While in my opinion, there is enough independent evidence to cautiously suggest that global warming (which itself is not in dispute in scientific circles) is more likely to make bush fires worse than better
Why? Climate Change does not automatically make every area more prone to the kinds of disasters that frequently occur there. Why wouldn't it lessen the chance for severe wild fires? This is the kind of thinking that fuels "deniers". It's always, smaller polar caps, retreating glaciers, intensified tornadoes, wildfires, hurricanes, rising sea levels. Why not more rain in the desert or semi-arid farmland? Or the shifting of severe weather events to another area? More snow for the ski areas. Less rain for flood prone areas. Why is it always worse?
A liberal administration isnt going to crack down on porn; it would alienate huge parts of their base.
You mean like how the DEA is still going after medical marijuana dispensaries in Denver despite Obama supporting legalization? http://www.denverpost.com/news...
Even if we solve the propulsion problem, there's another problem--uncharted objects like this.
If we could actually speed a ship up to anywhere near the speed of light, even hitting a pebble is likely to blow up your spaceship.
But how do you explain why we don't detect these hundreds of objects in front of other stars?
You're assuming these transits would occur frequently and that we actually have the equipment pointed at the sky to detect them. Even if there were 200 times as many brown dwarfs as stars in the galaxy, actually seeing one pass in front of another star would be an extremely rare occurrence and we'd only detect if we were looking right at that star. Even then we'd only detect a small decrease in light and we'd be unable to distinguish it from the transit of a planet with a long orbital period. Also, consider the velocity of stars in relation to each other? The transit may only visible for a fraction of a second...in which case we wouldn't be able to detect it at all.
These aren't small things, and we can detect wayward exoplanets
Brown dwarfs are small. And we can only detect exoplanets by detecting the effect they have on the wobble of the host star, by their transit of the star, or very rarely we can see light from extremely hot planets.
How come they don't collide? Why didn't they collapse into just being, you know, stars?
Even at 200 times, collisions would be extremely rare. And the collision would be a non-event as far as the earth is concerned. Why don't they collapse into stars [assuming the collision produced a star with sufficient mass to be a star]. Maybe they are? Still the collisions would be so rare that we'd almost certainly never witness the event.
if there's so many how come they haven't been turning up at a clipping rate?
The only part of your argument that really works. Even with the limited instruments we have now, we'd expect to see more if there were 200 times as many brown dwarfs. But then, we're discovering a lot more of these now that we have instruments designed to find them. Regardless, I don't think 200 times the number would account for the missing mass.
Going the speed of light is bad for your age.
