What If You Could Time Travel is a free interactive history explorer that lets you visit any era from 10,000 BC to 2100 AD. See what technology existed, what you'd eat, your biggest dangers, and what daily life looked like — all backed by real historical data across 16 detailed time periods.
Use the time slider or tap preset era buttons to jump to any period in history. Each era shows 8 categories — technology, food, danger, medicine, transport, communication, lifespan, and daily life.
Life expectancy in ancient Egypt was 35-40 years, in medieval Europe about 30-35, and in ancient Rome around 25-35. These averages are heavily skewed by high infant mortality.
The Black Plague era (1347-1353) killed 30-60% of Europe's population. The early Ice Age was also extremely dangerous due to predators and starvation.
By almost every measurable metric — life expectancy, child mortality, literacy, poverty, violence — the present day is the best time to be alive in human history.
