The best evidence for alien civilizations and the media isn't interested?

POINT EXPANDED

YOUR MOVE JUNKYARD TOM.

Aliens are a bit of an assumption. If they were spotted 200 years ago, we'd be calling them witches or something. In 100 years it could be something else. We mostly interpret them through the lens of our own culture. And besides, they're time travellers.

David Hilbert....some say he beat Einstein on several key equations by just days. He gave them to Einstein and Einstein submitted them as his own work. Hilbert was the better mathematician. Or else the arrived at the same theory within days.

As I said Hilbert found the action first, however Einstein had applied the mathematics far earlier.

So does quantum mechanics ..yet it violates GR ...

It doesn't. Quantum Mechanics and Relativity don't contradict each other in any prediction since they describe separate things.

Yeah it totally is ..its also violated IN PARTS in many technologies and phenomena though.

It's not. No violation of General Relativity has ever been observed.

GR has nothing to do with objective reality and have no relevance to the real world

It's directly applicable and related to the real world. It's used in satellites, nuclear reactors, etc

You have things backward I think. It's quantum mechanics that isn't about objective reality. It's only about experimental results.

You are incorrect on all three. If you can't see that I think you should admit you are not being genuine and you clearly don't know what you are talking about.


Local realism is an axiom of general relativity and it has been violated by quantum mechanics multiple times.

That doesn't mean general relativity as a WHOLE is wrong. But very incomplete.

There are some things and laws which general relativity and quantum mechanics MUST describe as being the same. And they don't. Or rather they don't yet as they both stand now.

There are multiple areas on which the two fields meet and be consistent with each other.

These are not areas for the most part with which either is focused on but they are there.

The double slit experiment. Wheeler's delayed choice experiment.

Einstein’s equations of classical general relativity predict that nothing, not even a light signal, escapes from inside the event horizon of a Schwarzschild black hole. However, in 1973, Stephen Hawking demonstrated an exception to this conclusion using quantum mechanics. Paired particles are constantly created and recombined in empty space. If this happens near a black hole sometimes on of the pair escapes ....its now called Hawkings radiation. After Stephen Hawkings.

And yes at this point they are absolutely in conflict. I remember this distinctly from a class in college.

GR and QM often talk about the same things ..but predict different things.


Again it doesn't mean the entirety of GR is wrong. Just incomplete. And yes GR and QM do describe common things sometimes albeit rather differently and contradictory.

Quantum Mechanics deals with matter, General Relativity with spacetime. The violation of local realism is for matter.


Name one.


That's not exactly what's going on in Hawking radiation, but even if it was they're being made outside the black hole so it's no problem for relativity that one can escape.


Name one.

Yes that is exactly what Hawkings radiation is.
Yes it is a problem for relativity ....according to relativity NOTHING can escape. Because relativity deals with gravitational PULL and this theory led Einstein to believe and predict that a black whole (USING HIS THEORY) would be SO STRONG so that NOTHING not even a single particle would escape. AND HE WAS WRONG. And so if he was wrong it might indicate his theory was wrong.

A black hole is a region of spacetime that exhibitsgravitationalacceleration so strong that nothing can escape according to the predicted results using the theory of General Relativity. That is wrong.

General Relativity deals with gravitation ..gravitation is caused by matter. It deals with beams of matter flung into space at speeds of light. It attempts to predict their course their speeds etc.

Well that was one axiom ...


What they both investigate describe.
Gravity.

Problematic Axiom : the speed of light is constant for all observers ...its not in a vacuum i.ie space

A black hole is a region of spacetime that exhibitsgravitationalacceleration so strong that nothing can escape according to the predicted results using the theory of General Relativity. That is wrong

Nothing can escape from inside the Horizon. In Hawking Radiation the particles are made outside the horizon so there is no contradiction with General Relativity.

Also the other axiom is the invariance of all physical laws. And QR DEFINITELY contradicts that.

No it doesn't. Quantum theory has the same invariance.

I'm fairly confident that if aliens did visit Earth us humans would have our collective egos bruised by the fact that they'd be here to see cats rather than us.

Isn’t relativity applied in building auto pilot systems and gps?

Actually.

No..i would know they are good peeps ..why wouldn't they want to see cats!??? That is all i am down here for!




BTW THIS IS MY TRUE FORM!

Is it possible to put this kitty pic as my avatar? ..i wanna put the kitty

As long as it's just the cats they want to eat I'm fine with that.

I will feed them you! :mad:

Ugh what's wrong with you??

I would imagine if someone had the technology to traverse trillions of miles to get here they wouldn't be buzzing around in our atmosphere waiting to be spotted.

So intelligent beings who have mastered technology to allow them travel the universe are worried about being spotted?? Why? In case we capture them with our Stone Age technology (compared to theirs)??

I firmly believe there are many many forms of life on other planets in the universe, to believe otherwise is small minded when you consider there are billions of planets out there. We are not alone.
