Likely the best you can do for those is to have them 45 deg away from the case and angled so that they are 90 deg from each other. That is, they form an off-axis "V" shape.

Happy fast crunchin'!

That is a very true bit of knowledge. I'm impressed when anyone knows that.

Interesting, Lynn:)

Yes it is interesting, Julie, hope it stays 26,000 light-years away from earth.

I am really enjoying the great links, and raw science. We may eventually end up with a Black Holes part 3. :D

Does anyone know how wide the universe is? The most accurate age estimate I have heard is 13.75 billion years, so that would be 27.5 billion light years in diameter. How much is space expansion, and how much is what we would expect?

Have you tried increasing the voltage? I have the voltage on my cards maxed out at 1.138 VDC. Some cards may need more voltage to just do stock speeds, at the intensity we drive them. I believe the 590's are intentionally undervolted, because the 580's didn't like higher voltage, but I could be wrong about that. I haven't checked for quite a while.

I can get downclocks if I push the overclock on one of my cards too much. Now that I know the new operating point, it is fine. I have one running at 871 MHz, and the other running at 857 MHz. Stock is 700 MHz. All voltages are at max, and temps stay below 60°C.

Steve

Edit: Sometimes I can get a downclock from running Einstein, but that seems to be code related. Seti is totally stable.

I make up my mind all the time, and change it when warranted. What leads me to my decisions is evidence. I have no problem at all admitting that something I said was completely wrong, provided I have solid evidence to the contrary.

As for the ET conspiracy, I think the story is much more interesting that the factual information. Even if we were to have ET visitors, I would need to get past the physics of traveling what is certainly more than 100 light years, at speeds that are locked at a maximum of 186,000 miles per second, and dealing with time dilation, and the deaths of anyone left on the "home" planet by the time any visitor returned. The only way, given the huge distances that makes sense, is to have several generations embark on the trip, and several generations on the return trip. That doesn't make sense with them staying a short while, leave no concrete evidence, then heading back. It would be a bit more like this link.

http://www.cnn.com/2013/04/22/world/mars-one-way-ticket/index.html?hpt=hp_t3

The distances are just to huge. Even if I see something myself, I can't explain the physics, so I would be more inclined to come up with an explanation that fit the physics.

I also think there must be things the governments won't tell us and I think their main reason is to avoid a panic outbreak...

I don't think that any government anywhere has any alien spaceships. But I do think it is possible that the USA at least, and possibly the UK also, has some sort of evidence that ET does exist. But for the sake of avoiding mass panic, and civil unrest throughout the world, they are keeping it back. And rightly too.

If the world can't keep nuclear secrets secret which can be an immediate and severe threat, then why would they be able to keep alien secrets secret, when thousands of people must be involved, and any actual threat is minimal?

I would be panicking a lot more if some rogue country launched a few nuclear tipped missiles than I would at confirming evidence of ET visitation.

Steve

Edit: I can add that scientist have alerted all of us that there are extinction events that can do a lot of harm, very quickly. Super volcanoes, gamma ray bursts within 2000 light years, meteor impacts, plaques, hurricanes, tornadoes, earthquakes, floods, fires, and of course wars. The only way they could keep a secret like ET visitation, is if there was no secret to keep. Panic the world with concrete news of ET, I just don't see it.

never understood why they never sent some new 'Voyagers with todays technologies' towards our neighbors yet. i m pretty sure they would be already further than the old ones.

Mostly we are stuck with chemical rockets, and speeds similar to what the Voyagers are doing, and Glenn is somewhat correct. We did use gravity boost, but with specific trajectories to get them heading out of the solar system.

Even at extreme energy levels, whether it is the formation or feeding of black holes, or the results of the extreme collisions of particle accelerators, there is no evidence that something could travel faster than light. One of the more promising long term solutions is
Ion Drive. Even that has it's limits due to the very low thrust.

With such puny thrust, a NEXT-based ion drive would need to run for 10,000 hours — just over a year — to reach a suitable speed for space travel. Dawn, a NASA probe that’s powered by previous-generation NSTAR ion thrusters, accelerated from 0 to 60 mph in four days. As a corollary, ion thrusters only work at all because of the near-vacuum of space; if there was any friction at all, like here on Earth, an ion drive would be useless. The good news, though, is that the (eventual) max speed of a spacecraft propelled by an ion drive is in the region of 200,000 miles per hour (321,000 kph).

The efficiency is really much better than chemical rockets, but even at maximum speed, it is not even close to light speed.

The fact that scriptures and the Bible came up with nothing relating to modern science or for that matter current society should tell you exactly what is worth.

RELIGION has killed more people than other men intended.

I remember saying exactly that here 5 years ago, when I got roundly castigated by everyone.

And rightly so, trying to blame violence and death solely on religion, when we know the USSR had no religion. Such a statement seems to be about as silly as saying that atheism has killed millions in the 20th century. Both simplistic views.

Trying to forget all the massive killing done in the name of the lord huh?

1) The crusades.
2) The inquisition.
3) The killing of the Native Americans.
need I go on?

Here is a link with some more information. There is a good post in this link that describes wars done for religion, and not for religion, but I wanted to include the whole link.

I have seen information that says that the percentage of mentally unhealthy people is pretty much the same from country to country. I have seen information that many countries play violent video games, but that is pretty much equal also. We are all humans, and have basically similar genetics. There are acceptations, where people living in high altitudes have bigger hearts and lungs, or people living in different environments have adapted to the different conditions. But, over all, people are very similar. Laws don't always work, sometimes they do, but the availability of firearms does change the outcome. If a country has the most guns per capita, then the most crimes by those guns is at a higher level. That doesn't say that law abiding gun owners commit crimes. They don't.

Here is an easy idea.
If we know the exact distance between any two points on one side of the earth, and pick a galaxy to pin point. Measure the exact angle from each point to that galaxy, and by simple triangulation, you will get the distance to that galaxy. Since the light from those galaxies travels at a constant rate, it becomes simple math to calculate how far away that galaxy is. If it is older than 6000 years.... then the universe must be older than that. If the universe is really 13.75 billion years old, then what sense does it make to say the earth is only 6000 years old, when we can see various solar systems in different stages of development, and see what it takes to build a planetary system.

That doesn't even include red shifts, just simple triangulation.

Steve

Universe = 13.75 billion years old, created in 7 days.... Really?????
That seems a bit of a stretch to me.
