comment Why are there more vertical takeoff than horizontal for spacecrafts?
Yes, but they couldn't do it successfully, which is why it is only recently beginning to work.

comment Energy and Matter
I really think this needs to go to Physics - especially with the imminent demise of Astronomy. The physics guys would be able to give very straightforward answers on the interchangeability of energy and matter.

comment What is behind the cosmological horizon barrier?
Just checked your profile and realised you certainly know the maths in much greater depth than I - so I am more than happy to believe that 2 is more likely :-)

comment What is behind the cosmological horizon barrier?
Option 1 or 2 both seem more likely than 3. The tricky thing is that the models could allow any of them to be true. Inflation can work as viewed for option 1 as easily as option 2.

comment Can you damage your eyes viewing Venus?
Additionally, the OP probably only felt like they had arc-eye as their eyes were accustomed to the dark, and the contrast from Jupiter to Venus that night may have been a bit of a jump. It takes your eyes a while to adjust to changes in light level at night as your pupils are wide open.
