The ever expanding Universe; can we discover it all?

Could humans discover the whole universe?

The universe may be expanding at the speed of light or faster, but scientists claim that the universe could stop this.

This would be due to the amount of space pollution.

However, if space pollution stopped, the universe could still die out anyway due to heat.

But would humans live to discover it all? And could we discover it in time?

That is a question I have wondered for a while.

We could discover the whole universe because:

  • We have been beginning to find solutions for things (like electric rockets) to help stop space pollution. However, at the rate it has been happening, we may not find a solution in time and then we can get to the very tip of the universe.
  • Technology is advancing, and we could invent a rocket powerful enough that it could travel against the speed of light and reach the end. (This is very unlikely, however, it is possible.)
  • There may be another problem in space that we do not know of which could stop the growth of the universe.

We cannot discover the whole universe because:

  • It is growing at the speed of light or faster; technology is very unlikely to be able to beat this pace of 186282 miles per second.
  • Humans have not travelled far from Earth yet; as the universe could be destroyed by the time we develop the correct things to reach there, it would cease to exist.
  • The universe could have it's own ways of keeping it expanding, meaning that it could be impossible to reach the end of the universe.

I believe that humans will not be able to discover the whole of the universe as the chances of things being able to reach that far at all are very slim. Necessary vitamins and minerals which are needed in human bodies could not be found meaning the they could die before arrival.

What do you think?

Thank you for reading!

    I don't think this would be possible because:we will not have enough resources to travel that far,oxygen supplies will be limited and rockets will not stand the heat. ( good post)

    I agree, happy_politics. Since we have travelled little distance away from Earth, the chances of humankind reaching the end of the universe before it dies out is extremely slim. The technology we have created cannot reach that distance. Unless a rocket is filled with enough fuel, it will freely float. To reach out of our own solar system, we would need to guide the rocket. This would use up most (if not, all) of the fuel we can load into the rocket, meaning that the rocket may not be able to make the journey back into the Earth's atmosphere.

      Can we think of any other reasons why humans might not reach the 'end' of the universe?

      I agree with you awesome_vegetable, the chances of reaching the end of the universe before it dies out are extremely slim. Although, I disagree with you on the point you made about how the current technologies we have, will not allow us to reach 'the end of the universe.' You are looking at what we currently have but who knows, maybe in a decade we could have bio rockets with plasma shields, which could go to the outer limits of existence. Free_hedgehog says that without proper fuel supplies we have no chance of even reaching our nearest galaxy, let alone the edge of the universe! I think that if we have access to solar panels which are able to use energy from light which is billions of light years away, then we are set to send robots to the outer limits... We have to be able to guide and control our rocket which is quadrillions of light years away says Mr. Hedgehog, how are we going to send data from that distance to Earth? Why should we send robots to the outer edge of our universe, costing us trillions of pounds... and that mission has a good chance of failing. 3o trillion pounds put to waste?!!!!

    I strongly agree awesome vegetable because the universe expands at 74.3 plus or minus 2.1 kilometres (46.2 plus or minus 1.3 miles) per second per megaparsec (a megaparsec being about 3 million light-years). This is incredibly fast, we have discovered less than 5 percent of the universe, that 5 percent being the observable universe, that being 93 billion light years across, that number is getting bigger all the time. It would take us over 40 billion years to reach the end of the universe if we beat the explanation rate of the universe and the universe is predicted to die in, according to one theory, 5.8 billion years, there are many other predictions but none come close to 40 billion years. As awesome vegetable has said, we will not have enough fuel. Unless we use a reliable and renewable source of energy. Even if we do run out of fuel on the mission then we would still be carried along by our own velocity for a period of time but the rockets will not beat the explanation of the universe.

    As I said, I strongly believe that it is impossible to reach the end of the universe.

    The local group is the area in which humans are trapped due to the increasing speed and growth of the universe. It is about 50,000,000 (50 million) light-years across and consists of the Milky Way, Andromeda and about 50 dwarf galaxies. It is only a small section of the Laniakea supercluster, which is only one of many in the Observable universe. Although the local group is huge, it is only 0.00000000001% of the Observable universe (and thats no exaggeration). We are trapped in this bubble FOREVER, whether we like it or not.

    I agree with you happy_politics. It would be very difficult if not impossible to travel to the end of the universe as there is no end of the universe (because it is expanding at the speed of light).
    I don’t think that space junk could have an impact on the universe expanding because scientists have recently calculated that the momentum that the Big Bang created is stronger than the force pulling it back (gravity). The amount of space junk is nothing compared to the total mass of the universe meaning that it would have no impact on whether or not the universe still expands at the speed of light.
