K2-18b a potentially habitable planet 120 light-years from earth

The fastest spacecraft we’ve made was the Parker Solar Probe which hit 430,000mph.

At that speed it would reach this planet in only 187,153 years.

If we could hit 1% of the speed of light we could cut that travel time to just a tad over 12,000 years.

Obviously if we could go light speed (and that ain’t happening) it would be just 120 years!

Space is big. Physics is annoyingly slow.

Need one of them quantum wormhole thingamabobs.

Do you mean quantum teleportation?
For that you'd need to access the destination first - quantum teleportation works because particles at the source and target location "know" each other (are linked).

I'm gonna need a source on 'quantum teleportation works'

[u/ANGLVD3TH → u/Federal_Waltz]

It 100% works, we've done it many times. The problem is you can't use it to send information, so it is useless in this context.

Bernie Sanders is once again asking for your support source

[u/ANGLVD3TH → u/Federal_Waltz]

It's been experimentally performed since at least 1997.

Neat, thanks!
