Magnets how do they work?

Could you imagine being in the chuck yeiger generation of pushing the tin through the light barrier fuck that'd be so amazing I wonder how long that's going to take.

There is a cool subplot in the expance of some dude who is like, trying to break the speed record or something.

I never read the books so idk if there is more about it in them.

Spacex/Nasa have been doing some really great work. Getting into space in a re-usable form that is affordable is a massive part of the beginning process.

The way they get rockets to re-land is what some compare to dropping a pencil off the empire state building and landing the eraser on a stamp.

I'm just curious, given enough time, that flashlight will accelerate near the speed of light? If said flashlight remained on.

Anyway we should totally build a lazer, or lenses to focus solar energy in space and try to accelerate some small tiny sensor with a radio to relativistic speeds. Maybe we could sling it on a 24 year mission around our nearest neighbor if we can keep it from escaping?

Now I have an itch to find out what velocity and trajectory will work for a flyby. And how long that'd take without too much deceleration.

@baler I really enjoyed scrolling through that wiki. To think I could live another 40 years... that'd place me squarely in 2060. Still hope we get to mars.

@Jibartik I am going to try watching the expanse. Does it mostly take place only in our solar system?

4 episodes in and it's great, but a little hard to follow. I think he's a cop(in space) and the other guys are much more interesting!

If we are at the middle or falling into the middle of a black hole looking up and out? It would explain why time moves faster the closer to the center then the outside? And explain some of the relativistic effects we experience?

Light travels at a constant throughout the universe, but the universe appears to be expanding faster and faster, so the stuff farther away is disappearing from our sight? Time is slower the further we look, so its further back in time in relation to now? So like like it literally being pulled away from us faster than it can reach us. We try to explain this with darkmatter, and energy because our galaxies shouldn't maintain cohesion, yet the very structure of the universe is stretching away. Is it spaghettifying on a scale we can't really fathom?

I personally feel like there was stuff here before the 'big bang' and that the whole antimatter/matter thing seems a bit misrepresented, speculative, misunder-understood, over simplified. Yes whole universes of matter/antimatter could be floating around in a bigger universe and colliding and annihilating into what we see, while stretching into - or out of a bigger black hole. I think everything has a singularity in it's center, kind of like what ...

was that physisist guy who died before publishing his work in wwii thought?

In principle, a black hole can have any mass equal to or above about 2.2×10−8 kg or 22 micrograms (the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.

I think black holes aren't quite what we seem to understand and can exist on the smallest quantom levels, and the big versions we see just don't behave the same as the particles we see because we can't see them interact on the same time scales/relativistically.

Quantom stuff is strange, but not that strange.

Singularities within singularities seem plausible perhaps?

Also here's a fun picture of:

Did u know it has a magenetic tail that wobbles and spirals and allows its atmosphere to slowly escape? https://www.nasa.gov/feature/goddard...e-more-secret/

Here's a good one.
