Well, it's official now.
Scientists have determined that an asteroid did in fact kill the dinosaurs.

Read about it here.

The link's broken.

Without having looked at it, I got to say I'm a bit skeptical. My Christian worldview aside, even if we know that they died 65 million years ago, I've very skeptical that somebody can say for a fact that an asteroid killed them. Heck, there could have been a worldwide reptile virus that killed off the dinosaurs, and an asteroid just happened to hit the planet around the same time.

Just my quick two cents anyways.

What about Quasars? Many scientists believe they are black holes or white hole.

[Siguy]

Quasars almost certainly involve supermassive black holes, white holes are purely hypothetical and could not produce high energy cosmic rays in the same way that quasars do.

Also, I LOL'd at your signature.

So quasars are only supermassive black holes?

(I think I know why you LOL'd at my signature )

I was looking into it and most of the people in science say that alignment will occur and isn't the first time it has occurred either.
I thought they had said it happened some time in the 90's?

I thought the claim was that the earth and sun will align with the center of the galaxy. In that case, it happens every year. In the case where all the planets align, this will not happen again for decades to come.

Well, it's official now.

Yeah, though it has petty much been consensus for decades now. However there is also a newer theory that disease was involved in the extinction of the dinosaurs! Check out this clip from Nova Science Now.

Well, basically yes. Quasars are powered by supermassive black holes.

I just wanted to realise something.

I really want to know if there are more than 3 kinds of nebulae.
(The 3 I know are: Emission, Planetary and Bok Globule)

Wrap your heads around this one. (LINK)
What do you all think?

I actually think that if we discovered life today, it would be far more shocking to our culture than if we had discovered it say, 50 years ago or before that. For example, in the 30s it was almost universally accepted that Mars could still harbor life, and even the skeptics said there could be mosses or lichens, and that wasn't a big deal at all. Nowadays it would be considered the most important scientific discovery of all time if we found even fossilized bacteria on Mars, and few seriously believe that to be a possibility. We've certainly changed our expectations.

Also, 2000th post. Weee!

Wow I haven't posted in a long time on this thread but I found out they found an ape-like creature on Mars. Is that true?

That would be totally false.
Where did you hear that?

Hey Rocksfan, I wanted to add something to the discussion on laser guns, from way back in 2008.

It is true that the most powerful rays would probably exist beyond the visible spectrum, yes. However a standard "pulse" laser device is more than powerful enough to put a hole through metal with a bright flash.

In addition, while there'd be no light to "see" (aside from a brief spot on the target and probably either a small "click" or a loud "bang"), with these types of lasers, upon firing, a breakdown in the air can cause th travelling ball of plasma to be filmed in freeze-frame, much like a bullet leaving a gun. I very strongly doubt you can see this ball of energy with the naked eye (especially when pulse lasers only have so much range) but the fact that this can be done may come as an interesting surprise: A bullet of energy that travels slow enough to catch it on film.

It kinda looks like one of Megaman's buster shots. XD

I would truely like to see said film.

A real life laser/phaser in action, caught on film.

Still proving quite difficult to evade. On that subject though, I am quite interested in the reason why we as a race have not developed particle weapons yet.
The technology is obviously there, so where the hell are they?

[NoeL]

It's not like we NEED any more weapons.

EDIT by ShadowTiger: Fixed YouTube tag. .. Yay.

This is a pulse laser fitted into a fancy, Sci-fi gun form,with portable power. It can fire six shots before it needs recharging, which, frankly, even given the tiny range of about 1-2 feet, is still an impressive amount of shots.
