Space travel is the biggest fucking meme ever. Its just a wet dream for aspies and gay 60s sci fi writers.
We are literally surrounded by endless space and are forever bound within Neptunes orbit by hard laws of energy and matter.
People think that our world is like civilization 5 where technology is just research points that unlock after a set number of years but it's not. We've already discovered the purest form of energy in the world, nuclear fusion, the energy that powers stars, and it's still not even close to enough energy it would take for interstellar travel, or to create a wormhole or something. And antimatter is a meme tier propulsion method that requires much much more energy input to make the antimatter than you get from the antimatter itself, simple conservation of energy principles.
So far the fastest thing we've ever made, the new Horizons probe travels a velocity of 58,536 km/h (36,373 mph).
Do the maths. To travel 10 light years in 100 years you'd be travelling at 10% the speed of light indefinitely from the moment you leave earth to the moment of arrival. This is roughly 3 million miles per second.
Do the maths. 3,000,000 x 60 = 180,000,000 miles per minute. Multiply that by 60 to give you a miles per hour figure, 10,800,000,000 miles per hour (10 billion + 800 million) and that's just ten percent of the speed of light. To get a mere 10 light years at this utterly impossible speed would take 100 years.
Now remember that you don't measure the universe in light years, you measure it millions of light years. Now do you begin to see the problems with actually travelling in the universe? Even getting from Earth to Mars, practically nothing in galactic terms, would take all our skill and ingenuity.
Getting outside the solar system is basically impossible and ultra-wealthy clowns like Elon Musk either a) know this and are conning the general public or b) utterly deluded richboy fantasists.
