I have been teaching myself physics, as I can’t afford to take a course at the moment. I do have a lot of ideas on things I have read however.
Ok, now as far as I understand all gravity bends space, and attracts more mass.
so a black hole is an extreme curve in space when there is a huge amount of gravity, so that would mean that black holes will eventualy consume everything in the universe, and when there are say 1,000 blackholes left, the larger ones will devour the smaller ones. Once this is done there will be one black hole which has consumed all mass and space.
as soon as all mass and space is consumed, then it will have all the room it will need to expand once again.
Is it possible for the universe to be in flux like this?
I am not a astrphysicist, however it seems that your conclusion are a bit extrapolated. I’ve never heard of such a thing as black holes eating all the matter of universe ?
I must have miss understood, I was under the impression that blackholes (because of the intense pull) continued to consume and as they take in more matter they would become greater as more mass would be attracting more mass.
Though it would make sense that they don’t since the universe is still expanding.
Hawkins’ renounciation of his blackhole equation is the last news for me, also it’s said that that new parer of his wasn’t met with general acceptance and imression from the world academia. I wonder is he trying to come up with a new math prove. So what’s the latest?
based on our understanding of physics, here’s a list of ways the universe might die (not complete) :
termic death : since substances of different temperatures will interact by reaching a mean temperature, eventually everything will be at the same temperature. since work can only be done by moving heat from a hot source to a cold source, there will be no more work done. everything will be at peace (=death).
the spontaneous creation of matter-antimatter pairs seems to render this void
mass concentration : since the bigger a mass, the more mass it attracts, everything will end up clumped together, and time will eventually stop (=death). some like to say that it explodes back up then etc. it’s possible, after all.
[got bored listing them]
anyways, point is, we don’t really know enough about the universe to be able to give this sort of estimates. it’s really an exercise in “well my daddy pays me 20 bucks weekly allowance, and all the money i ever saw in his hand was 200 bucks 1 month ago. therefore he will be broke in 6 weeks and my allowance will stop”. maybe so, but wouldn’t hurt to look at bank accounts.
These forums a philosophical, so therefore you might get peoples intepretations of what a Black Hole actually is. It is not really a good place to ask questions about scientific thoeries. My idea of a black hole goes against all of the scientific explenations so I will not confuse you with it here, but I just wanted to warn you that I could have.
My understanding of why this cannot happen is as follows. While black holes contain an enormous amount of mass, the extent to which they distort space and time is dependant on the inverse of the distance from them squared. So, when you are a very long way from a black hole, the gravitational effect from this black hole will be very small. A very distant massive object will still ‘feel’ an effect from a black hole (however small) but it is likely that the postulated expansion of free space will overpower such a small attraction.
well you have to take into thought that a black hole is the void where a supernova exploded. Thus leaving an enormous amount of mass condensed into a tiny space. The gravitational pull is strong enough to pull light into it. Thus given the name “Black Hole.” From what I know, you are pulled into a form of “Singularity.” I would think that after its pulled enough things into it, it will slowley grow into a physical state the black hole would dissolve.
Black holes are most likely something entirely different than what we think right now, though it may be a while before we see what that is. Gravity has long been sort of a mystery, and most of the theories that stem from general relativity rely on the assumption that Einstein’s equations were right in the first place.
Everyone gets proven wrong eventually in science, it’s only a matter of time before we see his fundamental flaws, and expand on theories like shadow gravity and alternative stuff like that
Perhaps we should first analyze the causes and effects of gravity before linking them up with black holes.
Let’s first imagine space (or space- time) a a piece of cloth, matter as snooker balls on that piece of cloth. The ball (the objects) makes depressions in the cloth when they are on it, in other words, the cloth now has a depression in it. This depression can be interpreted as the curvature of space-time. This curvature would cause things to fall into the object causing the curvature. The more massive the object, the greater the resulting curvature. In theory, this curvature would extend to the bounds of the space-time cloth (the universe), however, the further they get, the more negilible their effects. For example, an earth would cause space-time curvature, but its effect is negilible when you are, say, 30 AU away.
Black holes are matter compacted into a really small volume, some postulations even claim that they are compacted into a singularity, this great amount of mass would cause a great degree of curvature. However, the curvature produced by a black hole is very regionally-confined. If the sun is suddenly compacted into a dense insingularity, earth would not suddenly be pulled into the sun but would orbit this singularity as though nothing occurred (assuming the mass of the singularity is the same as that of the sun). The gravitational effects of a black hole only becomes noticiblely different from an object of the same mass, but not compacted into a singularity, when you are at close (in an astronomical sense) proximity.
Therefore, black holes would pull on things with a great gravitational attration, but only at a certain proximity, otherwise, its gravitational effects would not be noticiblely different from an object of the same mass. So it seems quite unlikely that the hole universe is going to be pulled into one single black hole, especially when the universe is expanding.
Hey Sydon,
From what I understand the idea you propose is that matter into a black hole is a one way process, so in any system containing a blackhole it will eventually eat everything, therefore in the end there will only be one massive black hole(?).
Yes this is possible, but with the universe expanding it becomes of a problem for a blackhole to get round everything. Going through the science, blackholes give off energy via hawking radiation, I can’t recall if this will limit a black hole by ‘evaporating’ it faster than matter goes in for objects of the size you discuss.
Secondly a Blackhole is contained by its own gravity, not any kind of outside pressure, so there won’t be an explosion (big bang style) if there was just 1 blackhole containing all creation.
