Hi! I am Fotya the Squirrel!

My nut is a ray of light.
It is the fastest thing in the whole world!

Scroll down — let us play! ⬇

Light is the running champion 🏆

While you blink just once, the nut runs around the whole Earth 7 times!

Nobody-nobody runs faster than light. That is the main rule of the Universe!

Three wonders of light ✨

A ray is a letter. While it flies, time passes. Here is what that means:

☀️
The Sun from the past
A ray from the Sun flies to us for 8 whole minutes. You see the Sun the way it was 8 minutes AGO!
⭐
The sky is a time machine
A ray from a faraway star flew to you longer than your grandma has lived. Looking at the stars means looking into the past!
🌰
The nut never gets older
For the nut itself the whole flight takes zero little seconds! Even across the whole Universe. That is its biggest secret.

The two-paths trick ✨

This is real science! Scientists checked many-many times — that is exactly how it works.

The nut and the mirror 🪞

I will throw the nut at the mirror! Guess: when will I find out the mirror is there — right away, or when the nut runs back?

The past is like a sticker album 📒

Everything that already happened is like stickers already glued in. You can look at them this way and that, sort them into piles… but you cannot re-glue them. Nobody has ever managed! Not even the nut.

You are a little bit of a star ⭐

Zlata (age 5) said: “It is not us looking at the stars — it is THEM looking at us”. And that is almost science!

A ray from a star arrives — and your eyes CATCH it. It becomes a little part of you! So the Universe looks at itself — through your eyes. Thank you, Zlata, for the hint!

Our big riddle 🤔

What if the nut feels in advance what waits at the end of the path — a mirror or a trap? And flinches already at the start?

Quick! The nut is already flying — what shall we put at the end?

{{ ridResult }}

Nobody in the world has tested this yet! Papa Zhenya invented how to really test it. Scientists have not done such an experiment yet. That is our secret plan!

What we know — and what the riddle is 🧭

✅ Scientists have already checked:
✔ Nobody runs faster than light.
✔ While nobody looks, the nut runs along two paths at once.
✔ The squirrel learns about the mirror only when the nut comes back.
✔ Nobody has ever re-glued the stickers of the past.
❓ And here is Papa Zhenya’s riddle:
What if at the START the nut is a tiny bit different — when a mirror waits ahead and when a trap does? If yes — the future can whisper to the past! Nobody has done this experiment. We want to be first.
