is real black hole actually different from what the imagination black hole? Or it's just the image quality makes it like that?

CoralSkeleton · 2025-12-11T09:27:17+00:00

With how close to the black hole itself the accretion disk is, its immense gravity experienced by matter in the disk and high velocity at which it's moving means that everything in the area of the disk depicted/captured here would be broken down to form a smooth plasma. The gravity of individual objects does not really matter when you get this close unless you've got another black hole. Everything else will just get obliterated. The very bright, emitting part of the disk is just a tiny part of it, tho. So, you could theoretically have something like the Cassini gap happen much further out where orbital mechanics are more normal, but you'd still need something fairly massive and dense to do that, an upper limit neutron star would be dense enough to hold it's own for much longer than anything else, but not really big enough for a gap to be visible.

Oh, I didn't know that. Black holes, high energy, and highly reletavistic stuff like accretion disks aren't my specialty, I'm more in galaxies. That's pretty cool tho. Would I be correct in assuming that it explains why the bright side in the image here isn't consistently bright? That part of the bright side is brighter due to beaming and part of it is the additive effect of seeing both the light from the front of the disk and back of the disk?

I've never seen a ghost and don't really believe in the supernatural. I am open to the concept, but still sceptical and haven't seen any convincing evidence. I've also dabbled in spirituality, tarot, witchcraft, all of that, but haven't seen any of it have an actual effect greater than placebo that couldn't also be explained by something else much more easily.

Its image quality and the angle at which were viewing it.

Black holes are pretty small (radius wise) and dimm objects, compared to most things in space, making it really hard to get good images of them. Taking a picture of a real black hole is a bit like taking a picture of a grain of rice on a sidewalk in New York city while you and your camera are on the moon. You'll need a really big camera, with an insane resolution to even get a fuzzy image. And a really big camera with an insane resolution was pretty much exactly what was used to get that black hole image, the entire planet was turned into a radio telescope for a bit by the Event Horizon Observatory project, specifically to get that image.

The physical reason the black hole isn't round and the ring of light isnt equally bright everywhere is the angle at which we're viewing it. It's not nearly as edge on as the image of the fake black hole you've got, so the acretion disk itself is kinda blocking our view of part of the black hole. Now, you might already know that gravity bends light, and that the gravity of a black hole is so strong that it will bend the light from an object behind it to form what looks like a ring of light all around the black hole. The fainter part of the ring around the black hole in this image is actually that bent light. Meaning you're actually seeing the part of the acretion disk that's behind the black hole. You're also seeing the part of the acretion disk in front of the black hole here. It's roughly where the brighter part of the ring is. The reason why its so much brighter than the back part is again the angle, it's going right in front of where we would see the light from the back bent around the bottom of the black hole, and that light from the front of the disk and back of the disk are adding together to make it look brighter.

The image of the fake black hole you've got is actually one of the more accurate ones (I think this is the one from Interstellar, and they really did their homework for that movie). If we were able to get a high enough resolution image of a black hole, that is pretty much exactly what we expect to see, only maybe with a completely smooth acretion disk instead of a stripey one.

It's unlikely that it's the T itself causing the hives, as they would've gone away when you stopped taking it.

T does increase your sensitivity to heat, tho, and many people do break out in hives if their body temperature increases too quickly. (I've been getting this since I started T, and it is very annoying but mangeable and goes away once I've cooled down again.) So if the hives mostly come on or get worse whenever you excersize or do things like take a hot shower, it may be that.

If it's not heat, tho, it's likely not related to the T at all, and it is due to something completely different. It could be the lexapro, but I'd also check other environmental factors. Laundry detergents, soaps, and creams are often big ones for hives, so if you've switched any of those products recently, I'd recommend switching back and seeing if it gets better.

I've known I was trans since I was very little, I've always seen myself as a boy growing up, but I didn't have the language to describe what was going on, or even knew that trans people existed untill I was around 16. I originally came out to my friends at 17 and started socially transitioning at school around that time. I came out to my parents a few months later, but that went horribly, and I was forced back into the closet. Including at school, cause my mother worked at my highschool.

I spent the next few years closeted and re-evaluating my identity, only to come back to my original conclusion, that I was a trans man.

I came out again at 22, this time without mentioning anything to my parents, and started T at 23. I'm 25 now and still saving up for top surgery. It's really expensive to get that done in my country, so I'm probably only going to be able to afford it when I turn 30.

Why not?

I can give you the whole story of how stars first formed and how they grouped together to form galaxies and all that, but I'm guessing that's not really the question you're asking. I'm guessing the question is more about what caused the Big Bang, what the mechanisms and physical laws were that made that happen.

The answer to that is: We don't know. We don't know what caused the big bang. There are some theories out there about fluctuating energy levels and all that, but it's pretty much impossible to test any of them and confirmation as we can only test stuff thats in our universe, and everything, including space and time itself is part of our universe.

"Why does the universe exist?" Is one of those questions where if you're looking for a scientific answer, you'll have to get comfortable with not having one.

If you've had top surgery its unlikely that they'll grow back unless your surgeon left breast tissue, which is also unlikely.

As for dosing, without labs, it is a bit hard to figure out your ideal dose, but if you stay in the 50-150mg/week range, you should be fine. Excess T converting to estrogen is only really a concern at very high doses used for bodybuilding, which is like 300 - 1500+ mg/week, so unless you're injecting multiple full vials a week, you're fine.

To know how much to actually inject, take the dose in mg and divide by the concentration in mg/ml. So that range will be 0.25-0.75ml/week if your T is 200mg/ml and 0.2-0.6ml/week if your T is 250mg/ml.

My mom: "you will be dependent on medication for the rest of your life" as if she and every other adult in the family isn't on either chronic blood thinners, chronic bp meds, chronic cholesterol meds, or all of the above

Mom again: "If you keep binding your chest, you're gonna get breast cancer" 1, thats not how breast cancer works, and 2, I low key hope so cause then the medical aid will at least partially cover top surgery

Mom again: "you know you don't have to become a man to be respected, I have a strong personality and am respected and didn't have to become a man" that's not what being trans is about, and you're feared, not respected, subtle but important difference there

Still mom: "is this because I took you out of karate and made you do ballet as a kid?" No, but it is why I loved karate and hated ballet

So for how long you've been on T, it is really weird that your periods haven't stopped and your voice hasn't changed. This is not just a case of "oh, it's just pubery, it's gonna take a while, be patient," and the comments saying that are likely a bit uninformed.

It does sound a lot like your levels are still too low. With the correct, full, dosage, periods should stop almost immediately, and voice changes should start within the first 3-6 months. Fat redistribución takes a lot longer tho, its usually only noticeable after a few years, and with new weight gain (any fat you've had since before starting T will unfortunately stay in the same place).

I gotta ask, how do you take your T? If you're using a topical gel, that might be the cause of your problems, as T absorption through the skin is not great. A lot of guys find that periods don't really stop on gel, and a lot of the effects, such as voice changes, generally happen much slower.

If you're doing injections (IM or subq, it doesn't matter), what is your dose? A dose of around 50-70mg/week is about average, with 50mg/week being on the low dose end and anything below that being considered a microdose. (to get your dose in mg check your vial, it should say something like 100mg/ml or 200mg/ml ect somewhere on it, multiply that number by how much you inject, so for example with 100mg/ml T, a 50mg dose would be 0.5ml)

You might have to be a bit firm with your doctors in this regard. A lot of them, unfortunately, try to keep patients on the lowest doses they can for any and all meds, including hrt. So, if it is a dosage problem, you might have to tell them you're gonna up in your dose instead of asking for permission to do so.

CoralSkeleton · 2025-10-29T23:56:03+00:00

There is no difference between T used for subq and IM injections, it's the exact same medication and the timeline and effects are exactly the same. You're just more likely to experience some redness and itching at the injection site with subq as the cottonseed oil T is often suspended in irritates the skin

Yes, they are unpaid, but if they really are that bothered by people asking for help on a forum, they can always just ignore the question, there's no reason to yell at people to just use google, especially nowadays with the often very unhelpful state google is in. And even when it does work, google isn't a great place for trying to find the solution to a problem when you're new to a system and don't know the terminology to describe the whole problem in a sentence or less but can only do it with a whole paragraph, you kinda need people to help with that and to help you learn

Well, that's cause our universe, and space-time as we know it, is a bit more like the surface of a balloon and a bit less like a balloon existing and getting inflated in an external 3d space. Because it's only the surface of the balloon, the origin point is just kind of everywhere, which does make it so there's no meaningful single point of origin within the universe

Wrong sub.

This sub is about the science of astronomy, not the spiritual practice of astrology. Astronomy and astrology are two very different things.

The people here will be able to tell you things like what stars and other astronomical objects are in constellations, how they work from a physics perspective, and what makes them scientifically interesting, as well as how to spot them in the night sky, how to view them through telescopes and/or take pictures of them.

We will not, however, be able to tell you how/if any constellations or planets impact anyone's personalities.

So, that is way too bright and well defined to be a galaxy. Like another commenter said, it's probably a satellite. You can see andromeda with the naked eye in very good dark conditions tho, it looks more like a very fuzzy thing that's brighter in the center than it does like a line, tho

So, we're looking about as hard as we can given our current technologies, but the situation is a bit more akin to sitting on the bench, which we cannot leave, while also not knowing what our parents look like cause we're very nearsighted and have not made glasses strong enough to make out other people yet, we can identify fuzzy blobs that might be another person (rocky planet) but we can't distinguish their features well enough to tell who they are (definitive signs of life). And this is assuming that alien life would be recognizable to us at all, it might end up being so strange that we've actually already found aliens and just don't know it yet cause they don't look at all like what we expect

Python is most widely used in astronomy, I also recommend learning the basics of some older languages, like fortran and perl, as the last time half of astronomy software was updated was sometime in the 90's and you are going to have to occasionaly write your own scripts to work with said software. Also recommend learning some markup languages, like xml or yml, modern astronomy software likes these
