Stuff that 'boggles' your mind.

Where are we going? What will life be like in 1000 years? Stuff like that really ****es me off as I know I won't be around to see it happen

People then will probably be thinking the same thing, and people in the past probably thought it about our time. Would be nice to see things to come but our lifetime is literally the blink of an eye in the grand scheme of things

Dark matter is a type of matter hypothesized to account for a large part of the total mass in the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level.[1] Instead, its existence and properties are inferred from its gravitational effects on visible matter, radiation, and the large scale structure of the universe. Dark matter is estimated to constitute 84% of the matter in the universe and 23% of the mass-energy.

Cannot see or detect or explain it but its 84% of all matter.

Women who dress like total tarts on nights out with stupid high heels, skirts up their backside and boobs practically falling out of their tops and then they wonder what we men are looking at :eek:

There are theories which explain the gravitational workings of the universe which do not require dark matter. They just happen to suck at explaining many of the things that dark matter explains (although I believe MOND happens to be slightly better at explaining galaxy rotation curves). I've always thought of dark matter as a placeholder. It sits there to fill in the gap until we can directly test it and fill that gap in more rigorously.

One idea is that dark matter is made up of what are called Weakly Interacting Massive Particles (WIMPS for short). These could be the remnants of micro-black holes that have finished evaporating, leaving behind only the tiniest of particles. These particles would only interact with baryonic matter via the gravitational force and the weak nuclear force. Since they do not interact with the electromagnetic force, they cannot be detected visually. That makes them a right pain in the arse to detect, since light-based detection methods are what we as a species happen to be really good at.

Tried that and my computer caught fire :eek:

Lol hold no a sec i have only watched up season 6 on Voyager, they haven't dealt with Dark Matter yet, i would rather have there version of events

I hope to God you don't mean Star Trek Voyager.

Or you know, you could just read this.

Yes i do.
Where you think my first quote can from? Its the first sentence!

What boggles my mind is Oil, such a useful resource and what will we do without it?

Just can't imagine life being as convenient as it is now.

Ah yeah, that's another good one. Every time I have to throw away that plastic from food that's not recyclable, I just imagine it being incinerated and I think about how all the oil used to make it will be gone forever. Then I think, what will we package food in, and what will they used in hospitals for blood bags, syringes and whatnot when there is no oil to make plastic? Maybe they will make a good replacement from plants.

What happens when a fly is in the metro ? does it have to fly onwards ?

Are you being sarcastic there about oil formation, or did you genuinely not know where it came from?

Why my university doesn't offer a degree on Stargate SG-1. It'd be epic.

Does it matter?

The point about it 'running' out still stands.

Just thought of another one:

Just how much water is held up in the sky! I mean it's not exactly light stuff, 1 litre weighs approximately 1kg (ok i know it's not exact, don't go getting all scientific on me now).

And yet it can rain for hours at a time.

One sperm has 37.5MB of DNA information in it. That means a normal ejaculation represents a data transfer of 1587GB in about 3 seconds.

mind. blown.
