Reply to Is there a part of space. Far away enough away from any celestial body that it would be unaffected by gravity? Not sure if I worded this question correctly but that’s my best try. by Itsasimulationnn
There are 5 low gravity spots in earth orbit. These are the Lagrange point. 2 are stable = items stay there, 3 are unstable and items migrate away unless actively maintained. L4 and L5 are stable - details here. https://en.wikipedia.org/wiki/Lagrange_point

Quite possible. Israel looks for planned raids. The bulk of the population want peace/prosperity so most tips come from these people as they see how Isis and other radical simply destroy their own peoples houses and businesses as part of extortion rackets.

In science fiction = straight. earth is in orbit, you in space are also in an orbit. If around the earth = gradual curve. Apply thrust and off you go on another orbit. Play with kerbal space videos = get the idea

Desert vary, some are fuller ecologically, others are alkali flats. The solar panels stand clear of the floor and have service columns, and the shade helps certain parts of the ecology do better - the ones that avoid sun

in isolated areas, with zero brush, fences and intruder alarms, people get discouraged

well, if we were at war. Perimeter walls and the isolation should work, as well as monitoring for intruders. lots of area.

Well, solar panels have not been vandalised in US desert areas. They can be fenced as well. In any event, solar does not atract terrorists and the isolation allows easy access control. The USA has enough desert areas to supply the grid. They do need storage by flow batteries as well as base load nuclear via thorium as well as wind. Some area also suit gravity storage as well. As time goes by these will all emerge as factors. As for losses, there are greater losses and harms from doing nothing and using coal/oil/gas

Well, the USA has enough desert to make the power. It also has the windy areas. STorage can be solved by titanium flow batteries. These never wear out, but they use space as the charge is stored in tanks of liquid. Capacity is limited by the tank size as well as the number of electrodes you use. Coupled with wind and solar, they can supply both coasts from central desert areas via ultra high voltage transmission lines. https://en.wikipedia.org/wiki/Flow_battery
Thorium base load nuclear is also good, 365/24/7 base load power.

Some effects, but not strong enough to use if it harasses marine animals.

Well, if your self assessment is correct, (possibly get tutored - as power systems seem to be a mature tech subject - what aspect is beyond you - tutor that) another discipline might work. A commenter dismissed your law aspirations - law differs from tech in many ways. There are the LSAT tests that assess the mix of skills/intelligence needed for law. You might pay to sit an LSAT (without any cheating) to get the LSAT assessment - then decide. As for space law, it will be a general overlay of a mix of western countries and (dictatorships like China - might is right) wrangling about it. The field will not be in full flower for ~~40-50 years - about when you retire and will not be a populous field until then? Have you ever taken the SAT tests - a high level IQ test. In my test year I was in the top 1% = engineer, but I lacked discipline for grad school and just became a rich butterfly... now retired at 83, I should have gone to EE instead of CE - as forced by admissions due to low CE entrants.

Do you lack the intellect to master these subjects or do you lack the discipline to work at until you master it - preferring any diversion/party etc. You might be a good candidate for Ritalin if so.

Hydrogen can be used for heating/cooking - the same stinky gas they add to natural gas works fine to alert people to gas leaks by people smelling the leak. The gas piping must be upgraded because hydrogen embrittles some alloys = they break. The gas jets and meters need to be changed. Some places used water gas, but it has been largely displaced by natural gas. https://www.merriam-webster.com/dictionary/water%20gas#:~:text=Definition%20of%20water%20gas,after%20carbureting%20as%20an%20illuminant
The truth is induction cook tops and heat pumps can heat/cook for about the same cost. All houses should be sealed to R2000 sealing and insulation standards and as we get rid of all gas types of heat and use electric we will be far better off.

Reply to Is the gold in or on the 16 Psyche asteroid by The_MrAwesomeTWITCH
All they know is 16 Psyche has a high density. The earth and 16 Psyche formed eons ago. Some speculate 16 Psyche is the core of a planet that was hit hard in a collision and blew off the rocky stuff - high density might be metal rich. Most common core will be nickel iron with some chrome with a scattering of other metals dissolved if the original planet was a larger. Earth has undergone billions of years of hydrothermal subduction and hydro thermal fluid transport from the deep crust driven by the water/CO2/SO2/Arsenic/silica etc. This hydrothermal fluid is lighter than the basalt, and gradually extracts gold as well as copper zinc etc into the fluid. When it gets near the surface the water/CO2/SO2 leave the fluid as gasses - some stay as carbonates/sulfides/silicates and they form layers - often around volcanos. In deep water they emerge and form nodules - which we can extract metals from. If 16 Psyche's host planet was too small for this = no metal concentration occurred. It waits for some laser bursts to the surface to do spectral analyses to know for sure. Psyche 16 may well be covered very deeply with waste rock gravitationally attracted to it that make surface analysis useless.
