Is it possible to see electrons?

Question

According to the theory of relativity, the relative mass of an object increases as its velocity increases. Does that mean it is possible to see an electron with the naked eye if it is accelerated to just below light speed?

Answer 1

The mass of an object does not determine the Size and Shape of an Object.  The smallest Black hole is atleast 3 solar masses (3 times the mass of the sun), but you still cannot see it.

Just because it has a large mass doesn't mean it is visible by the naked eye.

Answer 2

with increasing speed mass increases does not mean size increases  

Answer 3

Err why would relativity allow you to 'see' electrons.

We can see the photons electrons give off when they drop down an energy level.

(delta)E=hf

where h is a constant and f the frequency of the photon. Photons interact with your retina to which allow you to see. Hence you 'see' electrons all the time.

Indervidaully no, it's impossible. But we can 'sense' electrons based on their charge with machines to 'see if they are there or not'.
