Will scientists soon discover new dimensions?

We are used to the 4 dimensions of the world we perceive around us: length, width, height, and time. But, for more then a century, theoretical physicists have proposed more dimensions. During the time of Einstein, German mathematician Theodor Kaluza proposed that there were 5 dimensions. In the 1980’s this was expanded by String Theory to include a total of eleven dimensions. But, up until recently, there has been no way to test these theories.

Now, physicists are combining data from Japan’s KAGRA gravitational wave telescope, MIT’s Laser Interferometer Gravitational-Wave Observatory (LIGO), and the European Virgo interferometer. They think they may be on the cusp of observing the ‘breathing’ patterns of gravitational waves that could indicate more dimensions beyond our perceivable reality.

What is Gravity?

Gravity is something we all take for granted. We know that it is what keeps us firmly planted on the Earth, we can calculate how much force it takes to breakthrough into open space, and use it to predict the trajectory of baseballs or even meteors. But do we know what it is?

Actually, not really. We say that Gravity is a force of attraction that exists between any two masses. But what is that force? Is it made up of particles called gravitons which travel at the speed of light, as some physicists have proposed? This would make sense, and relate to the action we see in protons, but so far, no gravitons have been found.

Another theory is that gravity is changes in the 3-D geometry of spacetime. Like a bowling ball placed on a trampoline, objects with mass create depression that pull other objects towards them.

Still others put it down to something having to do with dark matter, mass that we know makes up the majority of the universe but we cannot see or detect through current instruments.

A new discovery in 2016 opened up as many questions as it answered when scientists observed gravitational waves for the first time.
But still there is no consensus as to what exactly gravity is, so what do you think is most likely?

What will first conact be like?

Mathematically, it seems inevitable to me that, given enough time combined with the number of planets in our galaxy that are hospitable to life, that we will meet aliens. Given our current exploits in space (our technology has left the solar system but not entered another, and physically we have not gone any further than the moon) it is unlikely that we will be the first ones to make contact with the inhabitants of another world. That means that more likely it will be them showing up on our door step, or calling on the phone through some interstellar messaging system.
So what will that event look like? we have seen them be the aggressor with examples like H.G. Wells 'War of the World' and us being the aggressor like in Steven Spielberg's 'E.T.' or James Cameron's 'Avatar.' Then there is a whole grey area in between, like in the movies 'Men in Black'.
So, what do you think first contact will be like?

New Planet. . .Same Problems?

Imagine, if you will, it is the year 2080. Earth lies in ruins after nearly a century of runaway climate change. As the seas rose, the ten largest megacities on the planet like New York, Tokyo, Mumbai Bangkok, and Buenos Aires had to be evacuated, as did entire island nations like the Maldives. These climate refugees then had to find somewhere else to live, in countries that did not want them. Suddenly, clashes of religion and ethnicity broke out and created World War III.

Those with the means built massive space ships and sailed to the nearest hospitable planet. Most of these ships were funded by the groups in control on earth, and thus where made up of single religions or ethnic groups. Now that they have arrived on this new planet, will they get along peacefully, or will the same problems they had on earth prevent success of our species in this new land.

Are we part of a binary star system?

Most of the stars in our galaxy are binary star systems, meaning that two suns are entrapped in each other’s gravity and maintain orbits around each other or a central location. Leading science today states that our sun on the other hand is a lone traveler through this Milky Way. But, could it be that we actually are in a binary star system? Could it just be that the two are so loosely entangled that the revolution takes millions of years, longer than human eyes have been observing?

Who would own Mars?

With Elon Musk gunning to build the first community on Mars, a good question keeps popping up. Who would own Mars? Even though Space X has worked with Nasa on certain projects, it is a privately owned company. If Space X landed on Mars first, what would stop Elon Musk from claiming Mars? This is a question that's for someone that is much smarter than me, but it seems like the answer would be in a murky gray area. What do you think?
