Hubble is actually the same altitude as Starlink, 340 mi. There have been proposals to boost Hubble to higher altitude so it doesn't reenter next decade.
But since Hubble doesn't look towards the Earth, it won't see as many as from Earth.
It is why the Google IPv6 stats fluctuate between weekends/holidays and weekdays. IPv6 is much more prevalent on home and mobile networks so increase on non-work dyas. Companies have IPv4 networks that they don't want to upgrade. We have dichotomy where 50% of clients have IPv6, but most of the small sites do not.
The other thing I have seen is that engineers make things complicated. Normal person has IPv6 enabled by default or enables it in router, and it just works and they never notice. Engineers want to configure things manually, but IPv6 is hard if fight against the dynamic defaults.
My theory is that many people don’t have space for speakers. Soundbar sounds better than TV speakers.
I also think the focus on surround means people don’t consider stereo speakers. Good bookshelf speakers are better than surround kits and easier to install. I also wonder if normal speakers are no longer cool.
Finally, I wonder if people don’t like the big receivers. There are small amplifiers but I can’t find one that works in home theater with HDMI port.
LE Audio should fix the quality and latency problems. The latency is significantly lower and the bandwidth is twice Classic Bluetooth. There are new default codecs that are better, and there should be enough bandwidth for lossless. The other nice thing is enough bandwidth for bidirectional streams instead of low quality audio when use microphone.
The current problem is that LE Audio implementations are new with lots of headphones having them as beta.
The Navy also needs the Constellation class frigate. The proposed replacement based on the Legend class cutter. It is basically a corvette like LCS on a bigger hull. The Navy doesn't need more corvette, they need proper warships.
Red Sea shows that ships need more defenses now that anyone can build anti-ship missiles and drones. Maybe they should have called Constellation light destroyer and DDG(X) a cruiser.
What the Red Sea has shown is that drone and anti-ship missiles are massively overhyped. A 40 year old ship design has fended off hundreds of such attacks without losing a single ship. Without even taking a single hit.
> The Navy also needs the Constellation class frigate.
The Navy needs ships it can actually build, the Constellation is trapped in an unending design hell and is already years behind.
There is distinction between seeing when events happened, and when they really happened. The latter can be reconstructed by an observer.
In special relativity, time is relative and when things actually happened can be different in different frames. Casually linked events are always really in the same order. But disconnected events can be seen in different orders depending on speed of observer.
> But disconnected events can be seen in different orders depending on speed of observer.
What are "disconnected events"? In a subtle but still real sense, are not all events causally linked? e.g. gravitationally, magnetically, subatomically or quantumly?
I can understand that our simple minds and computational abilities lead us to consider events "far away" from each other as "disconnected" for practical reasons. But are they really not causally connected in a subtle way?
There are pieces of space time that are clearly, obviously causally connected to each other. And there are far away regions of the universe that are, practically speaking, causally disconnected from things "around here". But wouldn't these causally disjoint regions overlap with each other, stringing together a chain of causality from anywhere to anywhere?
Or is there a complete vacuum of insulation between some truly disconnected events that don't overlap with any other observational light cone or frame of reference at all?
We now know that gravity moves at the speed of light. Imagie that you aretwo supernovas that for some unknown reason, explode at essentially the same time. Just before you die from radiation exposure, you will see the light pulse from each supernova before each supernova can 'see' the gravitational disruption caused by the other. Maybe a gravity wave can push a chain reaction on the verge of happening into either a) happening or b) being delayed for a brief time, but the second explosion happened before the pulse from the first could have arrived. So you're pretty sure they aren't causally linked.
However if they were both triggered by a binary black hole merger, then they're dependent events but not on each other.
But I think the general discussion is more of a 'Han shot first' sort. One intelligent system reacting to an action of another intelligent system, and not being able to discern as a person from a different reference frame as to who started it and who reacted. So I suppose when we have relativistic duels we will have to preserve the role of the 'second' as a witness to the events. Or we will have to just shrug and find something else to worry about.
Causality moves at the speed of light. Events that are farther apart are called spacelike and aren't causally connected.
I think you might be confusing events that have some history between them, and those are influence each other. Like say right now, Martian rover sends message to Earth and Earth sends message to them, those aren't causally connected cause don't know about the other message until light speed delay has passed.
We still haven’t proven whether some quantum effects do or don’t follow this. So there may be a loophole where information can move faster than light but the carrier for that information can not. Which might make ansibles possible some day, with the caveat that you can only have so many conversations per ansible before you need a refill with new entangled matter. In which case you have to divide the information by the travel time to determine your aggregate data rate. And the travel time will be at a fraction of the speed of light.
So you might be able to consult on which planet to terraform but you’re not going to video call the wife and kids unless you’re the richest person in the galaxy.
> But wouldn't these causally disjoint regions overlap with each other
Yes.
> stringing together a chain of causality from anywhere to anywhere?
No? Causality reaching one edge of a sphere doesn't mean it instantaneously teleports to every point in that same sphere. This isn't a transitive relationship.
> What are "disconnected events"?
The sentence you're responding to seems like a decent definition. Disconnected events are events which might be observed in either order depending on the position of an observer.
One thing is that you need to tell the insulin pump when you eat food so it can deliver insulin to cover the food. I bet that is a lot easier in an app than some separate controller device.
Insulin pumps are paired with glucose monitor. I bet it is handy to check glucose levels to make things are stable and correct if off.
