Hi, we're here from curiosity.com to help you get smarter in just a few minutes.

Today you learn how scientists discovered that Neanderthals actually walked upright and why

hangovers seem to get worse with age.

But first we'll answer a listener question about how quickly you'd age if you could move at the speed of light.

But it's out of some curiosity, at the speed of light.

We got a listener question from Iman in

Bangladesh who says I am 15 years old and I have rotated around the sun 15

times now. If I move at the speed of light and rotate 15 more times around the sun, then what will be my age?

And will I look old?

This is such a fun question.

To know the answer, you first have to know the distance the Earth travels in its revolution around the sun each year.

That distance is roughly 940 million kilometers or about 580 million miles.

In that case, over your 15 years on this planet, you've already

traveled 14 billion kilometers. And that's not counting road trips. Okay, so the

speed of light is about 300,000 kilometers per second or about 186,000 miles per second.

That's really fast. It's so fast that to cover the distance Earth travels around the sun in one year it would only take you

52 minutes less than an hour if you did it 15 times in a row at the speed of

light it would only take you a measly 13 hours. Isn't that wild? The entire distance you've

traveled in 15 years at the Earth's regular speed would take about half a day at

the speed of light. Obviously if this whole trip took you 13 hours you wouldn't look old.
