If the sun were to explode would the effect on Earth be simultaneous or would the explosion of the sun affect the Earth after eight minutes
AI Thread Summary
If the sun were to explode, Earth would not experience the effects immediately; instead, there would be an eight-minute delay due to the time it takes for light and gravitational changes to reach our planet. The sun's gravitational influence would persist even after the explosion, as its mass does not vanish instantly. Observers could measure changes in the gravitational field as the explosion's energy propagated through the Solar System. This scenario has been a topic of speculation and discussion in various forums. Understanding these dynamics highlights the complex relationship between celestial events and their impacts on Earth.

The Earth will only notice the change after eight minutes. This has been discussed many times, just recently in this thread: https://www.physicsforums.com/showthread.php?t=149144 (Caveat lector--not every post in that thread is accurate.

BTW, I know you're just speculating about a hypothetical circumstance, but do note that, even though the Sun explodes, it still continues to have a gravitational influence. The mass doesn't simply vanish.
You could measure the drop in the gravitational field as the shell of mass and energy approached, passed and expanded out into the Solar System.
Nature abhors a vertical slope.

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
