Maybe nothing means -"without space, energy,matter or time present" my opinion is different. Time and space may not be present, but something that might not be accessible by us today would have been there before the big bang. Maybe a dimension different from what we can understand. Because we know that the universe is expanding. It is said that at the time of the big bang, space and time was instantaneously created. There's no big bang happening now but still more and more space is occupying the "nothing" as universe expands. So there should be something else that can be measured by some unknown dimension that keeps converting into space and maybe vice versa. I might be wrong, but i believe that's the only way to explain this.

One answer leading to another heavier question. And where will it all end? Just like the universe. We know the universe is expanding. But to "where" or to "what"? Started from a point so small, growing and growing each moment. Maybe we humans are bound to laws and properties so much that it restricts our thinking. Knowing lesser may have been the secret of great thinkers like Da Vinci, Einstein, Newton..... . Who knows....

You mean... the ray of light will make a loop?

Okay, equations may tell us that time started with the big bang. But , it's only true when we think of time with respect to all the "happenings" following big bang. and most importantly what triggered the big bang?

But there should be some scientifically known facts and theories right.. ? Isn't there any way we can find what existed before the big bang, if there was any. I agree. But why? Maybe the most difficult question science faces is just the word "why". But there's one thing we should remind ourselves. Maybe 5-6 hundred years ago, we didn't have any idea about antimatter,black holes and all that stuff... But we do know something now..

We have made certain scales to help ourselves with measurements. If we make that relative, then what's the point in having one? Or have i misunderstood your question?

A very good idea. But to build a robot which can build homes and all would not be a quick job. It won't be easy.

Meditation is the key. It has been proven that meditation can lower heart rates to dangerously low levels in extreme cases. To increase heart beat, all that is needed is a shot of adrenaline. You can think do it by thinking of something that can do the job for you.

From my knowledge, light cannot exist with zero velocity. But yes, it has to come down to zero velocity inside a black hole. Or what will happen to all the beams of light that get sucked inside a black hole? So which one would be true? Inside a black hole, if there's no time, then light can travel only in 3 dimensions.That means, movement with no time running. Is that possible?

t=c??? can you explain? t=c??? can you explain?

First of all, you need to know what makes mass. It has been proposed that Higgs -Boson(the so called God particle) is responsible for giving mass to any object. And gravity is thought to be a force that is made by the interaction of gravitons. Although these particles are not identified experimentally, recently there were experiment data from CERN giving heavy clues to the existence of Higgs Bosons. You can find more about Gravitons and Higgs Bosons in Wikipedia.

But for light, and inside a black hole, there exist no time. Isn't that right?

I recently saw 'Stephen Hawking special- Did God create the universe? ' , a program in the Discovery channel. The great mind concluded that he believes there's no god, and before the big bang, there was no space or time to begin any creation. And that everything was made from "nothing". So i was thinking, okay, there may not be a God, but what was this "nothing"? If the Big Bang started from an atom sized thing, how did it appear in the first place? If space is not "nothing", then what is it? For those who want to watch the program, search the title in youtube. Thanks in advance

Thank you . But i have this doubt . Anything that is pulled by gravity gets accelerated. And for different masses, there are different constant values of acceleration by which all objects, regardless of their mass gets accelerated. So wouldn't light too? I know the answer might be no coz . .there's no proof to prove otherwise. But i want to know why it doesn't.

If gravity is a force acting between anything that has mass, why does gravity from black holes pull in light (photons) which have no mass at all? And even if we consider light as a particle and not a wave, any particle with a finite mass needs infinite energy to accelerate to light speed. And one more thing. If gravity can pull in light, what happens to a beam of light coming towards a black hole? Would it accelerate due to gravity? And would light break its own top speed?
