I recently came across a wikipedia article on carbonaceous chondrites, a particular kind of asteroid.

But what makes these awesome is that they are up to 20% water, contain amino acids (which is very interesting), and sulfur compounds and other biologically useful compounds.

To me it seems readily apparent that these things could of fueled the formation of life during the earths construction. But if these things brought life to earth, shouldn't we bring them to planets and moons we colonize? I mean, work backwards man.

A cool thought is that the first asteroid we bring to mars will be the beginning of its inevitable terra formation

Maybe we could build a giant lens in between mars and the sun. Tons of giant sheet like lenses layered over a huge distance, possibly all the way inside mercury's orbit, set up kind of like the death stars planet destroyer. The ones closer to the sun would be a mix of the future lenses and mirrors, concentrating the photons into a series of additional sheet lenses inbetween the sun and mars. The lenses in this part would play two primary functions, further concentrate the sun, and also block protons emanating from the sun, (assuming protons actually move in a straight line from the sun, I have a hunch they don't.)
Of course it would be a massive infrastructure project, be we're terraforming baby. The technology I'm talking about will also be here soon, if not on this scale.

Objects closer to the thing they orbit have a shorter period, though slower velocity than objects further out.
The interaction between two object's orbits produces 5 areas where technically an object could sit relative to the planet. In practice, objects don't remain there for very long (Lagrange 1 and 2 are particularly unstable) until reactions with the other bodies and the solar wind pulls them out, except for Jupiter, because Jupiter is fucking massive.
Any large sheets put outside a magnetic field in space will function like a solar sail, being pushed back by the solar wind it catches/deflects.
Magnetic sails work the same way, except they use an imbalanced in charged particles captured in a magnetic field to deflect charged particles.

And what if BEINGS like "angels" or "gods" existed in this "space"?
Could any "being" from this realm ever exist in this new concept of "space"?

If this was somehow proven to be true, what is the purposed of living here on a smaller, obviously now inferior scale?

Maybe I'm just too uneducated of a pleb in the realm of physics to see why this isn't the case, but can someone explain to me why, if we need to adjust our models with something that is 97% at least partially empirically unsubstantiated (dark matter-energy) then why don't we question first if there is some flaw in our model or bias in our thinking?
Thought experiment to exemplify: for the most part, we as biological beings as well as our most advanced instrumentation can detect faster than light particles in only the most abstruse ways; our perception, as is perhaps natural given our evolutionary heritage, is tuned to light. Might the supposition that no (or only special) particles go FTL be an example of circular thinking? Could not the existence of small but significant portions of the universe moving faster than light at any given time, such as ships from interstellar civilizations, or perhaps natural ftl phenomena which is invisible to our photon based instrumentation, account for the observed matter-energy discrepancy (given that an ftl object would disporportionately displace and deflect photons compared to any object moving in normal space, and that, if such ftl worked on means of creating geometric distortions in spacetime such as the Alcubierre drive, produce a net distortion on the observed mass of the universe by the fact of their mass negating local spacetime frames. )
This idea is cobbled together from wikipedia articles, some post-sec hard sciences, watching too much star trek and being turnt the fuck up. If someone more versed in physics can explain to me why there is a very good reason this cannot be the case, I'd very much like to hear it.

Don't lie, you asked why is dark matter the hypothesis that's winning. In order to explain that I need to tell you about the standard model.

>I am not calling them arrogant for no reason, but a very specific reason; the way they distribute the expenditure of their time and resources between pursuing the current prevalent theory, and investigating possible alternatives.

People who disagree with you are not arrogant. Cosmology is plenty diverse but you only get money for big experiments when you have something to show for it. It is not anyone else's job to spend their career on bullshit to satisfy your need to "diversity" the field. I you have a wacky idea go test it yourself. Alternatives exist and are tested.

>my claim of massaging was directed as a claim of potential bias throughout the system of statistical science, owing to observational and heuristic effects

Backtracking and handwaving. Massaging the data is not experimental bias, it is active and conscious manipulation to mislead. You are not confusing terms you are making extremely serous accusations without a shred of evidence. The reason I come back to methodology is because you made started throwing around slander like this.

>How is pointing out potential bias unhelpful?

You're not pointing to bias. You're pointing to the idea that bias could exist. NO FUCKING SHIT. Sating the obvious is not helpful. If you were actually pointing to a source of bias I would be happy but your pointing to the concept.

Not exactly. Dark energy is most commonly explained by the presence of a cosmological constant. It's a term in Einstein's GR which falls out in the derivation, Einstein famously used it to fix a relativistic universe to be static when really the equations would predict a collapsing or expanding universe in the presence of matter only. The cosmological constant seems perfectly capable of doing the job but there are concerns with it and particle physics. In a sense the cosmological constant is gravity as we understand it today.

The next idea is to remove the issues with particle physics and set the cosmological constant to zero. It is replaced with modifications to Einstein's gravity at large scales. These other gravitational models can also describe dark energy as it is observed.

The other idea is of course 5th forces like quintessence. These are often harder to test but predictive models of them do exist.

This is why dark energy experiments are so big right now because cosmology has built a bridge to particle physics and the fundamental forces can be tested on the largest scales.

Anyone else hear about this idea, I think its pretty clever. Building non-atmospheric water ice/liquid inflatable craft and using the water as a low thrust high impulse engine fuel. This design also, potentially, solves other issues like hull integrity, radiation shielding, self-sustainable life support and maybe even supplying oxygen and hydrogen gases.

So hear me out guys, getting on the moon is seriously important.

Why is it so expensive and difficult for us to send things to space? It's because of 2 things, breaking free from the Earth's gravity and surviving re-entry into the atmosphere. All of our rockets, satellites, space probes, etc. have to have a massive amount of fuel and ablative armor.
The moon is located in a strategically beneficial spot, right at the top of Earth's gravity well. Once we spend the initial capital to establish a permanent or semi permanent settlement on the moon, the door to space really opens.
We can then design our spacecraft without the need for massive thrust and armor, and wont need to spend nearly as much fuel to get around out there. It doesnt take much to move an object through space, and breaking free of the moon's gravity is exponentially easier than breaking free from Terra. And moving resources from the moon to earth is even easier, just a little push and they fall back to earth on their own. With even a tiny colony on the moon to act as a port of sorts, the trouble of monetizing space mining is essentially solved. Not to mention the insane amount of solar power that can be gotten from the raw, unfiltered power of the Sun.

We need to do this guys, we're quickly running out of several natural resources, rare earth metals in particular, which we're only just beginning to rely heavily on (theyre used in just about any battery, especially phone batteries and electric cars) and they can all be found in the asteroid belt. The Moon is the answer, and it's right at our doorstep. If we could get there in the 60's with the computing equivalent of a dollar store calculator, then we have no excuses to not go with today's technology.

>TL;DR- fuck solving world hunger or social issues, lets just go to the moon.

That's the rub. We need robots to set up all the essential resource harvesting before we get there. Of course if we can do that it's that much more difficult to convince the short sighted that humans need to go at all.

Besides that, present day humans just aren't suited to space. Homo Transfiguro (the cyborgs and bioborgs) will remake their puppets to suit the environment they're moving to as much as possible, and they'll (mostly the cyborgs) have much lower requirements for food, water and oxygen.

Here's my theory in a nutshell.

The universe is a high-dimensional object constantly rotating within itself.

A complete rotation takes the duration of the life of every universe in existence (current evidence only supporting one), with the big bang being the start of a new rotation. Matter and energy are the result of fluctuations within the universe as it rotates, physical laws are descriptions of how it rotates. Time restarts with each rotation, rotations end and restart after the heat death.

There must be natural rules to alien life, universal forms, just like the formation of mountains. If evolution is dictated by the environment, similar environments should create similar life. We are more related to horses than we are to deer, but similar habitats, similar place in the food chain, and similar food sources created similar animals, at least morphologically.

We won't be having hamburgers in space.

Or milk or eggs, for that matter. For every cow slaughtered for food there must be an incredible amount of food grown to sustain the cow. In space stations this may not be feasible due to limited space and resources. We'd be better off focusing energy on hydroponics and a vegan diet would probably be necessary in a long term colony or space station.

Why would you want to destroy a planet?
In the movie Dark Star, they blew up entire worlds because "instable planets" could threaten the future colonization of other planets.
Is it viable to blow up a planet to mine it as with asteroids? What other use could it have? Elimination of gravitatory perturbances in an Interplanetary Transport Network?
Blowing it up wouldn't send tons of material into chaotic orbits?

Sorry for too many questions. I just read about asteroid mining and thought about why not Jupiter with all that hydrogen?

>why not Jupiter
Because Jupiter is terrifying. Anything that approaches it gains ~134,000 miles per hour. To get away you have to give ~that much back.
To maintain an orbit just above the atmosphere, any craft would be going 90,000 miles per hour relative to the planet itself.
The difference in jupiter's gravitational interaction with the galilean moons' periapsis and apoapsis keeps their cores molten.
The ionizing radiation Jupiter emits constantly ablates the surfaces of its moons, giving the larger ones an atmosphere that's constantly lost to space and maintains a detectable ring of plasma from ionized particles that can't escape.

>Is it viable to blow up a planet to mine it as with asteroids?

no because you could just mine the planet instead of turning a single planet into millions of projectiles

>Elimination of gravitatory perturbances in an Interplanetary Transport Network?
i imagine transport would be more drastically completed by makes tons of asteroids whose paths are unknown

> just read about asteroid mining and thought about why not Jupiter with all that hydrogen?
we don't need that much hydrogen

Too bad Galileo failed to ignite Jupiter.

That would take a lot of energy, a ton of which would be released as heat. I think the debris would be too hot to be useful or mine-able for a LONG time.

I would be awesome if that dishwasher-sized satellite was the last tiny bit of mass needed to collapse Jupiter's core and start the fusion reaction.
