[QUOTE=UserDerth;20510611]Wait 10-4 = 10 to 4 years? D:[/QUOTE] E means x 10 to the power of... I.E: 5E-2 =5 x 10^-2 = 0.02 you do this shit in grade 8, right?
The day becomes 22 ms longer every 100 years. That means the dinos had a day which was an hour shorter, and Cambrian animals would've had 20-21 (Cambrian was long) hour long days. [url]http://en.wikipedia.org/wiki/Tidal_acceleration[/url]
So [i]this[/i] is why my PlayStation 3 thinks its 1999.
[QUOTE=UserDerth;20510611]Wait 10-4 = 10 to 4 years? D:[/QUOTE] Standard form, learn it.
The guy who works in Grenwich will now have to do some math.
It's just like when in 2005 or something, at New Years the year became 30 seconds shorter. Everyone was going bananas about it...
[QUOTE=CivilProtection;20510506]that's barely anything[/QUOTE] An earthquake moved the Earth on its axis. It's a big deal.
Oh, is this why the PS3 internal Clock got buggered?
ALL earthquakes fasten (it can also slow it in cases) down the Earth, it's just that when a world-wide known earthquake happens journalists try to get another article on their name, so they write about this.
[QUOTE=Killuah;20510651]No. That's against the law of constant impulse.[/QUOTE] You mean momentum (the translation of the German "Impuls" is momentum - I know, strange how they use momentum). And it'll be possible, if he'd release an enormous amount of poop-gases. But don't ask me how much billion tons of Methane he needs to exhaust in a second.
When I read the thread title I thought it meant as in the world is going to end sooner.
[QUOTE=Doug52392;20511838]So [i]this[/i] is why my PlayStation 3 thinks its 1999.[/QUOTE] The onboard seismometer on the 60GB models wasn't calibrated properly. They installed a more accurate one in the slims. [editline]12:47PM[/editline] It really does do everything
So when I heard about this, I thought about thatthread about the gigantic meteor that passes earth every few years or whatever and how it's inches away from hitting us. Does this mean there is a greater chance of it hitting us now or am I being extremly paranoid?
[QUOTE=rieda1589;20510618]Scientific notation. It's the same as saying 5.7E-4 If you haven't come across it yet, you will if you do any kind of science involving big/small numbers. Basically it's easier to write 5.7E-4 instead of 0.00057[/QUOTE] Also known as standard form in maths. But it would be 5.7×10 to the power of -4 (don't know how to show powers properly on a computer).
Am I the only one who thinks days have been going longer since the earthquake?
[QUOTE=Asaratha;20515226]God damnit chile. you bastards[/QUOTE] Yep, thank you, like we wanted it happened... ¬¬
[QUOTE=Omolong;20516053]Also known as standard form in maths. But it would be 5.7×10 to the power of -4 (don't know how to show powers properly on a computer).[/QUOTE] To do Standard Form properly on a Computer you do it like this: [code]5.7*10^-4[/code]

[QUOTE=CivilProtection;20510518]I meant 1.25 microseconds is barely anything[/QUOTE] Yeah, but in the grand scheme of things. 1,000,000 million years down the line things could be fucked.
[QUOTE]“The axis about which the Earth’s mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimeters or 3 inches).”[/QUOTE] I don't see how the Earth's axial tilt is relevant to the length of days nor how it's even possible for an earthquake to affect it.
That's actually quite fascinating.
How do they even calculate these things so accurately? [QUOTE=ThePuska;20518154]I don't see how the Earth's axial tilt is relevant to the length of days nor how it's even possible for an earthquake to affect it.[/QUOTE] Think about it, simply jumping on the moon will move it slightly out of its normal balance because of the force, albeit it'd hardly be anything at all. it'd still change it.
Didn't the exact same thing happen with that Indonesian earthquake some years back. The one that made the tsunami that killed hundreds of thousands of people? I'm sure I heard that.
