Some scientists say Venus might be a better option to colonize than Mars,since Venus has similar gravity to Earth,and high up in Venus' atmosphere,the atmospheric pressure is similar to Earth.Venus is significantly closer to the Earth than Mars. Temperatures high up in Venus's atmosphere are around 70 c(very hot,but manageable).On Mars,you would actually boil without a spacesuit or pressurized environment,since the boiling point of water becomes very low in low atmospheric pressure. Venus provides better shielding fro the sun's radiation.NASA is actually taking the idea of setting up colonies high up in Venus' atmosphere seriously.

The speed of light is about causality. The universe cannot exist if mass can accelerate faster than the speed of light. However,an object can travel faster than light if it's not accelerating faster than light. For example,the Earth is moving away from other regions of the universe at faster than the speed of light,because the universe is expanding faster than the speed of light,because space has no mass,therefore, the Earth is not accelerating faster than light,but is moving away from other regions of the universe at faster than light.

Scientists believe there may be such thing as a 'white hole' ,which is the opposite of a black hole,in that it ejects matter,but doesn't allow matter to go inside it. Some scientists believe the Big Bang was a white hole(which could ask the question of where ''where did the matter to create the big bang come from '' '? . Some scientists believe a white hole ejects the matter a black hole sucks up,or perhaps it ejects the matter from another universe.

Problem with both religion and science is our inability to not be able to understand a story without a beginning. Where did god Come from? Where did matter come from before the big bang? And when we answer something another question is raised where did this new thing come from?

And when we answer something another question is raised where did this new thing come from? One theory about how particles and matter came into existence out of nothing is the energy of a closed universe is zero,the energy of matter is positive,the energy of gravitation is negative,and they always add up to zero. Hence,creating a closed universe out of nothing does not violate any conservation laws. Some physicists believe there was only massless particles right after the big bang which always travelled at light speed,then something caused the particles to gain mass,which caused them to slow down(since mass is an impediment to motion),and mass is a property of matter.

I think it's incredible vanity for mankind to assume that we have any importance AT ALL in a universe so vast.

Possibilities for interstellar travel. By exploding nukes behind a starship,we could achieve 10% the speed of light,and since the nearest Star System is 4 light years away,at 10% th e speed of light,it would take 40 years to reach Alpha Centauri,BUT,the starship would need to slow down,which means halving the speed,which would mean the trip would take 90 years,and would need multiple generations of humans living on board. The WAIT calculation comes into things,because there's no point launching something within 20 years,if something we launch after 50 years overtakes it.

Scientists believe there may be such thing as a 'white hole' ,which is the opposite of a black hole,in that it ejects matter and light,but doesn't allow matter or light to go inside it. Some scientists believe a white hole ejects the matter a black hole sucks up,or perhaps it ejects the matter from another universe. Dallas County Commissioner and all around racist John Wiley Price would agree. m.youtube.com/watch?v=oc1zGRUPztcLOL John Wiley Price calling that guy a 'white hole' is actually a complement since a white hole ejects useful matter,where as a black hole only sucks everything up.

Here are some reasons as to why some scientists say time might be an illusion,which is why scientists like to use the term 'frame of reference' when talking about time dilation.
An article about whether there was time,matter or space before the Big Bang.

In a way I see little value in wondering what happened before the Big Bang. It's impossible to observe, much like trying to see 'beyond light' to see what the universe is expanding into. Rather we need to focus all of our efforts onto how to terraform and travel to other planets. We know our time with the Sun is limited and that one day, even if its millions of years in the future, it's gonna come to an end. If we're not gonna go with it we've got to find a way to travel among the stars. String Theory is nice and all but FTL travel and warping just don't fit into a model of physics that works for our squishy, fleshy bodies or our metallic space ships. Gravity is what we need to focus on. Time in space has shown us that deadly radiation and low gravity will put a premature halt on ANY extra-solar travel we attempt so that's what we need to be working on right now. If we can manage to unlock artificial gravity and radiation shielding then we can finally be ready to take our first baby steps out into the galaxy... and maybe one day beyond.

Yes,it's inevitable our Earth faces destruction from when the Sun expands,or even sooner from a whole range of things that could happen. We consume and pollute so much,that we will need to find other planets to consume,until we change our habitual nature. If we could control gravity,we could warp space so we don't need to focus on accelerating at fast speeds,especially since no object with mass can accelerate faster than the speed of light . Since the universe is expanding at faster than the speed of light because space has no mass,in theory we could use gravity to distort space to bring 2 points closer together. In theory,the stronger the gravitational field,the more we can bend space.

Is the Moon in Majora’s Mask a Black Hole?For the moon near Termina to cause the rock's on Termina to levitate,the moon near Termina would need to have a density billions of times more than Earth's moon.
