wow thats not a reply i expected , top info there guys , nice...
so light isnt constant? and not the fastest form of travel?

Anyhow i keep thinking about if two twins etc parted, one stayed one went far lol they,d age differently ? I understand time being warped , spacetime itself is warped due to massive gravitional forces produced by us, the planets, our star the sun.

i get lost at worm holes , is this a result of blackhole etc?

cheers for response
