How can a Black Hole warp space when Space is nothing?

Question

The question may sound silly ,but..everyone is always saying Space is not Tangible,.or has no mass,.but how can something with no mass,.be effected by Gravity/./?

Answer 1

Think about a 2-d grid.

If you went up to it and bent the y-axis, then you would be bending "space" even if nothing is in it.

Answer 2

But space IS something. It's the medium that all matter and energy moves through. Also, black holes don't just warp space, they warp time as well. It sounds strange but when you start to really study BH's, you'll find some pretty weird things that they are capable of doing. I know my answer is rather short, but there is WAY too much to say about BH's to give a short response except that BH's are, in my opinion, the most interesting feature that our universe has to offer.
I hope this helps. Good luck.

Answer 3

properly, the simplest thank you to commence is to ask the question, how compact could a large physique be to confirm that the get away speed from that physique be extra beneficial than the fee of sunshine? you need to use Newtonian gravity for this and get clsoe to the appropriate effect: GMm/r >= a million/2mc^2 --> r <= 2GM/c^2 So put in the mass of our solar a million.989x10^30 kg and G = 6.67x10^-11 Nt-m^2/kg^2 and get r = 2.8 km. this fee of the radius is termed the Schwarschild radius. Now the solar has a radius of 6.96x10^5 km so it can not seize gentle. If a action picture star is large adequate, then while lots of the hydrogen and helium are used up in fusion, the beginning up can not generate adequate warmth to maintain the gases around it from collapsing using gravity. that's at that component the place the problem could be pulled right into a ball whose radius is smaller than the Schwarschild radius at which component the action picture star will become a black hollow. Now from an area-time view component, lots reason area-time to twist. once you get a black hollow, area-time is curved very strongly, so strongly that the jobs of area and time "substitute" as one enters the black hollow. Now we don't see this immediately, we see a boundary called an experience horizon the place evidently that some thing falling right into a black hollow maintains to be continuously. What we are seeing is gentle trapped at that boundary. So on on your question - the wapring doens't reason the black hollow - that's any incorrect way around. area, extra wisely area-time, is empty different than for be counted and power. Warping manifests itself as gravity - right this is a thank you to think of of it. think of of a mass sitting in area-time as a ball sitting interior the backside of a bowl. Now the steepness of the partitions of the bowl are based on the mass of the ball -the extra large the ball, the steeper the partitions of the bowl. The partitions signify the curvature of area-time. The steepness represents what we call gravity - that's purely the curvature around a mass, and we could stick to the curvature. The rigidity we experience is by using how immediately the curvature variations as we pass in direction of or faraway from the mass - that's called a gradient. interior the Newtonian approximation, the rigidity is going like a million/r^2 the place r is the gap you're from teh center of the mass. And gravity comes from the urvature of area-time using be counted or enery.

Answer 4

Space contains matter and time. A photon is mass less but it follows the curvature of space. It's like catch 22.

Answer 5

Lets follow this scenario if space is "nothing ",then it can be concluded that "nothing" warps. And "nothing "curves including time. Space time would become =nothing time.And relativistically determining gravity would meam that "nothing "Curves in the presence of mass."
What you refer as space being untangible is what Einstein called imponderable substance.
This imponderable substance was referred by Einstein in His lecture at the Universeity of Leipzig in 1920,as The" Aether"

Answer 6

Here are some questions for you to think about:

How is it possible to bend light using a mirror?

What happens to light from a distant star as it passes a large planet or another star?

What happens to a falling object if the ground is constantly curving away from the falling object? ( I know this is more Newtonian, but it helps to visualize geodesics)

And finally check out Einstein's theories on relativity and gravity

Answer 7

space isnt tangable, but its there. our brains just cant really comprehend that matter and energy isnt everything, and that the space it all fits into is actually something to. and space isnt affected by gravity, your confused. space, in a way, is gravity. gravity is how matter warps space. so gravity effects matter, it doesnt effect space.

Answer 8

its not about the lack of mass.. aka space
its about the laws of physics and how its affected

Answer 9

there is dark mater in space.
