Is Our Universe a Black Hole?

Click For Summary

Discussion Overview

The discussion revolves around the concept of whether our universe could be considered a black hole, inspired by ideas from inflationary cosmology and the holographic principle. Participants explore personal reflections on their discoveries and realizations in physics, as well as the emotional responses to finding that their thoughts may not be entirely original.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant shares a personal realization about the similarities between pockets of space in inflationary cosmology and black holes, suggesting that the universe could be a black hole.
  • There is an emotional response to the realization that some ideas may have already been explored by scientists, leading to feelings of both excitement and disappointment.
  • Several participants reflect on their own past experiences of thinking they had made unique discoveries, only to later find out those ideas were already known.
  • One participant mentions the anthropic principle, arguing that our existence influences how we perceive the universe as being tailored for us.

Areas of Agreement / Disagreement

Participants express a mix of personal anecdotes and reflections, but there is no consensus on the main topic of whether the universe is a black hole. Multiple competing views and interpretations are present, particularly regarding the emotional aspects of discovery and realization in the field of physics.

Contextual Notes

Participants' claims are based on personal experiences and interpretations, which may not align with established scientific consensus. The discussion includes unresolved emotional responses to the nature of discovery in science.

So, yeah.

Here I am, a fledgling Undergraduate Freshman at Brigham Young University. I've been reading Brian Greene's books, and darn, do I love physics. This was the semester I decided to change my major from Mechanical Engineering to Physics-Astronomy.

Well, one night, as some of this stuff was going through my head, and me and my roommate had gone to sleep at an unusually early time (that is, about 4am), something came to mind.

Something that I had always been fascinated by was Inflationary Cosmology's insight on how a pocket of space could drop Higgs field value and creating an expanding volume of space with dropping Higgs value, resulting in a pocket of space with limited spatial extent from outside, but expanding eternally, that could have infinite volume from inside (Heh, has it ever occurred to anyone that this bears some striking resemblance to the TARDIS?).

I had wondered what these pockets of space could look like should such a situation occur in our own universe. I wondered about black holes. That's when I made the realization - that the more I thought of it, the more it seemed to match up.

I literally sprang up in bed and showered my roommate with my excitement, frantically jotting down notes. Everything that ever fell in would, from the inside, appear to suddenly appear at the beginning - like the big bang, I wrote. Time's arrow would be towards the center of the black hole from outside, and that our universe is a black hole would be the basis behind the whole holographic affair (where the amount of information in a volume of space is related to the area of that region, not its volume), and how a certain matric works out so a trajectory of imaginary dt and dx result in the two (space and time) swapping roles, Etc, etc, etc (not suggesting these ideas here, merely stating that these are the things I was thinking of and writing down at the time).

I was afraid to mention it to my physics 123 professor, though. So I hesitantly kinda sneakily asked about how these pockets would appear from outside, and kinda tried to steer the conversation in that direction. Thing is, who am I, to come up with something great? I'm just a college freshman. I was really scared to say something as audacious as "I have a groundbreaking idea," I was sure that if I did, it would be met with a great deal of - well deserved - skepticism of a very condescending variety.

That was a few months ago. I'd decided to wait until I have more mathematical tools to explore such ideas. But funny thing, I've just been reading that apparently I'm not the first to make these connections. And apparently some of these realizations that just kinda happened for me, are actually things that scientists have already discovered .

It leaves me in a really funny position, though.

On one hand, it's "Holy guacamole, I really am brilliant!" so it's kinda cool. But on the other, it's: "Well. So much for my hopes of becoming renowned in the field for making an amazing connection and discovery far above my academic level," which is kind of a killjoy. Kind of, as in a lot of, haha.

In the end, though, I'm left with: "Well, I can come up with things, so maybe next time I come up with something that I bounce on the bed at 5am for, it'll be something someone else hasn't beat me to."

I'm really posting it here, though, saying it's left me with an odd mix of emotions.

How often does this kind of thing happen in the professional field, where you're left simultaneously thrilled and completely shut down?

Perhaps this mix of emotions is proof of the Many Worlds interpretation, since both exist simultaneously yet seem mutually exclusive, haha :rolleyes:

I lost count of how many unlocked doors I have pried open in my life.

Beautiful moment in the Dr. Who finale, where you've got a room full of brilliant time-travelers who've conquered all kinds of demons and empires, saved entire worlds and done the impossible, and they're locked in a prison.

They devise this intricate plan using a device with them, to leave it by the door, scanning it for hundreds of years to find the resonance pattern for the oak wood, and put it on a subroutine, then using some time-travel trickery, they'd have it already in their possession, and just when they're about to execute this plan, someone walks in: the door was unlocked the whole time.
 
I always carry a set of locksmithing tools in my book bag, just in case.
 
In high school I thought that (n+1) choose 2 = (n+1)n/2 was an revolutionary discovery.

Hey, I discovered it 2 years ago. That's the sum of the famous sequence I always thought about when I was a child: What will you get when you add all the numbers between 0 and 100? (Including 100)
I guessed and got that formula. I was so happy then.
I later discovered that there's a formula for doing that taught in A-levels. :redface:
 
When I was eleven my Mom got me the awesome book "A Short History of Nearly Everything" by Bill Bryson. I was totally hooked and read it through in a matter of days.

At one point the author wrote that the Earth is in at a very lucky distance from the sun. If it were even a little more nearer or further away we humans would not have evolved. He went to great lengths to show how "lucky" we were, writing that Moon also should also be a particular distance away etc.

I thought about this and decided that the author had it backwards! Since we humans have evolved we shouldn't be surprised to see that our surroundings appear to made just for us. If this weren't the case, we wouldn't be alive to ask such questions in the first place!

For some strange reason I thought that nobody but me had ever thought along these lines. (Perhaps I thought Bill wouldn't omit something so obvious from his book) I remember feeling really happy and trying to explain my "discovery" to my brother. I forgot all about this after two hours of video games of course :rolleyes:

Then a sometime back I found a link to http://en.wikipedia.org/wiki/Anthropic_principle here on PF
