You’d need to travel at around 233x the speed of light to make getting to the nearest star be a week trip, no?
- rbanffy 5y agoFrom the passenger's point of view, yes. For everyone else you'd be veeeery close to c, but not quite there.
- jsjohnst 5y agoMy point was it’s hyperbolic. You’d have to be going so close[0] to C that it’d be impossible. [0] about 0.99999c if what someone else in this thread said is correct
- samatman 5y agoNope! If you obtain the full speed of light then a) you're not made of baryons anymore so congratulations on that and b) no time passes whatsoever between your being emitted in some tight laser beam on planet A, and being transcribed on planet B, from your perspective. None. Photons don't experience time, they are time.
- rbanffy 5y agoNot exactly. For you to think you are traveling 20x faster than light, your friends that stayed at home would have to see you traveling at 0.99995c. For 233x faster than light, that's a lot of 9's in that number.

- s1artibartfast 5y agoThere is no faster than light, I can't parse this statement.
- psyc 5y agoDistance divided by [time experienced by traveler]. GP is not saying that traveler went faster than light.
- deleted 5y ago[deleted]
- s1artibartfast 5y agoI get 0.999c for 20x and 0.99999c for 220+
- rbanffy 5y agoI'll trust your numbers more than mine. But, for all intents and purposes, this is impossibly fast ;-) Unless you are on the Bistromath, that is.
- _Microft 5y agoThe effect is called time dilation. The section of interest here is „Time dilation caused by a relative velocity“: https://en.m.wikipedia.org/wiki/Time_dilation https://en.m.wikipedia.org/wiki/Time_dilation
- jsjohnst 5y agoI’m aware of time dilation, my point was that a “week vacation” to something “over 4 light years” away is just hyperbolic.
