Are we living beings going to be destroyed in about 10000 years time?  | | I have a greatinterest readig the online science magazines.i recently read an article about a giant back hole present inside a galaxy located just 2.5 billion light years away from us.the artivle specialises in gamma ray bursts and goes on to say that this black hole is the most massive one in the whole observable universe.although 2.5 billion light years is very far off distance, it is not much far awaya as for as very high energy bursts are concerned.it would have been better for us if such a monster massive black hole was present more than 8 billion light years away. but there it is and we cannot do anything about it.the article goes on to say that another smaller galaxy with a much less black hole is situated near this galaxy.both these galaxies sem to be on collisionn course and scientists expect the worst to happen in the event of collision. that collision was to take place in about 10000 years from now.but since the galaxies are situated 2.5 billion light years away, they could have collided by now and the gamma rays sent out.the sun and earth are located in line with that galaxy's orientation. so the gamma rays are predicted to reach the solar system and earth too,in 10000 years time.these gamma rays could cause all the destruction they can. we have to wait and see what damage they are going to do .if we already have dangers from asteriods and comets here on earth, this gamma ray thing is something unwanted .moreoever, this gamma rays could travel ad arrive at earth much faster than we expect! what an excitement we have in store!

Pose123 (5746) | 3 months ago | Hi golvine, The majority of scientists seem to believe that the earth will around for a few billion years yet, and I expect will outlive the human race. While the things you mention may be possible, the only thing we know with certainty is that the earth as we know it will someday be no more.Blessings.

golvine (207) | 4 weeks ago | have you heard of the news a few days ago at yaho news that a small asteriod about 7 meters in size passed very close to the earth . it may not sound nice for us.these close events are going to happen every year.anyway not many of us will last no more than 120 years on this earth as we age out! so generally it matters little to us if the earth survives for billions of years . we have to live with the earth for so long, individually each of us, if we are to see that happen . can we?

A very large comet has been observed for more than 30 years to be on a trajectory course towards the solar system. It will pass close to Earth. The theory is that this will cause the Earth to be turned upside down. The dust from the comet will cover the earth for at least one day, completely blocking sunlight. Changes will occur.
It is only a theory, but it should not be completely dismissed.

| | 3. borg246 (150) | 3 days ago | Us people, here on earth, we depend a lot on energy. We all know that we get our energy from burning fuels. We get our fuels from underneath the ground derived from coal/ oil/ methane and more. Oils/ coal and such materials, here on earth can be found underneath the ground but how did they form? All forms fuels contain the chemical Carbon and all living organisms have carbon inside their bodies. Therefore, one can say that these materials are made up of millions of years old of dead animals all decomposed and mixed together with other mineral found here on earth. How did those animals live? Those animals lived off other animals but how did the other animals live? They lived off eating plants. How did plants live? Plants live by producing their own food by photosynthesis from the...SUN. Therefore, we rely on the sun for all our energy needs. All forms of fuel here on earth, were created with the help of the sun. We can even see this in solar panels and the condensation of water from the sea to produce rain.
The universe is made up of several galaxies all joined up together. Each galaxy is made up of several solar systems all placed together. Each solar system is made up of a Sun and their planets such as our Sun, earth, mars, venus, pluto, uranus, jupiter, neptune etc.
Each Sun that we find here in the universe is made up of stars put together. Each star is made of tiny molecules of debree roaming around space combined with hydrogen. The Sun is made up of millions of stars and it is made completley out of Hydrogen, that's why our sun produces energy in the form of light and heat.
The life-expectency of each sun is calculated by the amount of hydrogen molecules (H2) that there are left in the sun. Over time, these Hydrogen molecules turn into Helium molecules (He) which turn the sun back into dust. This slow process knocks off years of life-expectency from the sun.
Each sun has an approximate life-expectency of 14,000,000 years. However, scientists were able to observe the quick decaying of Hydrogen molecules turning into Helium molecules and have concluded that from 2005 upwards, we have at least 7,000,000 years left until the sun dissapears. Since here on earth, we depend on the sun for our energy, when the sun is gone, we won't have access to that energy and therefore most of us living organisms, animals and humans will die. One must also know that all of our food is made from plants and plants live from sunlight and when that is gone, everything will be gone.
So, one can conclude that we have at lease 7,000,000 before we are surely going to become extinct, however, I do also believe that within 100 years something is going to happen to this earth because of melting ice caps, global warming, pollution, green house effect etc, but our race will not be extinguished, it will just be a reformation of the earth.
And to conclude: Are we living beings going to be destroyed in about 10000 years time? ---> No.

golvine (207) | 1 day ago | There are many worldly causes for mass extinctions.i just wanted to explain the cosmic causes of extinction that can happen.the sun cannot provide all the energy we need . it is useful to prevent us from freezing to death.it also saves atleast 14 hours of power by providing free daylight for us.the sun is a living proof that life on earth is not going to last for ever. we will be destroyed even while the sun is there. a safe and stable milky way galaxy is a safe solar system.most other galaxies are not as safe and quiet as ours.the advantage for us is, things are not happening here in our area of galaxy as they are happening in other parts of our galaxy and beyond.our solar noighbourhood has been extremely quiet for a long time and nothing big has happened.so far it is good for us.but a supernova explosion in our neighbourhood will be enough to send hot matter and gamma rays to the solar system. the hot matter will take just 500 years to reach the solar system and boil everything in our vicinity.no matter ca travel with the velocity of light but even if the supernova matter can travel at 1000 km per second it will be enough for it to reach us.
