Rumors Are Flying That We Finally Found Gravitational Waves

a reply to: OneGoal

whenever i thought about wavelength, i thought it must be measured in km.

The shortest gravitational waves have wavelengths measured in kilometres. Thousands of kilometres.

You can see a diagram here.

That page, by the way, is a good, easy summary of the topic, much better than the Wikipedia entry on gravitational waves.

LOL, I was being sarcastic. Yes typing on the phone is always a pleasure.

How can they mesure gravity untill this?

Drop something dense whose mass m you know from a height h. Measure the time t it takes to fall to the ground. Use Newton’s formula

s = gt^2/2

to measure the acceleration g due to gravity.

Then use the formula

F = mg

(also Newton’s) to find the force of gravity.

Alternatively, measure the distance from the object of mass m to the centre of Earth. Call this distance r. Then the force of gravity is given by

F = GmM/r^2

where M is Earth’s mass and G is a numerical value known as the Gravitational Constant.

As yet, no one has managed to show Einstein wrong.

Sir, I give you:

Niels Bohr
Wolfgang Pauli
Werner Heisenberg
Louis de Broglie
Erwin Schrödinger

Context. That being relativity and gravitation

But that was not a formal claim based on theory. More an expression of his distaste for the reliance of quantum mechanics on probabilities.

Cheers thanks for the link

Ahh. Understood. Sometimes it's hard to tell nowadays,

True, because Einstein was an honest man and an unyieldingly rigorous scientist.

Following the development of General Relativity, he spent the rest of his life trying to find a unified theory of physics that would eliminate quantum uncertainty. He never got anywhere with this — more fundamental forces and particles were being discovered as he grew older, making the quest increasingly futile — but he never let go of his conviction that the quantum mechanists were wrong. But they weren’t — he was.

You are quite right that relativity (both theories) have never been proved wrong, neither has (to my knowledge) any of his other published work.

The thought of spacetime being massless matter makes my head hurt.

Damn you gravitons!

What practical applications can be made out of this discover?

Other than, once again, showing that Einstein was right?
Gnarly barrels dude!

Meh, he is overated.

The real discoveries in science is happening on youtube but the establishment refuses to watch the videos.

Einstein couldn't get passed the law of physics,math and science , these guys on youtube don't let themselves be constraints by math ,science or physics.

An awful lot of YouTube "science" topics are just silly.

Generally, if someone states that something they can demonstrate is unexplained by science or not accepted by scientists, it indicates only that they don't know what is happening or are telling porkies or are in denial about the mundane nature of the phenomenon.

You forgot Einstein himself. All that mess about the cosmological constant.

You need an anti gravity bubble that is both repelled and pulled along at the same time so as to ride the wave so to speak...
Then if you can amplify the strength of your anti gravity bubble you will have the means for acceleration...
At the same time you would be immune to the g forces which impose boundaries for human bodies...
What's more you would have a greater then light speed capable time travelling machine...

You keep taling about the properties of gravitational waves when they haven't even been proven to exist yet.

Can anyone explain how these waves keep me from foating of into space?

there's no such thing as gravity, or gravity waves

a reply to: Phage

Gravitational waves have a very large wavelength. You need something big to find them.

Right. I would say you have to find them first before you can make statements about their properties. What exactly are you basing your claims on about these waves that are yet to be proven to exist?

Wow, for someone professing to be an electrical technician, you should re-read your manuals.
Tesla was a great engineer who perfected the mechanisms for domestic AC power distribution, however he certainly did not invent AC, no more than Edison invented DC.

I'm sure someone back in the stone age found a relationship between a spinning magnet and some ironstone ? but to build a machine to harness it for use is a totally different story. Don't be confused with discovered and invented ok.

Second hand gravity waves, and other stuff..perhaps.

A common misconception. Gravity waves are atmospheric waves. Unrelated to gravitational waves.

Correct!

Mind you, I liked the old term of Gravitational Radiation for Gravitational waves, much more scarrrrrry.

Another of our nefarious plots exposed due to science. Curses, you pesky kids, get back in your van and leave us alone.

Right!!!

That is why we should be thankful for Galileo Ferraris who had a working AC motor almost two years before Tesla.

Is the em drive tapping into this?
