All of the "space junk" is going to form a serious barrier to us colonizing the far reaches of spac...
I can't say it with a straight face. We ain't colonizing sh*t. We all know it. Science knows it, Common sense knows it. We're stuck here, so you'd better get used to the idea.
Black holes were always fascinating to me but it was always pretty obvious that we really didn't know much about them - and there were these weirdly juxtaposed descriptions of them as either collapsed stars that retained a small amount of matter surrounded by an intense gravity well like field
OR -
Wormholes connecting different dimensions
Didn't Tesla get credited with discovering pulsars? He was picking up & monitoring the regular intervals of radio signals (?) and initially believed it was another intelligent civilization I think --- but --- it wasn't or course
I could never comprehend all the simultaneous movements of planetary rotation, revolution combined with solar system level movement & in the galaxy also moving along as well?
Seems like we would hit a lot more stuff -
Also - entirely fascinated with what happens to the human body when exposed to various degrees of exposure to the vacuum just outside your spacecraft -- you explode? While also freezing? Or IMPLODE ? While your blood boils?
Unless you're facing the sun then you may also get burned ?
But - what it theres just a SMALL leak?
Does your craft implode like a breached submarine at depth?
Or do you just notice a draft - and start having breathing problems?
Anyone remember the 80e movie "Outlander" with Sean Connery?
They had several scenes with death by exposure to space - it seemed slower than I thought it would be
Also -always thought NASA should start a trash / waste disposal program where we just load up landfills and other earth waste into large launch vehicles and shoot that crap in the general direction of the sun!
Or the other direction, whatever
Something tells me if we were taken into the voids outside our upper atmosphere - and could just suspend and look into the incompressible emptiness -- it would be a kind of HP Lovecraft type horror
PS - favorite planet was always Saturn with a soft spot for Neptune
PSS - I believe Saturn changed colors at one point (gold-silver?) and no one knew why or how
PSSS - Aren't there reliable data showing how Saturn emits unique radiation/frequencies that filter through "the rings" - and hit the earth with some measurable effect?
And other assorted high weirdness - its a mind trip for sure
The recorded sounds of radio (etc) signals emitted by the sun + planets - is somehow the most terrifying thing ive ever heard - especially Jupiter
DuckDuckGo that mess, cadets -
Its alien and unsettling, man
