Spacetime: real and physical, or a calculational tool?
Interesting article about Space-time. This was posted to the fediverse on the StartsWithABang @[email protected]
This is interesting, even if it may be hard to get your head round it sometimes. There is an activity we could try and do at the STEM group that will demonstrate the warping of space around a mass. This isn't complex to do, just needs the right materials.
As always we can discuss on Science forums or on the Fediverse.
