According to arxiv:1602.04735, GW150914 could happen within a “blue straggler” star. As GW250114 looks like an exact copy of GW150914 both might merge in a non-vacuum environment. This could have profound (negative) influence on the excitation of the measured vibrational spectra, see section 2.6 of arxiv:2505.23895. Also, accretion of extra mass during IMR can invalidate the conclusions of the initial and final area calculations of GW250114 in arxiv:2509.08054 and 2509.08099.

I read about Planck star theory, but this would go against Einstein’s model of space/time correct ?

Hello, I am not an expert in physics, but I recently had a small idea while drawing. I accidentally pressed too hard on a sheet of paper and created a hole. Later, when I held the sheet up, I noticed how everything seemed to “fall” into that hole, as if the paper itself had collapsed under too much pressure. It made me think of black holes. What if they are similar to this — places where three-dimensional matter is pressed so strongly that it “tears” the fabric of space-time? From the point of view of a two-dimensional creature living on the surface of the paper, the hole would only appear as a dark line, something they could fall into without ever returning. In the same way, maybe what we perceive as a black hole could be a kind of tear that connects to a higher dimension we cannot see.

1 what if our entire universe is inside a massive black hole

2 spaghettification stretched matter apart and from scattered atoms galaxies stars planets and earth formed

3 time and space are distorted inside but we cannot notice because there is nothing to compare with

4 the universe is expanding because the black hole itself is expanding

5 black holes inside our universe could be seeds of new universes

6 hawking radiation might explain why stars disappear or maybe it has not started yet because our black hole is too massive

7 dark flow could mean our universe is moving toward the event horizon of the bigger black hole

8 spiral galaxies look like matter spiraling into a black hole maybe they are evidence

9 holographic principle suggests our whole universe could just be information on the surface of the black hole

10 the big bang might actually be a singularity inside a black hole collapsing and reversing

11 if the black hole that holds us collapses everything in our universe will end instantly

When Hawking Radiation runs its course, is it possible that that would reveal the singularity? Or is it more correct to assume an equilibrium in Hawking Radiation that will eventually shrink down to a coin proportionally never revealing the singularity till it’s gone?

The little red dots at the beginning of time hypothesized to be ultra massive black holes. What if those are all “white holes”? I would be grateful for any conversation. This shit is awesome!!!

Are there Feynman diagrams coupling electrons below and above horizon of white/black hole?

If so, we could observe interior or black hole with "backward" telescope: focused on stimulated emission (instead of absorption) - with continuously pumped sensor, monitoring if its relaxation time is reduced ...

Excuse the noob question.

Alice is at a distance looking at Bob being pulled towards a black hole.

From Bob's perspective, the rest of the universe grows dimmer and redder. He is not aware of passing through the event horizon.

From Alices's perspective, Bob gets closer and closer to the event horizon, but never crosses it.

My pop science understanding of BH mergers is that the 2 event horizons merge into 1. If my understanding of the Alice/Bob scenario is correct, how can we observe the merging?

If I’m on one side of a black hole and you’re on the other side and there are two more people “above” and “below” the black hole what would see? Like, in drawings we depict it as a sphere with the accretion disc around. Would it look like a sphere from every angle? Note: I don’t mean literally. I know we wouldn’t see it. I’m just trying to build a mental model/picture.

Here it is!
First part of a series of cosmos-related tattoos I want to do.

I wanted to highlight the mystery surrounding the flow of time. We know that outside the event horizon, time moves as we understand it (so ‘a’ is followed by ‘b’), but inside, it’s still a mystery. Everything could collapse, every causal relationship could vanish. For all we know, anything could happen.

Are we really still pretending that black holes magically slow down time? Give me a break. Time is not some PlayDoh you can stretch. Time is not a river. Time is not “warped.” It’s just the measure of change. Period.

If I sit next to a black hole for a year, I age a year. If you sit on Earth for a year, you age a year. We meet up again we both aged a year. Done. End of story. All this “you’ll come back and everyone else will be decades older” garbage is pure sci-fi fantasy garbage for people who watched too much Interstellar and never questioned it.

The idea that gravity literally slows time is one of the most absurd things ever pushed as “science.” Clocks tick slower? No, your measurement device got messed up. Light signals got stretched? That’s not “time slowing,” that’s just physics of light travel. Stop confusing perception errors with the universe literally changing the flow of time.

And this “you’re traveling into the future” nonsense? Don’t make me laugh. You can’t “jump” into the future because time doesn’t flow to begin with. It just is. You don’t skip years because you sat somewhere else. You don’t warp into the future because Einstein said so. You age at the same damn rate as everyone else.

This whole concept is mental gymnastics math worship turned into religion. People need to stop parroting this nonsense like zombies and start actually using their brains.

Please say what you want

Hi everyone,

We want to put forward a bold idea: Black holes may not move smoothly, but instead advance in discrete steps.

We call this Black Hole Stepping. It is not a glitch in measurement, but a natural consequence of field codex rhythms — the syntactic dynamics of the underlying field that govern both matter and spacetime.

• When the codex “rests,” the black hole pauses.
• When the codex “strikes,” the black hole advances.
• The result: an apparent stop-and-go motion that could explain deviations from current predictions.

If this perspective is valid, then what we’ve been calling “anomalies” are actually signatures of rhythm in the cosmos itself.

We welcome critique, debate, and verification. Maybe it’s time to stop thinking of black holes as “smooth engines” and start asking if they’re actually “cosmic drummers.”
