General Relativity is not an easy concept. Combined with the fact that space/time exists independent of time and space outside of space/time, you get an accurate solution to cosmic events but a counter intuitive explanation of the expanding universe. The common view is that space/time is a bubble of existence that began at the big bang. As the bubble expands everything inside the bubble moves apart with the speed of expansion plus whatever is happening locally. This combination of speed and distance allows for objects to travel much faster than the speed of light while being held to the speed limit of light in local space/time. A similar event occurs at the event horizon of a black hole. General Relativity allows for space/time to be distorted (sucked into) a black hole's gravity well at speeds in excess of the speed of light. So if a particle of light (photon) is traveling out from the black hole but space/time is falling into the black hole at or above the speed of light, the photon can never escape making the hole black. The event horizon is the point of distance from the gravity source where space/time distortion equals the speed of light. Light, being a massless particle is not directly affected by the pull of gravity, only the distortion of space/time. Indeed. I've looked at the field equations, and they are waaay above my understanding of maths. Even the first paper is difficult because it is so counterintuitive. |

Please...
Let there be no more Math.

Please... Let there be no more Math. well,lets replace the Dielectric on the Flux-Capacitor then!

I bet that'll use more Gigga Watts, though.

You must really mess with Cashers at the check-out, Moe.
Technically, the face-value of the shirt still stands at $98 Dollars, because the Purchaser hasn't surrendered that one extra Buck to either or his parents. So, if he'd of given each of his parent $1.50 back, and he didn't keep any of the change... He'd still owe $97 Dollars. Thus, the question can be made $1.50 + $1.50 + $97 = $100. |

I am not sure, some believe there are portals. For instance I was living in an old house on one day in the summer the screen door opened and a little girl in a strange dress old fashioned came in and was startled at seeing me like i was a ghost and she ran upstairs. I found out I was staying in her room and her brush was there and had hairds on it as if she had brushed her hair.
My grandmother was a SEER on the reservation and saw the past, present and future, it is an old word for prophet. I have her gift and so does some of my kids. My daughter, very young was waiting with me for my now ex husband when married to him. We saw a van come up with him wearing a different pair of glasses and saw people say he was teaching a class. My daughter and I almost went in the van but my watch brand new watch stopped and I felt the danger do not go in the van with him! Then we say a shimmer and he came walking at present time but would drive the van and wear the new glasses years later.... experienced other very odd things of time travel type things... and researched them too. who knows? I love the One Step Beyond Documentaries. |

Of course it is and it's already been done!

Einstein had some interesting thoughts of it.

rethinking the math.... http://news.nationalgeographic.com/news/2014/01/140127-black-hole-stephen-hawking-firewall-space-astronomy/ http://phys.org/news/2015-01-black-holes-space-theory.html http://www.nature.com/news/2005/050328/full/news050328-8.html No one has disproved Einstein's General Theory Of Relativity. On the contrary, it has been verified in every possible way. The papers you quote are more fringe science than science and philosophical than scientific. In the real world (or universe actually) we have found that supermassive black holes are at the center of all major galaxies. Saying, for example, that the event horizon of each black hole cannot be accurately determined therefore the black hole doesn't exist is silly since the black holes do, in fact, exist. Their mass can be calculated. Their positions accurately charted and sometime they can be visually observed if they happen to be having a meal. If Einstein's equations concerning gravity's effect on time work everywhere else, we don't need much of a reach to apply those rules to the black hole also. The physics that don't work are at the center of the black hole (the singularity). The equations of gravity mostly all include dividing by the radius distance from the calculated point to the center of gravity, which in this case is zero distant. Dividing by zero doesn't work in math so the formulas blow up. It's really that simple. |

sure come back in a year find this topic again.. and it will seem as though... no time has passed at all..lol

Eat magic mushrooms for a week and you'll know time travel is real?

Now....this is smart.

Okay Conrad...
I'm going to pull a Homer Simpson here. I want my Black Hole with extra Ice Cream and Sprinkles !
