That is one major misconception. The big bang was not an explosion. It was just spreading of matter and space. Though the singularity it started from was infinitely hot and dense, something caused it to expand but it did not explode.
Oh Yeah U R Right But Do U Think Due To This Expansion The Universe Will End In A Great Freeze??

There are several hypothesis about how the universe would end. The great freeze sounds the most logical. There is also another one that says that dark matter would grow and force all matter into a singularity. And the singularity would expand again after some time to form the universe (big crunch). But I would go for the big freeze.

You are still telling what other told you. Tell me how you measured or calculated it yourself, and how you finally reached conclusion.
Your statement is not quite logical. In science we constantly stand on the shoulders of giants and great scientific findings. He can't make all the findings himself but he can read articles from trustworthy sites and journals. Or do you think Faraday would have invented electricity if he did not study and trust sir Humphrey work? But faith gives no room to new and innovative research since it claim to have all the answers which in reality it does not.

Wow But The Two Could Still Happen They Is A Possibility Lemme Stress My Brain On It

The two can't happen. In the big freeze, the universe would continue to expand until the degenerate era and the energy in the universe would reduce. Stars would die slowly and no new star would be born then in the dark era only corpse of stars would remain like black holes, neutron star, etc and the black holes would all evaporate following Hawkins radiation. Then all the particles would disintegrate. This may take as long as 10 94 years. As the universe would go to an almost 0 energy level. And the universe die forever.

But in the big crunch, as dark matter push matter into a singularity the universe gets hotter that even a supernova compared to it would be chilly. Stars would melt like was. After the singularity is formed, it begins to expand after some time to form the universe. So it's more like a cycle between big crunch and big bang. We might be in the 1,000,000,000,000 cycle now. Who knows

Isn't science about fact? So there are many things you were told about science but don't really know how they actually work. But you have to accept them dogmatically. If they can understand them, why can't you? I didn't say he should do the findings himself, but he should at least be able to tell what he understands about the discoveries. Because , the so called scientific facts in astronomy are speculations based on calculations, they are not fact at all.

They say light is moving 300000 km/s did you just believe that without questioning how they arrived to that conclusion? Or yo actually know h
The speed of light yourself. You said "they are trustworthy" they are not! The people who faked moon laning are not trustworthy.

Please what sort of life would survive and thrive without the sun and how?

I do agree with him on a basic level, there are some lifeforms that survive independantly of the sun in the deepest of the oceans, they get their energy from hydrothermal vents in the ocean floor...so those kind of life could probably survive and evolve to adapt to the change in geography.

it is the knowledge of these life-forms that have driven scientists to find out more about europa and its ocean and the high possibility of life thriving there from some form of geo-thermal energy source instead of the sun

I would assume you havent killed someone before with a gun(if you have, more grace to your elbows).

If i asked you to take a gun, point it at your mother and shoot, would you?

why wouldn't you try it out?

you havent shot a gun before

you cant just believe what they say about guns without trying it yourself nah, can you?

I Don't Think Any life Will Survive At All Cause Heat Energy Cannot Be Used By Autotrophs To Make Food Hence The Use full Energy That Enters The Ecosystem At The Start Of A Food Chain Is Considered As Lost When It Is Changed Into Heat Therefore The Flow Of Energy Is In One Direction In A Food Chain This Means That The Ecosystem Must Receive A Constant Supply Of Energy To Keep Its Biotic Community Alive And This Outside Energy Source Is The Sun Without The Suns Energy All Life On Earth Would Cease..
No Sun = Plants Die
plants Die = Primary Consumer Die
primary Consumer Die = Secondary Consumer Die

Your analogy is dumb. If I hadn't seen gun before and someone told me that gun killed. I had to believe him, because he told me based on the experience he might have had about the gun. Perhaps he used it himself or it was used in his presence. He didn't just assume that gun killed because he had dream that gun killed.

The reverse is the case here. They said "earth is rotating around the sun 67000 mph." though, they never saw earth rotation. just speculations. How come when we jump up on the moving earth we land on the same spot? The said if you threw something up inside the moving car, it wouldn't fall down far behind you. Is something moving straight compared to rotating object? We asked, "what makes earth rotate" they said gravity. They can't really explain how the so called force of gravity. They just assume it pulls everything down. And the only example they gave is that if you threw something up it would fall down. Why the so called gravity allowed me to throw something up in the first place? The same gravity can't pull smoke down. If the Sun's gravity is constantly pulling planets toward it, why hasn't the Earth been pulled into the Sun?

The law of gravity pull the to the earth to the sun can easily be broken whe a bird flies. They gave another excuse that gravity is the strongest and the weakest force. What make gravity strong and weak? Gravity remains unproven theory not fact at all. And if the gravity is removed in astronomy, what is left is zero.

Baba, before you start making excuses and trying to disprove facts or scientific hypothesis(yes there are lots of hypothesis) you should get your facts straight. Science is not an alternative to religion, everyone in the world can be regarded as scientists, as we all share the characteristics of curiosity, even in the bible and quran, there are several cases of people finding solutions to problems, those are two crucial parts of our science, science doesn't need faith, like you're asking if gravity is real or not, gravity is a phenomenon we haven't fully understood, but then there's hardly anything we have been able to fully understand. Gravity is fact, I'm quite sure that if during the time the bible was written, gravity had been observed, there would have been an explanation for it for the benefit of people who refuse to reason for themselves.
You follow the calender which says 28 days make a month, why haven't you questioned that?
Let me do a favour and answer that question about when you jump up and land on the same spot... You land on the same spot on earth's crust not space, if you could hang a ball in space which isn't attached to earth, you'll see it occurring at different parts on the earth's surface, then you'll assume it is the ball moving.
In fact as much as I try to understand or answer your question, the more I see how dumb it is, before you start disproving anything, ma
ke sure you learn all you need to know about it, don't just read half a line and start making creepy idealisms

Eddygourdo:
many million years ago, the meterites that brought the seas , plus the mega volcanic eruption that caused the world to freeze up , killed all life forms existent then. Yet we have humans today and other animals. This haappened because lifeforms adapted at microbial level. And lived throughout in the ice, just as we would discover on mars very soon. When the earth began to unfreeze. The microbial lifeforms true to natural laws of natural selection and genetic mutation started to evolve from these differnet microbial lifeforms existent in those areas to suit the environment. The microbes evovled over millions of years into the diverse animals and plant life you see today. Everytime the world faced a catstrophe like the type which wiped off the dinosaurs, life will return to adaptive microbial forms in a dormant state till conditions improve to allow regeneration again. Current human life and animals will all be wiped off in any catstrophe as that has happened more than 100times since the existence of our solar system.

Anymorre questions sire ?

Of course, mankind CAN'T survive, although many cretins will have more than enough time to post their usual trivial nonsense on nairaland as GOODBYE....

If that happens (as physically impossible as it is), the earth would still remain warm for a few million years... but since we dwell on its surface, we're certain to experience the effects much more sooner...

David Stevenson, a professor of planatery science at the California Institute of Technology, United States, explained that within a week, the average global surface temperature would drop below 0°F, and in a year would have dropped to -100°... The top layers of the oceans would freeze over and the ice above would insulate the water below and prevent the entire ocean from freezing solid for hundreds of thousands of years... and after millions of years our planet would have reached a temperature at which the heat radiating from its core would equal the heat that it radiates into space...

Only microorganisms living in the Earth's crust would survive the post-sun existence.... most life's gonna perish... an immediate end comes to photosynthesis, hence the death of most plants in just a few weeks... plants are the bottom tier of the food chain, and with their ends, animals would die off, and that includes HUMANS of course!

Well we would live till the oxygen runs out or the cold overpowers our feeble bodies.. in any-case.. death is a sure thing, small groups might be able to survive a bit longer that others though given the right access to crops grown with simulated sunlight and oxygen probably prepared from artificial means..

ok.. so Uhm, not to be off topic, but i thought i should bring it to everyones notice about a new social platform created by a Nigerian that could potntially rival the big boys in a lot of features... need i say more, head over to www.greenhouze.xyz
