C is very large. Nothing goes that fast normally. Not by orders of magnitude. So 2% is huge. Our sun moves about the Milky Way at 828,000mph. 2% of the speed

C is very large. Nothing goes that fast normally. Not by orders of magnitude. So 2% is huge.
Our sun moves about the Milky Way at 828,000mph.
2% of the speed of light is around 13,000,000mph
That's the speed where relativistic effects become important.
- taeric 6y agoStill doesn't mesh with the colloquial "nearly". :(

- yesenadam 6y agoI think your sun speed should be km/h? Every website has a different figure, but they mostly seem to be around 500,000 miles/hr ~ 800,000 km/h.
- JoeAltmaier 6y agoYeah missed that, thanks. 536,000mph
- gpvos 6y agoThose two numbers are actually closer to each other than I expected.
- ganafagol 6y agoWhere they become important depends on your precision of measurenment. GPS satellites don't move at 2% the speed of light, but relativistic effects do play a role for the system to work since they need to be very precise in measuring and broadcasting time.
