what effect would it have on the earth if there was no stars in the sky?

Answer 1

Well, from a physical viewpoint, none, because teh light and energy recieved is minimal.

But from an evolutionary viewpoint, it would be disastrous.
We'd still be primitive people, probably living in caves or mud huts.
Consider this....

Without the stars, we would never have learned to navigate.
Without navigation, we would never have explored.
Without exploration we would never have traded with others and exchanged cultural traits.
Without exploration, we would never have needed armies and navies to defend our borders.
Without armies and navies, we would never have had wars.
Without wars, we would never have developed technology at the speed we did.
Without technology, we would still be primitive people.

Also consider, without stars, we would never have asked ourselves "Is there anything else out there?", and so no-one would have ever thought of space exploration.

Answer 2

If you don't include the sun as a star, it wouldn't have too much of an effect except that it would be a little darker at night. Before GPS, people used stars to triangulate their position and as a guide, but no one uses that anymore unless they are stranded or lost. So it might lower the human population (by about 3 people every 10 years).

The field of astronomy would also be set back immensely. This goes for if we couldn't see the stars. If the stars weren't there at all, our universe wouldn't exist as it does now, so we probably wouldn't exist either.

Answer 3

It would have a drastic effect on the weather on our planet. Clouds depend on the cosmic rays from other stars to create the higher clouds... without those cosmic rays the earth would be dryer and hotter. Out planet doesn't just cool when the Sun is less active because of the energy output of the sun it also cools because the lower solar activity also causes the magnetic field of the Sun to weaken and allow more cosmic rays to reach our upper atmostphere where they produce high elevation clouds that help cool the earth. Without those cosmic rays from the other stars our planet would not see the very cold weather patterns, only hot and warm.

Answer 4

Well, since the Sun is a star, the earth would probably be a lot colder and darker.
Assuming the sun can stay, and no other stars exist.....
Sailers would have had to find other ways to navigate in the days before the compass. Egyptians and mayan culture would be kind of drab. Nights would be a lot darker.
There would be no Zodiac readings next to the newspaper funnies.
There would be no gravitational effects or enviromental changes that we could calculate.

Answer 5

We would not be here. The galaxy would never have had enough gravity to hold itself together.

Oh my god - nearly everyone who has answered this is an idiot.

Yeah, yeah - the sky wouldn't be so pretty blah blah. But this is nothing compared to the fact that we SIMPLY WOULDN'T BE HERE TO NOTICE THAT.

Our little planet and sun are just a weeny part of a larger galaxy which is held together by a little thing called gravity. Every star within it exerts a gravitational effect on everything else, holding it all together. Without that influence we'd be free falling through space, little more than an asteroid, and life (us) could not exist under those conditions.

Sorry, your question is a very good one - it's the answers that are rubbish.

Answer 6

None.

There is not a significant amount of energy received from the stars.

Human history may have been effected by lack of navigation ability. Birds may not be able to fly north as consistently?

Nothing major.

The lack of stars in the sky would not make the sun in our solar system go away. It would not effect it at all.

Quit reading Spermipedia!!

Our solar system is not held together by external gravity it would be just fine.


My guess is that we would have less interest in all things celestial and would ignore the moon.

The aqueous creatures under the ice of Europa have the same problem. They can not see the stars. I have tried to communicate with the through interplanetary telepathy.

The moon people refuse to relay for me.

Answer 7

Life as we know it couldn't exist. All the energy for all living things begins from the sun. Plants capture this energy by photosynthesis, some animals aquire energy by eating these plants while other animals aquire energy from eating other animals (who would have eaten plants). Since the sun is a star, no stars=no sun=no plants= no herbivores=no carnivores=lifeless rock for a planet.

Answer 8

Their would be a pretty big aesthetic effect. Other than that, none. But rest easy. Except for the inside of a black hole, there is nowhere in the universe where you can't see a lot of stars and a lot of galaxies.

Answer 9

well if there were no stars whatsoever then i don't know about the earth itself, but i know the human race and plants wouldn't survive. humans and plants need the sun to survive and the sun is a star

Answer 10

we would die because the sun is a star and without it plants and trees wouldn't grow animals would die there'd be no oxygen, we need stars to navigate if we're lost at sea or in the woods

Answer 11

Hi. You mean just visible? Venus has no visible stars for instance. If you mean "Really nor there" then I don't see how anything other than hydrogen could exist.
