Is hazardous waste a national problem or an international problem? Explain your response. Many ecologists would like to move away from protecting individual endangered species to concentrate on protecting whole communities or ecosystems. Others fear that the public will only respond to and support glamorous “flagship” species such as gorillas, tigers, or otters. If you were designing conservation strategy, where would you put your emphasis?

The earth and other planets where formed from leftover matter stuck in our suns orbit. I'm just wondering if having an earth twice the size as ours now would be more beneficial to the complexity of life or worse? Like the more diversity there is the higher the complexity can get so earths wide diversity plays a huge roll in how we got to where we are now so what we could do with a planet twice as large would be astonishing if we could adapt to the extra gravity. If we where going to look for other life on different planets what stars would be the best to look at? Our sun is perfect for our planet but would a bigger sun possibly with the right conditions possibly host an even more complex life form? Because if are sun caught this much matter in it's orbit then an even bigger sun definitely would have caught more matter. Any thoughts about this topic right or wrong would help thanks?

Puzzling thing that all matter isn't in a sphere around an empty origin where all matter was made, I mean if their was 1 big creation of matter then it would be in a clump right and if this energy that's moving it apart separated this matter it would move in clumps kind away from this origin but would move in every direction away from this spot and would leave a place with no matter is left. So how do we have evenly distributed matter across the universe? I don't know but maybe all the matter wasn't created all in one bang it's pretty easy to suggest this it gives you an easy thing to work with in a sense but not a really plausible idea this could have built up gradually.

What's the definition for nothing. Wouldn't it be a space with absolutely nothing that we detect, this nothingness would have no time or deception or direction about what's happening to this empty space because theres nothing in the end to truly detect. Now what happens if a huge static discharge at the hugest scale in this nothingness and now suddenly what had no shape, boundaries, corners, deception of here or there finally come into play? I can tell how far I am from something because I exist in something. When light travels through space it still takes the sun 8 minutes for light to reach earth so that light if it went through nothing should have been instantaneous their for to have time reference their needs to be something.

Can light dissipate? Like eventually fade out into nothing? because as far as I know we get light from across our universe and it's still traveling the speed of light so would it ever really stop? Which leads me to think we are definitely moving into a vast empty space since that light that stars give off is sent deep into space deeper then any matter we know of an what happens to it? It doesnt get bounced back at us or space wouldnt be black we would have a definitive end to all this so it's getting absorbed into something or turned into something.could possibly be one contribution to dark energy like say any wasted energy in are universe isn't truly wasted just collected far out into space and basically in a sense recycled.

So if the universe is not going to pull itself in and it's speed of exspansion is increasing then your not looking at a big bang at all, theirs some other force pushing or pulling it from itself. Then could we predict this is the first time this has happend and there was nothing else like it before?

So I concluded that energy can't be distroyed or used up only converted or changed into a different type of energy sound, light, heat, and motion. If I swung a baceball bat in space and hit a ball with it would it make a sound? if not that's probably because theirs nothing to resist the ball from moving so theirs no chance to convert any of that energy into sound only motion. Any tips for this?

This is just a thought but what if we thought of the universe as a big gym just it's endless.. Now if we started with a collection of matter that built up due to gravity and started the big bang that sent matter in all direction from the middle of the gym and say the basket ball hoops are pockets of dark matter that we cant see and some of that matter flys through it collecting some of it and then eventually bringing itself back into itself like a big crunch this time with more energy from what it gatherd. Then something happens when that black hole all came together and it exploded again sending matter in all directions again but this time sending it a little bit furthure because of that extra energy so in turn it would pick up more of that energy because instead of just reaching the basket ball hoops it makes it to out side the gym doors creating a chain reaction that makes the universe a never ending cycle.. I don't know what we classify the universe as if its everything we know of but the thing we are moving into has to be so much more vast that we can't even fathum the thought of everything we know of in a bigger container. I believe that "container" would have had to be their so already so it's not doing anything we are just geting lager in it.

Just like a second dimentional living thing can't imagin a world in 3rd dimention because it's simply not part of it's world. If we think of the univers maby that's the 3rd dimention the one we live in and the fourth one is what we are moving into. How can we fathom the thought of what we make up? It's like standing on the ground and trying the make out a crop circle when someone from a plane can easily make it out. The univers is are world and all we can see but something holding the univers I mean it can't be just floating out of no where but we can't see it because it's so much for us from where we stand to understand it.

I'm just running on a thought but if matter can't be distroyed maby same with energy. Dosent matter what you do it will just be transfered or changed into another form of energy sound heat ect. or even something els we can't sense. When an atom is split it gives off so much energy it probaby took that same amout of energy to put that atom together at one time. Now no ones ever told me what protons and nutrons do but if theres that energy in that stable structure those protons and nutrons could be doing some function in a way kinda like a plant or animal cell and as a reaction to this it gives you gravity. If you can help me to understand this if I'm completly off that would be great thanks

This question has been trubling me for along time. Do we have any facts supporting the idea that light is a wave or a ray because I really have a hard time understanding how light can hit every spot on an object and fill in the gaps of every spot that isnt in the direct line of the source of light. If a star millions of light years away that are giving of light rays those rays over that distance would almost practicly miss earth. Wouldnt it me more beleavable to call it a type of emershion of energy almost like water that just filling in all the gaps?

Can energy be destroyed? Because if not it can only be transferd from one thing to something else or it can create something. Could it be fair to predict that the same amout of energy that is giving off when you split an atom could be similar to the amount that was probably needed to put it together at one time?

When a star is dying it burns up the last of the last of the matter that's sustaining it so it colapses into itself exploding into whatever you want to call it depending on the size of the star right? And I'm guessing since a black hole has a greater gravitational pull then a star it has more matter in it just we can't see it because everything that goes into it dosent come out even light right? So my question for you is if everyones going with the big bang theory what caused the bang because as far as I know since the most matter in one place that we know of becomes a black hole then wouldnt the big bang theory be one huge Black hole? Just a guess but if you had that super massive black hole and it really sucked in everything into it matter and space and it had nothing else to pull in that gravitational force could somehow reverse itself. Sorry for the question I'm 16 and really have alot on my mind if you could clear things up for me that would be great thanks.

If space is a vaccum it's not going to have any resistence to stoping all the matter from the big bang but what if some how they where linked to each other by gravity that will in the future it will pull itself back into itself crunching itself into a masive black hole doing crazy stuff!
