All Things Space

[MARTIAN]

The entire universe is just a gigantic metaphor for the reality that you create or want to create in your mind, the entire universe is not really physical, as long as you keep looking it will continue creating itself, but it is you who keeps creating it... peace!

This is cute

black holes exist and it isnt in question.
im 99% sure they proved it a few years back. i will provide links if i can dig them up.

edit = i see someone already showed you pics. i know they have seen blackholes swallowing stars.
when the hole swallows a star too massive that is when the hole starts spitting out the radiation someone mentioned.

i dont think it is cosmic background radiation but some other type. it can be detected across the entire universe.

I'd love to see observational proof of something disappearing into a black hole. Random pictures of things in outer space prove nothing without explanation unfortunately. There is Lot of weird shit out there.

And yes there is a question when the only evidence for something is theoretical math that includes things like dark matter that isn't understood at all yet is essential to said theoretical math.

The math works. Show mW something disappear now.

I think black holes are out there BTW...but there are still questions.

black holes were up for debate in the 60's and 70's. these days the smartest people on the planet have come to accept them as legit.

this is from wikipedia and it describes the radiation i mentioned.

"As such many of the universe's more energetic phenomena have been attributed to the accretion of matter on black holes. In particular, active galactic nuclei and quasars are believed to be the accretion discs of supermassive black holes.[95] Similarly, X-ray binaries are generally accepted to be binary star systems in which one of the two stars is a compact object accreting matter from its companion.[95] It has also been suggested that some ultraluminous X-ray sources may be the accretion disks of intermediate-mass black holes."

Any word on what cause The Bootes Void or what is inside that big emptiness. Is there dark matter there. Can we send a probe there to collect stuff there.

Its hard to take your criticisms seriously when you dont understand the math or the evidence.

Its about 700 million light years away from us.. So no we wont be sending probes any time soon.

explain to me what I don't understand. I completely take for granted that the math works, and I'm sure you have a firm grasp on the mathematics involved on a first hand level haha...

I'm not debating the true validity of whether black holes really exist or not, I'm posing an important question though as an advocate for the devil because there are two scenarios here, both with certain strengths:

1.) Black holes are real and perform as most high level astrophysicists say they do...and the laws of physics completely break down at the core of the idea

OR

2.) There is another explanation for what the observations and math are showing that we don't fully grasp that allows for physics to stay in place throughout the model that never breaks down.

I believe what astrophysicists say they think is happening here, what I find hard to swallow is that after their conclusion is drawn, they just throw there hands up in the air and say that science and physics have no answer to what lies beyond the event horizon. That seems to me that maybe, just maybe, science has gone down the wrong path.

Scenario one is likely the case in my mind, but it's not unreasonable considering the seemingly unreasonable conclusion of number 1 given everything else we know about the way the universe works would lead us to believe a total dead end like a black hole might suggest we may be making some sort of fundamental mistake.

I'm more of a history buff than a space geek, but I know a fair bit. I am just reminded of all the "don't question it, we know the sun revolves around the earth" type of zealotry that has been repeated throughout the past innumerable times, only to fall flat on it's face down the line. I'm not saying that's the case, I just think there are eerie similarities with stuff like "dark matter" and "black holes" that really completely defy logic yet everyone accepts them as good as gold.

I get lost thinking about how far away we have glimpsed into space. It is insane if you really think about it.

Thanks. I haven't posted a video in years and I can't figure it out.

Anyway, what else could there be but a black hole? This is a video of stars at the centre of the Milky Way galaxy orbiting an unseen in all spectrum a central invisible mass. They can calculate how much the mass by the velocity of the stars as they whip around this core effectively proving a supermassive black hole exists there. They don't even need special theoretical mathematics at this point; just regular Newtonian classical physics.

not good enough for some here, brah.
we need a report from those that have visited the event horizon.

No problem.

Only copy the characters after the = on the URL for youtube bids.

Black hole is the only answer we have at this point, though who knows what will be uncovered in the future. I do think it is a black hole too, but I'm just play on devil's advocate.

No, I dont understand the math of black holes. Thats why I dont make criticisms on the theory, because I dont understand it and havent studied it on an academic level. You dont understand it either, but seem to think youre qualified to make criticisms of the theory.


Its like someone who has never trained any kind of grappling watching a ufc and seeing someone get taken down and choked out, remarking that thats stupid and wouldnt work on them, they would just do x y or z. Go roll with someone who knows what theyre doing and get back to me if x y and z are legitimate ways to stop their technique.

Study astrophysics, (and no reading a few articles doesnt count) and develop the mathematical skills required to really understand the theories, then your criticisms will be taken more seriously.

a.) 9/10 topics on the forum nobody is an expert in. By your logic, let's all just leave.

b.) I have stated that I accept the math at face value, I don't believe the scientists involved to be pulling anything disingenuous in their findings. Thus, I have not criticized "black holes" or "dark matter" based on the math in and of itself.

c.) All I'm at odds with is the lack of observational data, IE, recording something entering the event horizon and disappearing completely in it's current form. This to my knowledge has never been recorded, and the images presented as "proof" of this phenomenon seem more like "likely suspects to fit the bill if the bill is correct" rather than "here is where it's happening" in a proven sense. It's a nuanced point, but the main evidence for black holes still relies almost entirely on theoretical math that is untesable, hasn't been tested or has no parallel elsewhere in science.

I can't be wrong about anything, because I'm asking questions and positing scenarios as quite possible given the current evidence at hand. I've said that the evidence points to black holes being a reality regardless of the specifics, I've also pointed out the conclusions aren't complete.

 

[random nerd]

i dont think you would witness something enter the black hole.

for instance, the shuttle would look as if it stopped right there because time would appear so slow to an observer.

everything will appear as if it is trapped at the door even though it had passed through.

a. Take an example thread-Help me drill a hole in my wall. If a guy who had been doing carpentry work for the last 30 years of his life, and was an expert in the field came in and gave instructions on what to do, most would agree and say do what that guy says. But instead its a bunch of amateurs giving their opinion on something with no clear cut expert in the field commenting, which is fine. You are the one guy with no carpentry experience disagreeing with the expert once he gives his instructions.

b. You dont understand the math. Physics is based on math. If you want to understand physics, you need to understand the math. Talking about physics isnt physics. Physics is in the math. If you dont understand the math, you dont understand the physics, and your opinion on the matter is irrelevant.

c. There is indirect observational data. You dont really understand that data. If you study it, and understand the math behind the theory, and then say this isnt enough data to more than reasonably believe theyre there, then your opinion will be taken seriously.

This is what I had heard as well.
