a true time portal,did I ever tell you?
Posted by: pilotwingz on Nov-10-13 12:47 AM (EST)
...... when we look into outer space , especially deep space where things are millions to hundreds of millions of "light years" away .
Take for instance M104 (the Sombrero Galaxy) , it's 30 million light years away from us . Wait , what did I just say ??
Let me put it another way . The images we can see of M104 are it's light images that began their travel towards our eyballs in the Hubble camera ... 30 million years ago . Yes , give or take a few million , by the time we see that image of M104 it's 30 million years old ... we are looking through a time portal brought to us at the speed of light .
Wow , I used to think light was fast at 186,000 miles per second , but it sure takes it's good ol time covering 30 million light years of distance .
Even when you look up at the Sun , the image you see is already about 8.33 minutes old ... and the Sun is only about 93 million miles away (1 A.U.) .

..... or at least what it looked like about 30 million years ago , but I'm doubtful it's changed much since then ...

really beautiful. difficult concept to wrap a brain around. I guess we are "time travelers" when we look at the stars etc. it's cool to know I can see 30 million light years away.

Are meteors burning up in our atmosphere, so they are real time. You're seeing it as it happens. Something to think about when you do see one, consider that rock has been orbiting around our sun since the creation of the universe, until the dance of the cosmos causes it to enter the atmosphere and cease to exist in one brief flash of light.

The reverse is true as well|

Here on earth we have been broadcasting electromagnetic radiation into space for some time now. Could first impressions of us to another civilization be Lucy shows?
then there's the time it takes|

For the information to get through the cornea and pupil, past various synapses into your brian where sense is made of the info.

.... don't know how to compute that time because my brains ahead of me ... I'm just following along :-)
I know I've heard synapse speed|
Posted by: slushpaddler on Nov-11-13 3:26 PM (EST)
...but I don't remember it. Probably because it's somehow not as impressive as the time it takes light to travel across millions of miles.

The M104 is the Manhattan crosstown bus.
it's flat and there are tortoses on it|

Or maybe it was under it... I forget. Anyway, I don't buy all that stuff about million years. You ain't been there and have not seen dinasaurs. In fact you put it the moose bones in there and pretend they are dinasaurs... I'm just going to put fingers in my ears and go blah-blah-blah-blah!

Makes you laugh when in Star Wars they would Jump to Light Speed. Now it would only take them a few thousand years to reach the Andar plant. LOL

Just remember that you're standing on a planet that's evolving
does the 39th revolve slower ??|
Posted by: pilotwingz on Nov-12-13 11:00 PM (EST)
.... I get the 900 mph. (think it's a little more than that though) ... but that would be at the Equator , right ??
A little over 1000mph at the equator|
Posted by: pirateoverforty on Nov-12-13 11:41 PM (EST)
This sight has a formula for calculating speed elsewhere. The center of the US is probably 900MPH
yeah that's the way I thought it worked |
Posted by: pilotwingz on Nov-13-13 3:03 PM (EST)
....... your linked site "about.com" shows 794 mph on the 40th .
The earth is not round|
Posted by: pirateoverforty on Nov-13-13 5:05 PM (EST)
It bulges out At the equator due to centrifugal force. Gravity is a result of the mass beneath your feet. Less mass at the polls between the surface and the center of the earth and less centrifugal force, at the equator more of both. The earth's shape is defined by the point where centrifugal force nulls the gravitational forces. So since the attraction to the earth is perfectly counterbalanced to the force trying to throw you off at all points on the surface, I would have to say, I'm not sure.

That is the Sun were to instantly vanish, now! we wouldn't notice for 8 1/2 minutes!
well , if it happened at night time ....|
Posted by: pilotwingz on Nov-26-13 10:45 PM (EST)
..... it might take a bit longer to notice :-)
