right but that doesn’t make sense with accelerating expansion
Correct, it's more unlikely, but we don't know much about dark energy and it's force expanding the universe so pretty much all theories are on the table.
It's just turtles all the way down
True. Maybe it’s the optimist in me but I feel like at every point in our understanding of the universe, our assumptions have been too narrow. For us to think there’s only one universe as we think of it today and it’ll blink out after 20 billion years and this was the only universe ever just doesn’t seem plausible to me
edit- I should add were obviously in a simulation anyway so why worry about it
I’m gonna see if Dr. Becky has a video on this.
So cosmic heat death is the ultimate fate of our universe … wow ….
My absolute favorite sci-fi author has a few short stories regarding the possibility of alternate universes/realities. Alastair Reynolds wrote Signal to Noise about the discovery and interactions of a few realities. The real mind-fuck one actually doesn't have a lick of sci-fi in it at all, it's called Everlasting.
I've read his entire anthology, can't recommend him enough. He does realistic sci-fi, no FTL travel.
Well, the other bombshell in that article is the reactor in dying and gives 4 less watts per year and we are shutting systems down. They say we will be fine through 2025, but after that who knows.
It’s already like 20 years past it’s design life isn’t it?
Just mind boggling how unfathomably far that thing is. And how goddamn fast it’s moving - 10.5 miles per second (38,000 mph)
And it is still not even 1 Light Day away.
something like 21 light hours away
Space flight fun fact: from Earth it is apparently easier to fling a space craft out of the solar system than it is to shoot one at the sun, because in order to fall further into the gravity well you have to kill all of your tangential velocity, as opposed to reaching an escape velocity you just have to increase it a bit.
Fun fun fact. Its actually cheaper to go away from the sun first and then drop in.
Old as hell? Check.
Deteriorating rapidly? Check.
Doesn't know which way it's pointed? Double-check.
Is it because it’s solar powered and the further it gets the less power it can draw from the tiny sun? Or is it nuclear and the fuel is reaching its half life? Crazy to think about either way
So... still functioning at 105% instead of 106%...
still kinda poopy that its been struck by a micrometeoroid before we even get one full picture.
Well damn, there goes my #FlatPluto theory
It's just incredible that we got the resolution on the high-speed fly-by sharp enough to see mountains.
Not only that, but you can see how tall they are proportionally compared to the curvature of the planet.
Only 14 years old!
*interest from libertarian astronomers intensifies*
Happened to see one of the SpaceX barges go by while waiting for my cruise to leave port. Kinda thought it would have been bigger tbh
