I’m actually talking about shutter speed. Like holding it open Long enough with aid of a tripod to accumulate time and light so that it can be burned onto film to where you can see things that can’t be seen at the speed of light by the naked eye. But I’m just a time traveler from 1977.

This is actually pretty puzzling. B was thought to have the thickest atmosphere of all the planets because of its low apparent density. This could mean all the planets have underestimated densities, or maybe their composition on a whole is very different from our solar system.

Btw, I was under the impression that Starship couldn't do GTO missions while being reused and would need a refueling mission or kick stage. Apparently that is not the case. According to SpaceX's Starship User Guide, they can put 21t into GTO while still recovering the booster and upper stage at the launch site.

By comparison, Falcon Heavy can only put 26.7t into GTO while being fully expended. And the heaviest payload to GTO so far (by SpaceX) is only 7t, according to SpaceXStats webpage. And it appears that the heaviest payload ever by SpaceX is only 17.4t back in January, according to SpaceFlightNow.

I was reading the other day, and it was also verified by how the universe works (but don’t quote me exactly) that a galaxy is interconnected not just by gravity, but also magnetically through magnetic fields that interconnect everything…. So someone smarter than myself please explain that more, but that was the general gist… please forgive I think it’s basically the hardest thing to get your head around :) you know I took a small course on quantum computing recently and the concepts of quantum in relation to the universe is so hard to comprehend when you start getting down to sub atomic levels…

Not to mention the dark matter that helps keep the galaxy together (gravitationally)

That’s the one that all of those people ate poison pudding and died so they could get on the comet and fly home.

I mean it is one planet out of quadrillion but yes I get what you're saying it's making people afraid that the most abundant planets around red type Stars where most life in the universe will have a chance to live for the longest period of time it's scaring people that the Stars may be violent and may strip atmosphere and there may not be as much chance for life in the universe as a result but still I would caution that it's literally one planet

A) good info!
B) homework now is to do a search for starry skies in the Southern hemisphere that show the Magellanic Cloud

Thanks for answering

If I had the money, this is the kind of stuff I would do.

Disco ball?

This is a good explanation but there’s also just the simpler fact that if things can’t collide (and dark matter is mostly collisionless as famously seen in the bullet cluster) it’s hard to get it to “stick together”. So while gravitational force will get it form “dense halos” it’s fairly unlikely you’ll get something like planets or stars.

Closest planet to star, so most transits, so most data to analyze.

They modeled several scenarios and this temperature almost exactly matches an airless black rock.

No, the black hole is an essentially insignificant portion of the galaxies entire mass. The galaxy is orbiting it's own collective mass not the black hole.

For reference, Sag A* is about 0.0007% of our galaxies mass. It's gravitational attraction on our solar system is completely insignificant compared to the rest of the galaxies mass.

Our solar system orbits the galaxy at about 230000 m/s. Sag A*'s escape velocity at our orbital radius is about 2090 m/s. If the rest of the galaxy vanished, we would go flying out into intergalactic space, since we aren't even close to being gravitationally bound to the black hole.

No. Galaxies and their black holes form together.

No, since the black holes themselves don't generally have anywhere near the gravitational attraction to bind all of the galaxy's matter gravitationally itself.

The expansion speed is also constant across the space dimensions. Which is a bit strange, because that breaks the speed of light limit.

Not all galaxies have super massive black goles.

I want to know this too. Things have changed since I was at school.

Shit. Send a message to that ship we dispatched 20 years ago. Tell them to turn around. Oh, boy are they in for a rude surprise if this message doesn't reach them in time. 😬

Why bother with a dyson swarm when you can get perfect utilization of energy with an antimatter engine.

At least ssk the planet out first!

Maybe you need to rub some crystals!
