no more at risk than if it was going at 10000mph.

large objects are (counter-intuitively) not the largest hazard. they can be easily seen and a small burst from the attitude control thrusters(or manouvering thrusters) would be sufficient to avoid them.

The big problems with near luminal travel come from dust. you won't see the dust and if you go fast enough each grain will be as destructive as a hiroshima bomb. of course, if you've managed to get the technology to get up to those speeds then you're likely going to be able to have a lser or something to nudge them out of your way.

If you were to look up at the moon and observe the flash of light caused by a meteorite striking the surface, it actually happened a whole second before you saw the light.

the CMB was emitter a long time ago true, but it was also emitted ~13.7 billion years ago.

if you would call seeing the flash of light on the moon a direct observation then picking up the CMB on your TV and radio must also be a direct observation.

SOMETHING emitted it and that something must also have emitted it from every point in the universe at the exact same time. there aren't many ways to do that. one of the simpler ways to explain it is if all the points in the universe were the same point at time zero. or at least very close to it.

just because the light has travelled so far doesn't mean we are observing fictional light.

surely you could just make a factorial function for your C64, right?

thats the beauty of programming, if there isn't a function for it, just program one! computers are turing machines so they can perform any process (at more or less efficiency than others)

if you really really wanted to you could run global weather simulations on a C64. they'd be so slow as to be useless and the hardware would probably fail before the second iteration completed but you could get the exact same results as the super computers they run it on.

because marriage is not monopolised by christianity.

also, you have a little thing called separation of church and state. the opinions he expresses as president may not be the same as his own personal opinions.

of course, he could also be displaying that christian trait that is prized above all others: tolerance.

is this what you mean?

I've used this to determine hygrocopicity at my work many times (with a few modifications so it reflected the working conditions rather than the lab setup.)

If it isn't then you'll have to explain, because thats the closest thing to an index that i can find or have heard of.
