will earth be affected in anyway by moving through a neighboring interstellar cloud, such as the g-cloud?
i’ve heard people (mostly conspiracy theorists) claim that the g-cloud will “block out the sun” or that it “contains dangerous particles.” is any of this true? could earth be harmed once we leave the interstellar fluff and enter the g-cloud? https://en.m.wikipedia.org/wiki/G-Cloud

Interstellar clouds are incredibly thin. The solar wind from the sun will push all interstellar particles away. They will not block out sunlight. None will ever reach earth or even enter the solar system.

it would be quite difuse
There would benothing of real Mass to worry about
In fact some of the substances could be put to use, like compacted and used for rocket fuel say
We could probably get a nightly light show of meteors from particles falling from space
Your average Comet has the constituency of Cigar Smoke for comparison

these are just idiot replays of the 1910 warnings of widespread calamities from the noxious gases in the tail of Halley's Comet. The density of any interstellar nebula approximates the density of the best vacuums we can make on Earth

The molecules in the clouds are so rarefied, that only sensitive instruments will be able to detect any 'drop' of light coming from the sun; the effect on Earth won't be noticed.

Those "clouds" are incredibly tenuous. They pose no danger to the Earth.
However, yes, they will affect the Earth.

Everything that we can detect in space affects Earth to a large degree. We don't notice because we don't have any baseline with which to compare.
Here is a “thought experiment”:
Imagine that you can go back in time and make a small change and then compare the resulting situation with the way things are today without that change. You go back in time to 2 years before you were born and the only change that you make is to deflect one single photon to Earth that otherwise would not have reached here.
That photon is absorbed by an atom in the atmosphere and changes the energy of its electrons, changing its frequency and Brownian motion. That atom constantly bumps other atoms at incredible speed. In minutes, every atom of the entire atmosphere is in a slightly different location. That would seem to make no difference.
Consider that before a person’s conception, millions of sperm are jostling around until one reaches the egg. The change of one atom may not affect the sperm enough to change its course, but “all” of the atoms are in different arrangement. The bumping and jostling is completely different. After the change you made, it is very unlikely that the exact same sperm would have reached the egg. A person may result, but not the same person with the same DNA. Jostling during DNA recombination would also be a factor. This type of change also affects every other living thing on Earth.
When you compare the resultant changes with the way the Earth is without those changes, the difference will be enormous.

the g-cloud does not exist. the operative word here is conspiracy. they are a bunch of idiots
do you wan to be an idiot also or stay in reality? If this "G" cloud were coming it would be all over the news. You cannot hide something like that
