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

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.

    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?

  • ari wiguna on January 21, 2021

    why not explore our planet earth first? depth of forest, ocean, sand, ice still untouchable I'm sure there must be natural resources that allow humans to go to other planets …….try to think if aliens can go to another planet they must have resources on their planet, it is impossible to venture to another planet to find resources first

    Congratulations ma'am on winning Nobel Prize✨

  • Farid Fadil on February 18, 2021

    fun fact, 0:15, in normal observing conditions, the observatory would be completely pitch black inside. So it will be you and the stars.

  • Baby_Siya on March 2, 2021

    I hve a theory for that that is second world ….is black whole and that will become true

  • Goes Boom on March 4, 2021

    So does a black he stop time? Or maybe it is so strong it can rewind time?

  • Mohith Maruvada on March 24, 2021

    Music name plz

  • Mohith Maruvada on March 24, 2021

    Loved it

    Really inspired

    What causes the warped space around a black hole?

    If black holes gravity is SO strong why do objects circle around them?

    How does gravity reach out so far from objects, when gravity is so weak?

    Because, the warped space around a black hole is caused by the black holes mass and density displaces space itself (normally referred to as spacetime).

    Because spacetime is displaced it is now abundant around the black hole. Spacetime is now in multiples around the black hole. THIS is what reaches out so far, not gravity. Be it, this is what causes what we call gravity.

    Now that spacetime is abundant (in multiples of itself) around the black hole, and because our universe is constantly expanding, gravity is created.
    Basically, objects displacement of spacetime causes multiples of spacetime. The more multiples of spacetime the more gravity you have.

    Notice how objects in space hardly ever collide head on? Why not? If "mass attracts mass"….
    It's the warped spacetime that extends out from objects that causes other objects trajectory to change and travel toward the other.

    They don't collide head on because the constant expansion of space causes objects to travel just outside of other objects.

    Seen videos saying"an apple doesn't fall to earth, earth travels towards the apple"? This is true. Our reality is constantly expanding. If the universe wasn't expanding, and if objects didn't displace spacetime causing multiples of spacetime, we wouldn't have gravity.

    The moon's gravity is weak because it's core isn't dense. Earth's core is dense so our gravity is stronger.
    Black holes are the most dense objects in space. Hence the strongest gravity.

    Theory will catch on eventually. There's to many flaws in the "mass attracts mass" gravity Theory.

    BTW, radio waves and light slow down (experience different time, actually) when travel close to a black hole because there are multiples of spacetime present. NOT because gravity……or because of a warped spacetime.

    Time and space are one in the same. One can not exist without the other…

    No, Einstein said in a 1970 paper that black holes were impossible. Objects compress and increase their spin and centripetal force which cancels out gravitational inward pressure. Hawking in 2014 said he was wrong and that black holes don't exist as well. The m87 image is a donut shaped plasmoid at a 90 degree angle. We've seen plasmoids in lab and know they exist. Our own galaxy has one at the center; Saggitarias A.

    We need more Andreas in the world

    I am very interested in astrophysics and how the universe works around us, that dynamic and incredible system that we are related with. Once when I was young I asked a teacher if it would be possible to send all the garbage on earth to space, close to a black hole, since it could just "eat it" and then it would solve our environmental issues lol. It’s amazing to see that there are people analyzing those phenomena and trying to discover all the secrets that are still hidden. As a curious person (‘scientific gossipy’ as I like to say) it’s kind of exciting to know each discovery that scientists share with the world.

  • Comment Drops on September 14, 2021

    I found the video very interesting and challenging. A very complex topic about black holes and a theory by Albert Einstein. The study managed to relate stars to black holes. Andrea is a brilliant, persistent and patient scientist. She says it's like the stars dance around the black hole, which she finds very poetic. She still wants to improve the ability to understand the stars even after such a ground-breaking finding.

    Everything is a torus.. Black holes included.. A black hole is just the center of a magnetic field.. No big deal.. Light does escape though… At the point of centrifugal convergence..

  • A riba on December 10, 2021

    Ever into a black hole? Feel the gravity in it?

  • Kockarot on December 20, 2021

    PFFFFFFFFT einstein rufused to believe in them cause he did not like the REAL SCIENTIST that did theorize there existence. Even that that scientist unlike einstein, actually fought in WWII. But he was killed in the war and einstein wasnt going to give this guy credit even after he made the ultimate sacrifice. Then decades later everybody thinks it was einstein who figured them out. FOR SHAME ON HIM

    I lost all respect of eistein because of this treacherous behaviour to another scientist.

    GOOD DAY ALL and sorry to have possibly been responsible for change in opinion of the criminal. He may not have had to go to war and die if einstein backed all of his evidence.
