is is a nanosecond the smallest time unit?

Question

is is a nanosecond the smallest time unit?

Answer 1

The smallest unit of time is Planck time which is the time it takes for a photon travelling at the speed of light (well what other speed can they travel) to travel across a distance equal to a Planck length (1.6 x 10^-35 m)

The time is 5.39 x 10^-44 s.

Arguement:
If planck length is the smallest length with any physical significansce, and the speed of light is the fastest speed (eg information cannot be transferred faster than the speed of light, then it makes sense that smallest unit of time must be the Planck length divided by the the speed of light.

Answer 2

No. Time is linear. A picoseconds 1s 1/1000 nanosecond.

Answer 3

there are many smaller divisions of time than a nanosecond. Picoseconds and femtoseconds are the next metric divisions. 1000 picoseconds = 1 nanosecond, and 1000 femtoseconds = 1 picosecond...You can continue to divide them even smaller, I just don't remember the prefixes.

Answer 4

planck time ¼ 335 decicentillionth Δ (10^33) of a attosecond. wich is 1/100 of jiffy wich is 1 google of a second. it's named after how long light takes to travel a Planck in a vacuum in space 180'000th/ millimeter.

Answer 5

no, there are lower units of time, pico(10^-12), femto(10^-15), atto(10^-18), zepto(10^-21), yocto(10^-24)
etc, etc, etc.....Theoretically there is no end to how small a number can get, you can keep taking the number out to smaller and smaller decimal points
.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

Answer 6

no, time can be divided as little as you want. I mean, after a point, you can't really measure it, but you can theoretically talk about it still.

As in, you take 1 second, divide it into 1000 intervals of 1millisecond each, take each of thsoe milliseconds and divide it into 1000 intervals and call those microseconds, then take each of those microseconds and divide it into 1000 and call those nano, then you can take those nano and divide it into 1000 and i don't know what they're called, but ya. and you can keep going.

Answer 7

time and math are almost intretwined as both are infinite. until one can measure one smaller than the ones measured it just wont have a name. I am sure something happens that occurs in 1/ 1,000,000, 000, 000, 000, 000, 000, 000,000 of a second. the same goes with counting; who says you cannot add one more?

Answer 8

You can divide it so much that if you lived for 1 trillion years, you still couldn't finish dividing.

Answer 9

No. Picoseconds, femtoseconds, attoseconds, yoctoseconds, etc.. all much smaller.

Answer 10

...I'm not sure... lately, tho, making love with my girlfriend seems to be the "smallest unit of time"...
