Well, eventually the sun is supposed to explode and take Earth with it or so I hear. But that's billions of years from now, so we may be living on other planets by then lol. Either way, if we lose the earth, we lose all life on it as well.

Talking in science terms, it is a matter of time that the sun will burn out one day, when that happens, Earth will not have sunlight, thus, the plants cannot photosynthesis as there is no sunlight, one of the conditions in order for the plants to photosynthesis, when the plants cannot photosynthesis, they cannot make food, which means the food chain is broken, animals will not have their source of food, ultimately, the human race will not have food too and wipe out.

In another science perspective, in the Kepler's law, formerly known as Hubble's law, "If the universe is finite in extent and the cosmological principle (not to be confused with the cosmological constant) does not apply, and the expansion speed does not exceed the escape velocity, then the mutual gravitational attraction of all its matter will eventually cause it to contract. If entropy continues to increase in the contracting phase (see Ergodic hypothesis), the contraction would appear very different from the time reversal of the expansion. While the early universe was highly uniform, a contracting universe would become increasingly clumped. Eventually all matter would collapse into black holes, which would then coalesce producing a unified black hole or Big Crunch singularity.

The Hubble Constant measures the current state of expansion in the universe, and the strength of the gravitational force depends on the density and pressure of the matter and in the universe, or in other words, the critical density of the universe. If the density of the universe is greater than the critical density, then the strength of the gravitational force will stop the universe from expanding and the universe will collapse back on itself. Conversely, if the density of the universe is less than the critical density, the universe will continue to expand and the gravitational pull will not be enough to stop the universe from expanding. This scenario would result in the 'Big Freeze', where the universe cools as it expands and reaches a state of entropy.[1] Some theorize that the universe could collapse to the state where it began and then initiate another Big Bang, so in this way the universe would last forever, but would pass through phases of expansion (Big Bang) and contraction (Big Crunch)

Recent experimental evidence (namely the observation of distant supernova as standard candles, and the well-resolved mapping of the cosmic microwave background) has led to speculation that the expansion of the universe is not being slowed down by gravity but rather accelerating. However, since the nature of the dark energy that is postulated to drive the acceleration is unknown, it is still possible (though not observationally supported as of today) that it might eventually reverse sign and cause a collapse. Dark energy is, however, still a speculative theory." If that happens human race will also die out.

Thus, I conclude that the human race will die out

I don't think we will advance far enough to escape a supernova, other world ending event, or collapse of the Milky Way in to the black hole at the center. We are rejecting science in favor of opinion and consensus. Intelligence to group think.

Our sun is going to explode and before that the heat from it will be so strong we will be fried if we are still alive. For all we know in a few million years we could be hit by an astroid or another major event that will change the other orbit for better or worse

If human can survive a couple of billions of years until the Sun explodes, humans will have probably left to colonized a different planet.

Eventually the universe will come to and end, collapsing in on itself. The universe is finite. Life is finite.

Yes it will because of disasters like a quasars gamma ray hitting earth, the sun exploding , asteroids , huge super novas, and there might be a super volcano that erupts and creates a ice age were all humans die.Last ice age all but 5000 humans died.Before we make it to 3000 A.D and be supreim.

Absolutely. We have seen throughout historyu that species even ones more successful than ourselves have disappeared. But first we may evolve from what we are now to something more adapted to surviving in space. Habitat is one of the leading causes of evolution and I think it is inevitable that we will change, perhaps several times before our exsistence ends.

well we are extremely intelligent species but I don't think that means we are going to go on for eternity, even the universe has an end, as intelligent as we are we can find solutions to almost any problem so I think the biggest threat to humanity is... humanity. face it, the most likely way of dying is killing ourselves, and I honestly think in some ways humans are stupid enough to do that lol.its the way our governments and societies work, I mean come on we let the same retarded dumbass in office for eight years straight, as much as any president can get and look where we are now, in the middle of a war we never needed to be in. truth is for these societies to work humans have to make them work, and the best way to make sure that happens is to have some power over our society and all the strings planted around us humans to make it work, give the wrong person too much power and we fall like that.

actually u all are right end of the world is fixed either by the supernova or a blackhole

but it would take billion of years so we will be much advance by then so earth will end but not humanity

Nuclear War will cause the demise of the human race. Such a shame!
