The key is how dark your skies are. This is not a bright comet (Magnitude 5 last time I looked). That means it is just barely visible as a dim smudge with the naked eye in dark skies. It may not be visible if you are in an area with light pollution. The brightness does not change very much from day to day, so, if your skies are dark, then it shouldn't be noticeably harder to see it tomorrow than it would be today.

Well yeah, you might stretch a million dollars to last a lifetime, but that doesn't make you rich. It just makes you less poor.

To me, rich means never having to worry about money again. A million dollars isn't enough for that. You probably need at least ten million .

Actually yes, yes I do go ask them to correct it. Otherwise I would be stealing.

That's like saying that it's okay to not scan some of your items at a self checkout because it is the company's fault for getting rid of cashiers. It is still very much theft.

Alternarively, don't steal from people and pay what you owe.

Sure there is. If their answer is "yes, the weather IS nice today", then they had trouble hearing you

Reply to in the FAQ it is stated that one proof of the universe's expansion is that "more distant galaxies are packed closer together". What sort of measurements have been made to show this? by DanTheTerrible
Galaxies are usually part of a Galaxy Cluster, which is held together by gravitation. The expansion of the universe is not fast enough to overcome gravitational forces, so galaxies within clusters should not be any further apart now than they were billions of years ago. Even galaxy clusters are gravitationally bound into Super Clusters. There must be a large enough scale where yes, things are spread out more than they used to be, but I have not heard of any observational evidence of that (granted I have not worked in the field for more than 10 years now).

Reply to What would 2 stars colliding at relativistic speeds do? (1 solar mass, 10% of c) by Party_9001
There would be huge compression at the point of impact, which would cause fusion of very heavy elements and maybe formation of a neutron star. In a supernova, the compression from the collapsing star leads to a reverse shock which blows apart the outer layers of the star. That might happen in your scenario as well. In any case, you are going to end up with zero stars and lots of debris.

You are correct that SOMEONE has to be early. The problem is that there is no logical reason why the first intelligent life should just be arising now. Everything we know about the uni verse suggests that earthlike conditions should have been possible since the rise of the Population I stars (modern stars which seeded the galaxy with most of the elements heavier than helium). That was many billions of years ago. It only took humans a couple million years to go from upright apes to escaping our planter's gravity well. There is no known physical barrier to us colonizing the solar system and then the galaxy within a couple million years at most (assuming the light barrier can never be crossed). So, if intelligent life has been possible for billions of years and it should only take millions to fill up the galaxy, then where is everybody? That is the problem with saying we are at the beginning of the distribution. Everything we know says the distribution should have started long ago.

Reply to comment by araujoms in How do migratory birds know which direction they’re going? by YungPlugg
It has been well documented that migratory birds will get confused and circle certain sources of light pollution at night. Some will circle the same building/light source until they die of exhaustion

Some animals sense magnetic fields. Others follow the stars. Of course, it is pretty easy to tell what direction you are headed just by noting where the sun is. In the morning your shadow points west. In the evening your shadow points east. At noon your shadow points north (in the northern hemisphere)

But the sun can't go supernova. It doesn't have nearly enough mass. Instead, it will slowly swell into a red giant star in a few billion years and devour all of the inner planets, including Earth.

A telescope will help as long as there isn't too much light pollution
