comment How can electrostatic forces provide lift to the gossamer spider?
I mean more specifically in the context of what we are talking about, not about a piece of paper under a charged balloon, we are talking about lifting to 4km.

comment How can electrostatic forces provide lift to the gossamer spider?
Are you saying that a suitably charged and light piece of paper can lift upwards just based upon the charge?

comment How can electrostatic forces provide lift to the gossamer spider?
What I mean is that if its true, then why can't we then create a charged object which can do the same or a device which can float upwards based upon electric charge (not ionic wind).

comment How can electrostatic forces provide lift to the gossamer spider?
It doesn't explain to me how a charged object can generate a lift, it says there is a electric field in the atmosphere, it says the spider silk is charged, but thats not an explanation about how it generates lift. If you accept that as an explanation then you accept a poor explanation. I've never heard of a charged object able to then float up to 4km in the atmosphere.

comment Why is the observable universe so big?
Note that your only referring to the observable universe, not the actual universe size. The actual universe size could be much much bigger than 80 billion light years across. The fraction that we can observe is smaller than the actual size.

comment Is it possible to project a magnetic field at a location in space?
billions, trillions, of optical tweezers all over the bottom of a spin stabilized object

comment Is it possible to project a magnetic field at a location in space?
Could powerful lasers pointed up at some object scale up the optical tweezers effect by creating millions of optical tweezers, lift an object upwards?
