Say if I was to factor x^2+2x-1 and I used the quadratic equation and I end up with 1 plus or minus i square root of 3 over 2. So if that's simplified its 1/2 Plus or minus 1/2 i square root of three. This answer is complete arbitrary but why is like i(square root of 3) over 2 = to 1/2 i square root 3. It is it because there's always a 1 infront of square root 3?

LED light bulb works on forwar bias and off on reverse bias. Are we simply let the negative part of the AC current go wasted (as it can not light up the bulb) or we rectify it (the negative AC) to continue lighting up the bulb? If the negative part of the current is not use, will the LED light bulb flicker like the florescent light?

Universe infinite etc;

Although we haven’t proved at this moment universe is finite or infinite; based on all current physics and scientific principles it has to be infinite. It is impossible to imagine something to end without something beginning. If universe ends at some point something has to be there after that. Otherwise it cannot end. Period.

People come out with all these 4 dimension or 5 dimensions. But so far no scientific basis for these dimensions. It is just imagination. No body can explain what are these dimensions. Science so far has explained only up to 3 dimensions. I really do not understand this more than 3 dimensions. So far none of our physics related principles could explain what is 4th or 5th dimension. Science and physics are facts. Nothing imaginary there. I doubt there can be anything like 4th or 5th dimension of universe which can produce a finiteness of this universe. Based on all scientific thinking so far universe cannot end it has be infinite and continuous. It cannot have a center. It cannot have a beginning or ends. Things might change time to time, new galaxies, stars etc form etc etc but the whole universe will always be same.

It is possible a sub compartment of the universe had an explosion of mass. And this mass was very huge to start with. The mass was so huge and made up of fire like our sun or stars. This mass was billion and billion of light years in size. So huge and unimaginable for our estimation. It exploded one fine moment. It was so huge that the pieces of it produced all the galaxies and everything we see in the observable space today. After explosion it is spreading now in all directions. This is what we see now as big bang. It really doesn’t make any sense to think that big bang started as a small point. Everything is possible who knows ? we haven’t proved anything. But it is easier to explain scientifically a large mass exploded for some reasons and the pieces of this mass went in all directions and the momentum produced by the explosion was so huge that the pieces are moving away from each other still. It might have occurred several billion years ago and pieces are still moving away from each other.

This theory has another advantage to accept. When we talk about how solar system was formed this is what we talk. A large fire ball, the parent of sun, all 9 planets and all other solar system members ( comets, asteroids etc etc etc ) exploded which produced Sun and other members of the solar system. When solar system parent exploded there was a main piece remained to form Sun and all the planets etc started rotating. When, how solar system was formed we talk about a huge mass exploded which produced several solar systems ( star systems ). In other words a huge galaxy like mass exploded producing several star systems. But when we talk about how universe was formed we talk about a small pin point area produced it?? It doesn’t make sense. Why not similar to formation of galaxy system, solar system etc, it is the bigger mass exploded producing all we see around.

But when the Huge mass described above ( parent mass of the observable universe ) exploded probably no residual big chunk was left in the center and that may explain why we do not see any residual big mass around which everything what we see rotates. The same thing could have happened if while solar system parent mass exploded if no big chunk left to form our sun all the scattered mass would have been moving away from each other like a big bang observation ( they would have moved away until hit another star or pulled by the gravity of another galaxy system )

I do not believe in curved universe etc. People give example of balloon expanding. When give analogies it should make perfect sense. The problem with balloon analogy is ; the balloon actually expands into the surrounding region. So how can we use this analogy for universe expanding. I agree all points on the balloon go away from each other while balloon expands but balloon still expands into surrounding area, agree? So universe must be expanding into surrounding area, means there is space out side this expanding observable universe. Can somebody give an example where balloon expands also doesn’t expand into surrounding space??? No body agree? Balloon expands is equivalent to it spreads into the surrounding place.

Means if universe expands it automatically is spreading into the area out side its spreading edge. Otherwise it doesn’t maker any sense.

Another analogy given: earth has no edges. Universe is similar to earth without edges. It is finite because of this. People start walking on the surface of a circular object like earth and make comments like earth has no edges. Does it make any sense?? Why we go on the surface to find edge?? Why don’t move into the surrounding atmosphere or away from earth‘s surface ?? Everywhere earth has edges. The moment earth ends the surrounding atmosphere begins. A circular object will have edges all over its periphery. Unlike a rectangle etc.

Universe curves on itself??? What exactly it means??? Why does it curve?? Can it curve unless something outside it??

Looking from any angle if we use our current physics and scientific knowledge, theories and principles Universe has to be Infinite. We come out with all explanations to prove it is finite but no explanation can be accepted so far as none of them make any sense. Just hell-bent on proving universe is finite we are coming out with all analogies which have no meaning at all.

Probably the big bang observation confused everybody. Suddenly scientists didn’t know what to do? How to explain the findings? Then they came out with some explanation.

And they are telling the whole observable universe started at one point. A small point. Is it really possible? ( well I agree we haven’t proved it is wrong, but based on science and physics we cannot accept such statements as one small point exploding and giving rise to much much bigger mass like galaxy and stars which are much much bigger than the original small point itself. That is against our existing scientific principles.

My point is should we really accept this big bang theory??? Is it the only theory which could explain the observation that all galaxies are moving away from each other?? Don’t we have any other explanation??

How about logical or scientific explanation like a huge mass exploded and scattered all around and the force was such that they are all still moving away from each other and from the center of explosion?? This is similar to the existing big bang theory the difference is the size of the initial mass which exploded. With the revised big bang theory the initial mass was huge and its mass = to the collective mass of all the mass of the expanding observable universe so physics principles are not bent. It is difficult to imagine a small point producing all these mass in the observable universe. We need to come out with something new to prove this. Everything is possible when we don’t know about something.

It is possible once the force reduces these galaxies will stop moving and then collapse and return to the center and produce the original parent mass of the expanding universe again. I think then again it might explode. This process may be repeating once in every billion billion years who knows?

It is possible in the infinite universe infinite number such huge masses exist and they periodically undergo this type of explosion and then collapse and the cycle continues. It is possible the distance between such huge parent mass is such that probably the expanding sub compartments of universe probably will never collide with each other in general. Some of them might collide against each other. We know that some galaxies collide, some do not, so that should not surprise us.

A small point exploding and a huge mass exploding both can explain what we see happening now. What we see is everything moving away from each other. But it is easier to explain a huge mass exploded producing all the observable universe rather than a small point exploding. This is contradicting the existing scientific theories. It is a story like or imaginary stuff good for a kids movie.

I strongly believe universe is infinite. Of course if we don’t know then we don’t know. For me it is easier to believe universe is infinite rather than finite based on existing scientific principles, that is all.

I tend to believe that theories in science that are well tested and predict experimental data well are unfathomanble facts of the universe.
For example, evolution, general theory of relativity, quantum mechanics are all undeniable facts of the universe, and its futile to try and prove them wrong.

I also believe that everything in the universe is understanble through science.

Who agrees with me? disagrees with me? who thinks that there are things that happen that scientists can answer?

As you can see, science is my religion...
