Here is some of my knowledge that i have on black holes.

(Question 1) What is a black hole.

(Answer) A black hole is something that is so dense, that it distorts that fabric of the universe, its gravitational pull is so intense, nothing can escape from it, not even light. To escape from a black holes event horizon, you would have to travel faster than the speed of light which is imposable as nothing can travel faster than light which is at (186.000) miles per hour.

(Question 2) How is a black hole made.

(Answer) A black hole is made after the death of a star, a supernova.
The core of the star becomes so dense, that it collapses within its self, forming a hole in space time.

(Question 3) Will our sun become a black hole when it dies.

(Answer) No, in order for a star to become a black hole, it must be more than double the size of our sun. Our suns fate will end with it turning into a red giant and ending up as a white dwarf in approx, three to five billion years time.

(Question 4) What is the biggest black hole known to us and where can it be found.

(Answer) The biggest black hole known to us is called (OJ-287).
It weights in at three billion solar masses, three billion suns.
It is located at the heart the galaxy M87.

Here is my knowledge about galaxy's

(Question 5) What is the name of our galaxy

(Answer) Our galaxy is called the milky way, it is 100.000 light years across, so if we travelled from earth at the speed of light, 186.000 miles per hour, it would take us 100.000 years to reach the end of our galaxy.




WELL, THATs REALLY ALL I CAN TYPE OUT RIGHT NOW, I KNOW A LOT MORE, BUT I DONT REALLY HAVE THE TIME TO TYPE IT ALL OUT.

TELL ME WHAT YOU THINK OF MY KNOWLEDGE.
YES I NO I SHOULDNT OF INCLUDED PLUTO AS A PLANET, BUT I CANT TRAIN MY SELF TO THINK IT IS NOT ONE.
AND AS FOR TRAVELING TO THE ENG OF THE MILKY WAY, I MEANT FROM ONE END TO THE OTHER.
I DID NOT COPY OR PASTE ANY OF THIS, this is what you get in return for spending a moment to ask the public for there advice, none of this was copy, it was all done NEAT so it could be viewd properly.

I didnt spend a full hours useing ( and and full stops for just the sake for doing it.
 
You might want to learn about the orbits of the planets and how to find them in the sky.

For example you said Mars is 38,000,000 Miles from Earth. That isn't usually true. That is the closest Mars can be to Earth, when both planets are on the same side of the Sun. When the two planets are on opposite sides of the Sun then they are 224,000,000 miles apart. The important number is the distance from the Sun.

And since most amateur astronomers are looking that the planets with their own telescope you need to know how to find them in the sky. That means you need to recognize the constellations and know how the planets move through them as they orbit the Sun at different speeds.
 
Here's a great fact sheet for the solar system. It lists the Dwarf Planets, too! Did you know that there are five?

Distance to planets from Earth varies widely, depending on their relative position in orbit. The inner planets are rocky midgets. The four outer (Jovian) planets are gas giants. Of the Dwarf Planets, Ceres is a rocky asteroid, but it is round, so it has been classified as a dwarf planet. Pluto is an ice world. Eris and Make Make are likely ice worlds, and Haumea displays characteristics of something more massive than ice and dust because it is oblate-shaped, but this is caused mainly because it is spinning rapidly. It's "day" is less than four hours. There may be more dwarf planets added as we get more information about other objects in the solar system.

You have made a reasonably good start. There seem to be a lot of question marks that could easily be replaced by other figures. I would, however, take slight issue with your statements regarding the speed of light and the time to travel across the galaxy. The speed of light is 186,000 miles per second, not miles per hour. And if you were traveling at that speed, which you cannot do, you would cross the galaxy in no time at all as measured by you, and 100,000 years (approximately) as measured by someone who remained on Earth. This is how time and space work as described by Dr Einstein.

In practical terms, it would take a significant amount of time to accelerate or decelerate a spacecraft to near light speeds, assuming we develop a technology to do that (which is difficult, but not impossible). Once you reach those speeds, you could cross the galaxy in a few years, again as measured by you. Once you account for the acceleration and deceleration times, you would probably experience several hundred years during the journey. In the meantime, the Earth would experience several million years, and would be in an entirely different location around the galaxy upon your return.
 
you obviously don't even have a notion of why the distance to earth from a planet can't be a fixed one .. hence I would say that you don't even know what you are copying

keep trying though .. astronomy is fascinating
 
An armature is the thing in the middle of an electric motor, or the thing on the end of an electrical relay

Perhaps you mean amateur

Your knowledge is interesting but you should be able to get the distance from the sun to each of the planets fairly easily
This distance is very important. The distance from earth to any of the other planets is not important
What about our moon? It is REALLY important to us as it creates our tides
 
Next, I would concentrate on my spelling if I were you.

And it is not YOUR knowledge if you just copy and paste. Believe me, it is obvious that this is what you have done.


Edit: Actually I apologise for being such a cynic. You have obviously worked hard and rightly take pride in your efforts.

To echo the comments of some of the other repliers: Knowledge is not just being able to list facts. Its the understanding of what it all means that counts.

For example: Have you thought about why some planets are rocky and some are made up of gas? Note how far from the sun each kind is. Now, why should that be?
 
a shopping list of facts (some wrong, some outdated). most are at an elementary school level. so what?

it's the application of those facts that makes the difference.
