3 Ways Black Holes Could Break Physics

What if the Earth were swallowed by a black hole? Would humanity’s legacy be gone forever? Or could you somehow get back that information from behind the event horizon?

There are three possible answers to this question...but they all break physics as we know it!

An example of disappearing information (energy) is when the lasagna recipe is burned in your fireplace. The information is altered and lost forever.

[LordGalenYT]

Information is not energy. Information is the specific arrangement of matter and energy. If the arrangement is changed, the information is destroyed, but the matter and energy are not. The destruction of information is completely within the laws of physics, we just tend to define information incorrectly.

[youyou-wcvv]

maybe time really goes backwards for the informations escaping the black holes, so it returns to it's original state, so a time loop is created, that's a real paradox

[Dan-bqrd]

On a UNrelated note I always wondered if you instantly teleport somewhere would you go back in time like for example if you were instantly warped through space You would get there faster than light relative to you

[ApophaticCartesian]

Could you do a video on Magnetospheric Eternally Collapsing Objects(an alternative to the black hole) and why its not accepted by mainstream physics even though its passed peer review several times?

[priyanshugaur]

Wow ! Finally, Thanks for the video. Nobody can explain like you do. You are cool.

Is the information really lost if all the atoms gave off gravitational waves just as they pass the event horizon?

[nuggetjimenez]

Or since the black hole is so dense the gravity is super strong and every thing sucked in it is just compressed a lot. No laws broken

[aaaazzzzable]

I'm a simpleton, but wouldn't everything just be transformed? I always thought a blackhole was like a giant blender and everything within it would be vaporized and turned into it's absolutely most base physical/theoretical form. Basically grinding everything down into atoms then grinding those atoms down then continuing to grind and transform the energy within into something totally unsalvageable.

Like a quasar is the point were light and heat are the most intense, that bright inner ring around a blackhole. Wouldn't whatever reaction be trumped by the fact that everything will be caught in that circle of heat burning millions/billions of degrees? Even being near that level of heat and radiation would render everything completely toast, right? Information would be irrelevant.

[cartoonvandal]

If a singularity is tightly structured and rigid point with only a
limiyed number of states, why don't black holes decrease entrophy in the
Universe as they swallow matter? Wouldn't this be a violation of the
2nd law of thermodynamics? I'm trying to understand heat death.

it's impossible to get back in time .., the black hole are limited circle ... in unlimited space . and if it is not limited so we have new space inside our actual space here !!

The binary code video clip at 3:26 had a 1, a 0, but weirdly a 9 and a 2

[hbkjnhbjk]

I don't understand. If you go faster than light and go at the past. How can you change it?

[usamasoomro]

There is a physica girl's video about energy not being always conserved ... maybe 3 is the answer ?

[pablo-koky]

Hi Greg, You guys need to stop telling people that beyond the speed of light you return to the past. This is an impossibility. Since it is theoretically possible to travel beyond the speed of light, when this is accomplished one does not go back in time, one goes into future time, or put more correctly, one goes into a different time.

[patrickhavens]

I don’t think it’d be lost forever because of conservation of energy but I do think it’d be lost beyond recognition after the black hole radiates it off

[timver]

Wait, if a light can't escape a black hole, isn't the black hole's gravity faster than light. If it sucked you in, wouldn't you travel faster than light, making that not happen in the first place?

[blar-blar]

What I think is that the black hole will rip apart the earth and and the info is turned into heat and the earth gets made into gamma rays.

My hypothesis that Dark Matter is not a WIMP, but maybe is a deformation of space-time by which the curvature of space-time ALONE is the cause of the gravitational effect. Gravity is the consequence of the curvature of space-time. It may be possible that the structure of space-time itself could be warped without the presence of mass. Space-time has been shown to react like a fabric by warping, twisting, and propagating independent of mass. These properties have been proven with observations of gravitational lensing, frame dragging, and now gravitational waves. Fabrics can be stretched, pressured, and/or heated to the point of deformation. Such extreme conditions were all present during inflation, so it is plausible that space-time’s elastic nature could have hit its yield point and permanently deformed. Therefore, if gravity is the consequence of the warping of space-time, and fabrics can be permanently deformed, then a deformation could create a gravitational effect independent of mass. Thus, the unidentified dark "matter" that seems to be so elusive to modern science may not be matter at all but merely warped deformities causing gravitational effects. DM could be a microscopic black hole with no mass at the center...
Prediction: Spacetime's elastic property hits a yield point, so only that part of geodesic's "stretch marks" would remain after inflation stopped. These steep gravitational wells would not follow the inverse square law. I am looking for Theorists or Experimentalists to help me develop ways to test this hypothesis. Is there a way observationally to test it’s gravity does not follow the inverse square law?

may be information travels faster than light as math predict tachyons does.this could also explains quantum entanglement as einstein says 'spooky action at a distance'
