Einstein’s general theory of relativity suggests that our universe is finite but lacking a boundary or outer edge. Huh ? No comment..lol

@Laughman Something we might never know the answer to

@usher I agree on that. I also think we will never find other life forms out there to communicate with. We have barely left the solar system (voyager). Thats the equivalent of stepping onto the first blade of grass on a turn farm.

@Laughman Agreed, but at least we have the imagination to travel anywhere..lol

@usher exactly..I think its awesome. I'm not sure if I will see a human mission to Mars in my time, but I think we will get there one day.

@Laughman I think it might happen soon, as there is a bit of a space race between Elon Must, Nasa and the Chinese. Nothing like competition to change the game

@usher yeah I've been watching that a little bit. I just don't know how they would go about it. Plus I think it might only be a 1 way trip.

@Laughman Mars at it closest is around 7 months, so i guess the first trip might be just endurance to see if it's possible for humans to make round trip. After that it will be a better opportunity.

@usher yep it would be a mammoth effort. The supplies, communication food, water, mental wellbeing etc. And look whilst we are out there we could pop over to Jupiter as well !

@Laughman My guess is maybe in around 200 years or so we'll succeed. We just need faster rockets

@usher I think a key thing will also be the need to have a station outside Earth orbit to commence the journey from. Getting a rocket off the earth's surface and into space is half the battle - and half the fuel.

@Laughman good point, and there are some believe that we have a new propellant called bending space as claimed by bob lazar who say that alien technology is already being used. Bending space might not be as unbelievable as we might think as it's already part of some physics curriculums in universities

@usher I'll put my hand up and say I know nothing of this stuff. So this might be a stupid question - is that similar to the space bending example shown in the movie event Horizon? Ie 2 points on a piece of paper and bend them so they physically touch to create the shortest distance between a and b?

@Laughman I don't think so , that film portrayed space being bent as in a wormhole. The space bending in rocket propelling is not actually bending space the same way as a wormhole. It creates a void in space where the rocket moves into because of the void. In this way it creates a void in reality and so not causing any effects of velocity on the pilot. Bob Lazar explains it better, but he is accused on being a fraud and charlatan.

@usher that's interesting to visualise. I basically understand the idea. Not sure how you would control your destination/ arrival point though.

@Laughman An energy is generated using the Element 115 (it has only been made artificially in small amounts)and where ever the energy is pointed causes space to 'bend' . It's highly theoretical but the USA is accused as having a large quantity of it and may have experimented with this propulsion system already. The future is almost scarily unpredictable
