1,2- According to Physicists, Spacetime is curved and is constantly Expanding. Even If We Travelled With Enough Speed, We can End Up Where We Started.
3- There are lots of Galaxies, Stars, Quasars, Blackholes, Supernovas, etc.
4- According to Scientist There Are Atleast 60 million Earth like Planets in Our Galaxy Alone And There Are more that 100 Billion Galaxies in the Universe.
