporation' is made up of ordinary matter. <div class="Discussion_UserSignature"> </div>

But if we cannot measure dark matter how do we know for sure that the black hole doesnt expell it? doesnt a black hole eject energy? what if it is also ejecting dark matter and energy? <div class="Discussion_UserSignature"> </div>

How about this for a theory. Assuming parallel universes exist, a black hole in this universe dumps it's energy into a white hole in the corresponding parallel universe thereby conserving mass and energy and doing away with any paradox. <div class="Discussion_UserSignature"> <em><font size="2">Bob DeWoody</font></em> </div>

while I understand the concept of parallel universes I dont get the concept of how a black hole can punch into one with its opposite of a white hole.<br /> When I envision a black hole I see a infinite point on matter that pulls energy and matter and compresses it into itself. Do to its gravitational mass it warps space time, but I cant seem to get the connection to it "punching" into another universe as a black hole isnt a hole at all. <div class="Discussion_UserSignature"> </div>

First I apologize for posting my Q in you thread but I don't see the new post button any where. Again My apologies.<br /><br />Now in parallel to your original question. <br /><br />Members of our species dedicated to science sometimes described space time continuum as a "fabric". <br /><br />Is it not possible that this fabric is the dark matter. <br />If so would make it more probable the existence of wormholes, as in " this fabric is so old it has 'moth holes' in it"? <br />Would it not be more reasonable to appear in another parallel universe through that "moth hole"?

However, the fabric is more commonly thought of as the gravitational field of the universe. Dark matter does exert gravity, so it is a part of the gravitional field of the universe.<br /> <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>

However, for this scenario to play out, there would have been an awful lot of blackholes that have already evaporated, considering that dark matter out weighs normal matter by a factor of 6 to 1. Also, the universe would have had to be at least 10 to 100th power old, for black holes to evaporate completely. Considering the current age is 1.37 to the 9th power. That's quite a (time) difference in magnitude!<br /> <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>
