Yes. I'm a guy, and I would love to get a girl's take on this.
Do you think Fermi's "Great Filter" is not necessarily that a civilization destroys itself, but that it discovers a way to destroy the Universe?
Like, maybe the fabric of our reality is more fragile than we realize, and the reason we don't see "aliens" is that the universe doesn't get old enough for intelligent life to meet.
Of course, this assumes we are in a statistically "average" Universe, since presumably there could be a Universe in which intelligent life co-evolves within the same solar system.
I've always felt like a lot of the assumptions in Fermi's Great Filter feels off. Like, the way we talk about "intelligent life" feels iffy, both in astrophysics and other fields. I'm not great at articulating this, but if you're one for video essays, Dr Fatima Abdurrahman recently made a video that captured much of what I'd struggled to say on this.

No pressure to watch the video, especially as not everyone enjoys consuming content in that form.
Anthrocentrism is part of what I mean, especially if we consider that historically, colonialism has had a lot of power to draw the line between who "counts" as fully human or not. A depressingly common motif is the cyclical logic of "this is what we understand human intelligence to be" -> "these people do not have the signifiers of human intelligence that we understand" -> "therefore these people aren't intelligent" -> (those people are less likely to be considered as the general understanding of 'intelligence' expands and evolves).
Personally, I think you're really close to the answer but with an important distinction. The great filter is an hyper aggressive species that does not want to deal with a potential cold war with a different species with technology as advanced as their own. They already launched their doomsday armageddon weapon at us after detecting our existence, probably from something like our farthest satille, Voyager 1.
It could take generations for the bomb heading to our sun or stealth asteroid heading directly for us to actually connect. But it's arguably in their best interest not to even chance us becoming militarily on par with them.
Statistically there is alien life out there somewhere, and whichever one got to interplanetary weapons first would have everything to lose by allowing an equal to exist.
My question for you is, why do you want a female perspective on this? Idk, doesn't seem like something that gender would effect.
Phew okay. In that case, I do agree that a hyper-aggressive species could be the Filter, though it's worth noting that our radio signals have actually reached further than our furthest probe, so I would go off that when doing round-trip destruction calculations. I love Mass Effect's take on this idea (though I haven't played 3).
As for why I asked women: Mostly because I thought the non-sequitur was funny.
You mean like what if species at a certain level of development start fucking around with zero point energy and trigger false vacuum decay?
Actually it's entirely possible it's already happened. There are lots of galaxies so far away their light will never reach us if it's emitted now, and vacuum decay travels at the speed of light AFAIK
That's exactly what I mean. Like, even if a civilization set out at near-light speed a long time before triggering a vacuum decay, the decay would just catch up to them and wipe them out before they could reach us. It's a theory absolutely rife with holes, but it's an interesting possibility.
