I found the Waterworld exoplanet fascinating because of its ambiguous state: water in plasma form??? Having some properties of both liquid and gas, overall its neither or both...All at once...Simple(?).A whole bunch of really weird planets have been found out there. Just some of them are shown in this Destiny video which has very high production values and fantastic CGI to visualise them for us. Check it out.
Yup, tell me about it. This planet has been raped and pillaged like it's an infinite resource since the start of the industrial revolution. Even to this day, companies are always talking about making more and more physical products, whether they be gadgets, cars, ships, whatever. This planet's resources are finite and one day that's gonna bit them hard. It really brings home just how futile, wasteful and cruel wars are. I'm thinking about Putin's abomination in Ukraine in particular.In a way it fills my heart with sadness, thinking about the miracles hidden in remote places here on our own planet, places like the Amazon, with its myriad of life and plant forms, so weird and wonderful: some recently discovered, already on the brink of extinction; some gone, forever unknown.
We shall never know what we have missed.
All because of the relentless exploitation of this natural marvel.
Although hypothetical, the idea of anything 'solid' existing anywhere near a BH is hard to imagine.I liked the blanets - planets born around a feeding black hole from the accretion disc. The accretion disc is extremely hot, can shine as bright as stars and the region around the black hole is a violent and tormented place, with significant time dilation near it, too. Imagine a planet existing there, only to one day to inevitably fall into the BH, probably not that far into the future. Would be amazing to study if it was possible to send probes there, but please nothing living, hell no.
That would make such a planet a near impossibility. I’ve not heard of those requirements, but maybe yeah. Thing is, if one isn’t too close to it, the gravitational force is just like a regular star.Although hypothetical, the idea of anything 'solid' existing anywhere near a BH is hard to imagine.
Scientists say that for a blanet to get close enough to the BH without disintegrating, then the BH should be enormous, something like 40 times the mass of our friendly BH in the center of our galaxy. Another requirement is that the surface of the BH should spin in something approaching the speed of light.
Not a lot to ask, really....

True, we shall probably never know what really goes inside those hell holes, unless we discover new physics, new laws, and those new laws would make quantum physics look easy-peasy.I think to uncover the deepest mysteries of black holes, we'd have to discover new physics that would let us look past the event horizon.
Did you know that time and space swap places inside it? No, I don't get it either, but that's apparently what happens.
Do you have a link for that article? Sounds interesting and says stuff I didn't know about black holes.
Indeed, I think we're gonna have to wait a while to look inside one of those. Did you know that the earth compressed enough to form a black hole would have an event horizon with a diameter of around 3cm?True, we shall probably never know what really goes inside those hell holes, unless we discover new physics, new laws, and those new laws would make quantum physics look easy-peasy.
No, I was not aware of the time/space swap, I wouldn't get it anyway.
Here is the link, the info included in my post are in paragraphs 4 and 5.
...blanet... that word is annoying.Indeed, I think we're gonna have to wait a while to look inside one of those. Did you know that the earth compressed enough to form a black hole would have an event horizon with a diameter of around 3cm?
Note that such an extreme scenario for a
pblanet* with it orbiting so close and the extreme spin of the BH is for life to hypothetically form on it (please, no). Other articles I've read talk about blanets forming in that hellish region of the superheated accretion disc and there was no talk of life evolving on there.
*Is it just me, or is that word annoying?
Ya, it wuz awiens! 😁Life Science- Doorway seen on Mars
Interesting picture taken on Mars. Looks like a perfectly carved doorway to me.
Ya, it wuz awiens! 😁
Anyone home? ‘Doorway’ on Mars spawns alien conspiracy theoriesAt first glance, it looks as if a doorway has been carefully carved into a rock face on Mars.uk.news.yahoo.com
