How long is the way to the edge of the universe?

About 270,000,000,000,000,000,000 miles separate us from the edge of the observable universe.

It would take 480,000,000,000,000 – or 4.8 1017 – years, or 35 million times the age of the universe, to get there if you traveled at 65 miles per hour.

How do you feel?
Send it to a good question if a science puzzle keeps you up at night.

This wild journey will be fraught with dangers. Not because space matters. We don’t worry about that. I mean because driving is so dangerous. In the United States, a middle-aged driver experiences one fatal collision for every 100 million miles.

The majority of motorists would not be able to get past the asteroid belt if a highway was built outside the solar system. Truck drivers have a lower crash rate per mile than other drivers because they are used to traveling long distances on highways, but they are less likely to reach Jupiter.

It would take a lot of fuel to make this trip. A moon-sized ball of gasoline would be needed to travel to the edge of the universe at 33 miles per gallon. (As of 2021, NASA’s New Horizons spacecraft has traveled about five billion miles on a budget of about $850 million, or 17 cents per mile, which is roughly the price of gas and snacks on a road trip.)

You’ll go through a 30 quintillion oil change, which requires an engine oil container the size of the Arctic Ocean. Modern gasoline engines can comfortably go two or three times that distance between changes, contrary to the adage claiming that you should change the oil every 3,000 miles.

1017 tons of snacks are also required. If there aren’t many intergalactic stops, your trunk will probably be quite full.

The landscape won’t change much at all, and the ride will be very long. Before leaving the Milky Way, the majority of visible stars will burn out.

I’d recommend mapping a road running through Kepler-1606 if you want to try to touch a star at room temperature. It will have cooled to the pleasant room temperature when you exceed it in 30 billion years because it is 2,800 light-years away. Although this planet will most likely be gone by the time you arrive, it currently exists.

After the stars fade, you’ll need to find another form of entertainment. You won’t even get to the edge of the solar system if you bring every audiobook ever made and every episode of every podcast.

According to the famous estimate by British anthropologist Robin Dunbar, the average person maintains 150 social connections. There are likely more than 100 billion people who have ever lived. A road trip of 1,017 years would be enough to re-view the lives of each of these individuals in real time, resulting in a sort of unedited documentary. Then, each documentary will be re-watched 150 times, with a different commentary track given by 150 experts on the subject.

You’ll still be less than 1% of the way to the edge of the universe by the time you finish watching this comprehensive human perspective documentary, so you’ll have plenty of time to watch the entire project all over again – every human life with everything 150 tracks to comment – 100 times before you finally arrive .
