Of course not, for that you need to travel into a black-hole.

If we are talking about the measurement of gravitational waves - indeed - it IS the curvature of spacetime (a resultant effect of the gravitational wave) that the LIGO experiment successfully detected.Terrapin Station wrote: ↑Thu Jan 28, 2021 11:16 pmFor you to realize that we're not actually observing space or its curvature.bahman wrote: ↑Thu Jan 28, 2021 11:11 pmWhat else do you expect?Terrapin Station wrote: ↑Thu Jan 28, 2021 11:00 pm

Re: Plank length and what is between
Well of course they use lasers - the most accurate measurement device at our disposal to detect such an infinitesimal small thing as a fluctuation in SPACETIME - they are however, detecting the curvature of SPACETIME - space and time cannot be separated otherwise calling such a things as a 'gravitational wave' is redundant.Terrapin Station wrote: ↑Thu Feb 04, 2021 2:58 pmWhat was detected was changes in a laser set-up.attofishpi wrote: ↑Thu Feb 04, 2021 6:40 amIf we are talking about the measurement of gravitational waves - indeed - it IS the curvature of spacetime (a resultant effect of the gravitational wave) that the LIGO experiment successfully detected.Terrapin Station wrote: ↑Thu Jan 28, 2021 11:16 pm

Re: Plank length and what is between
No. We're detecting changes in the laser set-up. We theorize that those changes have something to do with a spacetime curvature, based on particular ontological views about what spacetime is (among other assumptions). We don't literally observe spacetime (and on my view, this is because spacetime is not a substance of container of any sort of whatever in itself)attofishpi wrote: ↑Fri Feb 05, 2021 1:21 am

Re: Plank length and what is between
The lasers detected the fluctuation of gravitational waves - sure measured the difference in the speed of light within the wave, but this still couples with the effect of what a gravitational wave IS - spacetime curvature.Terrapin Station wrote: ↑Fri Feb 05, 2021 2:15 pmNo. We're detecting changes in the laser set-up.

In any case, some people might like to watch this regarding the topic of LIGO and gravitational waves - it goes for 1hr40mins hosted by Brian G.

Re: Plank length and what is between
Plank length is NOT a literal quantizable 'minimum'. It is defined in a way that others can determine a unit without a particular 'standard', like the original 'meter' being defined by a particular bar's length, for instance. When using literal standards of length, it is hard to use macro-objects (relative to quantum sizes) given they can be affected by temperature differences, material used, etc. It may also be the present smallest agreed to unit (conventional minimum), but it doesn't mean that there is some actual smallest interval greater than zero other than AT an interval of zero size, which would just be a point. But there are still paradoxes about spacial measures; just not related to the Plank length.bahman wrote: ↑Sun Jan 24, 2021 1:33 am This is believed to be the shortest distance between two points in space so-called Plank length.

Following the same logic, it follows that time also is a substance.
I understand that this measure is a 'limit' of practical means of measuring. For instance, our fingers are of such a size that there is a limit to what we can use fingers. Plank is a limit based on the smallest means of measuring a specific unit size. The same goes with 0K, a measure that can only be inferred (as a singularity) but not something you can measure because at that temperature, no movement exists. So you cannot 'measure' it without CAUSING such points in space being measured to have some minimum limit.
