New Scientific Discoveries, Part Drei

As you were all aware voyager one and voyager two are both beyond the Heliopause and out of our solar system. They are both reporting something very interesting now. The farther they get from the effectS of the sun the greater the density of charged particles per cubic centimeter of space has been:

https://www.google.com/amp/s/www.sciencealert.com/for-some-reason-the-density-of-space-is-higher-just-outside-the-solar-system/amp
 

that seems counterintuitive to me. That there would be a greater amount of charged particles outside of the flu each of the sun then inside of it

Didn't read that yet but would not it be because outside of sun gravity there is nothing pulling them in so that might explain why are there more 'free' particles? (I know there should probably be some micro gravity of the system anyway but maybe mass of free particles is pullgin them togather). Now lets see how big dum-dum I am....

I'm the enemy, 'cause I like to think, I like to read. I'm into freedom of speech, and freedom of choice. I'm the kinda guy that likes to sit in a greasy spoon and wonder, "Gee, should I have the T-bone steak or the jumbo rack of barbecue ribs with the side-order of gravy fries?" I want high cholesterol! I wanna eat bacon, and butter, and buckets of cheese, okay?! I wanna smoke a Cuban cigar the size of Cincinnati in the non-smoking section! I wanna run naked through the street, with green Jell-O all over my body, reading Playboy magazine. Why? Because I suddenly may feel the need to, okay, pal? I've SEEN the future. Do you know what it is? It's a 47-year-old virgin sitting around in his beige pajamas, drinking a banana-broccoli shake, singing "I'm an Oscar Meyer Wiene"

The thing about it that piques  my curiosity Is that these particles have mass. Not a lot obviously but cumulatively over time will they cause a vehicle traveling in interstellar space like voyager to decelerate? Theoretically if you could accelerate to 50% of lightspeed and head towards Proxima Centauri would you still be going 50% of light speed when the time came to begin deceleration?

curious, the author o' the article didn't listen to albert.

gravity don't "pull" or "force." need change your pov if you are gonna understand general relativity. earth is not pulling you down, but rather is rushing up towards you. is why you feel (and are) weightless if you, for example, jump off the roof o' a multi-storied building. 

*shrug*

is extreme difficult to change pov if even the science writers is explaining using newtonian nomenclature.

HA! Good Fun!

Exactly. Everything wants to follow a geodesic (a straight line in curved space) and Earth is pulling your geodesic inside it. I think this is the best explanation I've seen so far:

50% of light speed is alot. So it might not reduce too much, but it would certainly happen. Specially if you consider collisions in the way there. Even a small fragment would hit the ship as a bullet or worse.

I knew the two Voyagers had left our solar system. But this new discovery is very interesting to me. Thanks for posting.

video

this is a fantastic video. we use a jumping off a building scenario all the time when am attempting to explain and am knowing based on the glassy-eyed stares we get in response, am rare making an impact. figured if it were good enough for albert einstein...

thanks for the vid as we will unapologetic be using in the future. 

HA! Good Fun!

Sadly had some issues, so we probably won't see the 15km hop soon.
