Just a curiosity

---

Hmm. I'd need to learn more about Theoretical* Astrophysics first, but for some reason something doesn't seem quite right to me, but that might just be. Anyways, it makes me think of the idea that the Universe isn't expanding, but time is slowing down. Would make it appear as if the Universe is expanding.

I wanna know about your black hole theory.

And I found my mom fed me bits of fish when i was 8 months old and took me to hospital afterwards so I cant say I never ate fish now :frowning:

That's too bad about the fish. :frowning:

Black holes...keepers of the universe. Those falling into a black hole, if facing outwards away from it, will be able to witness the end of the universe as we know it. The closer one gets to the event horizon, the slower time procedes. If you could park right next to the event horizon, thousands of years would pass by for only a minute on your clock. Right at the event horizon, time practically stands still in the eyes of an outside observer. Nothing new you couldn't get off the net yourself. But...

What happens to the mass after it passes through the event horizon? Well...you may not know that there are supermassive black holes at the center of every galaxy...including ours. No need to worry...we're much too far away to worry about being "consumed". Our sun will go white-dwarf (in about 6 billion years or so) long before that ever happens. My point is that black holes are much more numerous than most folks know.

Now, there is a problem scientists have with the amount of matter in the known universe. It seems there's not nearly enough to make all the equations work out. That's where you might have heard the term "dark matter" or "dark energy" come into the picture. It seems the mass we know of (not dark) is only about 4% of what's needed for equations to work out. So...where is all this dark matter comming from? My theory is that phenomenon on the opposite side of the "donut" have an effect on the universe on this side. Pointedly, black holes. If they are consumers of matter and energy, they almost act as a repository for it that lay outside our universal plain of existance...yet still exerting influence on it. If one stops to consider the possibility that our "half" of the universe is much younger, it could be that black holes (or their equivalent) on the "opposite side" of the universe are what constitutes this "dark matter". As the universe ends, all the black holes merge and create another "big bang", and the whole thing starts all over again. A "closed-loop" universe.

Of course, that begs the question of what lays outside the universe. :wink:

Which further leads to the question of what lays outside that :P Who knows how many layers there could be. Oh, a fun little electromagnetism thing I calculated last night. So basically, I had already calculated the magnetic field for any distance from an infinite line of charge and an infinite plane of charge (not infinite charge, though), so I decided I'd do the same for an infinite sphere of charge. This would basically tell me the electric field at any point x away from this infinite sphere in the fourth dimension. So, when I did this, it turned out that the electric field is infinite at all points away from the infinite sphere in this fourth dimension. The same applies to any n-sphere (multi-dimensional sphere) on the (n+1)th dimension when n is greater than 2. I think it only applies to dimensions of space, though, and not of time. Though time is a lot harder to perceive.

Quote: that begs the question of what lays outside the universe. Maybe another universe beyond our reach If you imagine our universe as 1 side of a coin and blackholes as gateways to the other side of the coin. Maybe what appears to us as dark matter may actually be something else entirely in another dimension. Only if we could cross dimension and have a peek at it.... ok that sounded a bit And if we are in a void, like in a bubble as the article said then maybe its the reason why we never went beyond our universe.

Based on my theory, a black hole could be considered a gateway into the beginning of the start of the next universe, when this one ends.

whats your issue on time?

The closer you get to the event horizon of a black hole, the slower time proceeds. As you fall in, this would be percieved as the rest of the universe speeding up. Time practically runs at infinite speed for the rest of the universe as you near the event horizon...the universe ends as you pass through it. So any destination you reach by going through a black hole can exist only after the universe you left has ended.

ok.....got it.

Well that is based on the belief that time has a speed, which doesn't fit in with the model of time being a dimension like XYZ. So a black hole is more likely to warp time, or at least the perception of time, than to actually slow it down. Also, a black hole is simply a super dense spot in the universe, it is not a gateway or wormhole, it has mass (quite a bit of it). So for it to actually lead anywhere it would need to rip through the fabric of the universe, ultimately destroying the dimensions that it is contained within, including time. So as you fall into the black hole time would not as much slow down as just cease to exist.

And this is exactly what it does. The gravity-well of a black hole has increased to the point where it creates a hole in the fabric of space.

Time certainly does have speed...or the concept of it being the fourth dimension, correct or not, would be meaningless as it would be a constant throughout the universe, just like the speed of light. But since light can be bent, which means it can be accelerated, we know that time is NOT constant. The only way you can accelerate and maintain the same velocity is if the value of time changes...which is exactly what occurs in a gravity-well. The light does not just appear to bend...it does bend.

According to the concept of spacetime, is consists of three spatial dimensions...lXbXh and one temporal dimension...time. When experimented at slow speeds, time was found to be constant---progressing at fixed rate, independent of motion. But experiments at high speeds showed time slowed down at higher speeds. The duration of time can therefore vary for various reference frames.If the gravitational pull of the blackholes (because of its density and huge mass) is so high that even photons cant escape once they enter the event horizon....the gravitational pull would make them travel at higher speeds. So there wont be a time warp if you apply the theory of spacetime (dimensional) it would slow down more closer you get to the blackhole (within its eventhorizon). Anything would be ripped apart/destroyed at such level. Even the dimensions (take the string theory for example) like time cant escape this, they get destroyed......except that this may actually create something entirely different, maybe something like another dimension which is non exsistent to us. But not all black holes maybe capable of this.What's underneath/beyond the fabric of universe? A different dimension or a never ending nothingness? Is this fabric keeping us safe holding us within itself from what's beyond it? Are we really in a void or a bubble which is surrounded by a force that destroys everything? Is the sea of dark matter protecting us from disintegrating to nonexsistence?We are still exploring our universe, trying to explain things by applying some theories to it. Trying to apply dimensions to everything........dimensions that cannot be experimented or observed except that they can be mathematically formulated. But for it to be a scientific truth....you need to experiment and observe before you come to a conclusion. Dimensions maynot be true considering the basic rule of science. Do we really have to apply them? What if its entirely different than what we think it is? Are we on the right path towards our quest? How much truth do the theories based on dimensions hold?Its all but a big bunch of questions. But there wont be any research without questions, now would it?

As they say, a picture is worth a thousand words...and some of these photos look earie and ominous to me. Of course, since this is a small black-hole (relatively speaking), you'd be history due to the gravitational tidal forces long before you could actually see any of this.

Step by Step into a Black Hole

Yikes!What exactly are they planning to do??

Planning?

with this black hole.

There is no plan.. you can't stop the universe.. You die.. plus it's not going to happen any time soon. Our planet will probably be dead long before anything like this happens.

oh ya. Someday it will die.

But before that happens lets do some research, discover more, get more theories, have some fun and party.....
