for some reason even though ive pondered and tried to think about the universe a lot this short just made me understand gravity more with his explanation of saying Gravity may not actually even be a real force. Its just a name to describe a phenomenon we see when entities of physical mass are taking up space in the non-physical entity that is space itself. Then combined with the fabric concept and imagining that in a 3-dimensional perspective kind of wraps it up nicely.

So that’s why we don’t fall down we wrapped in a invisible blanket

'Time' is only a concern for living creatures.
'Gravity' coalescences stuff.
Space is merely where stuff exists .

[MegaSkills]

All of the accumulated knowledge of mankind (Including the contributions of Einstein) are just a tip of the iceberg of the facts of the universe we are yet to learn.Think about that for a minute. Most of it is still hidden. That is what makes Science exciting.

Love his t-shirt.. Isla Nublar Research Team.. from Jurassic Park?

[Johnny-sjsj]

Love this man, and I'm not even gay! It might have something to do with the fact that I've heard him and seen him speak in person, and that my one of my sons is his doppelgänger!

My late grandad use to say. We are like lobsters at the bottom of a 7 mile thin ocean! As Humans we will never be able to truly fully comprehend the true nature of the universe.

[Jaskanwar_Singh]

This would mean that there is a fourth dimension or maybe even infinite number of dimensions that humans have not yet discovered. (In theory)

[emoji_page]

Maybe they should come up with a better name for it than gravity. Space/time dimples? Space/time fabric pot holes?

[virtualworlds]

I always had the idea that the universe was a sphere that we`re inside, 3d if you like, I always struggled with flat universe theory.

[ngoma]

What is the "fabric" of space made up of?

[christopheraaron]

That's the reason why we can't unify electromagnetism weak and strong nuclear forces with gravity because gravity is nothing more than a distortion in space

[charliehall]

Does a black hole have aa front or back, or a top and bottom???

[supanovasky]

It would be amazing if we had a camera that could see photons, microwaves, radio waves, neutrinos, to see how they travel. In space. I see all these particles travelling like a coiled spring that has spin, not a wave But viewed from the side it looks like a wave.

[mbobedominic]

In simple terms, the universe, as we know it, has contour lines.. there are invisible mountains and trenches within the universe. Some trenches are so deep that light can not escape.

[milesfurnell]

We think about this in the wrong way. Objects don't move through space. Instead, the components of the fabric of spacetime conserve the momentum and manifest the energy of the waves that cause fluctuations as they pass through, similar to the way pixels on a screen manifest the electromagnetic energy of certain voltages, creating the illusion of things moving on the screen. Gravity is the effect created by adjacent components interacting, creating a pull on the fabric.

[MarcelPereiraHouston]

Exactly, the units of gravity are not units of force.

[TheWorld]

Reaction to the environment probably sums it up

[James-bvnu]

If gravity is not a force, then there is no force.

[mhwse]

Just imagin if we could influence the directional vectors of the time/space vectors themselves, without using gravity - or the other way round, "before" the big bang - there were no such directional vectors .. (as there was no time too) - yes that is prohibited, because of causality. But there must be a kind of "storage" where this information can be found.
This information prohibits then, that all other information can spread with unlimited speed. That is what Einstain says, from an other perspective.
