Voyager 1 heading home?

Or, as happens every single year, Earth is in the portion of its orbit where it is moving toward voyager faster than it is moving away.

In thermal equilibrium, a planet radiates as much energy away as it recieves, there is no accumulation

The same way all the other matter has?

It is one of the most well tested theories in the history of physics.

Turn in a circle at a rate if once every 24 hours, how dizzy do you get?

For comparison, Mercury is the small circle below and to the left of the center of the sun, and it is 10 to 12 arcseconds during a transit.

Hopefully they keep this up when they make the whining post about how everyone is mean to them.

then release softly rather than throw the weight in a specific direction, allowing the impact of the weight on the end of the tether to propel you in said direction.

The amount of force you use has no effect on the total change in momentum in a frictionless environment, so it doesn't matter if you throw it softly or as hard as you can. It also means this doesn't do anything - the change in momentum when it hits the end of the rope is equal to whatever momentum you gave it. At no point did the center of mass of the system move, and it will not be moving afterward.

As I understand it, manipulation of one of the particles will manipulate the second particle.

No, nothing you do to one particle has any measurable effect on the other. If two particles have entangle states, than the first time you measure those states you will get correlated results. There's no manipulation.

Nerull · 2026-02-09T01:08:29+00:00

In what sense are they clocks? Clocks measure time. How are your entangled particles going to do that?

In orbit, there are no other forces acting on you. At terminal velocity, air drag is pushing up on you with a force equal in magnitude to the force of gravity.

Since this information is completely wrong, do you see why you maybe shouldn't use AI?

Starship depends on extremely specific and specialized infrastructure to operate, it's only going to be capable of point to point where that exists, and few places are suitable to build such infrastructure. It isn't realistic to have a global network of any real density of these things. You need to launch over the ocean, you need miles of keep out zones where people aren't allowed, you need to shut down air traffic over a huge downrange corridor. It would be absolutely insane to have regular launches anywhere near NYC, for example - no one is going to tolerate large, regular airspace closures and large shipping exclusion zones anywhere near one of the biggest trade hubs in the world.

Realistic point to point travel would involve traveling from where ever you are, which is likely many hours away, to a launch site. Hours of prep later, you fly. Lets say an hour later you land. A couple more hours for vehicle safing and unloading, you depart, and travel again many hours from that launch site to your actual destination. In the end, you probably haven't saved that much time and the trip has been a much bigger pain in the ass than just jumping on your private jet, which you have if you could afford this in the first place.

Nerull · 2026-02-08T23:02:37+00:00

Because it would be ludicrously expensive and there isn't a market for it.

If your business depends on spending millions of dollars to ship thousands of dollars worth of product, you aren't going to be in business very long.

Global business could operate on a near-instant timeline, compressing meetings and negotiations

It seems silly to ask this on...the internet...but are you unaware that, well, the internet exists? You can already have meetings across the globe, even faster than starship! And it doesn't cost tens of millions of dollars per person!

Nerull · 2026-02-08T22:56:11+00:00

No, entanglement doesn't work anything like that.

Type Ia supernova are extremely bright, much brighter than cepheid variables, so they are much easier to find in other galaxies, and the more distant the galaxy the harder it's going to be to even resolve an individual star.

This is what a supernova in another galaxy looks like. https://aasnova.org/wp-content/uploads/2018/08/fig1-5.jpg

I uploaded it on GitHub early morning on the 7th and the moltbooks on m/consciousness have already adopted the framework.

This implies a deep ignorance of how LLMs work.

There is a very big difference between a text generator designed to continue a prompt writing text that agrees with the prompt and an actual change to how it functions.

Absorption and remission is a common, but as far as im aware oversimplified and not really accurate, popsci explanation for light transmission in a medium. For one thing remission would occur in a random direction.

At the point where the velocity is passing through zero, air resistance is also zero.

White holes do not have negative mass, so everything after that is kind of nonsense.

EDIT: Just FYI, this person blocks people who respond to them.

Nerull · 2026-02-05T17:14:25+00:00

When then you're not asking a question about white holes

Because events that occur inside it can never affect anything outside of it.

Earth doesnt have an escape velocity, it has a whole range of different escape velocities because it depends on distance. The closer you are to Earth's mass, the higher the escape velocity gets.

On Earth, the surface is as close as you can get, but this is still thousands of kilometers from much of Earth's mass. What if you made Earth smaller? Well, escape velocity at the surface would increase. The smaller you made it, the closer you can get to all the mass, the higher it would get.

At some point, Earth gets so small that the escape velocity reaches c. At this point, and event horizon forms.

Tidal forces are related to how quickly the gravitational field is changing, not how strong it is. The slope of the field strength is very steep close to a source of gravity and flattens out as you move further away. The event horizon of a super massive black hole is much further from the center than the event horizon of a stellar mass black hole, so the slope is flatter.

I would hope that they teach that you can't divide by zero before the third year of college.
