omg what do you expect to see??
*prepares camera for the supernova that isn't coming* .......nothing.
Wouldn't the gravitational wave be able to significantly travel faster than the light of the explosion?
Nope! Speed of waves (gravitational waves are just waves!) in a vacuum max out at C (light speed)
This is starting to blow up so if anyone likes science-fiction and also wants to help the Australian fires and relief, I write books and am currently donating to @RedCrossAU with each book sold.https://twitter.com/SidewalkSciGuy/status/1216431527715844096?s=19 …
If anyone is looking for in-depth information about supernovae, I highly recommend following @starstrickenSF! She's much more qualified than me to discuss details and last week, DISCOVERED A SUPERNOVA OF HER OWN. Go learn all about them and her!https://twitter.com/starstrickenSF/status/1217264993738973187?s=19 …
And other question: do gravitational waves take time to travel? Or like, is it possible that Betelgeuse exploded *now* so we felt the gravitational wave, but we'll only see it in 640 years due to light speed?
They travel at speed of light! Kind of like dropping something into a bowl of standing water. No matter the height/force you drop an object into water, the waves travel the same speed! Every medium (various liquids, solids, gases) have intrinsic wave velocities
