gravity

You see sci-fi movies and everyone on board the spaceship walks around like they have gravity. I this possible?

This article is a set of scientific facts, the results of my own research and their theoretical justification. I posted the article in separate posts to create a sufficient number of posts and get the opportunity to add video and images. Since antiquity, it was believed that all world space...

Follow this link: http://flight-light-and-spin.com/proof/instant-gravity.htm ...to see an astonishingly simple proof that gravity is actually instantaneous and does not travel at the velocity of light as the relativists believe it to. Do yourself a favor and take a day or two thinking about...

Dark matter continues to evade detection. I've read a few articles lately suggesting theories like Modified Newtonian Dynamics are being taken more seriously. Anyone working in the field have any comments on where things stand/are headed?

This article is a computational analysis of the theory of gravitational waves; as expressed within Einstein’s Theory of General Relativity and the wider realm of Astrophysics. Essentially a critique, this study has been written for the purpose of explaining the unobvious challenges faced in...

Hmm. Gravity can be produced, detected, and controlled claims scientist I red it here: http://www.dispatchtribunal.com/gravity-produced-detected-controlled/10585/ The abstract is here: http://arxiv.org/abs/1504.00333 Hits ALL the bases . . . except "quantum". :D The author of the paper...

It's official. The mainstream theory of gravity doesn't fit with observations. Satellite galaxies that orbit the Milky Way and Andromeda should be in a random distribution. What is found in reality is that they tend to be in thin disks which orbit in the same direction, like planets in the solar...

So, if the Moon really is formed from the conglomeration of debris created from the collision of another planet with Earth billions of years ago, how is it that as the particles combined, and the mass increased as a result, the orbit of the forming Moon didn't reduce increasingly to the point...

(From a Martian High School Space Ship Shop Class) (GROK?) (grok!) Einstein’s General Theory of Relativity appears to be seriously flawed. A reference Time Rate does not exist for the Universe! The Time Rate we experience is a local condition and is not a universal condition. The Time Rate is...

The paper I wish to cite can be found here: High precision thermal modeling of complex systems with application to the flyby and Pioneer anomaly Briefly, it explores thermal radiation pressure (TRP) as a possible explanation for the unanticipated velocities observed for the Rosetta and Pioneer...

Here's her Wiki page, and some of you may not know who she is, but she did something rather extraordinary among her peers - she got the attention of the Department of the Defense and apparently has disappeared from public view. http://en.wikipedia.org/wiki/Ning_Li_(physicist) Her team was...

We are familiar with the idea that mass and energy are equivalent from the famous equation E= mc2. If mass and energy are one and the same, why do we need two different forces- gravitational and electromagnetic? As photons ‘aggregate’ into matter, the resultant decrease in the number of ‘free...

I suggest that in pure empty space, devoid of mass or gravity, that the Flow of Time is infinite. Time stops at the speed of light, it will nearly stop for a mass traveling very close to the speed of light. When a gravitational field strength decreases, time flow increases. It has always been...

For some reason when I hear of ghosts I wonder if the ghost in question has mass and if it doesn't how gravity applies to a massless object and how an object without mass can move. I know gravity can bend light but can gravity hold a ghost in place. I know there are posters here who understand...

I just read an article about this in the Sept 25 edition of Science News: On the Origin of Gravity and the Laws of Newton: Erik Verlinde LINK LINK LINK Are any of the physicists here familiar with Verlinde's ideas? Any thoughts?

The other day I was watching a video of an atheist and a christian going at each other on a beach front debate. One of them mentions god stopping the sun for a day and the atheist says that would mean the earth would stop spinning and therefore we would all float off into space if that happened...

Since some of our resident Truthers still insist that gravity wasn't the cause of WTC1, 2 & 7 falling to the ground & that they were brought down by "explosives", it's only logical that they would defy gravity, atleast in Trutherland. Sir Issac Newton would be laughing in his grave about that...

Hi guys, I need some help from a physics Guru, even if it is to tell me I'm wrong so I can drop it. On an Aviation forum, a discussion came up regarding the forces on an aircraft in a turn. As you'd be aware, and aircraft in a 60deg Angle of Bank turn experiences 2g. People started refering...

I was wondering what happens to acceleration as you approach the singularity of a black hole? Acceleration is dependent on gravity according to Newton. If gravity increases to infinity at the singularity what happens to an objects acceleration as it approaches the singularity? Would the...

- In 100 years we have known that space around an astronomic body bends 1.) But what is “bended space” really? 2.) How can matter connect with space billion of miles away and bend space that fare away? 3.) How can matter cause space to “bend”? 4.) Can space bend without a force / energy is...

So, I'm driving up the ramp at the multi-storey car park at work, and whilst it's pretty steep I realize that I can accelerate up it (somewhat surprising for a 1200cc car, but there you go!), and it starts me thinking about escape velocity. And it leaves me wondering: If the ramp were...

A new episode of the History channel's Universe series: What would happen if the moon disappeared? Seems ironic, given the recent thread on what would happen if the moon doubled in size. According to the show, two things mainly: The tides held by the moon would run off, causing "powerful...

Gravity and the fine-structure constant. Well there has never been any shortage of crazy Ideas being posted on this forum, so I figured I might give it a shot myself. The only difference is that I know this idea has no theoretical basis as far as I know and would just amount to some...

So I've seen all of these arm-chair "physicists" come around talking this and that about relativity, and how they think it works. Accompanied, of course, by the fairly rapid smackdown courtesy of people on these boards who know what they're doing. Hopefully, same people can help me out with...

Ajay Sharma is a teacher of physics, who sprung to fame due to of course, the media. When changing something in physics is considered a big thing, it's usually someone tampering with the master equations of physics history, one most notably for its popularity is the E=Mc^2 conservation equation...

There have been many strange physics claims made by "single topic", obsessive, fight-picking, drive-by posters in the time I have been observing here, and most seem to be quickly dispatched by the many knowledgeable members here. Recently, there were two that I am not sure were directly...

(One thread inspires another. ;) ) If a large spherical hollow chamber, perhaps 1000 miles in diameter, was created with its center exactly at the center of the Earth, what gravitational force would be felt at various points within the sphere?

I'm once again exposing my almost total lack of physics knowledge, but that's why I'm here :) Q1: A person in Finland is standing on top of a 100 m building. He has two bowling balls with him. They are indentical in size, but the other one weighs 10 kg and the other one weighs 100 kg. The...

If you're bored with the usual Google search, try Google Gravity: you'll have to work just a little bit harder than usual to type in your query. It looks like some very clever JavaScript programming has been going on there.

I need some help trying to understand why the graviton is postulated to exist in physics? I thought Special Relativity 'explains' gravity, that is Gravity is due to the shape and size of the universe? I have tried Wikipedia and Google but can't find exactly what I am looking for, I have read...
