The Case Against ETs visiting Earth

Don't be silly! Of course we will be able to travel faster than light.

No one thought that we could break the sound barrier, and we did.

The sound barrier and light barrier are totally different things, just because we were able to break one in no way means we will be able to break the other. The people who thought that we would not be able to break the sound barrier did not think so because of any scientific research, they probably just didn't think we could do it.

People have made light slow down to walking pace using a Bose Einstein Condensate, and have sped light up, getting a photon to travel faster than the theoretical maximum.

You can slow light down by putting air or water in it's way too! Slowing it down is in no way comparable to making it travel faster then it does in a vacuum, which by the way no one has ever been able to do.

IMO it's far more likely our "visits" are from the future rather than from aliens.

Dont tell me, you are one of these people that think teleportation hasn't happened yet!

Oh to be uneducated.

:rolleyes::rolleyes:

You hardly make yourself sound educated, so far you've just been stating scientific inaccuracies as well as mocking someone regards teleportation which was something they never came close to commenting on.
 
Surely were the toilet pan of the universe?

Why would they WANT to visit us?

If were are the most civilised/intelligent ones out there.. OH DEAR.

Also, why do aliens have to be more advanced than us?

What is to say there is not another civilisation out the there who are just entering their Jurassic age?

Is it not possible that our understanding of physics will simply continue to grow? We are far from knowing anything about the true nature of reality and matter.

Yes, by all means all of mankind's knowledge on physics could be wrong. A possibility. But going back to the ample of going from Europe to Australia 200 years ago doesn't apply to modern day knowledge of going faster than light. Npo one 200 years ago didn't think it would not be possible to go faster and the scientific knowledge at the time suggested it would be possible. The current situation is different. Its not just a case of building a faster space ship, or more energy, or a better energy source. Something majorly different needs to change - something which most scientists believe is impossible.
 
Well they'd have to visit us to find out that we're the toilet pan of the universe :p

Also, stereotypical alien is about 4 foot tall with an overly sized head and eyes. We must look so beautiful to them ;)

Do you also believe in ghosts and lizard people?

Erm what? Ghosts and lizard people are imaginary, stars are actually real. Or will you dispute that too.

Its a fairly good estimation, and a nice real world comparison which I thought people would appreciate to put the vast number of stars in existence into context.

Clearly my efforts were in vein.

We all know quantum entanglement happens FASTER than the speed of light, so we have done it already.

I find it funny that people with no imagination wish to mock others, and keep their minds closed to the exciting advances in science.

The people from the future arguement is plausible also, as this would explain why "spacecraft" do not land in populated areas, or come and say hello.

Clearly this is not proven and might well be unlikely, but why close your mind to it and dismiss everyone who thinks about it as a LIZARD MAN, or a foil hat loser.

No object with mass can reach the speed of light.

In THEORY. But we all used to think that the standard model was the be all and end all, and now we have massive, massive gains in knowledge of Quantum Mechanics which will define the fabric of the Universe soon.

I dont see your point? It is impossible for an object with resting mass to reach the speed of light as they would need infinate energy which is impossible.

Firstly what on Earth makes you think quantum entanglement is something 'we all know about'? Secondly it does not transfer any information faster then the speed of light as shown by Eberhard. This has be known for a long time.
 
So your a Scientist?

I love it how people have been conditioned to believe that all laws of Science must be cold hard fact, and can never be wrong.

There have been a few experiments like Quantum tunnelling that have "broken" the speed restricion.

Anyway, the speed of light is covered by Einstiens theory of relativity, which is 100% accepted as breaking down when it comes to Quantum mechanics.

So, its not at all straightforward.

Entanglement means that the spin of a quantum entangled photon matches that of its engtangled other.

When the spin is changed it changes in both, therefore the information of spin is transferred faster than the speed of light.

I never said it couldn't be done, just that it hasn't been done. Special relativity isn't 100% accepted as breaking down in QM and you can use quantum field theory understand why. Of course since QM is relatively new it is not complete so debate is alive and well. But to hold the opinion that QM has proven FTL is possible shows you have no idea of the subject.

EDIT: Actually on thinking about it I'm pretty sure you're confusing special relativity and general relativity. Here the results of the differing theories will differ but this is due to them operating in different experimental domains. i.e. you only observe GR with massive objects and QM is only observable with very small objects.

Yeah anyway, back to the topic.

As I said, the Mexican and Japanese government, as well as astronauts and other famous/important people have acknowledged UFOs (not made by humans). Tens of thousands of people have witnessed UFOs (that seem otherworldly). There are many pictures and videos on the internet taken from all around the world. So despite the mounting evidence, why do you continue to refuse to believe that it is possible ETs are visiting/scouting the Earth?
 
Oh god...

...another thread full of posts by people that have inside knowledge of alien technology and laws.

Me human. Me know all of universe. Me know that this other thing cannot happen because me learn from school. Me know other being not exist because me know all!

Ignorant puny humans :p
