Science Talk and Theories
Lets have deep adult talk about science and the universe......
Here is a theory I have been sitting on for a few years: We all the know that the universe was created by the big bang. We also know, and it proves the big bang theory, that the universe is expanding. Well....what if the universe is like a sign wave. As in the Universe expands till it reaches a limit, then starts to collapse back to the point of the big bang and keeps repeating this forever!?!?!? What if the dark matter that we can now detect is actually left over matter from the last collapse wave?!?!? |

The expansion seems to be slowing, and if it contracts we don't know what happens at maximum contraction.
I've always been intrigued by the multiverse theory that universes expand and collapse all the time like bubbles. But here's a tweak, it's possible these aren't bubbles isolated from each other but blend and cross a dimensional spectrum we don't understand completely. So you could have an alternate universe sitting in the same room with you but you don't have the senses to see it.

ETA: Here's a NASA article dated 2019 that discusses the increasing expansion of the universe based on data collected from Hubble: https://www.nasa.gov/feature/goddard...ew-hubble-data |

All im saying is what if, on the collapse side of the universe, the dark matter is needed or created?? Right now we can feel the gravity of the matter but it wont appear till universe stops expanding and starts collapsing. I have no math for this, I have a engineering degree and watch/read too many science shows/time travel movies/etc. |

I always thought it was slowing down? Apparently they revised that observation. In any event if it's accelerating then we don't know if it will just keep going to contract yet. But if the behavior of our universe is similar to other phenomenon I'd expect it to slow then contract.

I suppose in the vacuum of space with no gravitation drag you could accelerate forever. That's not out of the question. But, supernovas explode and contract, so maybe the same situation evolves for the universe expansion?

That's due to the gravitational effects from what is left over after the star in the center explodes. But this is all localized. This still doesn't negate the resulting celestial bodies are still moving. The formation and death of stars are still occurring in our own Milky Way galaxy yet the Milky Way and our nearest galaxy, Andromeda are on a collision course with each other based on current trajectories.

Matter doesn't get stretched because it's accelerating. The only phenomena I'm aware of which causes stretching or the other term which is spagettification is what happens when matter falls into a black hole (singularity). And even in that crazy environment where the classical laws of Physics don't really apply anymore, matter doesn't spontaneously change into energy. Based on my understanding.

I'm personally a fan of the simulation hypothesis. By fan I mean it's just the one that makes the most sense to me as a lay person. I mean just look at all the weird shit going on in the quantum world. Don't tell me that shit doesn't sound like this whole thing is being simulated.
I was listening to some interview with some guy the other day who hypothesized that everything we see and interact with are just representations of some much more complex underlying system. The way we have icons on a computer screen which represent certain complex functions that happen internally on the computer which we are unaware of. It was pretty interesting... not totally sold on the idea but fun to think about anyways. Also think about the difference in intelligence between us and say a chimp, the closest animal to us. A chimp can't even begin to comprehend space, or mathematics or anything like that. Not even the smartest chimp. Now imagine just that same difference in intelligence between us and some other species/entity/whatever. It could be we are simply not capable of the intelligence or sense or whatever to really ever understand the inner workings of the universe. |

To think that we are the only intelligent species in the universe is probably the dumbest thing you can think or say. Why haven't other intelligent species visited us? Lets start a side conversation about that: 1. They already have in the past (many cave drawings in the past along the equator all over the world that shows they have) and have set us on the right path. They may visit us again if we get off the "Right" path. 2. When you driving in your car at 100 Km/h, do you stop to look at the ant on the side of the highway??? No! So we not there yet for a visit. I think one day we will have footage of a earth in a nearby galaxy. We will then see how far advanced we are or are not! |

NDTyson speculated once that our brand of space travel may not impress alien intelligence much because it's still based on basic physics. But if we started moving around dimensionally they might look at us differently.

Or if we do have the capacity to ultimately understand the inner workings of the universe maybe that's game over. Maybe once we do they turn off that computer. |

Get the Ebola virus to be come airborne like covid and its game over! We as humans really need to start thinking about reducing earths population. 1 child limit would be a good start. Im sure if we melt enough of the perma-frost it will release some crazy wild viruses. |
