Have Aliens visited Earth

Now debate on whether they have visited Earth.

I say it's 50/50

How is it mathematically impossible?

Unclear what this bump has to do with Hillis.

With an "endless" supply of anti-matter, or the ability to create it on the go from galactic "debris" or whatever, one could accelerate a spaceship indefinitely. Never reaching the speed of light but continuing to incrementally get closer to it (99.9%, 99.99%, 99.999%). Mathematically, accelerating this way one could travel the ENTIRE universe in roughly 12 local years (relativistic effects would mean quadrillions of years on Earth, closer to the speed of light you get, slower time moves for you locally though). Acceleration at 1G, which solves the lack of gravity issue.

Anyone who said "No, Mathematically impossible" sould read this post. However, the amount of time passage outside the ship would be a problem.

why isn't anyone calling each other gay in this thread? I havent seen one nut dragging comment or reference to someone being retarded....

no Hillis, Cutler, Marshall, McDaniels or Shanahan reference?

this thread is lame

How would anti-matter propel you through the universe? It would instantly destroy any matter it touches. That means your ship and you. How would it be used as a fuel?

There was a Hillis reference just above your post you dumb gay nut rubbing piece of crap.

and we have completed all quotas....

Containment would defiantly be an obstacle.

Just put it in an anti-antimatter jar. Duh.

Now that we've solved that problem, we can move on to production.

Simple. Just have matter trade hillis.

The hangup many of us have about the possibility of visitation is the distance between stars and the immense amounts of time traveling by conventional means from here to there. I'd think we're being a bit short-sighted about that.

My feeling is that the next breakthrough in space travel, when we find it, will seem to come right out of left field somewhere. It'll be the work of a team, a department, maybe even a single scientist who's able to suspend her preconceptions about our understanding of physics to see a whole new way of doing things. Something that we just haven't seen yet, but the math adds up so that 2+3+1+1=7 as surely as 1+1+1+1+1+1+1=7.

My guess is that The Discovery will look something like quantum entanglement: the realization that distance is an illusion of scale, but the underlying... nature... of the beast is infinite and eternal on the near, short end as much as the long, far end. We're seeing first experiments already with quantum entanglements, where a variation in the motion of one particle instantly changes the motion of its entangled partner. The distance between them does not seem to matter. The current experiments have an eye toward possible development of quantum communications and computing. The theories in place now might be enough to support the development of a simple quantum Morse code.

Just as an off-hand, first-try thought: what would it mean to have instantaneous data transfer and command capabilities with the satellites studying Saturn? Quantum communications like that might not be subject to the speed of light limits. Remember that the speed of light is, by definition, the speed of light in relation to the observer and environment of the observation.

If the speed of light is a chalk streak across a chalkboard, does the speed of light apply to sending a ripple of energy through the chalkboard itself?

Whatever "The Discovery" proves to be, it's going to challenge (and possibly change) everything we think we know about ourselves and the universe. And all of a sudden, we just might find that Alpha Centauri really is "just around the corner and down four blocks" after all.

2 quick physics notes on that.

1. It has not been proven yet that entanglement does break non-locality given that the entangled particles have been able to exchange information about their states when they were created.

2. The speed of light is not relative to an observer but is identical for any reference frame, this is due to time dilation and length contraction.

Would you want to meet a being from another planet? Its not going to be like ET. I tend to agree with Hawking. We cannot assume aliens would be benign. They would come here to take what they need and move on...like ID4, but without a wisecracking pilot and an eco-nerd who is also a hacker saving the planet.

the idea of man walking on the moon was thought to be absurd as recently as the 50's though. Accepted potential reality changes along with science.

I personally believe that extraterrestrial races must exist, mathematics dictates as such.

If they do, in the numbers and varying levels of advancement that the very same math predicts, than the idea that they have been to Earth is a reasonable likelihood.

Therefore I personally believe that beings from other planets have indeed been here. We've already been to Mars, and we are much younger than many of these ETs must be.

Good points. Also, would gandalf really beat Harry potter in a wizard duel?

Yes he would, Harry Potter is still in school and Gandalf can ensure Potter will never pass.

Ultimately I think we can all agree that in a battle-royale of wizards Oscar Zoroaster Phadrig Isaac Norman Henkel Emmannuel Ambroise Diggs would win.

As for containment of antimatter, with strong enough laser and magnetic fields it can be contained, but ultimately containment is not the interesting part, the interesting part would be operating a huge magnetic ram scoop to gather up anti particles and focus them into a point where a stream of regular particles are injected, the annihilation will produce energy which can be absorbed and used for thrust.

All I understood was "thrust."

[Boomhauer]

There's zero evidence of such, but ALH84001 could prove to have brought dead aliens to Earth.
From Astrobiology.com
"In August 1996, our research team made a rather profound claim: evidence of fossilized life found within a meteorite (ALH84001) blasted off the surface of Mars. Where there's fossils, one can surmise there was once life. To be confident that a sample (from this or any other planet) contains evidence of past life or biogenic activity (i.e. the byproducts of organisms) one must determine beyond a shadow-of-doubt that certain well-established features or "biomarkers" (life's signatures) are present in the sample.

In the case of Martian samples, the criteria for past life have not yet been established yet. The reason for this is simple: if life existed on Mars, we currently have no way of knowing much - if anything - about its nature, ecology, or evolution. Such a detailed history (if it exists) will not be unraveled until we've spent a fair amount of time on Mars with robots and eventually humans. ..."

That is kind of backwards, is it not? Time dilation and length contraction is due to the constant speed of light, one of the two postulates of special relativity

[NUB]

I once saw aircraft during night that acted regardless of normal physics before disappearing from plain sight. Either aliens are roaming about, or our military has some really kickass weaponry they're keeping secret.

The Sumerian Culture, which dates back to 6,000 BC, is the oldest known culture on Earth. Interesting what they write about the Anunnaki in their tablets and carvings.

Google Sumerian and Anunnaki and decide for yourself.

Is everybody on the OM a theoretical physics?

[Bronco Yoda]

No, but we all have stayed at a Holiday Inn. gyldenlove lives there now that the misses kicked him out.

[Inquisitive Encyclopedic Insomniac]

Of course they visited, they come all the time. They just keep waiting to find intelligent life. I think they have a poll as too how far backwards our intelligence as a species is going
