For anyone curious about space but put off by technical language, this course explains the universe clearly, from your garden to the observable universe. You will learn how light records cosmic history, why space is not empty, and how gravity shapes orbits, tides, stars and galaxies. Explore the lives of stars, the evidence for black holes, and the worlds of our Solar System. You will also consider Earth’s life-support system, the search for life beyond it, and how viewing our planet from space can change our understanding of shared systems.

Topics Cosmos Universe Overview Effect Astronomy Space Exploration

What you will learn

Map your location from a garden fence to the observable universe using a clear cosmic scale

Describe how gravity shapes orbits, tides and the sensation of weightlessness for astronauts
Interpret the life cycle of stars, from fusion-powered shine to supernovae, white dwarfs or neutron stars
Assess Earth’s fragile systems using satellite imagery and the overview effect to foster a balanced space perspective

Why it works

A mentor, just for you

Every call starts from where you are. No recapping, no repeating yourself, no starting over.

It picks up where you left off

Nothing you say gets lost. Each call builds on every one before it, so you keep moving forward instead of going over old ground.

Time goes on your weak spots

It knows the questions you skipped and the quiz answers you missed, so the call is spent where it helps most.

It meets you at your level

Flying through? It pushes you further. Finding it tough? It slows down and tries another way in.

It keeps you on track

Every call is about the part of the course you are on now, not wherever a chat happens to wander.

It makes it stick

Putting an idea into your own words, out loud, turns "I read that" into "I know that".

How it works

From checkout to your first call

No app to install and no link to click. It is a normal call to your phone.

Step 1

Buy the upgrade

Voice Mentor includes the whole course, so there is nothing else to buy.
Step 2

Pick your time

Add your number and choose when the first call rings. The rest follow a week apart.
Step 3

Answer and talk

It quizzes you on that part of the course and gets you explaining it in your own words.
Step 4

Each call builds

The next call is briefed with everything from the calls before it.

FAQs

A few straight answers

Anything else? Read more about voice mentoring.

Yes. A normal call to your phone number. There is no app to install and no link to click. You just answer.

No. The lessons are yours to read. The call is you explaining the ideas in your own words, while it asks questions and builds on what you say.

Not on its own. Before each call it is sent the summary and full transcript of every call you have had on this course, so nothing gets lost between them.

The course is split into four parts, in order. Each call focuses on the next part, with the rest of the course there for context.

You can still take the call. It sees which prompts you have answered and how long you spent on each lesson, and works from there. It goes better if you have read that part first.

If you know you will be busy, move it before it rings. If one slips past, get in touch and we can usually rebook it. The next call still picks up from everything you have done.

You pick the day and time of the first call. The other three are booked a week apart after it, and you can move any upcoming call to a time that suits you.

It is used only to place your mentoring calls. It is never shared or used for marketing.

For about ninety seconds. Then it is just practice. It does not judge and it does not get bored.

No. Voice Mentor is the full course plus the four calls. Standard is the same lessons, without the phone.
