Crossable Wormholes? 

Beware, a little mistake has crept into my animations at 4:42. The light ray should not have been drawn as if it was "reflected" by the white hole. It should just have escaped from within the horizon. In fact, because it is an extension of a black hole's geometry, the white hole is still attractive, it draws things in, towards its center just like any other object. The difference is that nothing can ever reach its horizon. This is because the white hole is technically in "the past". So, because we can only travel towards the future, its impossible to go through it.

"We didn't like the way the math initially told us the hole would form, so we made the math tell us another way"

This channel is so underrated. This is million subscriber content right here.

I don't understand how such a high quality video has so few views. This is excellent content, sir, truly! Edit: This comment was posted 8 months ago when the video only had a few thousand views. I'm glad to see that it has gained some of the attention that it deserves.

1000x the better explanation than a documentary on cosmos

If a wormhole couldn't bring us beyond it's time of creation, is it essentially a time checkpoint that human could travel back to at the end of the world

8:13 The fact that you're so close to a huge gravity generator ensures that, even if it only takes a few days to cross the wormhole, thousands of years have passed for everyone else.

This channel deserves more recognition for its quality

I am going through a period of depression these days, but your videos are so beautiful and stimulating they save my sanity by transporting me to a higher plane. Like looking at a starry sky (can't see many in London). Thank you.

This was amazing. You seamlessly combined concepts that other RU-vid videos cover during multiple videos, yet you did it in 15 minutes, and in a vivid, easy to understand way. Loved it!

Best channel for scientific phenomenon so far... Hats off to the creators.

I landed on this video while executing my 10 minutes daily random video views. 1) I am blown away by the quality of the video: script, science content, graphical representation and animations. 2) There's a perfect balance between advanced concepts and simple explanations, context and good use of examples. Super happy, discovered a pearl. Fairly certain that this channel will explode with millions of subscribers... Also, by reading the comments, I'm super happy that the viewers are also surprised by the video quality and channel content, meaning that we all have similar quality threshold Made my day!

This content is fantastic! Feels like "In a Nutshell" mixed with the delivery of "Ahoy". So concise and easy to receive, props man!

! GOD. The Quality of these videos... You have a Patreon or something? Somewhere I can donate??

I've watched this dudes videos 4 times already. This is my go to science Channel. I love so much. Thank you for explaining physics to us dumbs.

The quality of this video was incredible. You are literally the best educational RU-vid channel I have ever come across. If you keep this up, gret things are coming!

Am a fan of science and especially theoretical physics, in fact, I have been so since my childhood, I saw thousands and thousands of sophisticated well made videos and documentaries, but this, this is a whole different level, to simplify all these complicated ideas and pack them in 15 min, that's a high-quality work 👌✨ "simplicity"

Love the channel. Makes complex concepts much easier to understand. I’ve always struggled with understanding quantum mechanics but your videos have really helped me grasp that and many other concepts. You deserve more recognition. Keep up the great work

Truly high quality content, animation, narration and explanation of phenomenon! Well done!

Holy shit! I didn't realize how few subscribers and views this channel has until I looked at the comments. Wow. This is some professional content here! subbed and liked^^

Extremely good and clear explanations of very tough themes, really glad, that youtube showed me this channel.

I predict that this channel would grow exponentially in the near Future

Your graphics are amazing! Really helps me grasp the concepts.

I love this channel. You guys explain everything so well.

Remember the good ol’ days when we thought this world was “normal”?

Imagine trying to cross a wormhole and getting trapped in a hellish nightmare for a quintillion years.

All those fancy documentaries that i have ever seen related to space or physiscs , not a single one of them could match the videos of this channel in terms of quality and details

Beautiful. Thank you so much for creating this.

What a content, even If one doesn't know a thing about laws of relativity, he/she can find interesting stuffs throughout the video. Excellent work, keep working on your good works.

People watching in 2400:

This is my new favorite channel! Thank you so much for all your amazing videos! ❤

I like how you always bring up the formulas for everything

Amazing quality! Good visual representation can do wonders for education. Thanks a lot!

I like how you waited to near the end to drop the bomb that general relativity is not perfect.

Gawd I love your content :) Thanks for such bad-ass videos. Legitimately original man ... this is the first time I've ever even seen a video about wormhole geometry and whether or not they can feasibly be crossed. Really fxk'n interesting :)

Chill narration, great animation.

Aside from other factors being mentioned in the video, if the space inside the wormhole is being stretched outwards from its center in order for it to exist in a valid/cross-able form, wouldn't that make, things that go through , possible to be ripped apart *depending* on the force needed to have it opened the first place and sustained?

This is one of my fav channel Your doing a great work. Thankyou for your efforts that made us to understand quickly 💓💓

Brilliant video, black holes, worm holes and time dilation are some things I could talk about for hours and not get bored of it, fascinating.

A truly superb work. Thank you.

I love how spacetime is represented as a 3D fabric field rather than a 2D plane. It can be misleading to younger children to think that there is fixed direction in gravity.

Wow excellent videos! I can definitely see this channel blowing up

At the time of writing this comment, I can see this channel has less than 140k subs. That's just criminal! You deserve a million plus, no question. Honestly, you're probably the best source for hi quality science explanations of topics that can get very confusing, very quickly! Hats off to everyone involved. 👏👏👏

This is what i needed from longer time but don't know why it is underrated he explained very well

Another great video. Would love to see your treatment of potential shapes of the universe, since I've never been able to understand that, and I bet you'd do a great job. One side comment: you mention that quantum physics applies to microscopic stuff. It's funny people always say that, because electromagnetic waves can be the size of the Earth or bigger.

After taking a ton of math classes in college, I feel like I sort of understand now 🤯🤯🤯🤯

I loved your work. Very well explained .

I would like to ask you the next time you put a mathematical equation to mention the meaning of its parts and components, that would help a lot in understanding the philosophy of "why" and "how". thank you, u deserve respect for this excellent work.

you explained gravity... with gravity great

I always find it fascinating that we as humans don't have our scientific curiosity as our number one priority, or else videos like this would be at a billion views.

This channel explaining so intuitive

This was really neat. Did you cover the other two types of wormholes displayed in this video ever?

5:06 but would that be a whole or simply spacetime expanding everywhere equally? Kinda like what our universe does?

I suddenly feel *almost* smart!

Badass videos without even asking people to like or subscribe.. you know they will!

Great video ScienceClic English and I like your videos so much :]

Now that's some real science, well done professor

I think there is some misconception that gives a lot of people mistaken idea of mass = gravity (higgs = graviton) when saying because of it's mass it distort the space time around it ( 0:45 ) , from what I understood after searchig for Higgs - graviton differences, it's the energy not the mass distorting the space-time, photons that are massless can also have gravity fields around them. Also theoretically a blackhole from photons can exist. Correct me if I'm wrong but that what I came out after searching for higgs - graviton correlation

Phenomenal work! This explain much more than the scientific theories.

This is some genius work… thank you for your hard work!

12:50 the siri on mac has this switching manifold lol

*_so it's possible that Spore is perfectly canon?_*

The gravitational lensing of blackholes, white holes and wormholes look so pretty. It's like an extraterrestrial magnifying glass floating in space. It looks almost magical and majestic as you can see the stars behind bend and transition behind it.

way of presentation is super awesome. excellent explanation of all topics 👌👌

Wondering how you'd re-imagine this video with your new GR visualization in mind

When people start making up mathematical "possibilities" it ceases to be science and becomes wishful thinking. Still, it's interesting, and a fertile ground for science fiction.

This is the first time I have heard fourthly, also the quality of this is unbelievable

These are the kind of videos I enjoy. You did your research

I don't understand how this channel doesn't have atleast 1million subs yet

this channel is underrated!

darn. really underrated channel

You seem to know exactly what I don't quite manage to understand from other videos and show exactly what I need to get it right. There's some information about a lot of things in my head, somewhat out of place or with missing connections, and you're videos just put them in the right order, connect them together.

Some Physicians (i think) think that wormholes using exotic matter, which have a negative mass. Am I saying false things that make no sense or you didn't take that in consideration? Although, thanks for the beautiful and very instructive video.

I had a dream about this happening once and the way to get through the hole is two make a black hole made of a positive energy source and a black hole made of antimatter. Then push them together and it almost instantly resets time in the region of space and the hole is distilled at a time that is not toward or backwards

0:31 the best graphic description of the fabric of space warped by gravity I've seen.

Man you deserve WAY more subs and views The algorithm really hate you

Black holes are solid spheres of mass, not holes in ¨spacetime¨...

12:51 Siri is just a string theory

This videos are insane, wow. Do you also have a video that talks about the "multiverse"? That would be amazing!!😍

Some really amazing sci-com 💛🌟⚡️

I dont think that you wuld end up anywhere near a galaxy if you would exit (as radiation^^) a white whole...because it's a white whole xD Maybe it is because of that that they can not be seen - because light cant show it to es either...it bounces away in all directions, so there cant be light hitting us directly. The spot pointing directly at us would be infinite small. MAYBE...oof...this could be black matter. This is why it can not be detected...it pushes galaxies away from each other, because they can only exist between galaxies. They cant be detected, because spycetime is only pointing away from them. So even if you try to look at it, the light you see was bounced and comes from somewhere else... (like a good magigician - doesnt matter how hard you try to look where he exchanges cards, he always fools you to look somewhere else) I feel smart right now, but I am probably totally wrong xD

"our universe"

Well information. Good show.

Commenting for the algorithm! Such masterpieces need to be heard by more people!

imagine if my parents looked at things like these and not chakra and astrology bullshit

It’s weird how sometimes you say something, and then you say the exact same thing a few seconds later with a different tone.

An amazing video again!

I love how logically everything is explained here 🌟

Thank you for this amazing content

Great content. Amazing voice over.

You sir, have just earned yourself +1 sub for quality content.

How are you making these??? This channel is amazing.

Very informative!

excelent animation and explanation

thank you im so glad that i got the sceince behind white holes this is great work

Great video!

1:07 i love your video. To improve it: the background grid is shone as if it is dilating around the black hole. I feel it would be contracting. I could be misunderstanding. Thank you.

Grandiloquent but informative narration.

Fantastic video.

your graphics was Insane 💥✌️
