I got thinking what is the fastest speed obtained by things, including living creatures, here, in the sea, and out in space. I bet you all know what the fastest land animal is, right? No, it isn't the hare or the tortoise, it is the Cheetah. Not only does it hold the title for the fastest top speed, it is also not a slouch in the acceleration department. Its top speed is 75 mph and it can accelerate from 0 to 60 mph in 3 seconds. Yep, I don't think you could outrun a Cheetah.
So, what about in the water? That would be the sailfish and 68 mph. In the air? That would be the Peregrine Falcon at over 200 mph.
Then there is things that mankind has ridden on or in. We have come a long way from horseback to the fastest street legal car, the Bugatti Veyron EB 16.4 which can reach 268 mph. Wouldn't do much good here during the Houston rush hours.
In the air, it would be the North American X-15 at 4520 mph. Heck at that speed I could fly to either the West Coast or the East Coast for my lunch hour and not be late getting back. Just think about how really fast that is!!
Back a few years ago the military was experimenting with rocket sleds. Do you know that they managed to reach mach 8.5, of course there were no humans riding on those.
I am sure you have heard the term "escape velocity". A rocket has to reach at least the minimum speed that is required to break free of Earth's gravity and this speed is called the escape velocity. Well did you know that our galaxy also has an escape velocity? Yep, in order for anything to exit our galaxy, it has to reach a minimum speed of 1,230,000 mph. Now let's see your Bugatti do that? Now, slow down a bit and have a great day, you hear?
Galaxy's escape velocity - 1,230,000 mph
