Post Something Interesting

If you go back to me answering PC, he said if it happens tomorrow. or in our lifetime….

Ok maybe I was being a bit facetious but I was taking his description of time literally. If Betelgeuse explodes tomorrow we’re not going to witness it with or without telescopes. We’ll be long gone by the time the light travels here.
However if he meant if we detect this tomorrow, what we would be witnessing is something that happened a fair while ago.

Does that clarify my thoughts.

Yes mate. It was just this bit I was confused about. I didn't realise you were being facetious

So we’re not going to see it in our lifetime as I’d say it would have been detected by Hubble or JWST before now.

Elementary my dear Watson.
Apparently Holmes never said that in any of Arthur Conan Doyle’s books.

Loved watching Sherlock Holmes when I was a kid with my dad,the old Black & White ones with Rathbone and Nigel Bruce the dithery Watson.

I thought Jeremy Brett was the best Holmes

Rathbone and Bruce always for me.

However, it's currently orbiting about 1 million miles away and light takes an additional 4 seconds to reach us here. So basically the light from Betelgeuse (the star we're discussing) takes 4 seconds longer to reach us. How would JWST already know if the star had exploded?

If it’s orbiting, it might take 4 seconds longer to reach JWST if it’s on the far side of the orbit relative to Earth/Betelgeuse…

If you can’t get pissed and fall over, what is the point of travel insurance?
