Hi guys, I'm curious about what happens when certain things happens, hence the name, "what if"
Anyways, it basically works like this. A user posts a "what if" statement. For example: What if the sun suddenly disappears.
Then other users will answer the what if statement.
For example, a user could say that everything will be dark without the sun. Then, as more people sees the statement, some would say that without the sun, we would get out of our solar system because the earth isn't attracted by the gravitational pull of the sun anymore. Then, some people could state that this is not true, and we still have a couple of minutes before earth goes around in the spiral because of the relationship of light and gravity.
This will go on an on, for about a week, until we "close" that statement, and go for another one.
Here are some rules (Posting a "what if" subject): 1. It must be related to science, and must at least point out a pretty nice discussion. ---Don't go on saying "what if my pants got lost"
2. Wait for a week before posting another subject.
Here are some rules (posting about the answer): 1. Link to your source. So we know you aren't lying. 2. Don't Spam 3. Follow AGs rules.
What if the plates on earth started breaking apart quickly?
Seeing as that is naturally impossible, I wouldn't know. But what I do know is that the Earth may collapse and break apart, life would die out and Earth would be comets again.
You mean the tectonic plates? Earth wouldn't shatter to pieces (and if it would do, the pieces would probably just attract each other) - given it's huge quantities of magma, earth might just turn into a magma ball.
Have you any link to that presumed post-melting ice age? I mean, if the polar icecaps melt, then under influence of a raised temperature, and the cold water would maybe just cool global temperature a bit. One of the consequences though would be raising sea level and shrinking land mass, maybe even flooding of smaller islands.
the sun will not dissapear suddenly for this reason.
Stars are born, stars grow old, stars die! The life cycle of a star is actually a struggle between gravity and gas pressure, which is known as the equilibrium. Majority of the life of a star is spent in a stage known as the main sequence. Stars fuse hydrogen, and when the hydrogen fuel is gone, they fuse helium into carbon.
A star is a sizzling mass of gas. It is composed of the inner core housing the process of fusion and an outer gaseous shell. The core is hot and dense, serving as the gravitational center of a star. The outer shell, made of hydrogen and helium, facilitates the transfer of heat from the core of the star to its surface. Light and heat energy is released into space from the surface of the star.
Life Cycle of a Star Stars are born in the nebulae, which are huge clouds of gas and dust. The matter contained in the nebula determines the mass of the star. The clouds of gas and dust disintegrate under the force of gravity. Gravitational forces make the nebula spin. As it spins faster, a âprotostarâ is born. It attains a temperature of about 15,000,000 °C. Nuclear fusion occurs and it begins to glow. The star contracts and becomes stable. It is now called the main sequence star. Stable stars exhibit the condition of equilibrium. Equilibrium is achieved when the force pushing out from the center equals the gravitational force that pulls the atoms inward. A gradual contraction is seen in the stars. With this contraction, temperature, density, and pressure at the core continue to rise high. The temperature at the core of the star slowly rises because the star emits energy, while it is also contracting. Hydrogen gets converted into helium by the process of nuclear fusion. When the hydrogen in the core depletes, the core loses stability and begins to contract. Outer layers expand and become less bright. It starts glowing red. The star is in the red giant phase. The life cycle path taken by a star after this phase depends on its mass. It will become a neutron star, a black dwarf or a black hole. In case of a medium sized star, the remnant hydrogen gas in its outer shell forms a ring around the core, which is referred to as the planetary nebula. Due to the gravity, the last of the star matter collapses inward. The matter is dense and compact, emitting white-hot light. This marks the âwhite dwarfâ stage in the life cycle of a star. After the depletion of all the energy, the star enters a âdark dwarfâ stage. A massive star in a red giant phase undergoes a different life cycle path. The fusion causes the helium atoms to form carbon atoms. They are further pulled together due to gravity, which results in the formation of oxygen, nitrogen and finally iron atoms. Iron starts absorbing energy that leads to an explosion. During this stage in the life cycle of a star, it is known as the neutron star. A neutron star might spin speedily giving off light and X-rays. The spinning star appears to be pulsing. Hence it has got the name âPulsarâ. If the core of the star still remains as huge as before, and there is no nuclear fusion, the star gets swallowed by its own gravity to become a black hole. This stage marks the end of the starâs life cycle.
1. all coastal areas are submerged, inland areas flooded --> global economic collapse --> roits and civil wars --> new dark age.
2. all coastal areas are submerged, inland areas flooded --> loss of biodiversity --> mass extinction.
3. all coastal areas are submerged, inland areas floodedd --> human migration to higher lands --> riots and relief efforts --> extremely slow and tedious recovery.
4. all coastal areas are submerged, inland areas flooded --> resources become scarce --> war for resource control --> nuclear war --> human extinction.
5. all coastal areas are submerged, inland areas flooded --> resources become scarce --> war for resource control --> grave loss --> settlement reached --> centralisation of administration --> extremely slow and tedious recovery.
Not very scientific but perhaps, some of the above events are probable and many are evident even today.
P.S: - Is there going to be a week-long discussion on a single topic? If so, I suggest you pin-point the topic for discussion, SecretMapper.
