Andrea Ghez’s Black Hole Research Confirms Einstein’s Theory of Relativity | Short Film Showcase

5824 ratings | 221810 views
For the past 23 years Andrea Ghez, professor of physics and astronomy at UCLA, has been collecting data on stars that orbit black holes. She found that their motion provided an opportunity to test the fundamental laws of physics. “We asked how gravity behaves near a supermassive black hole and whether Einstein’s theory is telling us the full story. ”Einstein’s 1915 theory of general relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. “In Newton’s version of gravity, space and time are separate, and do not co-mingle; under Einstein, they get completely co-mingled near a black hole,” she said. Ghez's research is the most detailed study ever conducted into the supermassive black hole and Einstein’s theory of general relativity. ➡ Subscribe: http://bit.ly/NatGeoSubscribe ➡ Get More Short Film Showcase: http://bit.ly/ShortFilmShowcase #NationalGeographic #AndreaGhez #ShortFilmShowcase About Short Film Showcase: The Short Film Showcase spotlights exceptional short videos created by filmmakers from around the web and selected by National Geographic editors.

When a star has a close encounter with a supermassive black hole, it gives astronomers a chance to put Einstein to the test. What intrigues you the most about Andrea Ghez's research?

She's done it for 20+ years and only tells us about women struggles, with no mention of breakthrough or confirmation of anything. Very self-serving video that shows no accomplishments other than fooling someone into paying her for looking through telescopes all these years. It's fitting she showed us her telescopes at 'Keck' observatory.

I've been watching some sort of this kind of videos lately and I have some thoughts playing in mind. This is my thought, what if the universe is like a computer harddrive? Where all other galaxies are the state of our own galaxy today. Or simply like a chunks of memories. And another one, it can also be like a human brain. When we are remembering some events in our life, we are in present and we are not actually there. Just like, when humans is looking in a space telescope, we can see other galaxies but we are not actually there. Then I think about this blackholes is like a link to actually get there. Crazy right? Hahaha.

I can't believe that a genius scientist has come up with such a theory as to change the history of science. What's more surprising is the content of his theory. I can't imagine what's in Einstein's head.

I use to have dreams about a black hole 🕳 coming on the earth 🌎 sucking everyone up.. this was before I even had heard of anything like this.. then another dream about the ground caving in.. they were this big house 🏠 we all was in it and I looked out the window to see the ground crumbling beneath us! Then they was this ship like a space ship 🚀 that we get in if we want to live.. uhhhh yeah pretty messed up lol.. idk 😐 why but I use to have this dream constantly.. that was about 22 years ago

Do most physicists agree that black holes are super dense spheres of mass (not unlike neutron stars, red dwarfs, etc) that have become dense and massive enough that their event horizon diameter exceeds the sphere’s diameter, going black (and that the sphere remains)?

What if it's a galactic plasmoid that charges up to a threshold, fed from plasma filaments from the greater universe, then after reaching threshold, releases a massive electrical charge - exhibiting what we see as a controlled, tight line of electromagnetic energy being dispersed much farther than what should theoretically be dispersed into a vacuum. What if this plasmoid is the reason behind the cyclical fluctuation of OUR sun, that is fed by birkeland currents stringing the galexy, galactic stars, and solar planets, causing fluctuations in our jetstreams and auroraborealis. Resulting in the recent and historical weather changes for specific latitudes. This "black hole" IS a THEORY.

In a nut shell. Einsteins theory of relativity is a coordinate system, which successfully accounts for when objects point coincide and interact in space. The theory of spacetime curvature prescribes a small deviation from previous theories, of Newtons laws of motion and gravity. But all you need to do to modify Newtons laws of motion to achieve the same results of spacetime theory, is recognise a property of the world that is well termed "force dilation". Force dilation is empirically observable, definable, measureable. Force dilation which is entirely equivalent to effect of time dilation. Time dilation and force dilation are two sides of a same observation. Please consider the following......... A modulated rate of a force driven system, represents a modulated value of that systems internal forces. This is empirical fact. Furthermore, Time dilation effect is defined by "modulated rates of clocks", clocks which are force driven systems. Force dilation effect corresponds to time dilation effect. Modulate forces, and the points at which objects point coincide in space are modified. For the same reason that a ball thrown harder arrives at the other side of the yard quicker. Force dilation. But of course I say this knowing I speak to my self. I say with no disrespect, but you are so confused that you cant even recognize a simple empirical verifiable truth when you see and hear it. these are the facts

I have a million dollar question for you. How do we know that the black hole is actually a hole?
Itube Collection (27 days ago)
@Renaissance Tides it's a actually a gravity point that's so dens and strong that it looks like a hole...the matter could be 4-5 sun masses up to countles sun masses pressed in one small spot..they know alot about black holes but still it's a big mysterie cause the laws of nature fall apart in there...

I think black hole exist to transfer a specific galaxy to another universe For an example we were once a sperm cells and then we pop and we go into a stomach and then we pop out to another hole but this time we’re a physical form For galaxy I think it a life cycle for them but they are in a whole different realm and dimensions it impossible to communicate with them and understand their life

Ranjit Keluskar (1 month ago)
An idea about the black hole needs to be revised. Actually, it is a cryogenic dense mass below zero Kelvin made up of anti-matter formed by the split at the beginning ,forming galaxies at the periphery and the black holes in the middle. We can not observe the black hole because objects at cryogenic temperature do not radiate and not from singularity or supergravity.

Cris006 (1 month ago)
so if a Black Hole is the nature's proof that there are stronger forces to overcome the light itself (aka speed of light), WHY are we limiting ourselves to believe there is nothing grater or faster than the speed of light just because Einstein found a formula that can be applcable in most cases. MOST cases. Even in the video they say "we do not have the physics to understand what a black hole is". What about leaving a door open to other newgen formulas, and not close them just because of some big old physician names, as they did in the past for Nikolae Tesla... just saying' ...
