Why haven't aliens visited Earth? What if they have - but not in the way we expected?

What if the answer to the alien mystery isn't out there… but in our own future?

Drawing on cutting-edge science, ancient clues and modern UFO phenomena, this book explores the provocative idea that the beings we call "aliens" might be time-travelling descendants of humanity, evolved over millions of years into thin, grey, large-eyed post-humans - returning to the past to observe the dawn of civilisation, or possibly to retrieve lost knowledge or genetic heritage.

Alien UFOs and the Heliosphere takes readers on an electrifying journey across science, speculation and the limits of our cosmos. This thought-provoking book proposes a radical new hypothesis: that intelligent life may be far more limited by the structure of space itself than we've ever imagined.

In this book, you'll discover:

The protective role of the heliosphere and how it shapes the potential for alien contact.

Why interstellar radio silence may be an illusion caused by the physics of space itself.

Whether the classic "Grey" alien could actually be a future human.

How astrobiology, evolution and time travel intersect in surprising ways.

Why we might be alone - or not - in the habitable zone.

Alien UFOs and the Heliosphere is a thrilling, intelligent and accessible guide to one of the greatest cosmic mysteries of our time. If you're a ufo believer, a skeptic or simply curious, this book might change the way you look at the night sky and at yourself.
