Follow the connections. Find your next question.
An accessible atlas of energy, intelligence, industry, space and human possibility.
The most interesting questions rarely stay inside one subject.
A computing system depends on energy and cooling. A remote facility depends on maintenance and communications. A robot's usefulness depends on what happens when the task changes. A space ambition becomes more meaningful when we can explain who it might help and what it would require.
This atlas lets you follow those connections. Begin with a topic, take a guided reading path or ask a question. You can explore practical engineering constraints alongside distant civilisation-scale concepts while keeping their different evidence levels in view.
If you are new to the subject, start with the big picture. If you want to build, follow the experiment pathway. If you are assessing a partnership, start with the founder's purpose and the work that exists today.
There is no prescribed conclusion to reach. The aim is a clearer understanding of the next question worth asking.
Guided reading paths
Curious readers
Start with the big picture
Build a clear understanding of the ideas before exploring the detail. Begin with the connection between energy, computing and human benefit, then move towards the more speculative horizons.
- 1Better living on Earth as the test of a space ambitionUnderstand the shared questions without assuming one predetermined future.
- 2Terafab: Why the Factory Itself Deserves ScrutinySee the physical systems beneath digital services.

- 4A Dyson Swarm Is a Question About Civilisation’s ScaleExplore the scale of the concepts and their hypothetical status.
- 5From a space vision to a testable software questionUnderstand the current project stage and how evidence will be assessed.
By the end: Explain the main concepts in plain English and distinguish an operating technology from a proposal or hypothetical structure.
Builders and technical collaborators
Move from idea to experiment
Follow a practical route through constraints, baselines, failure modes and reproducible evaluation. The aim is a well-defined experiment that can teach us something useful.
- 1From a space vision to a testable software questionDefine the operating constraint and the work that matters.
- 2What our first simulation actually taught usInspect the actual synthetic results and why the more complicated policy did not win.

By the end: Understand what GalaxyLink is proposing, what exists today, what remains unvalidated and where a partnership could produce evidence or customer value.
Glossary
- Artificial intelligence AI & Compute
- A broad field concerned with computer systems performing tasks such as recognising patterns, generating content, making predictions or planning actions. The term covers many different methods and does not itself establish human-like understanding.
- AI inference AI & Compute
- Using a trained model to produce an output from an input—for example, answering a question or classifying an image. Its computing requirements depend on the model, workload and operating conditions.
- GPU AI & Compute
- A graphics processing unit: a processor designed to perform many operations in parallel. GPUs are used in graphics and many AI and scientific workloads, although suitability depends on the task and software.
- High-performance computing AI & Compute
- The use of substantial computing resources, often coordinated across many processors or machines, to solve demanding problems. Workloads can include scientific simulation, engineering analysis and large-scale data processing.
- Data centre AI & Compute
- A facility housing computing, storage and networking equipment, together with supporting power, cooling, security and operating systems. Its capability depends on the whole installation rather than its processors alone.
- Kilowatt (kW) Energy & Earth
- A unit of power equal to one thousand watts. It describes the rate at which energy is supplied or used, rather than the total amount consumed over a period.
- Kilowatt-hour (kWh) Energy & Earth
- A unit of energy. A device using one kilowatt continuously for one hour consumes one kilowatt-hour. This is different from kilowatts, which describe the rate of energy use.
- Renewable energy Energy & Earth
- Energy drawn from sources replenished through natural processes, such as sunlight, wind and flowing water. Renewable does not mean impact-free, continuously available at every site or unlimited in a particular installation.
- Energy storage Energy & Earth
- A way of retaining energy for later use, such as a battery or pumped-water system. Useful comparisons consider both stored energy and the rate at which it can be delivered, along with losses and operating limits.
- Microgrid Energy & Earth
- A local group of electricity loads and energy resources managed as a coordinated system. Some microgrids can operate independently of the wider grid, but that capability depends on their design and controls.
- Power budget AI & Compute
- The amount of power a system is permitted or able to use under specified conditions. A computing site may need to allocate that limit among processors, cooling, networking and other equipment.
- Workload scheduling AI & Compute
- Deciding when and where computing jobs run. A scheduler may consider resources, priorities, deadlines and other constraints. A policy that improves one metric can worsen another, so the objective must be explicit.
- Checkpoint AI & Compute
- A saved state from which a computation can potentially resume. Creating and restoring checkpoints takes resources, and a checkpoint is useful only if the application and operating environment support reliable recovery.
- Digital twin Robotics & Industry
- A digital representation of a physical system used to analyse its behaviour, often informed by data from that system. Its usefulness depends on how accurately the model represents the questions being investigated.
- Robotic autonomy Robotics & Industry
- A robot's ability to perform specified functions with some degree of independent perception, decision-making and control. Autonomy is bounded by the task, environment and supervision requirements; it is not a guarantee of general competence.
- Orbital computing Space Infrastructure
- Computing performed by equipment in orbit. Proposed systems must address power, heat rejection, radiation, communications, launch, maintenance and useful workload selection. An announced architecture is not equivalent to an operating service.
- Space-based solar power Space Infrastructure
- A concept in which solar energy is collected in space and transferred for use elsewhere, often proposed for delivery to Earth. It is distinct from solar panels simply powering the satellite on which they are installed.
- Dyson swarm Civilisation Horizons
- A hypothetical collection of independent structures orbiting a star to collect some of its energy. It is usually discussed as an alternative to a single rigid shell, with substantial unresolved engineering and orbital-management questions.
- Kardashev scale Civilisation Horizons
- A framework for discussing hypothetical civilisations by their energy use. Its familiar categories concern planetary, stellar and galactic scales. It is a conceptual classification, not a dated technology roadmap or a measure of human wellbeing.
- Matrioshka brain Civilisation Horizons
- A hypothetical star-powered computing structure, commonly imagined as nested layers that use energy and rejected heat at different temperatures. It is a speculative concept with major physical and engineering questions, not a computer that currently exists.
