Doesn't gravity travel faster than light?

Or, was the gravity that we experience now created in the past and has traveled to us at light speed?
Nope, gravity has speed..

As Jupiter moved between Earth and the quasar, the gravitational bending of Jupiter allowed us to measure the speed of gravity, ruling out an infinite speed and determining that the speed of gravity was between 2.55 × 10^8 and 3.81 × 10^8 meters-per-second, completely consistent with Einstein's predictions.

Not a hope in hell, ever.

The energy requirements for any of the theories listed (or any others, for that matter) simply defy grasping in a real sense.

Do we really think the human race is showing any progress towards all agreeing that spending thousands and thousands of billions of pounds on a worldwide, unified approach to energy use?

Is anyone spending similar amounts on researching the equipment necessary?

No, every small-minded, petty nation is focussed on the next few years of spending on ensuring that their own lowest common denominators have their every whim catered for, such that they stay in power.

Science Fiction is an accurate description.

The atomic clock tests are faulty and time dilation is garbage. An atomic clock involves motion of matter, matter with mass, and anything of mass in motion around the earth will be affected by gravitational forces and suchlike. The difference in position and motion of the clocks on the aeroplane and on the ground explains why their times appeared different. Time didn't bend, the motion of the matter within the clock was affected and that is all.
There is no reason why the speed of light cannot be exceeded. All we have done as humans is seize upon it as some kind of limit.

However what will limit how fast we can go will be the method we would implement to navigate around celestial bodies.

I'm sure he will have all the math already worked out to replace relativity...

It was the dawn of a new age...

In time it will be replaced, or we'll understand so much more that it's been revised so far that it's no longer deemed applicable.

'and suchlike'

I'm not sure exactly what scientific process that is...

It seems you're utterly clueless on how science works so take your childish toys and go away.

Not sure that was called for.
What's your 'scientific' background?

You literally wrote a whole bunch of speculation with no basis, evidence or even theory why it would even be remotely true. You are at step 1 of science.

Whereas general relativity is fully worked out and at 'Benefits and outcome'. Things like GPS telling you within inches where you are on the world wouldnt be possible without it.

What about particle accelerator tests - also faulty and garbage?

https://en.wikipedia.org/wiki/Time_dilation_of_mov...

What about muon decay experiments conducted by observing cosmic ray collisions with the upper atmosphere - also faulty and garbage?

Science has been trying to dis/prove relativity since Einstein published it in 1905/1915, the brightest minds on the planet. Many experiments and practical applications.

How Science works is easy, just come up with something better!

And absolute zero is only quite cold.

There is no doubt that Einstein's theory will be replaced at some time in the future. There will be discoveries, theories and strange stuff that will show that, like Newton, it was OK while it lasted. We obviously don't know what will replace it, but it will almost certainly give rise to a best seller.

All scientists are wrong. That's what makes them so believable. All theories are working hypotheses. At the moment it is provable that nothing can travel faster than light. It is obvious to anyone with the slightest of grasps of relativity.

I reckon we will go faster than light by some method or other. It might not be measured in speed, i.e. we will change location faster that light can travel between the two points. However, I doubt it will be in the next few weeks.

We know relativity and particle physics dont quite meet in the middle. We know our understanding is incomplete.

Coming up with something that unifies both doesnt mean it will invalidate either.

The differences in the atomic clocks are simply physical and caused by gravitational influence on the movement of matter inside the devices. It's the effect on matter that causes the device to act as if time has somehow altered, an error, an illusion. To deny that is to deny the very forces that hold our world together. Perhaps one day, when we can set up such a test outside of the reference of our planet and without its influence, we will find less reason to attribute the results of the test to time dilation. Instead of sending one clock up in a plane and leaving one on earth, then leave one in space and send many others away in various specific directions and see what readings they give.

Exactly; incomplete, not wrong. This idea that all science theories are wrong and will be replaced is bunkum. Newton wasn't wrong, his maths is still used to send probes around the solar system, and will always be correct. So will Einstein.
Newton reckoned reckoned gravity was a force. Einstein disagreed. One of them has to be wrong.

Einstein was wrong about all sorts of things. That no one is right all the time is a cosmological constant.

Newtonian physics was used in the Apollo missions. But that makes the measurements correct, but leaves the theories. So do gravitational waves exist?

There are observations and measurements. These will remain. There are theories to explain the measurements and observations. These will change, at least they always have.

That's not, of course, to disparage these great modifiers of thought. They were geniuses. But their theories will be modified, and changed out of all recognition. One point where Newton will be unchallenged is that he saw further by standing on the shoulders of great men.

Wasn't Newton's quote a sarcastic dig at someone (Hooke?) who had claimed that Newton was riding on the efforts of others?

Besides, it's not as if that makes Newton or anyone else's contributions any less noteworthy.
