Reply to comment by Bubbagumpredditor in How many years do you think we have until space travel? Something like cowboy bebop by Aware_Ad2047

Dude that’s accelerating 22 mph every second until you get there…

"You are technically correct, the best kind of correct."

Some may call it 'decelerating' for the second half, but in physics this also counts as accelerating (just in the opposite direction).

22 mph = 35 kph = 9.8 m/s = 33 ft/s

Yah but by the last second before deceleration on the first day wouldn’t you have to be traveling close to 2 million miles per hour? How’s that remotely feasible?

Yes, going ~850 km/s is not feasible today because we don't have torch drives like in The Expanse.

Torch drive / torchship is the generic term for the idea, an idea which has been used in various works of sci-fi. See more:
