The article is from yesterday, so tommorow is today.
Yesterday you said tomorrow
When will then become now?
1.3ms sooner than we expected
Wait, I'm in Australia, does that mean I missed out already on the second point thirty thing?
Didn't happen in Australia. There's way too many spiders and brown snakes.
And today is yesterday.... you heard me.
I'm going to leave work 1.3ms early
Pft. Rookie numbers. I've been leaving work 1-4 hours early as meetings allow.
Just to avoid confusion for others that havent read the article. That's the reason the rotation has been slowing down for quite some time.
The reason it's spinning faster now is speculation for now and might be because of a shift in the earth's core, melting ice, earthquakes or some other causes.
Predicted but not explained, what?
And yeah, moon farthest away, thought so.
Are we going to fall off?
Not unless you're at the front.
Phew
I wonder if you could tell by measuring g today
I mean, I know you theoretically could, but would it be a "noticeable" difference? Like to the second or third decimal?
If my math is right...it will have an effect of approximately 0.0000000001 g
Angular acceleration is r*w^2, so for a normal day that would be 6371000*(2*pi/86400)^2/g = 0.0034345580g
On this accelerated day, it becomes 6371000*(2*pi/86399.9987)^2/g = 0.0034345581g
That's at the equator assuming a radius of 6371 km, which is a decent ballpark, the specific number won't change the result much.
Pretty sure I won’t notice, but I appreciate the cool photo
