Brian Greene Explains The Science Behind Wormholes

The American theoretical physicist, Brian Greene explains the science behind wormholes. Wormholes are a popular feature of science fiction as they allow interstellar travel within human timescales. The problem with using wormholes to travel in space or time is that they are inherently unstable. To stabilize a wormhole you need materials that have negative energy density, at least in some reference frame. No classical matter can do this, but it is possible that quantum fluctuations in various fields might be able to.

Brian Greene also explains how two black holes can be attached to another via an Einstein Rosen Bridge or more famously known a wormhole. The idea is based on General Relativity, which predicts how space and time warp in various ways under certain conditions. According to that theory, there are discrete parts of the universe where space and time are independent of one another.

The impossibility of faster-than-light relative speed only applies locally. Wormholes might allow faster-than-light travel by ensuring that the speed of light is not exceeded locally at any time. While traveling through a wormhole, slower-than-light speeds are used. If two points are connected by a wormhole whose length is shorter than the distance between them outside the wormhole, the time taken to traverse it could be less than the time it would take a light beam to make the journey if it took a path through the space outside the wormhole. However, a light beam traveling through the same wormhole would beat the traveller.

Brian Greene admits that wormholes have not yet been proven to exist in the real world. Their existence is only inferred based on a mathematical framework.

Perhaps someday humans might be able to travel through a wormhole to visit other parts of the universe. Whether wormholes are really possible, or are just part of science fiction, remains to be seen. The only thing certain at this time is that scientists are still working hard to find out more about them.

“ no worms are harmed making this video”

[andrewschuschu]

Always had this weird thought that all time exists at once. It’s not a sequential thing per say but a layer of a dimension. In that layer that’s how we experience our lives. Every universe is an explosion of matter in space that is the same expression of matter just in a different order. The central black holes are a time transit back in time to the same explosion and matter.

The science behind wormholes in 10 minutes, THANK YOU YouTube 😂👍

[KngAlexander]

Shoutout to the camera guy that captured all this 🫡

Even if you keep the wormhole open how can you go through it is it literally an absence of fabric of spacetime. You are made of matter and need to travel on a path of spacetime fabric. Unless you create a wormhole with a tunnel of spacetime inside so you can travel there to the different exit

[mki]

This is such a visually stunning depiction of Science and Beauty. Thank you.

A wormhole would likely be extremely hard to see even if it was large.
It would probably not be a tunnel but more like an orb shaped door, where you step through and you're there.
No swirly tunnels.
Just stars on your side, and different stars visible through it.

The reason being, that a wormhole would be a point of space physically connected to another point of space, folded through the 4th dimension until the two points touched, like how the portals in the game portal work, except the portal would be a 3 dimensional shape, rather than a 2d hole.
To use a wormhole to travel backwards or forward in time youd need to connect two points by folding 4 dimensional space through a 5th dimension.

WOW! This Mind boggling subject is beautifully illustrated in this EXCELLENT video!

I also thought passing through abunch of electrons that are partnered to electrons at another place, would anything be transferred at all, an if so, what and how

@Science Time To further analyze the effect of gravity on time - It is said that a strong gravity field slows down the clocks and even the thoughts of a person which is found in that strong gravity field. Very precise clocks were mounted on planes flying at high altitude around the planet. In that experiment the altitude and the speed of the planes were taken into consideration and it was proven that the gravity and the speed have an effect on time. I wonder if we could make the following experiment - By my understanding, "the movement" of the electrons in the atoms of our brains/our bodies is the thing that gives us, beside the sens of time passing, our thoughts/our ability to think and the speed at which we think/our perception of life. In the experiment involving the clocks on airplanes the result of the behavior of the whole clocks were analyzed. Can we make the same experiments involving electrons only? Is there a property of the electrons that can be measured using today's technology? Can we put some electrons on some airplanes and measure their properties while flying at high altitude? I know the physicists would tell me: "We cannot say that the electrons are moving. We can only say what is the probability to find an electron at a certain position inside the atom". But maybe there is a property of the electron that, when running that experiment, we can notice it slowing down. Hint - Electricity is also a result of the "moving" electrons. Can we make precise measurements of the properties of the electricity at high altitude? Maybe by analyzing the properties of the electricity at high altitude and compare the results with the results of the same experiment made here on earth, we can find some differences. And those differences can tell us something about the "movement" of the electrons and how the gravity affects it. I am talking about a device consisting of an electricity source, a wire and a consumer. Thanks!

You would never come out of the other side, unless you close the connection the moment you get through because who's to say how much of you will stay through before being sucked back into the blackhole you just came out of? You'd have to leave the connection open forever and spend eternity stuck between two black holes. Where apparently time slows and our thoughts. Sounds like purgatory.

[ecyqqxh]

I think this is the perfect video to fall asleep for the next couple of weeks, I’ve been using the Black Holes by Brian Cox until now

[science]

space and time in the univers
what is univers?

[markmccormick]

A lot of things come to mind, how could we even travel through one how would we communicate if successful, what if it collapses while passing through, can we survive in a ship built to withstand extreme temperatures and forces of gravity

[kobuslabuschagne]

Would you not become anti matter if you traveled faster than light?

[Greenr]

There are stories that various native people went into wormholes on earth to other places. If physics says wormholes are consisted of two black holes touching one another, then it would only mean that black holes exist on earth, right?

[stefanusayudha]

i have a question.. string theory says we lived in 10 dimensional universe

and we know time and space can bend.. does the 6 other also bend able? can we bend probability and what sains says about it..

[TopSecretTeletubbyAgent]

If someone else has said it already, ill reiterate. In the realm of possibilities where we find the wormholes and infinite possibilities. We might be able to see how the nature of duality, polarity, love, and compassion." Choose your own destiny" and love your neighbor" could be the exact manifestation of how "seeing isn't always believing, and believing isn't always seeing" exemplifies the faith and compassion as our collective(connected) human being view department of "the realm of infinite dualistic possibilities" commonly unknown as the paradoxical box wev packed ourselves in, under the ego/pride of our build a brain workshop thats uncommonly sensed as the the "creative/creator subconscious" that operates out of the infinite possibilities of "be careful what you wish for" and "honesty is the best policy" generated perpetually by the endless amount of "things that can hold you back", or "stunt your growth" like questions without an answer or clarity in the process of learning to understand the nature of ourselves and how we choose to act on our relationship with ourselves in terms of absolute truth that expands our paradoxed connection to all infinitely possible thought box paradoxes of the course to "manifesting our entire destiny" through attraction by our willingness to let go of anything that isn't rooted in unconditional love and compassion when weighing matters of the heart, we understand the nature of growth dualistic to the duality of infinite possibilities transcends us into the realm of endless possibilities that lies just outside of the thoughts we box ourselves into, in terms of the grand scheme of things pertaining to absolute universal truth and clarity of what weighs us down and what we choose to believe. As Above, so Below. As Within, so Without. (Duality, Polarity, unconditional love, and compassion) perpetually applicable to absolute truth and clarity.. ask and you shall receive. Seek and you shall find

[Superator]

This video actually didn't explain any science behind wormholes it only very briefly mentioned negative energy. Is negative energy "dark matter" or "anti matter" and if so how can it be produced to open a wormhole and how can it be sustained inside a wormhole while traveling through it???

[KaliFissure]

What ifwormholes are SUPPOSED to be unstable?
