Will intergalactic space travel and space habitation be possible within the next 1000 years?

Space is not empty. It is not a complete vacuum. Even between stars and galaxies there exists gasses and dust. In intergalactic space the material will be very diffuse. Also,...

A planet can get ejected from a solar system by the gravitational pull of its sun, another planet or another star passing through its solar system. There are problems with...

Intergalactic space (IGS) is near-absolute vacuum but not vacuum. The very hot hydrogen plasma in the void (one highly compressed and confined atom in a cubic meter) is highly conductive...

Gravity is a force that reduces its strength inverse square relation with distance..

The distances involved in intergalactic space travel would require some mechanism of Faster Than Light (FTL) travel to be accomplished in practical, useful time frames. Such mechanisms would tend to...

Einstein's theory of relativity states that nothing can travel faster than the speed of light. In fact for any object with mass it requires an infinite amount of energy to...

Given what we know about physics and space, it IS possible to travel from one galaxy to another. The impractical side is that anyone or living thing is not likely...

That is the temperature of cosmic micro wave radiation left over from Big bang.

Stars are about 5 to ,10 light years away from each other,But galaxies are millions of light years away from each other. The distance between Milky way and...

$(1/2)^(t/5730)(I)=A$ I = initial amount, A = current amount, t = years I=0.200g, A= 0.0125g, solve for t $(1/2)^(t/5730)(0.200)=0.0125$ $(1/2)^(t/5730)=0.625$ $log_(1/2)((1/2)^(t/5730))=log_(1/2)0.0625$ $t/5730=4$ $t=22920$
