gherkinhead1:If there are billions and billions of stars - why is the sky dark at night?
I don't know where you live, to be asking a question of this magnitude. However, you may be living in an area of "light pollution". There are to many lights near you, such as a city, that when you look up, the light is reflected back at you from the water molecules in the atmosphere.
If you want to see the entire Milky Way, go out on the ocean at night. Chances are you will see something you have never witnessed in your life. You can also go to remote locations, that have no night lights, to achieve the same results.
LEDzZzEPP: imagine how far away the other stars will be that we can barely see them
Imagine that all the stars you can see, may very well have exhausted their fuel, and are dead. You would never know in your life time, as the stars are millions of light years from us.
A star that resides 10 million light years from us, explodes tonight. We would not see the last protons of light, until 10million years from tonight.
So, there is also the possibility that gherkinhead can see the future
Remember, all the physics man has ever postulated about, are theories.
"A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained".
Just because Einstein and all the other contemporaries, thought up the physics we know of today, does not mean they hold true, in the real workings of the universe.
I vehemently disagree, that, everything going into a black hole is crushed into a "singularity". Impossible. Hydrogen is the most plentiful substance in the universe. Stars are made of it.
I have postulated that hydrogen is spat out the other end of the gravity well, in it's atomic form. It comprises the darkness between galaxies, (dark matter) & is the reason the galaxies are moving further from each other.
Imagine that............
What do I know? I'm just a golfer.........
My grant money is on it's way from a Nigerian Prince, Whoo hoo
