I'm a wannabe amateur astronomer making do with satisfying my urge by taking astrosolar photographs in white light with available equipment.

comment How do we know that the speed of the influence of gravity is instant?
@Supuhstar you could be a bit more helpful and instructive to help a new user make better answers instead of being dismissive. I note you are fairly new yourself. As a counterpoint, your question was not a 'good' question, in that it showed little prior research, and asked about a personal understanding that wasn't correct. Please check the FAQS for how to ask good questions.

comment How much would you weigh if Earth stopped orbiting the Sun?
I think this question falls squarely in the category of hypothetical questions that are in the 'don't ask' category, and I am flagging it for moderator review. astronomy.stackexchange.com/help/dont-ask

comment What is the bluest narrow band filter mounted on ground based telescopes?
The issue doesn't appear to be whether a filter could be made, they don't seem to exist off the shelf because there is no point, as the atmosphere doesn't permit observations at the desired frequency

@Err I think this answers your question well, addressing you misconceptions about weightlessness in gravitational freefall.

comment How can a planet not rotate at all and yet have 1 year that is day and 1 year that is night?
@Scottie a tidally locked planet doesn't have (solar) days (and nights). But though it might be news to you, Mercury is not tidally locked, and this is old news. See my answer.

...and the question is essentially asking about sidereal days on Mercury, not solar days on exoplanets.
