With the VISIR instrument on ESO's Very Large Telescope, astronomers
have mapped the disc around a star more massive than the Sun. The very
extended and flared disc most likely contains enough gas and dust to
spawn planets. It provides the rare opportunity to witness the

The speed limit is the speed of light. And the change of speed limit
is below this. Otherwise if you could change your speed in a light speed
acceleration you would reach light speed.
Velocity and acceleration are related and both are limited.

I was wondering what would happen in the following (hypothetical)
scenario:
Say there is an extremely massive planet with person A on it and
person B is in a spaceship outside of its gravity field. (The planet

Why are "spacetime" diagrams drawn downside up?
If we're falling through the void, shouldn't our paths point downwards.
It's much easier then to visualize our galaxy going down the plug hole.
By the way, why don't the stars go around the galaxy at the right speed?

When light energy is emitted, Mass increases,: Einstein’s Sep.1905
derivation.
  It is not consistent prediction from Einstein’s Sep 1905

"Is There a Force of Gravity?"
    In undergraduate physics, the Newtonian concept of an attractive force
between masses that is proportional to the product of the masses divided by
the square of their separation is taught. When one advances to the more
