Interesting Fun Fact !

NASA has been setting the clocks on everything they send into orbit not to earth time.
But to to their orbit times.

A related fun fact! Without planning for time dilation, GPS would not work. GPS and Relativity

The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)! This sounds small, but the high-precision required of the GPS system requires nanosecond accuracy, and 38 microseconds is 38,000 nanoseconds. If these effects were not properly taken into account, a navigational fix based on the GPS constellation would be false after only 2 minutes, and errors in global positions would continue to accumulate at a rate of about 10 kilometers each day! The whole system would be utterly worthless for navigation in a very short time. This kind of accumulated error is akin to measuring my location while standing on my front porch in Columbus, Ohio one day, and then making the same measurement a week later and having my GPS receiver tell me that my porch and I are currently about 5000 meters in the air somewhere over Detroit.
The engineers who designed the GPS system included these relativistic effects when they designed and deployed the system. For example, to counteract the General Relativistic effect once on orbit, they slowed down the ticking frequency of the atomic clocks before they were launched so that once they were in their proper orbit stations their clocks would appear to tick at the correct rate as compared to the reference atomic clocks at the GPS ground stations. Further, each GPS receiver has built into it a microcomputer that (among other things) performs the necessary relativistic calculations when determining the user's location.
Relativity is not just some abstract mathematical theory: understanding it is absolutely essential for our global navigation system to work properly!

Then you have a huge argument with accepted science.

Hardly, read the link on EPR and quantum entanglement.

That term is not comprehensiv enough.

Oh, also, poor Michio Kaku.... doesn't even place over Bill Nye. :2razz:

Well Billy Nye IS the science guy, so that's hard to beat.

I listened to two episodes yesterday while working. Tyson does a great job explaining complex subjects. I imagine that's what bugs the simpletons.

You watched Cosmos while working? Are they looking for applicants at your job?

In theory, an object without mass can
travel faster than light. At least, I do not know of any proof saying it cannot.

Thats a interesting article. Thanks for posting it.

No, that is part of accepted science.

Can't have it both ways Red.
In one post you said it can't be done and in another you say it can.
Don't go all squishy on me.

Do you have a double degree in a science-based profession like engineering?

Good stuff.
My comment to you was tongue-in-cheek.
Given what has been declared to be a law of physics, it's things like that make me, at least, recoil a bit at the noted certitude of "settled" science or settled anything else really.

Creationist can mean two very different kinds of people who believe in magic - the people who believe some magic was farted down from the sky and created man 6,000 years ago or it can mean that some people believe that there is no genetic basis to race because evolution was magically stopped somehow 50,000 years ago. Both believe in magic but they point to different magical stories, hence Liberal Creationism is different from Religious Creationism.

I had never heard of a "liberal creationist" until you just made it up...nor have I ever heard of ANYONE claiming race has no genetic variable.

By the way....50,000 yrs. ago there were already races of human.

Reading comprehension is so hard...

Let's look at what I really said:

Mass increases as you approach the speed of light.

Now tell me how that is saying that "quantum entanglement" can't be done?

When you replied "Mass increases as you approach the speed of light." , what question was it a reply to?

Probably means you definitely can't listen to Cosmos while working

I'm listening to episode 6 right now. That's the one about light. In the episode, Neil does a hell of a job pointing out how science means not blindly following what is written in ancient books or what you are told by your elders, but rather to be sure to question, experiment, observe and then correct false assumptions.

I wonder who that would offend?

I am sorry my comments went so far over your head, really I am. Let me hold your hand a little bit: Increased mass makes it harder to accelerate towards the speed of light. Now read about "quantum entanglements" and see if you can figure out what has to be accelerated.

Oh my ... don't you ever get all huffy when someone points something out to you.
But that's okay ... you can't help it ... it's that whole ego-gratification thing of yours.
Keep your fingers crossed but maybe only you & I noticed that your recovery attempt failed.

Yeah he can...it works for sure if whatever entangles those electrons is massless. Objects with no mass can travel infinitely fast. Photons are limited in speed by their mass, as little as that is. Anything lighter than a photon can travel faster than one.

Nevertheless, neutrinos do have mass ... extremely negligible, but they have it.

I do not think that we've found anything which is without mass, neutrinos included. I have not read anything which suggests there is proof that a neutrino travels faster than light.

I suspect that a lot of things we do not yet know about do however travel at superluminous speeds. It makes sense. After all, we find things we never knew about all the time. And, if you think about it, something must explain entanglement.

Re: Neil de Grasse Tyson Smacks Down Creationists Who Are Demanding Equal Time on Cos

I finally listened to all 7 episodes of the show. And--this is even though I agree with Neil--I can see why the fanatics hate the show. However--and this is important--would you really tell your child that Neil is wrong, that your silly superstitions are more important to adhere to than learning real science, which today gives your kid a decent chance to earn a nice living if not actually become somebody--you know--like one of the great discoverers Neil talks about?

Disclaimer--I am a "scientist", someone who makes a pretty decent living dealing in things which are real.

I see in checking sources that some web pages are using the tag, "Neil de Grasse Tyson's Cosmos". Neil de Grasse Tyson didn't have anything to do with the creation of the Cosmos series. He's a PRESENTER of the REMAKE of Carl Sagan's famous TV series and book. Carl Sagan wrote the works. Let’s give proper credit where credit is due. As to "creationism", what does that mean exactly? Cosmologists, the vast majority of them, support the Big Bang Theory. I believe it too. There are just too many mathematical models that support it.

Yet the most bizarre aspect of the Big Bang Theory we have to wrap our minds around is the fact that everything in our universe sprang from a concentrated blob of matter no bigger than the nail on your little finger. If that wasn't an act of creation, then what was it? An act of recreation? Perhaps. Maybe it was a collapsed former universe recreating itself. Maybe that death and rebirth cycle has gone on for eternity. Who knows? Neal de Grasse Tyson certainly doesn't. Nor did Einstein. He professed to be an atheist most of his life, yet even he struggled at times trying to reconcile the creation of everything from nothing...without, well, you know...God.

It's hard to call the current edition of Cosmos a "remake." This is not like they when rebooted Spider-Man. The Tyson version is a vehicle to bring science to the masses, much like Sagan's, but calling it a "remake" is a stretch.

Well that explains it then. I made the observation that it didn't really contain enough 'hard core' science facts, as in not enough of them, because it does have them.

Your post there, 'bringing science to the masses' is the first time that I've read assessment or goal, and I think it's accurate. So, no wonder, that a hard core documentary / history fan like myself feels that it's a bit 'lighter' than what I'm used to. But that's OK. I like Tyson as a presenter, and the program is interesting.

"Your Inner Fish" is another good one. All about human evolution, and vestiges of evidence within our own bodies of the evolution form whence we sprang.
