Scientists have found evidence for a new, ninth planet in our solar system with a mass around ten times that of Earth. Get hype.

Unless they were directly opposed, they'd collide or fling eachother into funny orbits eventually. Though smaller planets further out would take longer.
There's a reason planets tend to fall into an orbital resonance.

I'm a layperson scurrying across the floor of /sagan/, please don't annihilate me.

Is there any reason white holes would exist? From what I understand black holes just keep growing, gaining in mass and gravity magnitude in relation to their mass. Their ultra-compact density is what gives them their swag about the vacuum of space.

If white holes were real, then how would black holes continue to grow and increase their gravity? Debris, planets, stars and other space stuff 'slows' as it reaches the center of the hole as I understand it. Would that mean filling a water balloon with a tiny leak in it is a good analogy for what's theoretically happening?

Overly simplified version: Einstine's math allows for the opposite side of gravity, repellent gravity. Instead of pushing down on the fabric of space time and making a 'dent' it is pushing up and making a 'hill', kinda. Just like the gravity of a blackhole is strong enough to keep light from escaping, the gravity of a whitehole is repellent enough that light cannot breach it.

What if White Holes only exist for a fraction of a second and in the wake of their brief existence form entire universes in a multiverse.

tl;dr the Big Bang was, in fact, a White Hole and we are all (entropy, spacetime) that endlessly falling 'hill' (as opposed to a black hole's infinite depth) that will eventually tear and fizzle.

This old ass thread was very insightful. Time for another bowl.

There will always be shit to fix on Earth, that can't stop us from going outwards. We've got the resources to spare.

We'll definately see atleast a man on Mars, probably the start of a colony too (never bet against Elon). Maybe a base on the moon, but my bet is that a race to Mars will be kicking off soon and the moon will be a sideshow, R&D for Mars colony tops.

Maaaaaaaaybe Skylon, not holding my breath on that one though. Ion propulsion should get much better and if we get fusion knocked down in a decade or 2 that could feasibly take us to a nifty fraction of C. Alcuibierre drive seems like a pipedream, but you never know, would require something like a fucking anti-matter power source probably, though perhaps a large enough fusion reactor would do too...

If Elon gets his MCT concept with the BFRs done & produced, space mining probably will be feasible then. 100 tons to Mars yo, could probably haul serious cargo from the asteroid belt too since it wouldn't have to fight the gravity well of Mars.

AI most likely too, don't know if superintelligent AI, depends on how fast the AGI takes off, though looking at machine & deep learning these days it'll probably take off like a rocket.

Humanity's technology is on an exponential rise, just think how much the world changed between 2005-2015 compared to 1995-2005. We probably can't even imagine the shit that will be around in 60 years.

A huge rock is headed straight for earth

We wrap a tarp around it with a space craft
Fill the tarp with a heavy gas
Once the pressure is high enough inside the tarp
We turn on rockets compressing the gass as much as possable on one side of the tarp
Then we blow up a nuke
Changing the course of the rock enough not to kill everyone on earth

What does /sagan/ think of this?
I think it's a pretty fucking sweet idea. I wonder what sort of materials you could use that are both light weight and durable enough for a floating Venusian colony. I had an idea that could help with the buoyancy of the thing: non essential parts of the structure (floors and walls) could be made out of brick like objects that are either vacuum hollow or filled with a gas like helium at very low pressure. They would be brick like objects because many could be punctured without jepordizing the integrity of the station. one could also vent waste heat out the bottom and sides to create a bit of thrust.
The only major problem would be in getting people and materials to and from the colony. Then again, I suspect by the time we're in a position to build something like this, navigating the haze of the Venusian atmosphere safely won't be much of a challenge.

Humans go places and do things to get stuff. Not just to do it, those emotions are just used to motivate people. Every great explorer was after land, gold, slaves, riches. I want riches. The asteroid belt is where its at.

I wouldn't want to go to Venus, there isn't anything there. You can't land on the surface, no moons, no nothing, bbbbooring. Even in your super-future there will be shit-holes no one will want to go to. Look at the US state of North Dakota, a giant frozen field full of self-destructive Native Americans, up until the last 10 year or so, it was fucking empty because all that was there was grass and nothing. But then fracking happened and then there was an oil boom and then 100,000s of people looking to get rich, and most of those people are blue collar folks with nothing else going for them. The blue collars go loose limbs getting the riches to pipe back to cities to be profits for rich owner of industry.

This is exaclty happening now, SpaceX, ULA, Virgin Galactic.

Given our lives now, i know in 300 years there will be a miserable dick job of 'asteroid miner'. So you didn't go to college and you are a physically capable young person, get your ass to space and go get some stuff.

I'm not folding my arms, I like realistic sci-fi. In your universe, I want magic powers like the force and shit.

>The asteroid belt is where its at.
Well obviously colonization of Mars and Venus and the construction of space habitats would take place within the context of a well established and rapidly expanding space economy. I don't have to tell you that there is an incredible abundance of resources between Mercury and suburban Jupiter. In the midst of taking advantage of this tremendous windfall, it only makes sense to put habitable places where we can. If for no other reason than as a way station and a refuge. (think a stop for fuel or something at a space station orbiting Venus on your way from Earth to Mercury or something)

>I wouldn't want to go to Venus, there isn't anything there. You can't land on the surface, no moons, no nothing, bbbbooring
The most brutal hellscape in the solar system is boring to you? I don't want to insult you or anything, but whaaa? I don't know how any place in our solar system could be considered boring (well, aside from the MASSIVE expanses of literally nothing, but that goes without saying)
>you can't land on the surface
With currently existing caveman tech it's not a very good idea.

>Given our lives now, i know in 300 years there will be a miserable dick job of 'asteroid miner'. So you didn't go to college and you are a physically capable young person, get your ass to space and go get some stuff.
Frankly neither of us can imagine what human societies will look like in three centuries. If neo-liberal capitalism is still the default system, I'm not sure we'll even be around in three hundred years. Anyway, asteroid mining will likely be almost entirely automated. It makes more sense to have a bunch of durable, easy to produce machines hacking up rocks in space, not a bunch of frail bloodsacks who can't function in an irradiated, freezing, vacuum.

> I like realistic sci-fi
Me too. I love Star Wars, but the lore of franchises like Star Trek and Mass Effect is so much more interesting BECAUSE so much of it is plausible.

So I was playing around on SpaceEngine on my very mediocre PC and came across this view which I thought looked pretty cool so I screenshotted it (the image on the left). A day or so later I was watching SpaceEngine videos on YouTube and came across a video with the image on the right on it. I looked for the coordinates on the video but there was nothing there.

What are the chances of this? I couldn't believe it when I saw it, it's undeniably the same view, the chances of this are miniscule right? Am I the only one absolutely amazed by this?

so...
if you want to collapse the core your gonna need some VERY STRONG magnets, drills, charges (controlled as fuck as the crust isnt purely solid it has fractures & holes & allsorts which kill miners e.c.t).

First, well need to friends up or kill & impersonate someone "high up", with funds we can become a private interest in the many 'space programmes'. With the severe lack of funding NASA are recieving, they are playing ball to a lot more private interests & with their brains & techonology the charges could easily be places in the least dangerous palces meaning you dont die & can continue your mission).

To bore holes we will have to become frackers, we may need to relocate. The best places would either be the oil fields in asia as that has less crust & population to traverse or the American lands which are heavily fractured & drilled. If we impersonate or friends up the right people we will have access to underground networks, which go deeper than people think & are surprisingly stable. But once we have the licences for that, we will need similar minds to employ who hate things enough not to grass us up for depleting the polarity of the earth & reduction on key natural phases & fields.

With the resources we now currently own, not only do we not have to bury down ourselves, we can send people who hate things more than us & dgaf more than us. Reward their families amply if they get fucked up. That & we have a secure network of illegal activities intent on felling the clouds & allowing our precious shields to wander off into the vacuums of space.

Now you finally have the means to affect the polarity of the earth, you will need to connect the global power network, which there isnt yet. You would have to make one, but with our resources so far this will only take half a life time or so. Dw if you die or me there are plenty of other cunts we can trust. Now with the power, we can safely construct magnets at the entrance to the large bore holes & lower them near the crust before activating. Cables would need to be adamantium alloy as that stands up to even super heroes according to tv & comics so its pretty tough shit.

Now all which remains is for our calculation wizzes to be correct, the hardware not to fault (well have to employ asians & pay them well as were lazy & require cyanide). You now have, as I currently see it, 3 choices... which will be more effective I have not enough time to consider, like ever in my life.... You I recommend you take a shot & flip a coin, yelling fuck yeah.

A: Start both magnets at the same time in the hope this freezes the movement of molten materials & any magnetic materials will hopefully travel to the magnets, disrupting the orbital flow of the plasma & other materials. This could do nothing & just fuck every electronic ever up & stick us all to the ground via our belt buckles/tear things out of people bodies who have pins or heart tickers e.c.t

A field force propagates at the speed of light forever. Suppose this field force causes a quantum reaction when it encounters certain particles. This reaction releases a gamma ray burst in all directions.

Now suppose an observer is sitting in the direction perpendicular to the asymptote of the gamma producing event. {pardon the unwieldiness here is a visual representation: )-> }

Does he notice an increment between detecting the gamma ray, and detecting the field force? Or does he experience it all at once, as an event horizon?
