This means it’s an asteroid with a weight-class that would have burned up in Earth’s atmosphere, if its orbit happened to intersect ours more directly.
A quick search suggests that something as small as 5 meters can survive hitting the ground, however there are a number of calculations to consider including the speed it is traveling, the entry angle, and the material it is made of.
I didn’t plan to view the eclipse over Potato World, but arriving at the hotel and discovering that it was next door did seem like a sign from the universe.
Me too! Always wanted to get into, thinking it worthwhile to have a running solar system or celestial model on your own machine that you know how to operate etc. Just never really tried sadly!
Oh yea I’ve used it and from memory it’s awesome as you say. I was more talking about getting into the technical details of running a model and calculating various things of personal interest.
If it's not seen as much, that probably means the green material is heavier than iron. It's less common, but large enough stars can fuse even heavier elements. That's where all those elements on Earth came from in the first place.
That is fascinating, I want to know, is there any way to prevent this during assembly? Even with extreme clean room protocols! Does it happen with other telescopes?! Down the rabbit hole, I must go.
So, there’s nothing in universe that is longer than “soon”. This prediction of going nova this year, only means it already happened but you can’t see it yet. And since it’s going super nova, that means entire even will be boring anyway. You’ll see a white dot that will increase in intensity during this year and then fade away equally slowly.
For people wondering about dates, there are none. Just like Beetlejuice is expected to explode soon™, that actually means 3000-10000+ years of waiting. So don’t get your hopes up. Out lives are but a blink in universe. All you can do is be diligent and watch it constantly. Doesn’t mean you’ll see much either since at peak magnitude of 2.5 it will be dim enough that you’ll need telescope to see it.
Nova, not supernova. Novas happen multiple times. Supernova do not but it doesn’t say supernova. Soon, as in within the next 6 months since its following a cycle that happened about 80 and 160 years ago.
Visible with unaided eyes for several days (but still dimmer than about 120 stars in the sky), and with binoculars for about a week, according to NASA.
I always thought of our universes as just a bubble, with dark matter all around us. It’s not the edge of the existence as much as the edge of our bubble.
We might not be the only bubble, but it’s impossible to interact or even observe them. Could be millions, could just be us. No way to every know.
Our bubble keeps expanding, until the edges aren’t dense enough to displace whatever’s out there. And we’ll either slowly fade and future civilizations will assume the universe has always shrunk. Because that’s all they’ve ever seen. Like if the human lifespan was a single minute, people would freak out everytime it approaches dawn or dusk. Not understanding that it’s a cycle.
