Are these the same cats we rely on for runaway asteroid warnings?
Surprised scientists are a concern. That's why I never threw a surprise birthday party for one.
Hyperbole. The super-massive blackhole in the center of our galaxy is 4 million times the mass of our Sun. 70 times the mass of our Sun isn't all that big. It's a mini-me of Sag A*
I get what they are saying; that to find one that size floating around in the galaxy is much more strange, but to say it shouldn't exist is a bunch of bull****.
LIGO is a relatively new project and it's already recorded many black-hole mergers. ((2) black-holes of 35 solar masses merge into a single 70 solar mass black-hole?!?? Definitely not impossible!) Just our solar system alone is about 4.6 billion years old (our galaxy is far far older (probably closer to 10+ billion) and black holes have been around far far longer than our solar system. Not only that, our Sun is likely a second generation star (or possibly a 3rd generation star. That means that one or two previous stars went supernova before our star was even born out of their left-over material.
The question isn't, is that even possible. The question is, how often does that happen over a period of 14 billion years of the known universe? I wouldn't doubt for a second that there are multiple massive (near or above 70 solar masses) black-holes near the center of our galaxy.
I don't understand this. Sagittarius A* (The black hole at the center of our Milky Way galaxy) is supposedly 4 million times the mass of the sun, yet this article is saying they're stunned to find a black hole 70 times the sun's mass?
As usual, you're way ahead of me!
Black holes don't exist.
Fire breathing dragons don't exist.
Unicorns don't exist.
And there is no god of thunder.
Mankind's imagination. Don't get sucked in.
Kidding about the black holes, and pun intended, right?
The pun was intentional. But no I do not believe in black holes. I do not believe in the big bang theory either.
Okay. You realize they took pictures of two black holes earlier this year, one of them being the one at the center of our galaxy?
There are scientists who don't believe in blackholes. The pictures are just multiple gravitational fields effecting dust at a central location. If you remove Saturn out of the center of its rings they'd swear that was a black hole too.
So I'm not the only one.
If you removed Saturn, the rings would float off into space.
The theory you're talking about makes no sense. Gravity is caused by mass. There's no such thing as "gravitational fields" with no object creating the gravity.
I should have started a new paragraph when I said if you remove Saturn from its rings to make that a lot clearer.
You cannot have a gravitational field with no object creating the gravity is exactly why some don't believe in black holes.
The bowling ball on a trampoline is a topographical look of objects creating gravity within our galaxy. But the scientists who believe in black holes want you to believe that there is a bowling ball imprint without the bowling ball. There's gravity but no object, so the believers say the object is a singularity.
Well the distance between galaxies is expanding. (meaning our whole entire galaxy is on wheels) But your singularity, if it really was a singularity, would not be able to move with the galaxy. Your singularly would be a pothole within the galaxy instead of being part of the galaxy. It would sit in one spot and swallow anything that comes it's way including planets, stars and asteroids. etc.
So the believers want you to believe a black hole is a singularity that moves with the galaxy. The naysayers say that's impossible.
A bowling ball imprint without the bowling ball that moves with the galaxy. Yeah, I'm never going to believe that. And that's why I tell people opinions vary just like beliefs.
To each his own.
Black hole is just what it's called. It's actually an incredibly dense sphere, like a neutron star on steroids. Any theoretical singularity (which goes against physics as we understand it) would be at the center of the black hole, though most scientists don't believe singularities exist, which is one of the reasons they're trying to use string theory create a unifying theory between Einstein's Relativity and Quantum Mechanics.
O.K. I've changed my mind.
I just figured out a way to explain it to myself. Which is very important to me. Because if I can't explain things to myself in layman's term I tend to struggle believing them. So hopefully my self created explanation helps others to understand.
So a star blows up leaving behind this invisible electromagnetic sphere of pure energy. ( radio waves and gravity are invisible) Due to the fact this thing is electromagnetic when light hits it, it doesn't bounce off of it because its actually feeding it. It absorbs the light and continues to grow. But the outer edges of this electromagnetic sphere, much like the super heated portion of Earth's atmosphere, still interacts with dust particles. Super heating the dust particles. And these super heated particles can become visible even though the sphere isn't.
So as this sphere grows in size it is actually making the galaxy expand. And that's the part that got me. I told myself that if this thing is real then the Milky Way Galaxy should be expanding. I googled, is the Milky Way expanding and sure enough, it is.
So it's not a wormhole in space or a singularity. (like the movies would have you to believe) It's just the radio waves and an electromagnetic remnants of a star. It takes that radiation time to dissipate. But it can't actually dissipate because its constantly being feed by light and the radiation from other stars. A highly dense radioactive bubble. That's what a black hole is to me and I'm sticking to it.
I really didn't know the Milky Way Galaxy was expanding though.
So what do you think Runwild agree or disagree?
I'm sorry, but no, I don't agree. A black hole is a solid object...the most solid object in the universe, in fact. The reason you can't actually see them is that they're so dense that the gravity they create is too strong for even light to escape.
Einstein mathematically predicted their existence before anyone had any inkling of their existence. Even Einstein thought he made an mistake at the time. This was before anyone really even though about what crushing that much mass into a small space would have actually meant gravitationally. Remember, each amount of mass has gravity. The Earth's gravitational pull is spread out over 7,500 miles in diameter and 25,000 miles in circumference. That means, while all the gravity is having an effect on you. A large portion of it has less of an effect on you. (the mass on the far side of the Earth.
Gravity weakens as distance grows between two objects. Now, imagine the Earth was squished into the size of a marble (half an inch in diameter) and that marble was 2" away from you. (yet, still contained all the Earth's mass and gravity, but now all of it's mass and gravity is within 2" of you!) You would go from weighting 150-250lbs on full size Earth, to some ridiculous amount that your soft liquid filled body would likely crush into a a gooey like liquid state and then crushed even more into a solid evenly spread out over the entire surface of the marble size Earth. (the same way planets become spherical one they reach a certain mass due to gravitational forces)
Also to to note. Any scientist who can't do math, isn't a real scientist. More likely they are just people being paid to produce an opinion that supports conspiracy theorist and / or capitalist agenda. (ie, they were paid to write a bull**** paper or an ulterior motive) The energy and auto industries has been doing this for years.
Very dramatic narration! I was expecting you to post the final chapter, where they actually took the pictures of Sag A*.
