I’ve been meaning to explain my black hole hypothesis for some time now but there is always something more important to do. But David and Say Uncle posted about it so it’s time I elaborated.
I tried to leave a comment on David’s post last night but the blog software rejected it as spam. David posted my comment in a separate post a few minutes ago. Here is the comment:
Actually my hypothesis was formed almost exactly 1.5 years ago.
See here and here.
I did a little bit of math on the topic but to say my cosmological math is weak would be a gross understatement. What results I did come up with seemed plausible though. That is–the “background radiation left over from the big bang” appears to have a similar temperature to that of the event horizon of a black hole composed of all the matter of our known universe.
I recently listened to the book Parallel Worlds and was surprised and pleased to hear that others had explored the same hypothesis–at least part of it anyway. No mention was made of the direction the black hole being on the time axis. This is a critical component and the easiest thing to prove as being consistent with the known facts.
I will now elaborate further.
My first “Ah hah!” moment was back in February of 2009 and I posted a couple of Tweets about it:
I’m listening to The Black Hole War. This inspired me to explore the hypothesis that our universe is a black hole.
We are rushing toward the singularity at the speed on light on the time axis.
Since then I have made casual references to my hypothesis on my blog (here, and here) and I think a comment or two on other people’s blogs.
Our experience with time dilation and length contraction is the best support for this hypothesis. Starting with the equation for time dilation we can rearrange it as follows (brother Doug pointed this out to me a couple decades ago, I have not read or heard it expressed this way before or since so a great deal of credit, or blame, for inspiring this hypothesis goes to Doug):
DeltaT’ = DeltaT/(SQRT(1 – v2/c2)) Where DeltaT’ is the elapsed time for the moving, at velocity ‘v’, object and DeltaT is the elapsed time for the stationary observer. ‘c’ is the speed of light.
SQRT(1 – v2/c2) = DeltaT/DeltaT’
1 – v2/c2 = (DeltaT/DeltaT’)2
1 = (DeltaT/DeltaT’)2 + v2/c2
c2 = c2 (DeltaT/DeltaT’)2 + v2
c2 (DeltaT/DeltaT’)2 is the square of a velocity. Hence we could substitute a symbol for this expression. Let’s let ‘t’ = c (DeltaT/DeltaT’).
c2 = t2 + v2
What this says is that as a moving objects velocity, ‘v’, increases the velocity ‘t’ must decrease such that the sum of t2 + v2 remains constant. This gives us time dilation. But what is the less obvious observation is that as ‘v’ goes to zero our velocity in the ‘t’ direction becomes the speed of light. Hence stationary objects in our frame of reference are actually traveling in the ‘t’ direction at the speed of light.
Inside the event horizon of a black hole all objects travel at the speed of light. If they move off of the straight line toward the center of the black hole the sum of their velocity components still must be precisely equal to the speed of light. Hence if they take on a velocity vector perpendicular to the straight line to the singularity they move slower in the direction of the singularity. This is exactly our experience with time. Our time “velocity” decreases when we increase our velocity in any other direction. Hence, I hypothesize that, we are inside the event horizon of a black hole moving toward the singularity which happens to be in the direction of the axis we call ‘time’.
Further support for this hypothesis is length contraction. We know that as the velocity of a moving object increases the observable length (it doesn’t actually contract, only observations of it’s length decrease) of an object decreases. At the speed of light the length of an object is zero (I suspect it actually becomes the Planck length, but this is just a guess on my part). Since we (according to my hypothesis) are traveling at the speed of light on the time axis we can only observe a single instant of time.
Of course the first question that comes to mind is, “When do we get ripped apart by tidal forces and our subatomic components get sucked into the singularity?”
I don’t know the answer to that, but it is something to think about isn’t it?
Have a nice day.
