I'm not a genius nor a scientist, but something about what you say is profoundly wrong.
I need to watch that train ride video again.
Even in space to propel something there's an equal and opposite reaction. So things do not have zero mass. Some theoreticians once thought (back
before the space age) that it would be impossible to propel a spacecraft in a vacuum because there was nothing for the propellant to push against.
That same kind of pseudo-theorizing is what you're doing. I've done it myself, so I'm guilty too. The answer is to learn. I suggest to read more
physics books and watch some videos. Educate your mind.
But I'll admit that I don't UNDERSTAND most of this. If Einstein was trying to lie then I'd eat it up because I can't even grasp what's supposed to be
the lie. In order for Einstein and others to create a lie of this scale they would have to be amazingly intelligent, beyond 99.9999999999% of humans
or better. That's in the billions I think. I think it would really only work if Einstein was an alien.
So I get what random is saying, but I don't think Einstein was THAT smart. Others would get it. And I don't think they could all keep the secret. Not
for long. Nothing stays secret for long.
For an example of somethign that confuses me... is.... if you're traveling near the speed of light and emit a beam of light ahead of you, it will
appear to travel at the speed of light. This boggles my mind. The only thing I can think is it has something to do with time changing and creating the
illusion. Otherwise, I'd be led to believe that it's traveling faster than the speed of light because my speed and its speed are added. Which is not
the case. They're not added, yet the illusion remains.
Another thing that confuses me is how do we know our true absolute speed when traveling through space? We calculate our speed in relative terms. For
example, relative to our sun, our orbital speed is X. If our sun is rotating around a cluster of neighboring stars then the orbital speed of our sun
is X. Ultimately, we're rotating around the center of our galaxy and this speed can be calculated. However, our galaxy is rotating around something
else, perhaps a cluster of galaxies. And these galaxies, in turn, are rotating around something else. And this goes on and on. My question is where
does it end? From my understanding, we don't know the true size of the universe. We only have guesses. If we don't know the size of the universe then
how can we calculate our absolute speed traveling through space? We need to compare ourselves to something else to find the speed, but if the size of
the universe is unknown is signficantly larger than us then how will we find our absolute orbital speed? Locally, the sun is our orbital speed. But
what is our absolute orbital speed? It's somewhere...
For all I know, we're traveling around the largest mass at 1mph but traveling around a galaxy cluster at 500000000mph. Does everything in the universe
orbit a single center of mass? Seeing how we orbit the sun and it ultimately orbits hte galaxy and hte galaxy ultimately orbits the largest mass
outside our region of space (wherever that's)... it would seem that the universe would have a largest center of mass just like a galaxy would. Take
the whole universe and put it in an image and zoome out until you see the largest center of mass and then imagine all of it orbiting that.
