Share with your friends! 32 32 points Martin Kamenov Georgiev Let me get this straight…. the Voyager I probe is about 1/20 the size of the Sun and Pluto looks like 10 times the size of the Sun. Huh? No Name I think that represents Pluto’s orbit. Martin Kamenov Georgiev Okay, let’s say that it is. Then why does Voyager have an orbit? The man that did that thing It’s demonstrating how far Voyager, the furthest man made object from earth, has made it. I thought it was pretty interesting to see the scale. Martin Kamenov Georgiev ….has made it relative to what? Would it make more sense to put the Earth dot on the rim of the black hole and then put the Voyager I dot somewhere, so we can visualise it? Bottom line is, this is an historic event and kudos for the lady who helped make it happen. The man that did that thing Has made it from the centre of the solar system? And by extension the distance relative to a specific supermassive black hole’s visible accretion disc. The pluto orbit shows the outer most ‘planetary’ orbit (I know, I know), so gives a visual bounds for the size of the planetary solar system, and Voyager shows just how far we’ve managed to send a probe in 40 years of effort. If he were to put earth in the image, it would be very close to the sun. Maybe he thought it wasn’t necessary to get across the things he was trying to get across. Martin Kamenov Georgiev In other words, Pluto’s orbit is a circle and by comparing the size of it, to the size of the black hole halo, you confirm that it’s much tinier. Whereas Voyager’s dot is just…there. Do I get impressed that it’s so far from Pluto and the sun? Face it, I’m like a vaccinated kid during the outbreak of measles hanging around in an art gallery: I don’t get the picture. The man that did that thing I think it’s to illustrate that the black hole is so huge (and to demonstrate the scale of the image we’ve been presented with), because in all our history we’ve only managed to get far enough out of our solar system that the equivalent distance from the black hole wouldn’t even be enough to escape its gravity well. In other words, the scale of the black hole is supposed to be awe inspiring, rather than ‘look how far we’ve managed to get, woohoo us!’. There’s a lot of implications in that picture, but I don’t think any of them are supposed to be self-aggrandising on behalf of the human race. Ara Raven Basically, this black hole is not just bigger than our entire solar system, it is also almost bigger than the bounds of what humanity has ever physically probed in the entirety of our history as a species. This black hole is THAT big. And it’s not even the biggest thing out there. Martin Kamenov Georgiev I can just feel the yo ‘mama jokes pouring in 😀 Pickles Very cool… so the black hole is sucking mass and light from further than double our solar systems size! damn! Wonder why there is a halo of light after that though? Need to research this now Das Puggy FAKE NEWS! Everyone knows the Earth is the center of the universe, G-d has said so!
