>If one final black hole swallows all other black holes and is so big it absorbs all the light ever/energy becomes so big it implodes on itself could that cause a 2nd Big Bang starting our universe all over again,
There was an old theory called the Big Bounce that the Universe would collapse into a massive black hole and become another Big Bang.
But the discovery the expansion of the Universe was accelerating through Dark Energy and now we expect the Universe to continue separating at ever faster rates.

I don't how to explain when theirs no true direction.
But in plain simpleton terms - you see the south pole?
That galaxy that would be down towards that direction.
What's "down" there

Reply to NASA's 'Mega Moon Rocket' aced first flight and is ready for crewed Artemis II launch by sasko12
After numerous delays and enormous cost overruns, some worried that the SLS (nicknamed the “Mega Moon Rocket”) would never actually take off. But the launch in November went off (mostly) without a hitch, as did the 25-day mission undertaken by an uncrewed Orion capsule.

They’re all just rock or gas at this point though, we don’t know enough yet…

Well, I'm working on that. Check the "view history" tab on any page of that book to see who wrote it.
All your words that I quoted above are correct. Aside from robot arms and a 3D printer on the ISS, there is essentially no industrial capacity in space yet. Factories of the kind we build on Earth are too heavy to launch into space. So how do you get started?
A "seed factory", as I describe in that unfinished book, is a starter set of machines and tools that are used to make more machines to expand itself. This is where asteroid metal and carbon come in. Iron is by far the most important industrial metal, and 98% goes into making steel (iron with added carbon). Metallic asteroids are already in native form. They don't have to have the oxygen removed like iron ore on Earth.
The added machines are first to increase scale from the starter set, and second to make machines that work with other materials (glass, aluminum, etc.). You will still have to deliver some materials and parts from Earth while you bootstrap, but a lot less than if you tried to bring everything from Earth.
The starter machines can be as light as 20 kg, so certainly a single 100 ton Starship payload should be able to deliver a functioning machine shop with usable capacity.
You wouldn't jump into this without doing some R&D. We need to fly some asteroid retrieval missions in the ton rather than ~1 kg range coming back on the Osiris-REX mission. Ideally you want several different asteroid type samples. Then you feed those materials into pilot-scale processing machines and figure out what works and what doesn't.

Nope, not one mention of him...
The documentary is called Challenger The Final Flight. It was released in 2020 and it was made 4 different production companies one of them being bad robot.
After a little research into the people who had a major role in this shows product its even more strange that Roger had been left out as they had been close colleagues with him.

I’ve a feeling Boisjoly appears more in the last, if it’s the one I saw.

Exactly what I would be looking for as well. Especially surrounding the construction of significant megaliths and structures. And if there was some sort of extraterrestrial influence involved, we may be able to determine a rough direction of where it came from. Furthermore, moving the satellite closer to earth, at the appropriate speed, would provide a Timelapse of the last X amount of years.

The Hubble flow is indeed constant. Everywhere. We’re all saying the same thing. Cheers to you both, I think we all understand it well from the get go and now surely OP too 🥂

The characteristic note of our time is the dire truth that, the mediocre soul, the commonplace mind, knowing itself to be mediocre, has the gall to assert its right to mediocrity, and goes on to impose itself where it can.
– José Ortega
Please. Physicists spend decades trying to grasp how complex the universe is. Your shower thoughts are not ingenious nor do they contribute to anything but the collision between a few faces and the palms of hands.
