Astronomers Spot Planet Which Could Have Earth-Like Climate, Water On Surface
- "Faster-than-light" observations and experiments
The blue glow in this "swimming pool" nuclear reactor is Cherenkov radiation, emitted as a result of electrons travelling faster than the speed of light in water.

- Your clock example, could there be any outside factors that would result in the fraction of a second deference? The fact the 1 clock was in motion and the other was not? The fact the 2 clocks where in different places on the face of the earth?
Since they are atomic clocks, they are not affected by changes in motion or other outside factors. As I just mentioned, gravity can also affect time. But even cancelling out the gravitational force affects, the clocks still slow on the plane.

That's why guys like Einstein and Hawking are geniuses and we aren't :) But almost all of Enstein's work can be proved in the labratory. For instance, gravity can cause space to bend. This was proved during an eclipse in 1919 by comparing photographs of the star field around the eclipsed sun with photographs of the same stars when the Sun was not present. Scientists observed that the position of the stars appeared to have shifted when the Sun entered the equation. The gravity of the Sun, they concluded, was bending the light from these distant stars, thus proving Einstein%u2019s theory that celestial gravity %u201Cbends%u201D space. - Reply to this comment
- itwasntme,
that makes no sense. Age is a measure of time where 1 year equals 365 days. A lightyear is a factor of distance with time being a constant. Sounds like you are looking at a lightyear with distance as the constant and time the variable.
Thank you guys for trying but I guess I'm too hard headed.
You are trying to convince me that two babies born at the exact same time. They leave the hospital at exactly the same time. One car travels at 50 mph and one at 75 mph for 1 hour. You are trying to convince me that the two babies will actually have different ages? Again that makes no sense. The babies would have traveled the same amount of time however the distance would be different. - Reply to this comment
- "Two people start driving at point A. One person drives at 25 miles an hour and the other drives at 50 miles per hour. If each person travels for 1 hour is the person driving at 25 mph any older or younger than the person driving at 50 mph?"
That's a tough one because I am not an expert in the general relativity theory, but I think it has something to do with gravity as well as speed. Two people affected by the same gravity field may not be affected by the different speed variations since gravity can also slow or increase time. Or something like that. As I said, I'm not an expert.
But we can't travel AT the speed of light because time slows down to zero. Also, as speed increases, mass increases too. At the speed of light, mass becomes infinite. That's what makes traveling at the speed of light impossible. But as I said earlier, we can cheat to make it seem like we are travelling that fast, aka wormholes. - Reply to this comment

- The cells would be in an inertial frame of reference where they would adjust to the time dilation within the speeding craft.
But you folks are all locked into newtonian ideas of space travel. When star travel happens, it's going to use entirely new technology based on an entirely diffrent model of the universe. It will be more like the wormhole stuff you see in the movies. No one at this time can answer what is inside a black hole and the laws of physics that apply in there- or really even at the sub-atomic level of all atoms. We are still in the early stages of understanding these things. I am convinced that someone will figure out how to punch holes or tunnels in this universe and on some other planets they probaby already have.
There is an amazing amount of stuff we don't know on both the macro and micro levels of this universe and that scares governments. - Reply to this comment

in regaurds to that question..
read what i posted at 11:46 again only a few weeks went by for that person. so only a few weeks of biological effects. - Reply to this comment

Define age!!! if you define it as global time when you were born to global time now then both aged the same way. Time is relative to yourself tho so in ur scenario, althought the speeds are entirely to slow, yea the person driving faster experienced less time passing as compared to the other driver even tho the global time passed a set amount. - Reply to this comment

Thanks for the explanation. Another question. Does the theory take into account that the cells within the human body multiply and age at a constant rate regardless of outside factors? - Reply to this comment
- So Rafterman,
Two people start driving at point A. One person drives at 25 miles an hour and the other drives at 50 miles per hour. If each person travels for 1 hour is the person driving at 25 mph any older or younger than the person driving at 50 mph? - Reply to this comment

yea the people in the spacecraft would only experience a few weeks passing by or so but the people on earth watching the trip would experience 20 years going by. - Reply to this comment
- "Either way, a human leaving today traveling at the speed of light would be 7,300 days or 175,200 hours or 20 years older, take your pick. It is a fantasy."
Well, no. Einstein said in general relativity that time slows as you approach the speed of light. On Earth 20 years would pass, but in the vessel, you would not age in any perceptible way. We can even prove this on earth. An experiment with an atomic clock on an airline and another on the ground was carried out. In a cross country trip, the clock on the plane (which travelled at 500MPH) was a fraction of a second slower than the one on the ground, travelling at 0MPH. - Reply to this comment
- Stop whining neo-whining conservatives, this was paid for by the Europeans, guess you didn't read the article, just want to be cry-baby nay sayers.
In case you neo-conserves don't get it, and you don't, the reason all of the super powers fund this kind of research has nothing to do with pure science -- they're all afraid that one of these astro-physicists will be the next Einstein and discover some new weapons technology while they are "studying" the universe and how it works. You probably don't know that Einstein was considered a dolt by all of his professors, that's why he could only land a job in a patent office when he graduated college. That didn't stop him for providing the mathematical framework for the atomic bomb and atomic power in his spare time.
You think the folks of 150 years ago thought the average hick would be flying around the world in jet aircraft? Don't kid yourself, there are incredibly smart people out there who may well figure out how travel can be accomplished using means of energy and physics we can't even conceive of now and it could happen quickly. It's a very strange universe and that's why governments pay people to study it. Now please go type on the internet on your manual typewriters cry babies. - Reply to this comment
- "Let there be NO TOPIC that connot be converted into a Bush slam...lol"
Or a Clinton one, eh "didntinhale"?
It must be a sad and lonely life trolling the internets always needing to be ready to jump to the defense of your idiot leader personality cult.
And it must be even more galling having to defend his abysmal record by comparing it to one of the most successful administrations in US history (yes, I'm talking about Clinton's).
It's good for providing a laugh though. Rock on you crazy wingnut!!
LOL!! - Reply to this comment

Don't quote me but from what i understand in the miniscule speeds we can travel right now or the speeds we travel around the sun it will really have no effect on the time relative to us. (I have read a few things on this but i am no expert) (and for the most part these are just theorys, as with most all of science)
for some reason i think it was in one of stephen hawkings books but i have looked at alot of stuff like that and it is all blurred together. - Reply to this comment
- big_john_1,
Where did I say ANYTHING about traveling to this planet? Read the *** post before slamming it! The point I was trying to make is that just because you don't see a point to a particular line of research or field of study doesn't mean it won't eventually have benefits to someone in the future.
This is hopeless...I'm going on to another article now. B-bye. - Reply to this comment
- "Because unlike the "politically correct", I say what's on my mind."
Really? If that is actually true, you should be perpetually silent. One cannot read from a book of blank pages.
"I don't consider liberals to be "fellow Americans." I look upon them as one would look upon an appendage that serves no purpose other than to take resources away from the primay organism."
With that attitude, you're right: liberals are not your fellow Americans, because you are yourself un-American. Tolerance of dissent was one of the main tenets upon which this country was founded. I think you are an a$$, but nonetheless, you are my fellow American and have a right to your opinion, and if necessary I would fight to defend that right.
That you do not hold the same attitude makes you less worthy to be called an American, and you need to re-think your position and exercise a little intelligence and compassion. Despite the current administration's consisent attempts to show the opposite, it is in fact possible to be intelligent, compassionate and a conservative. - Reply to this comment
