not me,
E=mc2, for normal Matter it is and will not be possible to travel faster then light.
Under the special theory of relativity, a slower-than-light particle with nonzero rest mass needs infinite energy to accelerate
to the speed of light. Objects who traveling near the speed of light, cannot move faster, no matter how much energy it absorbs.
Its momentum and energy continue to increase without bounds, whereas its speed approaches a constant value—the speed of light.
As the object approaches the speed of light, the relativistic mass grows infinitely, because the kinetic energy grows infinitely and this energy is associated with mass.

and this is not science fiction...
but finding a "better way around this problem" you talking about is cheating! ;)


I do. I just don't think it will be any time soon.  Don't forget that the theory of relativity is just that, a theory.  Wont be long before it is destroyed by the next theory like it destroyed the old ones.  For a while there earth used to be flat and the sun was going around it.  Those theories seemed correct at the time and impossible to comprehend how they could not be true.  Give it time.  A looooong time lol

In particle colliders like the LHC, physicists use Einsteins E=mc2, to detect new particles.
LHC accelerate protons to 0.999999989 times the speed of light
a point where their kinetic energy exceeds their mass energy. When they collide their
huge kinetic energy can be converted, through E = mc2, into making new massive particles.

Theorys can be verified at the LHC or destroyed, a great tool.
The statement below is true.
The statement above is false.

A theory's a principle that exists only in human model space.  It's not an incantation.  It's always up for reassessment.

There's some major missing pieces to the puzzle. E.G. what is the origin of inertia?

If history has taught us nothing else. It has taught us to never pay too much attention to naysayers.
Its never been a matter if if something can be done. But in finding the way to do it.

“This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us.” –Western Union internal memo, 1876

“Everyone acquainted with the subject will recognize it as a conspicuous failure.” –Henry Morton, President of the Stevens Institute of Technology, on Edison’s light bulb, 1880

“The horse is here to stay but the automobile is only a novelty, a fad.” –The President of the Michigan Savings Bank advising Henry Ford’s lawyer not to invest in the Ford Motor Co., 1903.

“Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.” –Simon Newcomb; The Wright Brothers flew at Kittyhawk 18 months later

“Drill for oil? You mean drill into the ground to try and find oil? You’re crazy.” –Associates of Edwin L. Drake mocking his idea to drill for oil, 1859.

“How, sir, would you make a ship sail against the wind and currents by lighting a bonfire under her deck? I pray you, excuse me, I have not the time to listen to such nonsense.” –Napoleon Bonaparte, when told of Robert Fulton’s steamboat plans, 1800s

“Very interesting Whittle, my boy, but it will never work.” –Cambridge Aeronautics Professor, when shown Frank Whittle’s plan for the jet engine.



And one of my all time favorites

“To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth – all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances.”

–Lee DeForest, Inventor of the vacuum tube, 1926.

An interesting topic. I know I for one could sit and talk about the galaxy, other life-forms, and space in general all day long. It's abosolutely mind boggling, amazing subject. Many times I have come home at night, looked up into the crisp Maine sky, and seen the thousands of lights up there. It's on these nights that I get very little sleep. I keep myself up at night just thinking when I get on this subject!!

I think humans are a tad ignorant to think that we're the only intellignt life out there. As far as we know..."space" goes on forever. That's a long time...

I go camping every year at a lake that has very little to no light pollution.
We are very fortunate when we have a combination of no clouds, no wind, no moon, which also means the lake is like glass, I will take the family, friends, and all the kids out in the middle of the lake and shut it down and just look up in pure amazement at the details that you simply cant see otherwise, just beautiful.  With the waters reflection, you almost cant tell where the horizon starts or ends and gives you the feel of floating in space.   :aok

I think it is a pretty good measure.  No matter what the reasons, the result is the same.  Even the private sector has not been able to sell 5 day cruises around the moon and back  - for example - in 40 years.  That's what I mean by being way too optimistic.  If the private sector did not get it done in 40 years, I don;t expect the governments and politicians to do anything with any speed.
And there's a huge technology/funding step from the seemingly small difference of earth orbit to circumlunar.  As there is between sub-orbital and LEO.  A whole other ball game.

All I am saying is that it has taken 40 years and I cannot catch a space ride.  I not saying it will not happen.  Just saying it will take a little longer than what people think

Fiction?  Who said anything about fiction?  Its a theory questioned even by its own creator when tried to explain the universe.  It also requires the use of some goofy constants and assumptions in order to fit it/explain some of the things going on in he universe, or what we think the universe is.  I'm willing to be t that "the theory" would be changed/enhances/proven wrong way before we can catch flights to the moon as civilians.

Well, you know at least as well as I do that public opinion usually ain't worth much as soon as it concerns thick technical matters.

The problem with theories is that they are just that: theories. An unproven explanation of something new or puzzling. Some people put too much faith in theories. The thing is, theories are really just a hypothesis that which a scientist came up with to explain the unexplainable. Scientists often put their own spin on things when they have no evidence to prove something in order to formulate a more "complete" theory.

You cannot come up with a probability of life existing on another planet. We don't know how big the universe is. There has been no evidence of life existing on any other planet that we have researched save for our own. Once, and IF we do, discover life forms on other planets, we can then make a more reasonable conclusion on just how much life there is in the universe.

Basically, we must know how big the universe is, and find life forms on other planets in order to come up with a "probability" statement of finding life elsewhere.
